IV. DESCRIPTION AND PRINCIPLE OF WORK
The appliance consists of a body, ange at the
bottom side /for water heaters intended for vertical
mounting/ or at the sides /for water heaters intended
for horizontal mounting/, protective plastic panel
safety-return valve.
1. The body consists of a steel reservoir (water
tank) and housing (outer shell) with thermal
insulation placed in-between made of ecologically
clean high density polyurethane foam, and two
pipes with thread G ½ ‘’ for cold water supply
(marked by a blue ring) and hot water outlet pipe
(marked by a red ring).
The inner tank may be of two types depending on
the model:
•Made of steel protected form corrosion by a
special glass-ceramics coating
•Made of stainless steel
2. The ange is outtted with: electric heater and
thermostat. The water heaters with glass-ceramics
coating are outtted with a magnesium protector.
The electric heater is used for heating the water in
the tank and is managed by the thermostat, which
automatically maintains the set temperature.
The thermostat has a built in overheating safety
device, which switches of power to the heater when
the water temperature reaches excessive values.
In the event this device is tripped, please consult a
service station.
The magnesium protector provides additional
corrosion protection to the internal tank of heaters
outtted with glass-ceramics coating.
3. The safety-return valve prevents the appliance’s
complete emptying in the event the cold water
supply is interrupted. The valve protects the
appliance from pressure increases higher than the
allowed value during heating (! pressure increases
upon an increase of temperature), via release of
excess pressure during the drainage opening.
Attention! The safety-return valve cannot protect
the appliance in the event of water mains pressure
in excess of the acceptable pressure stated for
the appliance.
V. MOUNTING AND SWITCHING ON
Attention! Improper installation and connection of
the appliance may make it hazardous for the health
and life of consumers. It may cause grievous and
permanent consequences, including but not limited to
physical injuries and/or death. Improper installation and
connection of the appliance may also lead to damage to the
consumers’ property /damage and/ or destruction/, or to that
of third persons, as a result of, but not limited to ooding,
explosion and/or re. Installation, connection to the main
water and power supply, and putting into operation must be
carried out by certied electricians and technical personnel
certied in installation of this category of appliances, who
have obtained their license in the state where the installation
and commissioning of the appliance are carried out, and in
compliance with its local legislation.
1. Mounting
We recommend the mounting of the device at close
proximity to locations where hot water is used, in
order to reduce heat losses during transportation.
In the event the device is mounted in a bathroom,
the selected location must exclude the possibility
of water spray contact from the showerhead or
portable showerhead attachment.
The appliance is axed to a wall via the mounting
brackets attached to the unit’s body. Two hooks are
used for suspending the appliance (min. Ø 10 mm)
set rmly in the wall (not included in the mounting
set). The mounting bracket’s construction designed
for water heaters intended for vertical mounting is
universal and allows a distance between the hooks
of 220 to 310 mm (g. 1).
Attention
! In order to prevent injury to user and/or
third persons in the event of faults in the system for
providing hot water, the appliance must be mounted
in premises outtted with oor hydro insulation (or) plumbing
drainage. Don’t place objects, which are not waterproof
under the appliance under any circumstances. In the event
of mounting the appliance in premises not outtted with oor
hydro insulation, a protective tub with a plumbing drainage
must be placed under the appliance.
Notice: the set does not include a protective
tub and the user must select the same.
2. Water heater connection to the pipe network.
Fig. 4:
Where: A ≈4m ; 1 - Inlet pipe; 2 - Safety valve; 3 -
reducing valve (for water main pressure > 0,6 MPa);
4 - Stop valve; 5 - Funnel connected to the sewer
network; 6 – Hose; 7 - Drain water tap.
Upon connecting the water heater to the water
mains you must consider the indicative color
markings /rings/ axed to the pipes: blue for cold /
incoming/ water, red for hot /outgoing/ water.
The mounting of the safety return-valve supplied
with the water heater is obligatory. The safety
return-valve must be mounted on the cold water
supply pipe, in observance of the direction arrow
stamped on its body, indicating the incoming
water’s direction. Additional stopcocks must not be
mounted between the safety return-valve and the
water heater.
Exception: If the local regulations (norms)
require the usage of another protection valve or
mechanism (in accordance with EN 1487 or EN
1489), then it must be bought additionally. For
mechanisms operating in accordance with EN 1487
the announced operational pressure must be no
more than 0.7 MPa. For other protection valves, the
pressure at which they are calibrated must be 0.1
MPa lower than the one marked on the appliance’s
sign. In these cases the safety valve which the
appliance is supplied with should not be used.
Attention! The presence of other /old/ safety return-
valves may lead to a breakdown of your appliance
and they must be removed.
