OPERATING INSTRUCTIONS
Warning: Always ensure that the heater tank is fully filled with water
(especially after installation, servicing/repairs or interruptions
of water supply) before switching on the electrical supply.
a. Switch on the heater switch. The
‘POWER’ (Green)
and
‘HEATING’ (Red)
will light up, indicating that the heating element is heating up the water.
b. Adjust the temperature knob clockwise for higher temperature and anti-
clockwise for lower temperature. When the water temperature reaches
approximately
70 degree celsius
, the
‘HEATING’ (Red)
will no longer
light up, indicating that the Automatic Temperature Control System has
switched off the heating element.
c. The water heater needs to be turned on for a certain period of time to
reach to the acceptable temperature. For more detailed information,
please refer to the table about Heating Time on Page 5.
d. It is good practice to switch off the heater switch when the heater is not
in use for long periods of time.
During the heating process, it is normal to see water dripping at the safety
valve.
Do not
cover up the safety valve outlet hole. The safety valve is to be
operated regularly (preferably at least once every six months) to remove lime
deposit and ensure no blockage.

MAINTENANCE
Over a long period of use, the internal parts of the heater tank that are in
contact with hot water have a tendency to accummulate lime scale. To ensure
proper functioning of the heater, it is important that the lime scale be removed
from the Heating Element & Pressure Relief Valve. It is also recommended to
check the depletion of the Anti-corrosion Anode Rod periodically.
The power of the heater needs to be switched off for the tank to cool down.
Users should be careful when handling drained water that can be hot and
cause scalding.
To discharge the water completely from the tank, remove the safety valve
from the water heater.
Note : It is recommended that periodic maintenance be carried out at
least once a year by qualified personnel.
