According to the local water quality and user behaviors, descale the tank
regularly (typically every month). Cleaning of heating tube and replacement of
magnesium anode vary with the water quality. Normally, the frequency increases
with the water hardness. It must be operated by professionals.
This water heater is manufactured to suit the water conditions of most public
reticulated water supplies. The content of dissolved solids (TDS) in water ranged
from 100 mg /L to 600mg /L. However, there are some known water chemistries
which can have detrimental effects on the water heater and its operation and / or life
expectancy. If you are unsure of your water chemistry, you may be able to obtain
information from your local water supply authority.
If the TDS content in water is more than 600mg /L or softening water is used, the
consumption of magnesium anode may be faster. Please shorten the inspection
interval period of magnesium anode and replace the consumed magnesium anode
in time.
