Installation of Indoor Unit
Sanitary Water Tank and Sanitary Water Tank Kit /
Solar Thermal Kit
Installing sanitary water tank requires following considerations :
• Sanitary water tank should be located at the flat place.
• Water quality should be complied with EN 98/83 EC Directives.
• As this water tank is sanitary water tank (indirect heat exchange), do not use anti water-freezing
treatment like ethylene grycol.
• It is highly recommend to wash out inside of the sanitary water tank after installation. It ensures
generating clean hot water.
• Near the sanitary water tank there should be water supply and water drain to easy access and
maintenance.
• Set the maximum value of the temperature control device of sanitary tank.
While installing sanitary water tank with sanitary water tank kit or solar thermal kit, there are some
constraints like below :
• Sanitary water tank should be located under the indoor unit or same height with the indoor unit.
• Sanitary water tank should be located under the solar thermal system.
• Distance between sanitary water tank sensor or solar thermal sensor should be less than 5 m.
• If there is AC power cable near the sensor cable, the sensor cable should be away from the AC
power cable at least 5 m to prevent electric noise.
