The supply socket must be earthed reliably. The rated current of the socket
shall not be lower than 10A. The socket and plug shall be kept dry to
prevent electric leakage. Inspect frequently whether the plugs are well
plugged in the socket. Inspect method is as follows: insert the power
supply plug into the socket,after using for half an hour, shut down the unit
and pull the plug out, and inspect the plug in case it scalds your hand. If
tempeature is over 50, please plug in another socket. to avoid the plug
being damaged, fire or other personnel accidents result from badcontact.
For the places or the wall where the water
may splash, the installation
height of the socket shall not be lower than 1.8m.
The wall in which the electric water heater is installed shall be able to bear
the weight equalling twice the weight of the heater fully filled with water
without distortion or cracks. Otherwise, other strengthening measures
The one-way safety valve attached to the
machine must be installed to the
cold water inlet of this machine (see Fig.6).
should be adopted.
For the first use (or the first use after maintenance or cleaning), the heater
can not be switched on until it has been (fully) filled with water. When filling
with water, at least one of the outlet valves at the outlet of the heater
must
be opened to release the air. This valve can be closed after the heater has
been (fully) filled with water.
During the heating, there may be drops of water dripping from the pressure
release hole of the one-way safety valve. This is a normal phenomenon. If
there is a large amount of water leaking, please contact the professional
maintenance personnel for repair. This pressure release hole shall, under
no circumstances, be blocked; otherwise, the heater may be damaged,
even resulting in safety accidents.

power is restored, the water heater is restored to the shutdown status. In the
power state, the system can be self-checking automatically. If there is a fault,
the system does not work (i.e., the water heater cannot be started).
Diagnosis of dry burning fault: When the system detects that the inner tank
temperature is increasing more 15ºC/min or 8ºC/30S or more, and the
temperature is higher than 50ºC, the indicator lights 35, 55 and 75 will flash
to show that there is a dry burning fault.
Diagnosis of over-temperature fault: When the inner tank temperature is
over 90 degrees, it is judged to be over-temperature, and the five indicators
are flashing at the same time, indicating the failure "over-temperature".
Diagnosis of sensor fault: if the sensor is broken, all the five indicators will
flash from left to right to indicate the sensor fault.
