Operation
When
heating is required, either the unit or the boiler starts operating, depending on the outdoor temperature (refer to 10.7 field
setting/OTHER HEATING SOURCE).

109
8.6 Application 6
Dual setpoint function application with two room thermostat connect to the outdoor unit.
Make sure to correctly configure FOR SER
VICEMAN in the user interface. Refer to 10.7 Field settings/Other heating
source.
NOTE
Ensure that return water to
the heat exchanger does not exceed 60°C. Never put the target water flow temperature set
point on the user interface above 60°C.
Make sure that the non-return valves (field supply) are correctly installed in the system.
The supplier will not be held liable for any damage resulting from failure to observe this rule.
CAUTION
As the outdoor
temperature is measured via the outdoor unit air thermistor, make sure to install the outdoor unit in the shade,
so that it is not influenced by the sun’s heat.
Frequent switching can cause corrosion of the boiler at an early stage. Contact the boiler manufacturer.
During heating operation of the unit, the unit will operate to achieve the target water flow temperature set on the user
interface. When weather dependent operation is active, the water temperature is determined automatically depending on the
outdoor temperature.
During heating operation of the boiler, the boiler will operate to achieve the target water flow temperature set on the user
interface.
Never set the target water flow temperature set point on the user interface above (60°C).
Space heating with two room thermostat application through floor heating loops and fan coil units. The floor heating loops
and fan coil units require different operating water temperatures.
The floor heating loops require a lower water temperature in heating mode compared to fan coil units. To achieve these two
set points, a mixing station is used to adapt the water temperature according to requirements of the floor heating loops. The
fan coil units are directly connected to the unit water circuit and the floor heating loops are after the mixing station. Control
of this mixing station is not done by the unit.
The operation and configuration of the field water circuit is the responsibility of the installer.
We only offer a dual set point control function. This function allows two set points to be generated. Depending on the required
water temperature (floor heating loops and/or fan coil units are required) the first set point(set on the user interface) or
second set point(calculate from climate related curves) can be activated. More details refer to 10.7 field setting /ROOM
THERMOSTAT.
The wiring
of room thermostat 5A(for fan coil units) and 5B(for floor eating loops) should follow 'method C' as described
in 9.7.6 Connection for other components/For room thermostat, and the thermostat which connect to port 'C' (in the
outdoor unit) should be placed on the zone where floor heating loops is installed(zone B), the other one connect to port
'H' should be placed on the zone where fan coil units are installed(zone A).
NOTE
110
NOTE
The volume
of balance tank(8) should be greater than 40L(for 5~9kW unit, greater than 20L) The drain valve (6)
should be installed at the lowest positon of the system. An independent backup heater can be selected and installed
in the door. pump(10) and pump(23.1) should be controlled by outdoor unit and connect to corresponding port in the
outdoor unit(refer to 9.7.6 Connection for other components/For outside circulation pump P_o and For tank loop
pump P_d and mix pump P_c).
The advantage of the dual set point control is that the heat pump will/can operate at the lowest required water flow
temperature when only floor heating is required. Higher water flow temperatures are only required in case fan coil
units are operating. This results in better heat pump performance.
Pump operation and space heating
The pump (1.8) and (10) will operate when there is request for heating from A and/or B. Pump (23.1) will operate only when
there
is request for heating from B. The outdoor unit will start operating to achieve the target water flow temperature. The target
water leaving temperature depends on which room thermostat is requesting heating.
When the room temperature of both zones is above the thermostat set point, the outdoor unit and pump will stop operating.

It is the installers’ responsibility to ensure that no unwanted situations can occur (e.g. extremely high temperature
water going towards floor heating loops, etc.)
The supplier does not offer any type of mixing station. Dual set point control only provides the possibility to use two
set points.
When only zone A requests heating, zone B will be fed with water at a temperature equal to the first set point. This
can lead to unwanted heating in zone B.
When only zone B requests heating, the mixing station will be fed with water at a temperature equal to the second
set point.Depending on the control of the mixing station, the floor heating loop can still receive water at a
temperature equal to the set point of the mixing station.
Be aware that the actual water temperature through the floor heating loops depends on the control and setting of
the mixing station.
8.7 Application 7
Dual setpoint function application without room thermostat connect to the outdoor unit.

As
the temperature sensor attached in the user interface is used to detect the room temperature, the user interface
(4) should be placed in the room where floor heating loops and fan coil units is installed and away from the heating
source. Correct configuration should be applied in the user interface (refer to 10.7 field settings/TEMP. TYPE
SETTING). The first setpoint is water temperature which can be set on the main page of user interface, the second
setpoint is calculated from climate related curves, the target outlet water temperature is the higher one of these two
setpoints. The unit will turn off when the room temperature reaches the target temperature.

