3.2 Swimming Pool Heat Pumps Location
The unit will perform well in any outdoor location provided that the following three factors are present -
1. Fresh Air — 2. Electricity — 3. Pool filter piping
The unit may be installed virtually anywhere outdoors. For indoor pools 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 close to shrubs which can block the air inlet. These locations
deny the unit of a continuous source of fresh air which reduces its efficiency and may prevent adequate heat delivery.
3.3 How Close To Your Pool?
Normally, the heat pump is installed within 7.5 metres of the pool. The longer the distance from the pool, the greater the
heat loss is from the piping. For the most part, the piping is buried. Therefore, the heat loss is minimal for runs of up to
15 metres (15 metres to and from the pump = 30 metres total), unless the ground is wet or the water table is high. A very
rough estimate of heat loss per 30 metres is 0.6 Kw-hour, (2000 BTU) for every 5˚C difference in temperature between
the pool water and the ground surrounding the pipe, which translates to about a 3% to 5% increase in run time.

3.4 Swimming Pool Heat Pumps Plumbing
Poolrite advises that a bypass valve setup, including 2 x 3 way valves be incorporated into the plumbing between the
inlet and outlet pipe work of the heat pump, for servicing requirement’s and winterizing of the heat pump.
PVC connections to the heat pump can either be 40mm or 50mm (class 9 or greater) depending on the requirement’s of
the plumbing provided.
Condensation:
Since the heat pump cools down the air by approximately 4 to 5°C the condenser will gather condensation. If the relative
humidity is very high this could be as much as several litres per hour. The water will run off the condenser into the base
pan and drain out through the drain hole fitting.
NOTE: Condensation can be mistaken for a water leak inside the unit.
A quick way to verify that the water is condensation, is to turn the heat pump off and keep the pump running. If the water
stops running out of the base pan then it is condensation. You could even check the drain water for chlorine. If there is no
chlorine present, then it is condensation.

3.5 Swimming Pool Heat Pump Electrical Wiring
NOTE: Electrical wiring and earthing should comply with local wiring rules, including a means of
isolating all active conductors with air gap contact separation.
3.6 Initial start up of the unit
NOTE: In order for the heat pump to operate, the water pump must be operating to circulate water
through the heat exchanger
Start up procedure – After installation is completed, you should follow these steps:
Caution: Ensure glued pipework is fully cured before running/starting the recirculation water pump.
1. Fully open the bypass valves ensuring that the bypass pipe is closed off
2. Prime the pump
3. Purge air from the heat exchanger by running the pump
4. Start the heat pump. For 3 phase units, the direction of rotation can be checked with a pressure switch error message
EE04 or the phase monitor will indicate “incorrect phase”
5. Adjust bypass flow so that the temperature out is 2 degrees Celsius more than the temperature in
6. After the heat pump has been running a few minutes check that the air leaving the heat pump is cooler than the
ambient temperature.
7. With the heat pump running, turn the water pump off. The heat pump will then go into standby mode after a few
seconds.
8. We recommend that the heat pump runs continually to achieve desired water temp (NOTE:THIS MAY TAKE SEVERAL
DAYS DEPENDING ON CLIMACTIC CONDITIONS AND EXPOSURE TO WEATHER) When the desired temperature is
reached the heat pump will go into standby mode until the temperature drops to 2 degrees below the set temperature
Water Flow Switch –Each heat pump is equipped with a flow switch that turns the unit on when the water pump is
running. The unit turns off automatically when the water pump is stopped
Time Delay – The heat pump software is programmed with a time delay to ensure that the heat exchanger is flooded
before the compressor starts

HEAT ON DEMAND WIRING CHANGES
For the 55kw & 62kw unit:
The flow switch from terminals 18 and 20 need’s to be placed into terminal’s
16 and 17. And the jumper wire from terminal’s 16 and 17 need’s to be placed into terminal’s 18 and 20.
NOTE: THIS SHOULD BE DONE ON THE TERMINAL STRIP: LOCATED ON THE RIGHT HAND SIDE
OF THE ELECTRICAL CONNECTION BOX
For all other unit’s: The flow switch from terminals 18 and 20 need’s to be placed into terminals 21
and 22. And the jumper wire from terminals 21 and 22 need’s to be placed into terminal’s 18 and 20
NOTE: THIS CHANGE IS MADE ON THE CHILLER 300 INPUT TERMINALS
NOTE
• Parameter 03:
0–30˚C means from (-30˚C) to (0˚C).
6˚C means (-6˚C)
• To enter parameters 02–09 both “ “ and “ “ must be pushed together for three seconds.
The controller will now unlock these parameters and will except required inputs.
Parameters 02–09 will auto–lock after ten seconds, provided no other buttons are pressed.
• When heat on demand is selected, the unit will operate the pump 10 minutes after the inlet
temperature falls below the set point. The compressor will not start unless the water sample
indicates that the pool water requires heating (or cooling). If heating or cooling is not
required, then the pump will stop after 1 minute.

5.1 Maintenance and Inspection
You should eliminate causes of prime loss and ensure unrestricted water flow. Clear debris from the pool/spa and pump
baskets regularly to avoid damage to the heat pump. Ensure the area around the heat pump is well ventilated and free
from debris and flooding. The evaporator/condenser should be well maintained at all times with no obstructions that will
affect the heat pumps performance.
WARNING: If debris such as leaves accumulate inside the unit, they could block the drain hole and cause corrosion to the
heat pump.
A refrigeration mechanic should be employed to do periodic maintenance to the heat pump, including cleaning the
condenser, checking gas levels and removing debris from inside the unit.
NOTE: Should the heat pump start working abnormally, switch it off and contact your authorized Poolrite technician.
If the heat pump is not to be used for an extended period of time then isolate power to the unit, and empty the heat
exchanger of water. This will avoid internal damage to the heat exchanger. It is advised to flush the heat exchanger with
non chlorinated fresh water or town water.
NOTE: The heat pump must be fully charged with water before power is restored, to avoid any damage to the unit.

•Is there sufficient water flow ?
•How long is the heat pump set to run for ?
•Are there any water features ?
•Does the pool have a blanket ?

5.4 Customer Responsibilities
BEFORE YOU CALL FOR SERVICE read the following points carefully which are your responsibility.
•A service charge will be made for service as a result of:
•Power not turned on or disrupted
•Heat pump not set to run for a long enough period
•Heat pump installed incorrectly
•Recirculation pump not operating correctly
•Controls incorrectly set
•Poor water chemistry (Salt Level, pH, etc)
•Poor water flow (Check filter is clean/Pump operation/Skimmer free of obstructions and bypass flow is not excessive)
•Heat pump being tampered with by unauthorized persons
• Excessive ambient conditions
