Check the connection between power supply plug and socket, and ground wiring regularly.
In some cold sites (below 0°C), if the system will be stopped for a long time, all the water should be
released for preventing the risk of freezing of inner tank and damages to e-heater.
It is recommended to clean the inner tank and e-heater regularly to keep an efficient performance.
Check the anode rod every half year and change it if it is necessary. For more details, please contact Authorized
Technical Service.
It is recommended to set a lower temperature to decrease the heat release, prevent scale and save energy
if the outlet water is sufficient.
Clean the air filter every month in order to avoid decrease in heating performance and malfunctions.
•
If air filter has been set in air inlet directly (namely, air inlet without connection with canvas), the method of
dismantle the filter is the following: anti-clockwise the air inlet ring, take out the filter and clean it completely,
and finally remount it to the Unit.
Before shutting the system down for a long time, please:
•
Shut down the power supply;
•
Release all the water in water tank and the pipeline and close all the valves;
•
Check the inner components regularly.
•
Turn off the power, and turn off the water inlet valve.
•
Open hot water tap, and decrease the pressure of the inner container.
•
Open the temperature pressure valve, and drain out the water, until there is no water flowing out.
•
Get off the anode rod according to instructions.
•
Replace the anode rod with a new one, and make sure it is effectively sealed.
•
Open cold water valve until hot water flows out, and turn off the hot water tap.