9.4 Water piping
All piping lengths and distances have been taken into consideration.
ValveRequirements
Thermistor cable length minus 2m
The maximum allowed
thermistor cable length is 20m. This is the maximum
allowable distance between the domestic hot water tank and the unit (only for
installations with a domestic hot water tank).The thermistor cable supplied with
the domestic hot water tank is 10m in length.In order to optimize efficiency we
recommend installing the 3-way valve and the domestic hot water tank as close
as possible to the unit.

The units are equipped with a water inlet and outlet for connection to a water circuit.
The units should only be connected to closed water circuits. Connection to an open water circuit would lead to excessive
corrosion of the water piping. Only materials complying with all applicable legislation should be used.
Example
If
the installation is equipped with a domestic hot water tank (field supply), please refer to the domestic hot water tank
Installation And Owner's Manual. If there is no glycol (anti-freeze) in the system there is a power supply or pump failure,
drain the system (as shown in the figure below).
NOTE
If water is not removed from the system in freezing weather when unit is not used. The frozen water may damage the
water circle parts.
NOTE
124
Always use materials that are compatible with the water used in the system and with the materials used in the unit.
Ensure that components installed in the field piping can withstand the water pressure and temperature.
Drain taps must be provided at all low points of the system to permit complete drainage of the circuit during maintenance.
Air vents must be provided
at all high points of the system. The vents should be located at points that are easily accessible
for service. An automatic air purge is provided inside the unit. Check that this air purge valve is not tightened so that
automatic release of air in the water circuit is possible.
Before continuing installation of the unit, check the following:
The units are equipped
with an expansion vessel (5/7/9kW models:2L; 12/14/16kW models:5L) that has a default pre-pressure
of 1.5 bar. To assure proper operation of the unit, the pre-pressure of the expansion vessel might need to be adjusted.
1) Check that the total water volume in the installation, excluding the internal water volume of the unit, is at least 25L(for 5/7/9
kW unit, the minimum volume is 15L) . Refer to 14 Technical specifications to find the total internal water volume of the unit.
2) Using the table below, determine if the expansion vessel pre- pressure requires adjustment.
3) Using the
table and instructions below, determine if the total water volume in the installation is below the maximum allowed
water volume.

maximum allowed water volume (use graph below)
Heighe difference is between the highest point of the wateer circuit and the outdoor unit's expansion tank. Unless the unit is
located at the highest point of the system, in which case the installation height differnce is considered to be zero.
For 1-phase 12~16kW and 3-phase 12~16kW units, this value is 72L, for 5~9kW units, this value is 30 L.
Calculating the pre-pressure of the expansion vessel
The pre-pressure
(Pg) to be set depends on the maximum installation height difference (H) and is calculated as follows:
Pg(bar)=(H(m)/10+0.3) bar
Checking the maximum allowed water volume
To determine the maximum allowed water volume in the entire circuit, proceed as follows:
NOTE
In most applications this minimum water volume will be satisfactory
.
In critical processes or in rooms with a high heat load though, extra water might be required.
When circulation in each space heating loop is controlled by remotely controlled valves, it is important that this
minimum water volume is kept even if all the valves are closed.
125
Be careful not to deform the unit’s piping by
using excessive force when connecting the
piping. Deforming the piping can cause the unit
to malfunction.
CAUTION
Selecting the additional expansion vessel
If the expansion
vessel of the unit is too small for the
installation, an additional expansion vessel is needed.
calculate the pre-pressure of the expansion vessel:
Pg(bar)=(H(m)/10+0.3) bar
the expansion vessel equipped in the unit should
adjust the pre- pressure also.
calculate the volume needed of the additional expan-
sion vessel:
V1=0.0693*Vwater/(2.5-Pg)-V0
Vwater is volume of water in the system, V0 is volume
of expansion vessel which the unit is
equipped(10~16kW,V0=5L, 5~9kW,V0=2L).
9.4.3 Water circuit connection
Water connections
must be made correctly in
accordance with labels on the outdoor unit, with respect
to the water inlet and water outlet.
Use clean pipes only.
Hold the pipe end downwards when removing burrs.
Cover the pipe end when inserting it through a wall to
prevent dust and dirt entering.
Use a good thread sealant for sealing the
connections. The sealing must be able to withstand
the pressures and temperatures of the system.
When using non-copper metallic piping, be sure to
insulate two kind of materials from each other to
prevent galvanic corrosion.
If air, moisture
or dust gets in the water circuit, problems
may occur. Therefore, always take into account the
following when connecting the water circuit:
For copper is a soft material,
use appropriate tools for
connecting the water circuit.
Inappropriate tools will cause
damage to the pipes.
Pre-pressure = pre-pressure of the expansion vessel

