Installation items:
The factory only provides the main unit and the water unit; the other items in the illustration are
necessary spare parts for the water system ,that provided by users or the installer.
Attention:
Please follow these steps when using for the first time
1.Open valve and charge water.
2.Make sure that the pump and the water-in pipe have been filled 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.
The schematic diagram is for reference only. Please check the water inlet/outlet label on the heat
pump while plumbing installation.

3.2 Swimming Pool Heat Pumps 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 it efficiency and may prevent adequate heat delivery.

3.3 How Close To Your Pool?
Normally, the pool heat pump is installed within 7.5 metres 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 ℃difference in temperature between the pool water and the ground surrounding the
pipe, which translates to about 3% to 5% increase in run time.

3.4 Swimming Pool Heat Pumps Plumbing
The Swimming Pool Heat Pumps exclusive rated flow titanium heat exchanger requires no special
plumbing arrangements except bypass(please set the flow rate according to the nameplate). The water
pressure drop is less than 10kPa at max. Flow rate. Since there is no residual heat or flame Tempera-
tures, The unit does not need copper heat sink piping. PVC pipe can be run straight into the unit.
Location: Connect the unit in the pool pump discharge (return) line downstream of all filter and pool
pumps, and upstream of any chlorinators, ozonators or chemical pumps.
Standard model have slip glue fittings which accept 32mm or 50 mm PVC pipe for connection to the
pool or spa filtration piping. By using a 50 NB to 40NB you can plumb 40NB
Give serious consideration to adding a quick coupler fitting at the unit inlet and outlet to allow easy
draining of unit for winterizing and to provide easier access should servicing be required.

PVC COUPLER
RECOMMENDED(Provided)
From pump
CONDENSATION DRAIN
BARB FTG
Condensation: Since the Heat pump cools down the air about 4 -5℃, water may condense on the fins
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 fins into the basepan and drain out through the
barbed plastic condensation drain fitting on the side of the basepan. This fitting 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.
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 the is no chlorine present, then it's condensation.

3.INSTALLATIONAND CONNECTION
3.5 Swimming Pool Heat Pumps Electrical Wiring
NOTE: Although the unit heat exchanger is electrically isolated from the rest of the unit, it simply
prevents the flow of electricity to or from the pool water. Grounding the unit is still required to protect
you against short circuits inside the unit. Bonding is also required.
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 (four
connections if three phase). To complete electrical hookup, connect Heat Pump by electrical conduit,
UF cable or other suitable means as specified (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.
3.6 Initial startup of the Unit
NOTE- In order for the unit to heat the pool or spa, the filter pump must be running to circulate water
through the heat exchanger.
Start up Procedure - After installation is completed, you should follow these steps:
1. Turn on your filter pump. Check for water leaks and verify flow to and from the pool.
2. Turn on the electrical power supply to the unit, then press the key ON/OFF of wire controller, It
should start in several seconds.
3. After running a few minutes make sure the air leaving the top(side) of the unit is cooler(Between 5-10 ℃)
4. With the unit operating turn the filter 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 emperature is reached.
When the water-in temperature reach setting, The unit just shuts off. The unit will now automatically
restart (as long as your pool pump is running)when the pool temperature drops more than 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 5 minute countdown is completed. Power interruptions during the delay period will have no
effect on the 3 minute countdown.

5. Maintenance and inspection
Check the water supply device and the release often. You should avoid the condition of no water or
air entering into system, as this will influence unit's performance and reliability. You should clear the
pool/spa filter regularly to avoid damage to the unit as a result of the dirty of clogged filter.
The area around the unit should be dry, clean and well ventilated. Clean the side heating exchanger
regularly to maintain good heat exchange as conserve energy .
The operation pressure of the refrigerant system should only be serviced by a certified technician.
Check the power supply and cable connection often,.Should the unit begin to operate abnormally,
switch it off and contact the qualified technician.
Discharge all water in the water pump and water system ,so that freezing of the water in the pump or
water system does not occur. You should discharge the water at the bottom of water pump if the unit
will not be used for an extended period of time. You should check the unit thoroughly and fill the
system with water fully before using it for the first time after a prolonged period of no usage.
