3. Installation and Connection
3.1 Installation Illustration
Attention:
Please follow these steps when using for the rst time
1.Open valve and charge water.
2.Make sure that the pump and the water-in pipe have been lled with water.
3.Close the valve and start the unit.
ATTN: It is necessary that the water-in pipe is higher than the pool surface.
Put the heat pump on a at, solid base. Tilting the heat pump for max 3° is allowed.
Install silent blocks in order to avoid vibrations and noise.
All feeding of water treatment to the pool water has to be done downstream of the heat pump.
It is normal for condens water to come out of the heat pump. This is not a leak or fault with the
unit. If the humidity is very high, the condens water could be a number of liters a day.
Always keep the heat pump in upright position. If the unit has been tilted, then wait 24h before
starting the heat pump.
It is recommended to install a by-pass for easy maintenance.

10
The unit may be installed virtually anywhere outdoors. For indoor pools please consult the
supplier. 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 next to shrubs which can block air inlet. These locations prevent the unit of
having a continuous source of fresh air which reduces its efciency and may prevent adequate heat
delivery.
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
after long term use. 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 backow when there is no water circulation.
Damage to the heat pump caused by disregarding any of these recommendations will invalidate
the warranty.
The heat pump should be located maximum 7,5m away from the swimming pool. The longer the
distance from the pool, the greater the heat loss from the piping. For longer distances it is highly
recommended to insulate the piping to avoid excessive heat loss.
3.2 Swimming Pool Heat Pump Location
3.3 How Close To Your Pool?

ENG
It is recommended to install a by-pass for easy maintenance.
All feeding of water treatment to the pool water has to be done downstream of the heat pump.
Give serious consideration to adding a quick coupler tting at the unit inlet and outlet to allow easy
draining of unit for winterizing and to provide easier access should servicing be required.
Condensation: Since the Heat pump cools down the air about 4 -5°C, water may condense on the
ns of the horseshoe shaped evaporator. If the relative humidity is very high, this could be as much
as several litres an hour. The water will run down the ns into the basepan and drain out through
the barbed plastic condensation drain tting on the side of the basepan. This tting is designed to
accept 20mm clear vinyl tubing which can be pushed on by hand and run to a suitable drain. It is
easy to mistake the condensation for a water leak inside the unit.
3.4 Swimming Pool Heat Pump Plumbing
NB: A quick way to verify that the water is condensation is to shut off the unit and keep the
pool pump running. If the water stops running out of the basepan, it is condensation. AN EVEN
QUICKER WAY IS to TEST THE DRAIN WATER FOR CHLORINE - if there is no chlorine
present, then it’s condensation.

12
Check if the electrical mains voltage corresponds with the operating voltage of the heat pump
prior to hooking up the unit. It is recommended to use a separate fuse as well as adequate wiring.
The unit has a separate molded-in junction box with a standard electrical conduit nipple already in
place. Just remove the screws and the front panel, feed your supply lines in through the conduit
nipple and wire-nut the electric supply wires to the three connections already in the junction box.
To complete electrical hookup, connect Heat Pump by electrical conduit, UF cable or other suitable
means as specied (as permitted by local electrical authorities) to a dedicated AC power supply
branch circuit equipped with the proper circuit breaker, disconnect or time delay fuse protection.
Disconnect - A disconnect means (circuit breaker , fused or un-fused switch) should be located
within sight of and readily accessible from the unit, This is common practice on commercial and
residential air conditioners and heat pumps. It prevents remotely-energizing unattended equipment
and permits turning off power at the unit while the unit is being serviced.
Start up Procedure - After installation is completed, you should follow these steps:
1. Turn on your lter pump. Check for water leaks and verify ow to and from the pool.
2. Turn on the electrical power supply to the unit, then press the key ON/OFF on the wire controller,
It should start in several seconds.
3. After running a few minutes make sure the air leaving the side of the unit is cooler.
4. With the unit operating turn the lter pump off. The unit should also turn off automatically,
5. Allow the unit and pool pump to run 24 hours per day until desired pool water temperature is
reached. When the water-in temperature reaches this setting, the unit will slow down for a period
of time, if the temperature is maintained for 45 minutes the unit will turn off. The unit will now
automatically restart (as long as your pool pump is running)when the pool temperature drops more
than 0.2 below set temperature.
Time Delay- The unit is equipped with a 3 minute built-in solid state restart delay included to protect
control circuit components and to eliminate restart cycling and contactor chatter. This time delay will
automatically restart the unit approximately 3 minutes after each control circuit interruption. Even a
brief power interruption will activate the solid state 3 minute restart delay and prevent the unit from
starting until the 3 minute countdown is completed.
3.5 Swimming Pool Heat Pumps Electrical Wiring
3.6 Initial Start-up of the Unit
NOTE: Although the heat pump is electrically isolated from the rest of the pool equipment, this
only prevents the passage of electricity to or from the pool water. Grounding the unit is still
required to protect yourself from short circuits inside the unit. Provide an adequate ground
connection.
NOTE: In order for the unit to heat the pool or spa, the lter pump must be running to
circulate water through the heat exchanger.
