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.

(or other type filter)
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 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.
3.2 Swimming Pool Heat Pumps Location
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

Installation and Connection
3.4 Swimming Pool Heat Pumps Plumbing
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 40mm NB PVC pipe for connection to
the pool or Swimming Pool filtration piping. By using a 50 NB to 40NB you can plumb 50NB
PVC piping straight into the unit.
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.
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 3/4" 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.INSTALLATION AND CONNECTION
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 Temperatures, The unit does not need copper heat sink piping. PVC
pipe can be run straight into the unit.

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.
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.
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.
