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.
