1. Check the power supply plug and socket frequently to make sure that
they have good, reliable contact and are well grounded without overheat
phenomenon.
2. If the heater will not be used for a long time, especially in the regions
with low atmospheric temperature (lower than 0℃), in order to prevent
the heater to be damaged due to freeze of the water in the inner container,
the water inside the heater shall be drained away (refer to Item 9,
Cautions of this manual for the method to drain away the water inside the
inner container).
3. In order to ensure that the water heater can operate efficiently for long
term, it is recommended to clean periodically the inner container and
the deposits on the electrical heating components of the electric water
heater.
4. Suggest to examine the anode protection materials every half a year or
so. If all the materials have been consumed, please replace with the new
materials.
