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.