= maximum water volume in the
system
A1 System without glycol for 1-phase 12~16 kW
and 3-phase 12~16 kW unit
A2 System without glycol for the 5/7/9 kW unit
Example 1
The
unit(16kW) is installed 10m below the highest point
in the water circuit. The total water volume in the water
circuit is 50 L. In this example, no action or adjustment is
required.
Example 2
The unit(16kW)
is installed at the highest point in the
water circuit. The total water volume in the water circuit is
150 L.
Result:
Since 150 L is more than 72 L, the pre-pressure must
be decreased (see table above).
The required pre-pressure is: Pg(bar) =
(H(m)/10+0.3) bar = (0/10+0.3) bar = 0.3 bar
The corresponding maximum water volume can be
read from the graph: approximately 160 L.
Since the total water volume (150 L) is below the
maximum water volume (160 L), the expansion
vessel suffices for the installation.
Setting the pre-pressure of the expansion vessel
When it
is required to change the default pre-pressure of
the expansion vessel (1.5 bar), following guidelines:
Use only dry nitrogen to set the expansion vessel
pre-pressure.
Inappropriate setting of the expansion vessel
pre-pressure will lead to malfunctioning of the
system. Pre-pressure should only be adjusted by a
licensed installer.

Determine the calculated
pre-pressure (Pg) for the
corresponding maximum water volume using the
graph below.
Check that the total water volume in the entire water
circuit is lower than this value. If this is not the case,
the expansion vessel inside the unit is too small for
the installation.
NOTE
Never use Zn-coated parts in the water
circuit. Excessive
corrosion of these parts
may occur as copper piping is used in the
unit's internal water circuit.
When using a 3-way valve in the water circuit.
Preferably choose a ball type 3-way valve to
guarantee full separation between the
domestic hot water and floor heating water
circuit.
When using a 3-way valve or a 2-way valve in
the water circuit. The recommended
maximum changeover time of the valve
should be less than 60 seconds.
The unit is only to be used in a closed water
system. Application in an open water circuit can
lead to excessive corrosion of the water piping:
126
9.4.4 Water circuit anti-freeze protection
Ice formation can cause damage to the hydraulic system. As the outdoor unit may be exposed to sub-zero temperatures, care
must be taken to prevent freezing of the system.
All internal hydronic parts are insulated to reduce heat loss. Insulation must also be added to the field piping.
The software contains special functions using the heat pump to protect the entire system against freezing. When the
temperature of the water flow in the system drops to a certain value, the unit will heat the water, either using the heat pump,
the electric heating tap, or the backup heater. The freeze protection function will turn off only when the temperature
increases to a certain value.
In event of a power failure, the above features would not protect the unit from freezing.
Since a power failure could happen when the
unit is unattended,the supplier recommends use anti-freeze fluid to the water
system. Refer to “Caution: Use of glycol” .
Depending on the expected lowest outdoor temperature, make sure the water system is filled with a concentration of glycol as
mentioned in the table below.
When glycol is added to the system, the performance of the unit will be affected. The correction factor of the unit capacity, flow
rate and pressure drop of the system is listed in the table below.
Ethylene Glycol and Propylene Glycol are
TOXIC
The concentrations mentioned in the table above will not prevent freezing, but will prevent the hydraulics from bursting.
WARNING
Ethylene Glycol
Propylene Glycol
If no glycol is added, the water must be drained out when there is a power failure.
Water may enter into the flow switch and
cannot be drained out and may freeze when the temperature is low enough. The flow
switch should be removed and dried, then can be reinstalled in the unit.

