2.2 Not suitable for Pools and Spas
Note, this heat pump is not suitable for pool or spa heating due to the high levels of salt
and/or chlorine used and volume of water to be heated. If used for such applications,
your warranty will be void.
2.3 Heat Pump Positioning
The heat pump extracts heat from the air being drawn through the fin coils of the
evaporator. This produces cold outlet air as a by-product. In order for the heat pump to
operate efficiently, good ventilation is required to extract the heat from the air easily and
therefore the heat pump is best located outside.
The R134a refrigerant used has a boiling point of minus 26 deg C so there is no risk of
damage to the heat pump from frost. Performance may be reduced in very low
temperatures but the system will not be damaged by such climatic conditions.
The cold exhaust air should not be allowed to feed back into the inlet or operational efficiency
will be reduced. The heat pump should not facing into a prevailing wind. However, alternate
locations may be used such as a large double garage (minimum of 120 cubic metres).
Note: For water pipe connection instructions, refer section 2.5 below.
