Note:
• The above inspection table sets the minimum period, and more frequent inspections are neces-
sary according to installation environment, operation condition / water quality condition.
• During the heat exchanger cleaning, you have to take off the parts such as pressure gauge or
lock the valve so that chemical solvent may not enter.
• During the cleaning, check the pipe connection parts in advance to prevent leakage of the chem-
ical solvent.
• Start the cleaning work after the chemical solvent and water are sufficiently mixed.
• It is better to perform the heat exchanger cleaning work in the early stage, and when the scale
accumulation becomes severe, it becomes difficult to remove them.
• In the region with poor water quality, periodical cleaning works are necessary.
• Chemical solvent has strong acidic property, so it shall be completely washed with water.
• To verify if the inside became clean, remove the hose and check inside the pipe.
• Make sure to perform the air purge to remove air inside water pipe.
• After the inspection, make sure to check if the heat source water properly flows before restart-
ing the product.
