Air-to-Water Heat Pump
DHW Tank and DHW Tank Kit / Solar Thermal Kit
Installing DHW tank requires following considerations :
• DHW tank should be located at the flat place.
• Water quality should be complied with EN 98/83 EC Directives.
• As this water tank is DHW tank (indirect heat exchange), do not use anti water-freezing treatment
like ethylene grycol.
• It is highly recommend to wash out inside of the DHW tank after installation. It ensures generating
clean hot water.
• Near the DHW tank there should be water supply and water drain to easy access and maintenance.
• Set the maximum value of the temperature control device of DHW tank.
While installing DHW tank with DHW tank kit or solar thermal kit, there are some constraints like
below :
• DHW tank should be located under the indoor unit or same height with the indoor unit.
• DHW tank should be located under the solar thermal system.
• Distance between DHw 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.
