11.6 Maintenance/Repair checklist
(
̻
: Check mark)
CAUTION
• The above checklist is set based on the minimum period and more frequent checking can be required depending
on the operating 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 becomes difficult after the scaling has
accumulated.
• In areas where the water quality is poor, cleaning is required periodically.
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.