That
the water treatment is correctly executed by a
qualified water specialist.
That a glycol with corrosion inhibitors is selected to
counteract acids formed by the oxidation of glycols.
That in case of an installation with a domestic hot
water tank, only the use of propylene glycol is
allowed. In other installations the use of ethylene
glycol is fine.
That no automotive glycol is used because their
corrosion inhibitors have a limited lifetime and contain
silicates that can foul or plug the system.
That galvanized piping is not used in glycol systems
since it may lead to the precipitation of certain
elements in the glycol’s corrosion inhibitor.
To ensure that the glycol is compatible with the
materials used in the system.
Also refer to
"10.3 Pre-operation checks/Checks before
initial start-up".
Be aware of the hygroscopic
property of
glycol. It absorbs moisture from the environ-
ment.
Leaving the cap off the glycol container
causes the concentration of water to
increase. The glycol concentration is then
lower and the water could freeze.
Preventive actions must be taken to ensure
minimal exposure of the glycol to air.
NOTE
Connect
the water supply to the fill valve and open
the valve.
Make sure the automatic air purge valve is open (at
least 2 turns).
Fill with water until the manometer indicates a
pressure of approximately 2.0 bar. Remove air in the
circuit as much as possible using the air purge
valves. Air in the water circuit could lead to
malfunction of the backup electric heater.
9.5 Adding water
Do not fasten the black plastic
cover on the vent valve at the
topside of the unit when the
system is running. Open air
purge valve, turn anticlockWise
at
least 2 full turns to release air
from the system.
Corrosion in the system due to glycol
Uninhibited
glycol will turn acidic under the influence of
oxygen. This process is accelerated by presence of
copper and at higher temperatures. The acidic
uninhibited glycol attacks metal surfaces and forms
galvanic corrosion cells that cause severe damage to the
system. It is of extreme importance:
CAUTION
Glycol use for installations with a domestic
hot water tank: Only propylene glycol
having
a toxicity rating or class of 1, as
listed in "Clinical Toxicology of Commercial
Products, 5th edition" may be used. The
maximum allowed water volume is then
reduced according to the figure on page
36.
If there is too much pressure when using
glycol, connect the safety valve to a drain
pan to recover the glycol.
CounterclockWise rotation, remove the
flow
switch.
Drying the flow switch completely.
NOTE
Keep dry
Use of glycol
128
A
main switch or other means of disconnection, having a contact separation in all poles, must be incorporated in the
fixed wiring in accordance with relevant local laws and regulations. Switch off the power supply before making any
connections. Use only copper wires. Never squeeze bundled cables and make sure they do not come in contact with
the piping and sharp edges. Make sure no external pressure is applied to the terminal connections. All field wiring and
components must be installed by a licensed electrician and must comply with relevant local laws and regulations.
The field wiring must be carried out in accordance with the wiring diagram supplied with the unit and the instructions
given below.
Be sure to use a dedicated power supply. Never use a power supply shared by another appliance.
Be sure to establish a ground. Do not ground the unit to a utility pipe, surge protector, or telephone ground. Incomplete
grounding may cause electrical shock.
Be sure to install a ground fault circuit interrupter (30 mA). Failure to do so may cause electrical shock.
Be sure to install the required fuses or circuit breakers.
WARNING
9.7.2 Wiring overview
The ground fault circuit interrupter must be a high- speed type breaker of 30 mA
(<0.1 s).
NOTE
This unit is equipped with an inverter. Installing a phase advancing capacitor not only will reduce the power factor improve-
ment effect,
but also may cause abnormal heating of the capacitor due to high-frequency waves. Never install a phase
advancing capacitor as it could lead to an accident.
The illustration below gives an overview of the required field wiring between several parts of the installation. Refer also to "8
Typical application examples".
Secure the electrical wiring with cable ties as shown in figure so that it does not come in contact with the piping, particularly
on the high-pressure side.
Make sure no external pressure is applied to the terminal connectors.
When installing the ground fault circuit interrupter make sure that it is compatible with the inverter (resistant to high frequency
electrical noise) to avoid unnecessary opening of the ground fault circuit interrupter.
Fix cables so that cables do not make contact with the pipes (especially on the high pressure side).
9.7.1 Precautions on electrical wiring work
9.6 Water piping insulation
9.7 Field wiring
The complete water circuit including
all piping, water piping must be insulated to prevent condensation during cooling operation
and reduction of the heating and cooling capacity as well as prevention of freezing of the outside water piping during winter. The
insulation material should at least of B1 fire resistance rating and complies with all applicable legislation. The thickness of the
sealing materials must be at least 13 mm with thermal conductivity 0.039 W/mK in order to prevent freezing on the outside water
piping.
If the outdoor ambient temperature is higher than 30°C and the humidity is higher than RH 80%, then the thickness of the
sealing materials should be at least 20 mm in order to avoid condensation on the surface of the seal.
NOTE
During filling, it
might not be possible to remove all air in the system. Remaining air will be removed through the
automatic air purge valves during the first operating hours of the system. Topping up the water afterwards might be
required.
The water pressure indicated on the manometer will vary depending on the water temperature (higher pressure at
higher water temperature). However, at all times water pressure should remain above 0.3 bar to avoid air entering
the circuit.
The unit might drain-off too much water through the pressure relief valve.
Water quality should be complied with EN 98/83 EC Directives.
Detailed water quality condition can be found in EN 98/83 EC Directives.

During
initial start-up and when water temperature is low, it is important that the water is heated gradually. Failure to do so may
result in concrete floors cracking due to rapid temperature change. Please contact the responsible cast concrete building
contractor for further details.
To do so, the lowest water flow set temperature can be decreased to a value between 25°C and 35°C by adjusting the FOR
SERVICEMAN. Refer to "FOR SERVICEMAN/special function/preheating for floor" .
Checks before initial start-up.
10.3 Initial start-up at low outdoor ambient temperature
10.4 Pre-operation checks

