! CAUTION
• The above checklist is set based on the minimum period and
more frequent checking can be required depending on the oper-
ating condition/water quality condition.
• When cleaning the heat exchanger, make sure to take parts out
or lock the value so that chemical detergent does not penetrate
into the pressure gauge etc.
• When cleaning the heat exchanger, check the connecting part of
the water pipes prior to cleaning so that the chemical detergent
does not leak.
• After sufficiently mixing the chemical detergent with water, start
cleaning.
• Cleaning the heat exchanger is easier at the initial stage and be-
comes difficult after the scaling has accumulated.
• In areas where the water quality is poor, cleaning is required pe-
riodically.
Because chemical detergent has strong acidity, it must be
washed off thoroughly with water.
• To check whether it is cleaned well inside, remove the hose and
check the inside.
• Purge the air to remove any air inside the water pipe.
• After checking, always check whether the heat water supply is
flowing normally flowing before operating the product.
