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.
3.1 Installation illustration
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.
3.INSTALLATION AND CONNECTION
The schematic diagram is for reference only. Please check the water inlet/outlet label on the
heat pump while plumbing installation.
The schematic diagram is for reference only. Please check the water inlet/outlet label on the
heat pump while plumbing installation.
The controller is mounted on the wall
IMPORTANT NOTE:
A WATER BY-PASS MUST BE PLUMBED TO REGULATE WATER FLOW TO HEAT PUMP.
FAILURE TO DO SO MAY RESULT IN POOR EFFICIENCY AND REDUCED HEATING OUTPUT.

10
3.INSTALLATION AND CONNECTION
The unit willperform well in any outdoor location provided that the following three factorsare
presented:
1. Fresh Air - 2. Electricity - 3. Pool filter piping
The unit maybe installed virtually anywhere outdoors. For indoor pools please consult the
supplier. Unlikea gas heater, it has no draft or pilot light problem in a windyarea.
DO NOT place the unitin an enclosed area with a limited air volume, where the units
discharge air willbe re-circulated.
DO NOT place the unitto shrubs which can block air inlet. These locations deny theunit of a
continuous source offresh air which reduces it efficiency and mayprevent adequate heat
delivery.
3.2 Swimming Pool Heat Pumps Location
Normally, the pool heatpump is installed within 7.5 metres of the pool. The longer the
distance from thepool, the greaterthe heat loss from the piping. For the most part ,the piping
is buried. Therefore, the heatloss is minimal for runs of up to15 meters(15 meters to andfrom
the pump =30 meters total),unless the ground is wet or the water table is high.A very rough
estimate of heatloss per 30 meters is 0.6 kW-hour,(2000BTU) for every 5 difference in
temperature between thepool water and the ground surrounding the pipe, which translates to
about 3% to5% increase in run time.

3.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 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.
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.

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.
IMPORTANT NOTE:
A WATER BY-PASS MUST BE PLUMBED TO REGULATE WATER FLOW TO HEAT PUMP.
FAILURE TO DO SO MAY RESULT IN POOR EFFICIENCY AND REDUCED HEATING OUTPUT.

3.5 Swimming Pool Heat Pumps Electrical Wiring
NOTE: Althoughthe unit heat exchanger is electrically isolated from the rest of the unit, it
simply prevents theflow of electricityto or from the pool water. Grounding the unit is still
required to protectyou against shortcircuits inside the unit. Bonding is also required.
3.INSTALLATION AND CONNECTION
3.6 Initial startup of the Unit
NOTE- In orderfor the unit to heat the pool or spa,the filter pump must be running to
circulate water throughthe heat exchanger.
Start up Procedure- After installation is completed, you should followthese steps:
1. Turnon your filter pump. Check for water leaks andverify flow to and from the pool.
2. Turnon the electrical power supply to the unit, thenpress the key ON/OFF of wire
controller, Itshould start in several seconds.
3. Afterrunning a few minutes make sure the air leavingthe top(side) of the unit is
cooler(Between 5-10 )
4. With theunit operating turn the filter pump off. The unit should also turn off automatically,
5. Allowthe unit and pool pump to run 24 hoursper day until desired pool water temperature
is reached. Whenthe water-in temperature reaches this setting, the unit willslow down for a
period of time,if the temperature is maintained for 45 minutes theunit will turn off. The unit
will now automaticallyrestart (as long as your pool pump is running)whenthe pool
temperature drops morethan 0.2 below set temperature.
Time Delay- The unit is equipped witha 3 minute built-in solid state restart delay includedto
protect control circuitcomponents and to eliminate restart cycling and contactor chatter.
This time delaywill automatically restart the unit approximately 3 minutes aftereach control
circuit interruption. Evena brief power interruption will activate the solid state3 minute
restart delay andprevent the unit from starting until the 5 minutecountdown is completed.
The unit hasa separate molded-in junction box with a standard electricalconduit nipple
already in place.Just remove the screws and the front panel, feedyour supply lines in
through the conduitnipple and wire-nut the electric supply wires to thethree connections
already in thejunction box (four connections if three phase). To complete electrical hookup,
connect Heat Pumpby electrical conduit, UF cable or other suitable meansas specified (as
permitted by localelectrical authorities) to a dedicated AC power supplybranch circuit
equipped with theproper circuit breaker, disconnect or time delay fuseprotection.
Disconnect -A disconnect means (circuit breaker , fused orun-fused switch) should be
located within sightof and readily accessible from the unit, This is common practice on
commercial and residentialair conditioners and heat pumps. It prevents remotely-energizing
unattended equipment andpermits turning off power at the unit while the unit is being
serviced.
