8.1 Checking the anodes & replacing if required
(Frequency: Every Five Years - Replace if required)
The anode protects the inner lining of your hot water tank. When
the anode become degraded the level of protection is diminished.
It is recommended that anode is periodically checked for its level
of degradation and gets replaced if required.
• Turn off the power, and turn off the cold water inlet valve.
• Open a hot water tap, and decrease the pressure of the inner
container.
• Open the drain port, and release the water until no more water
flows out.
• Locate the anode positions on the left hand side.
• Remove the anode cover for the middle anode by releasing
the screws.
• Unscrew the anode and pull directly away from the tank
• Check for degradation.
• If still in suitable condition, refit ensuring an effective seal.
• If anode is in an unsuitable condition, replace with a new
one, ensuring an effective seal.
• Re open the cold water inlet valve.
• Open a hot water tap until hot water flows out, then turn off
the hot water tap.
• Turn on the power to restart the unit.
• Now the unit can be used as normal.
8.2 Cleaning the inner tank and E-Heater
(Frequency: Every Five Years)
It is recommended to clean the inner tank and E-Heater regularly
to maintain efficient performance.
• Turn off the power.
• Close the cold water inlet valve & open a hot water tap.
• Use a flexible pipe to connect the drain port to a suitable
sewage drain. (Note: The min. heat resistance of the drain
pipe must not be less than 93°, if the drain pipe does not
meet the requirement, please open the cold water inlet
valve & open a hot water tap, until the temperature of the
water is suitable for the drain pipe).
• Open the drain port of the water heater; drain out all the
water in the inner tank. If it is needed, use water to wash
the inner tank several times to clear the deposits.
• Close the drain port, re-fill the inner tank with water, and
turn the power back on.
8.3 Operating the PTR valve
(Frequency: Every Half Year - Replace if required)
It is recommended to operate the PTR valve periodically to ensure
water flows freely. If water doesn't flow freely, the PTR valve will
need to be replaced.
• Locate the PTR valve on the left hand side of the unit.
• Carefully release the valve using the lever & release some
water from the tank.
NOTE: Water expelled may be extremely hot.
• If water flows freely the PTR appears to still be in a suitable
working condition.
• If water does not flow freely it would appear the PTR valve is
due for replacement.
• If the PTR valve needs replacing, please contact your plumber
or our service team for further assistance.
8.4 Other maintenance checks
1. Regularly check the electrical wiring for any damage and
contact our service team or your electrician if damage is
evident.
2. In some cold areas (below 0°), if the system will be stopped
for a long time, all the water in the tank should be released
and the tank refilled prior to reuse in case freezing has
occurred inside the inner tank. Failure to do this may result in
severe damage to the heating element.
