In winter of cold area, if the heater is idle for a long
period, please pull the handle of safety valve to discharge
the water. Otherwise it may freeze inside the water heater
and cause damages.
After installation, be sure to fill the heater completely with
water before switching on the power in the first usage.
Children must take bath under the supervision of adult.
In opening and closing the water valve, do not point
the shower head to human body. Otherwise it may
hurt by the spraying hot water.
Safety precaution: Do not confuse the
water inlet and outlet pipe. The wall bearing the
water heater shall be strong enough to endure a
weight twice as much as that of water heater
filled with water.
If any part is damaged, please contact the local
maintenance agent, and have it replaced with
our spare part.
If the water heater will be installed in the bathroom
without sewer, we suggest you add drain hose.
Fasten the drain hose to the drain thread of safety
valve by twisting (see to Figure 4). Connect the other
end of drain hose to the sewer to avoid polluting the
room by splashing. When the power is switched on,
and the water heater starts operating, there may be
some water discharged from the pressure relief hole
of safety valve. It is due to the water expansion under
heating, and is normal phenomenon. The pressure
relief pipe shall communicate with the air directly. Do
not block it. The discharged water can be led to the
sewer. The drain hose connecting to the safety valve
shall be kept downward sloping in installation and in a
frost-free environment.
Select suitable position on the wall to fix the shower
nozzle bearer. Connect the shower nozzle hose to the
pipeline. Fasten the mixing valve. Check if there's
water leakage at each joint.
Be sure to check and confirm that the tank is filled
with water, there's no leakage at each joint and the
power supply complies with the stipulation before
switching on the power.
