7. MAINTENANCE
Check the connection between power supply plug and socket
and ground wiring regularly;
In some cold area (below 0
℃
), if the system will be stopped for
a long time, all the water should be released in case of freezing
of inner tank and damage of E-heater.
It is recommended to clean the inner tank and E-heater every
half year to keep an efficient performance.
Check the anode rod every half year and change it, if it has
been used out. For more details, please contact the supplier or
the after-sale service.
It is recommended to set a lower temperature to decrease the
heat release, prevent scale and save energy if the outlet water
volume is sufficient.
Clean the air filter every month in case of any inefficiency on the
heating performance.
In terms of the filter set in air inlet directly (namely, air inlet
without connect with duct), the method of dismantle the filter is:
anti-clockwise unscrew the air inlet ring, take out the filter and
clean it completely, finally, remount it to the unit.
Before shutting the system off for a long time, please:
Shut off the power supply;
Release all the water in water tank and the pipeline and close
all the valves;
Check the inner components regularly.