When power to the unit is turned on, "1%~99%"
is displayed on the user interface during initialization. During this process the
user interface cannot be operated.
10.5 Powering up the unit
DANGER
Switch of
f the power supply before making any connections.
After the installation of the unit, check the following before switching on the circuit breaker:
Field wiring Make sure that the field wiring between the local supply panel and unit and valves (when applicable),
unit and room thermostat (when applicable), unit and domestic hot water tank, and unit and backup heater kit have
been connected according to the instructions described in the chapter 9.6 Field wiring, according to the wiring
diagrams and to local laws and regulations.
Fuses, circuit breakers, or protection devices Check that the fuses or the locally installed protection devices are of
the size and type specified in the chapter 14 Technical specifications. Make sure that no fuses or protection devices
have been bypassed.
Backup heater circuit breaker Do not forget to turn on the backup heater circuit breaker in the switchbox (it
depends on the backup heater type). Refer to the wiring diagram.
Booster heater circuit breaker Do not forget to turn on the booster heater circuit breaker (applies only to units with
optional domestic hot water tank installed).
Ground wiring Make sure that the ground wires have been connected properly and that the ground terminals are
tightened.
Internal wiring Visually check the switch box for loose connections or damaged electrical components.
Mounting Check that the unit is properly mounted, to avoid abnormal noises and vibrations when starting up the
unit.
Damaged equipment Check the inside of the unit for damaged components or squeezed pipes.
Refrigerant leak Check the inside of the unit for refrigerant leakage. If there is a refrigerant leak, call your local
dealer.
Power supply voltage Check the power supply voltage on the local supply panel. The voltage must correspond to
the voltage on the identification label of the unit.
Air purge valve Make sure the air purge valve is open (at least 2 turns).
Shut-off valves Make sure that the shut-off valves are fully open.
The pump speed can be selected by adjusting
the red knob on the pump. The notch point indicates
pump speed.
The default setting is the highest speed (III). If the water flow in the system is too high the speed can
be set to low (I).
The available external static pressure function for water flow is shown in the graph below.

2) Failure diagnosis at the moment of first installation
If
nothing is displayed on the user interface, it is necessary to check for any of the following abnormalities before diagnosing
possible error codes.
-Disconnection or wiring error (between power supply and unit and between unit and user interface).
-The fuse on the PCB may have blown.
If the user interface shows "E8"or"E0" as an error code, there is a possibility that there is air in the system, or the water level
in the system is less than the required minimum.
If the error code E2 is displayed on the user interface, check the wiring between the user interface and unit.
More error code and failure causes can be found in 13.4 Error codes.
The unit shall be configured
by the installer to match the installation environment (outdoor climate, installed options, etc.) and
user demand. A number of field settings are available. These settings are accessible and programmable through “FOR
SERVICEMAN” in user interface.

DANGER
Operating the system with closed valves will damage the circulation pump!
DANGER
If it's necessary to check the running status of the pump when unit power on. please do not touch the internal electronic
control box components to avoid electric shock.
If the LED display lights up continuously green, it means the pump is running normally.
If the LED display is flashing green, it means the pump is running the venting function. The pump runs during the 10 minute
venting function. After its cycle, the installer needs to adjust the targeted performance.
If the LED is flashing green/red, it means that the pump has stopped operating due to an external reason. The pump will
restart by itself after the abnormal situation disappears. The probable reason causing the problem is pump undervoltage or
overvoltage (U<160V or U>280V), and you should check the voltage supply. Another reason is module overheating, and you
should check the water and ambient temperatures.
If the LED is flashing red, it means the pump has stopped operating, and a serious fault has happened (e.g. pump blocked).
The pump cannot restart itself due to a permanent failure and the pump should be changed.
If the LED does not light up, it means no power supply to the pump, possibly the pump is not connected to power supply.
Check the cable connection. If the pump is still running, it means the LED is damaged. Or the electronics are damaged and
the pump should be changed.
1) Pump LED diagnosis and solutions
The pump
has an LED operating status display. This makes it easy for the technician to search for the cause of a fault in the
heating system.

11.2 Test run operation (manually)
That during
the first running period of the unit,
required power input may be higher than stated
on the nameplate of the unit. This phenomenon
originates from the compressor that needs
elapse of a 50 hours run in period before
reaching smooth operation and stable power
consumption.
NOTE
In
order to ensure optimal availability of the unit, a number
of checks and inspections on the unit and the field wiring
have to be carried out at regular intervals.
This maintenance needs to be carried out by your local
technician.

