The water heater must be repaired or maintained by qualified
professionals. Improper methods may cause serious injury or damage to
property.
Take a wet cloth and dab it with small quantity of neutral detergent.
Lightly wipe the water heater. Do not use petrol or other solvents.
Finally use a dry cloth to wipe; make use to dry the water heater
thoroughly. Make sure not to use detergents containing abrasive agents
(e.g. toothpaste), acidic substances, chemical solvents (e.g. alcohol) or
polish to clean the water heater.
In order to ensure that the water heater will work with high efficiency,
clean the heating tube and inner chamber once every two years. Take
care not to damage the exterior of the heating pipe and the protective
layer on the surface of the inner chamber.
Depending on the local water quality and usage habit, the Anode rod
should be regularly replaced. If maintenance is required, please contact
the local Maintenance Department.
When the water heater is in use, the safety valve should be checked once
every month. To check it, turn the safety valve's small handle on the side of
the water intake (take care not to hurt your hand). If there is water flowing
out, the safety valve is working normally. Please contact the local
After-sales Department if no water flows out. In the event of damage to the
safety valve, please replace it with a safety valve of similar specifications.
Regularly engage service personnel to carry out safety inspection and
promptly clear the water heating pipes of the scale. Check also the
consumption of the Anode rod; change it if consumption becomes
excessive.
