If the mains pressure of water is close to the
setting of the safety valve, please install a
pressure reducing valve (F) on the water supply
pipe end away from the water heater (see Fig. 8).
=
If a valve is installed on the supply pipe, keep
the valve open normally.

rate of the water is close to the water supplying flow-rate, which means the water heater is fully
filled with water. Turn off the outlet valve and keep the inlet valve normally open.
Caution :
Before switching the heater on, make sure that the tank is full of water and that there
is no any water leakage in whole system.

Repairing and maintenance
All maintenance works must be carried out by qualified personnel.
Before contacting local Service Agency, please make sure that the problem is not due to temporary

If the power cannot be supplied to the heater, the dual thermal protecting switch may be activated
and the mains power supply is shut down. In this case, contact the local Service Agency.
If the light goes out, but water is still heating, usually the lamp is damaged.