13 TROUBLE SHOOTING
13.1 General guidelines
Make sure that
the disposal of the glycol solution is done
in accordance with relevant local laws and regulations.
Water pressure
Check the
water pressure, if it is below 1 bar,fill water
to the system.
Water filter
Clean the water filter.
Water pressure relief valve
Check for correct operation of the pressure relief
valve by turning the black knob on the valve
counter-clockWise:
-If you do not hear a clacking sound, contact your
local dealer.
-In case the water keeps running out of the unit, close
both the water inlet and outlet shut-off valves first and
then contact your local dealer.
Pressure relief valve hose
Check that the pressure relief valve hose is
positioned appropriately to drain the water.
Backup heater vessel insulation cover
Check that the backup heater insulation cover is
fastened tightly around the backup heater vessel.
Domestic hot water tank pressure relief valve (field
supply) Applies only to installations with a domestic
hot water tank. Check for correct operation of the
pressure relief valve on the domestic hot water tank.
Domestic hot water tank booster heater
Applies only to installations with a domestic hot water
tank. It is advisable to remove lime buildup on the
booster heater to extend its life span, especially in
regions with hard water. To do so, drain the domestic
hot water tank, remove the booster heater from the
domestic hot water tank and immerse in a bucket (or
similar) with lime-removing product for 24 hours.
Unit switch box
-Carry out a thorough visual inspection of the switch
box and look for obvious defects such as loose
connections or defective wiring.
-Check for correct operation of contactors with an
ohm meter. All contacts of these contactors must be
in open position.
Use of glycol (Refer to 9.3 Water pipework Caution:
"Use of glycol" ) Document the glycol concentration
and the pH-value in the system at least once a year.
-A PH-value below 8.0 indicates that a significant
portion of the inhibitor has been depleted and that
more inhibitor needs to be added.
-When the PH-value is below 7.0 then oxidation of the
glycol occurred, the system should be drained and
flushed thoroughly before severe damage occurs.
The following
checks must be performed at least once a
year by qualified person.
157
When a safety
device was activated, stop the unit and find out why the safety device was activated before resetting it. Under no
circumstances can safety devices be bridged or changed to a value other than the factory setting. If the cause of the problem
cannot be found, call your local dealer.
If the pressure relief valve is not working correctly and is to be replaced, always reconnect the flexible hose attached to the
pressure relief valve to avoid water dripping out of the unit!
Before starting the troubleshooting procedure, carry out a thorough visual inspection of the unit and look for obvious defects
such as loose connections or defective wiring.
For
problems related to the optional solar kit for domestic water heating, refer to the troubleshooting in the Installation
& Owner's manual for that kit.
NOTE
When carrying out an inspection
on the switch box of the unit, always make sure that the main switch of the unit is
switched off.

