3. Installation and connection
3.1 Notes
1, We supply only the heat pump. All other components must be provided by the user or the installer.
2, Install a bypass if the water flow from the swimming pool pump is more than 20% greater than the allowable
flow through the heat exchanger of the heat pump.
3, Always place the heat pump on a solid foundation and use the included rubber mounts to avoid vibration and
noise.
4, Always hold the heat pump upright. If the unit has been held at an angle, wait at least 24 hours before starting
the heat pump.
3.2 Heat pump location
The unit will work properly in any desired location as long as the following three items are present:
1. Fresh air – 2. Electricity – 3. Swimming pool filters
The unit may be installed in virtually any outdoor location as long as the specified minimum distances to other
objects are maintained (see drawing below). Please consult your installer for installation with an indoor pool.
Installation in a windy location does not present any problem at all, unlike the situation with a gas heater (including
pilot flame problems).
ATTENTION: Never install the unit in a closed room with a limited air volume in which the air expelled from the unit
will be reused, or close to shrubbery that could block the air inlet. Such locations impair the continuous supply of
fresh air, resulting in reduced efficiency and possibly preventing sufficient heat output.
See the drawing below for minimum dimensions.
3.3 Distance from your swimming pool
The heat pump is normally installed within a perimeter area extending 7.5 m from the swimming pool. The greater
the distance from the pool, the greater the heat loss in the pipes. As the pipes are mostly underground, the heat
loss is low for distances up to 30 m (15 m from and to the pump; 30 m in total) unless the ground is wet or the
groundwater level is high. A rough estimate of the heat loss per 30 m is 0.6 kWh (2,000 BTU) for every 5 ºC
difference between the water temperature in the pool and the temperature of the soil surrounding the pipe. This
increases the operating time by 3% to 5%.
3.4 Check-valve installation
Note: If automatic dosing equipment for chlorine and acidity (pH) is used, it is essential to protect the heat pump
against excessively high chemical concentrations which may corrode the heat exchanger. For this reason, equipment
of this sort must always be fitted in the piping on the
downstream
side of the heat pump, and it is recommended to
install a check-valve to prevent reverse flow in the absence of water circulation.
