6.1 Control of Water Quality

The circulating fluid used in this unit is fresh water (tap water). This unit may be damaged when unpermitted fluids are used.

Potential fluid leak may occur if disregarded, which results in electric shock and ground fault.

ONLY use fresh water (tap water) which satisfies water quality standards as shown in the table below.

If the periodic inspection finds a nonconforming substance in the facility water, wash the tank and the cirulating circuit, and replace the water in the tank. Water will evaporate, and impurities will build up. Even if no abnormal event occurs, it is recommended to replace the water in the tank once every three months. Refer to section "6.2 Inspection and Cleaning" for the periodic inspection.