16 INFORMATION SERVICING
15 REPLACEMENT OF SAFETY VALVE (Only for 12~16kW units)
1) Checks to the area
Prior to beginning
work on systems containing flammable refrigerants, safety checks are necessary to ensure that the risk of
ignition is minmised. For repair to the refrigerating system, the following precautions shall be complied with prior to conducting
work on the system.
2) Work procedure
Works shall be undertaken under a controlled procedure so as to minimise the risk of a flammable gas or vapour being present
while the work is being performed.
3) General work area
All mintenance staff and others working in the local area shall be instructed on the nature of work being carried out. work in
confined sapces shall be avoided. The area around the work space shall be sectioned off. Ensure that the conditions within the
area have been made safe by control of flammable material.
4) Checking for presence of refrigerant
The area shall be checked with an appropriate refrigerant detector prior to and during work, to ensure the technician is aware
of potentially flammable atmospheres. Ensure that the leak detection equipment being used is suitable for use with flammable
refrigerants, i.e. no sparking, adequately sealed or intrinsically safe.
5) Presence of fire extinguisher
If any hot work is to be conducted on the refrigeration equipment or any associated parts, appropriate fire extinguishing
equipment shall be available to hand. Have a dry power or CO
2
fire extinguisher adjacent to the charging area.
6) No ignition sources
No person
carrying out work in relation to a refrigeration system which involves exposing any pipe work that contains or has
contained flammable refrigerant shall use any sources of ignition in such a manner that it may lead to the risk of fire or explosion.
All possible ignition sources, including cigarette smoking, should be kept sufficiently far away from the site of installation,
repairing, removing and disposal, during which flammable refrigerant can possibly be released to the surrounding space. Prior
to work taking place, the area around the equipment is to be surveyed to make sure that there are no flammable hazards or
ignition risks. NO SMOKING signs shall be displayed.
Visual inspection is needed after that period, maintenance people should check the appearance of the valve body and the
operating environment. If the valve body is not obvious corrosion, cracks, dirt, damage, then the valve can be used continually.
Otherwise, please contact your supplier for spare part.
Replace the safety valve as follows (Suitable for type with safety valve):
1) Reclaim the refrigerant completely in the system. Doing so requires professional staff and equipment;
2) Note to protect the tank coating. Avoid damage to coating from external force or high temperature when removing and
installing the safety valve;
3) Heat the sealant to screw off the safety valve. Note to protect the area where the screwing tool meets the tank body and avoid
damages to the tank coating;
4) If tank coating is damaged, repaint the damaged area.
S
afety Valve
168
7) Ventilated area
Ensure that
the area is in the open or that it it adequately ventilated before breaking into the system or conducting any hot work.
A degree of ventilation shall continue during the period that the work is carried out. The ventilation should safely disperse any
released refrigerant and preferably expel it externally into the atmosphere.
8) Checks to the refrigeration equipment
Where electrical components are being changed, they shall be fit for the purpose and to the correct specification. At all times
the manufacturer s maintenance and service guidelines shall be followed. If in doubt consult the manufacturer s technical
department for assistance. The following checks shall be applied to installations using flammable refrigerants:
a) During repairs to sealed components, all electrical supplies shall be disconnected from the equipment being worked upon
prior to any removal of sealed covers, etc. If it is absolutely necessary to have an electrical supply to equipment during servicing,
then a permanently operating form of leak detection shall be located at the most critical point to warn of a potentially hazardous
situation.
b) Particular attention shall be paid to the following to ensure that by working on electrical components, the casing is not altered
in such a way that the level of protection is affected. This shall include damage to cables, excessive number of connections,
terminals not made to original specification, damage to seals, incorrect fitting of glands, etc.
9) Checks to electrical devices
Repair and maintenance to electrical components shall include initial safety checks and component inspection procedures. If a
fault exists that could compromise safety, then no electrical supply shall be connected to the circuit until it is satisfactorily dealt
with. If the fault cannot be corrected immediately but it is necessary to continue operation, and adequate temporary solution
shall be used. This shall be reported to the owner of the equipment so all parties are advised.
Initial safety checks shall include:
10) Repairs to sealed components
The charge size is in accordance with the room size within which the refrigerant containing parts are installed;
The ventilation machinery and outlets are operating adequately and are not obstructed;
If an indirect refrigerating circuit is being used, the secondary circuits shall be checked for the presence of refrigerant;
marking to the equipment continues to be visible and legible.
Marking and signs that are illegible shall be corrected;
Refrigeration pipe or components are installed in a position where they are unlikely to be exposed to any substance which
may corrode refrigerant containing components, unless the components are constructed of materials which are inherently
resistant to being corroded or are suitably protected against being so corroded.
That capacitors are discharged: this shall be done in a safe manner to avoid possibility of sparking;
That there no live electrical components and wiring are exposed while charging, recovering or purging the system;
That there is continuity of earth bonding.
Ensure that apparatus is mounted securely.
Ensure that seals or sealing
materials have not degraded such that they no longer serve the purpose of preventing the
ingress of flammable atmospheres. Replacement parts shall be in accordance with the manufacturer s specifications.
11) Repair to intrinsically safe components
Do not apply
any permanent inductive or capacitance loads to the circuit without ensuring that this will not exceed the
permissible voltage and current permitted for the equipment in use. Intrinscially safe components are the only types that can be
worked on while live in the presence of a flammable atmosphere. The test apparatus shall be at the correct rating. Replace
components only with parts specified by the manufacturer. Other parts may result in the ignition of refrigerant in the atmosphere
from a leak.
12) Cabling
Check that cabling will not be subject to wear, corrosion, excessive pressure, vibration, sharp edges or any other adverse
environmental effects. The check shall also take into account the effects of aging or continual vibration from sources such as
compressors or fans.
13) Detection of flammable refrigerants
Under no circumstances shall potential sources of ignition be used in the searching for or detection of refrigerant leaks. A halide
The use of silicon
sealant may inhibit the effectiveness of some types of leak detection equipment. Instrinsically safe
components do not have to be isolated prior to working on them.
NOTE
169
17) Decommissioning
Before carrying out this procedure, it is essential that
the technician is completely familiar with the equipment and all its detail.
