Cleaning

External cleaning
Power must be switched off before cleaning the water heater.
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.
Internal cleaning
2
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.
Check
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.
