3. Installation and Connection
3.1 Heat Pump Location
The unit will perform well in any outdoor location provided that the following three factors are
presented:
1. Fresh Air - 2. Electricity - 3. Pool filter piping
The unit may be installed virtually anywhere outdoors. For indoor pools please consult the
supplier. Unlike a gas heater, it has no draft or pilot light problem in a windy area.
DO NOT place the unit in an enclosed area with a limited air volume, where the units
discharge air will be re-circulated.
DO NOT place the unit to shrubs which can block air inlet. These locations deny the unit of a
continuous source of fresh air which reduces its efficiency and may prevent adequate heat
delivery.
3.2 How Close To Your Pool?
Normally, the pool heat pump is installed within 7.5 meters of the pool. The longer the distance
from the pool, the greater the heat loss from the piping. For the most part, the piping is buried.
Therefore, the heat loss is minimal for runs of up to15 meters(15 meters to and from the pump =
30 meters total), unless the ground is wet or the water table is high. A very rough estimate of heat
loss per 30 meters is 0.6 kW-hour,(2000BTU) for every 5°C difference in temperature between the
pool water and the ground surrounding the pipe, which translates to about 3% to 5% increase in
run time.

3.3 Installation illustration
Remarks:
The factory only provides the heat pump. Other parts, including a contingent by-pass are to be
provided by the user or installer.
Attention:
Please take the following steps when installing the heat pump:
1. Each addition of chemicals has to be performed through the conduits located AFTER the heat pump.
2. Install a by-pass for easy maintenance
3. Always place the heat pump on a solid base and use the supplied silent blocks in order to avoid
vibrations and noise.
4. Always keep the heat pump in upright position. If the unit has been tilted, you should wait for at least
24 hours before turning it on.
3.4 Installation of a check valve
When using automatic chlorine and pH dosage systems, it is of uttermost importance to protect
the heat pump from high concentrations of these chemicals that could corrode the heat exchanger
Therefore, such systems should add the chemicals in the conduits located DOWNSTREAM of the
heat pump and it is recommended to install a check-valve in order to prevent backflow when there
is no water circulation.
Damage to the heat pump caused by disregarding any of these recommendations will invalidate
the warranty.
