Check the power supply plug and socket frequently to make sure that they have good, reliable
contact and are well grounded without overheating phenomenon.
If the heater is not used for a long time, especially in the regions with low atmospheric tempera-
ture(lower than 0℃), the water inside the heater shall be drained away. This will prevent the
damage to the heater due to water freezing in the inner container, (Refer Cautions in this
manual for the method to drain away the water from the inner container).
In order to ensure that the water heater operates efficiently for a long time, it is recommended
to clean the inner container and the deposits on the electrical heating components periodically.
It is recommended to examine the magnesium anode protection materials every six months or
so. If all the material has been consumed, please replace with the new material.