It is recommended good practice that all refrigerants are recovered safely. Prior to the task being carried out, an oil and
refrigerant sample shall be taken.
In case analysis is required prior to re-use of reclaimed refrigerant. It is essential that electrical power is available before the
task is commenced.
a) Become familiar with the equipment and its operation.
b) Isolate system electrically
c) Before attempting the procedure ensure that:
Mechanical handling equipment is available, if required, for handling refrigerant cylinders;
All personal protetive equipment is available and being used correctly;
The recovery process is supervised at all times by a competent person;
Recovery equipment and cylinders conform to the appropriate standards.
The refrigerant
charge shall be recovered into the correct recovery cylinders. The system shall be flushed with OFN to render
the unit safe. This process may need to be repeated several times.
Compressed air or oxygen shall not be used for this task.
Flushing shall be achieved by breaking the vacuum in the system with OFN and continuing to fill until the working pressure is
achieved, then venting to atmosphere, and finally pulling down to a vacuum. This process shall be repeated until no refrigerant
is within the system.
When the final OFN charge is used, the system shall be vented down to atmospheric pressure to enable work to take place.
This operation is absolutely vital if brazing operations on the pipe-work are to take place.
Ensure that the outlet for the vacuum pump is not closed to any ignition sources and there is ventilation available.
16) Charging procedures
In addition to conventional charging procedures, the following requirements shall be followed:
14) Leak detection methods
The following leak detection methods are deemed acceptable for systems containing flammable refrigerants. Electronic leak
detectors shall be used to detect flammable refrigerants, but the sensitivity may not be adequate, or may need
re-calibration.(Detection equipment shall be calibrated in a refrigerant-free area.) Ensure that the detector is not a potential
source of ignition and is suitable for the refrigerant. Leak detection equipment shall be set at a percentage of the LFL of the
refrigerant and shall be calibrated to the refrigerant employed and the appropriate percentage of gas (25% maximum) is
confirmed. Leak detection fluids are suitable for use with most refrigerants but the use of detergents containing chlorine shall
be avoided as the chlorine may react with the refrigerant and corrode the copper pipe-work. If a leak is suspected ,all naked
flames shall be removed or extinguished. If a leakage of refrigernat is found which requires brazing, all of the refrigerant shall
be recovered from the system, or isolated(by means of shut off valves) in a part of the system remote from the leak . Oxygen
free
nitrogen(OFN) shall then be purged through the system both before and during the brazing process.
15) Removal and evacuation
When breaking into the refrigerant circuit to make repairs of for any other purpose conventional procedures shall be used,
However, it is important that best practice is followed since flammability is a consideration. The following procedure shall be
Ensure that contamination of different refrigerants does not occur when using charging equipment. Hoses or lines shall be
as short as possible to minimize the amount of refrigerant contained in them.
Cylinders shall be kept upright.
Ensure that the refrigeration system is earthed prior to charging the system with refrigerant.
Label the system when charging is complete(if not already).
Extreme care shall be taken not to overfill the refrigeration system.
Prior to recharging the system it shall be pressure tested with OFN. The system shall be leak tested on completion of
charging but prior to commissioning. A follow up leak test shall be carried out prior to leaving the site.
Remove refrigerant;
Purge the circuit with inert gas;
Evacuate;
Purge again with inert gas;
Open the circuit by cutting or brazing.
d) Pump down refrigerant system, if possible.
e) If a vacuum is not possible, make a manifold so that refrigerant can be removed from various parts of the system.
f) Make sure that cylinder is situated on the scales before recovery takes place.
g) Start the recovery machine and operate in accordance with manufacturer s instructions.
h) Do not overfill cylinders. (No more than 80% volume liquid charge).
i) Do not exceed the maximum working pressure of the cylinder, even temporarily.
j) When the cylinders
have been filled correctly and the process completed, make sure that the cylinders and the equipment are
removed from site promptly and all isolation valves on the equipment are closed off.
k) Recovered refrigerant shall not be charged into another refrigeration system unless it has been cleaned and checked.
170
18) Labelling
Equipment
shall be labelled stating that it has been de-commissioned and emptied of refrigerant. The label shall be dated and
signed. Ensure that there are labels on the equipment stating the equipment contains flammable refrigerant.
19) Recovery
When removing refrigerant from a system, either for service or decommissioning, it is recommended good practice that all
refrigerants are removed safely.
When tranferring refrigerant into cylinders, ensure that only appropriate refrigerant recovery cylinders are employed. Ensure
that the correct numbers of cylinders for holding the total system charge are available. All cylinders to be used are designated
for the recovered refrigerant and labelled for that refrigerant(i.e special cylinders for the recovery of refrigerant). Cylinders shall
be complete with pressure relief valve and associated shut-off valves in good working order.
Empty recovery cylinders are evacuated and, if possible, cooled before recovery occurs.
The recovery equipment shall be in good working order with a set of instructions concerning the equipment that is at hand and
shall be suitable for the recovery of flammable refrigerants. In addition, a set of calibrated weighing scales shall be available and
in good working order.
Hoses shall be complete with leak-free disconnect couplings and in good condition. Before using the recovery machine, check
that it is in satisfactory working order, has been properly maintained and that any associated electrical components are sealed
to prevent ignition in the event of a refrigerant release. Consult manufacturer if in doubt.
The recovered refrigerant shall be returned to the refrigerant supplier in the correct recovery cylinder, and the relevant Waste
Transfer Note arranged. Do not mix refrigerants in recovery units and especially not in cylinders.
If compressors or compressor oils are to be removed, ensure that they have been evacuated to an acceptable level to make
certain that flammable refrigerant does not remain within the lubricant. The evacuation process shall be carried out prior to
retruning the compressor to the suppliers. Only electric heating to the compressor body shall be employed to accelerate this
process. When oil is drained from a system, it shall be carried out safely.
20) Transportation, marking and storage for units
Transport of equipment containing flammable refrigerants Compliance with the transport regulations
Marking of equipment using signs Compliance with local regulations
Disposal of equipment using flammable refrigerants Compliance with national regulations
Storage of equipment/appliances
The storage of equipment should be in accordance with the manufacturer’s instructions.
Storage of packed (unsold) equipment
Storage package protection should be constructed such that mechanical damage to the equipment inside the package will not
cause a leak of the refrigerant charge.
The maximum number of pieces of equipment permitted to be stored together will be determined by local regulations.
