The unit willperform well inany outdoor locationprovided that thefollowing three factors are
presented:
1. Fresh Air - 2. Electricity - 3. Pool filter piping
The unit maybe installed virtuallyanywhere outdoors. Forindoor pools please consult the
supplier. Unlikea 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 willbe re-circulated.
DO NOT place the unit to shrubs which can block air inlet. These locations deny the unit of a
continuous source offresh air whichreduces it efficiency and mayprevent 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 thepool, the greaterthe heat lossfrom 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 groundis wet orthe water tableis high.A veryrough
estimate of heatloss per 30meters is 0.6kW-hour,(2000BTU) for every 5 difference in
temperature between thepool water andthe ground surroundingthe pipe, whichtranslates to
about 3% to5% increase inrun time.

3.4 Swimming Pool Heat Pumps Plumbing
Location: Connect theunit in thepool pump discharge(return) line downstreamof all filter
and pool pumps,and upstream ofany chlorinators, ozonatorsor chemical pumps.
Standard model haveslip glue fittingswhich accept 32mmor 50 mmPVC pipe for
connection to thepool or spafiltration piping. Byusing a 50NB to 40NByou can plumb40NB
Give serious considerationto adding aquick coupler fittingat the unit inlet and outlet to allow
easy draining ofunit for winterizingand to provideeasier access shouldservicing be
required.
Condensation: Since theHeat pump coolsdown the airabout 4 -5 , water maycondense on
the fins ofthe horseshoe shapedevaporator. Ifthe relative humidityis very high, this could
be as muchas several litresan hour.The water will run down the fins into the basepan and
drain out throughthe barbed plasticcondensation drain fittingon the side of the basepan.
This fitting isdesigned to accept20mm clear vinyltubing which canbe pushed onby hand
and run toa suitable drain.It is easyto mistake thecondensation for awater leak insidethe
unit.
NB: Aquick way toverify that the water is condensation is to shut off the unit and keep the
pool pump running.If the waterstops running outof 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'scondensation.

nameplate). The water pressure drop is less than 10kPa at max. Flow rate. Since there is no
residual heat orflame Temperatures, The unit does not need copper heat sink piping. PVC

3.5 Swimming Pool Heat Pumps Electrical Wiring
NOTE: Althoughthe unit heatexchanger is electricallyisolated from therest 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 theunit. Bonding is also required.
3.INSTALLATION AND CONNECTION
3.6 Initial startup of the Unit
NOTE- In orderfor the unitto heat the pool or spa, the filter pump must be running to
circulate water throughthe heat exchanger.
Start up Procedure- Afterinstallation is completed, you should follow these steps:
1. Turnon your filterpump. Check for water leaks and verify flow to and from the pool.
2. Turnon the electricalpower supply to the unit, then press the key ON/OFF of wire
controller, Itshould start in several seconds.
3. Afterrunning a fewminutes make sure the air leaving the 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 andpool pump to run 24 hours per day until desired pool water emperature is
reached. When thewater-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 than2 below set temperature.
Time Delay- The unit is equipped with a 3 minute built-in solid state restart delay included to
protect control circuitcomponents and to eliminate restart cycling and contactor chatter.
This time delaywill automatically restart the unit approximately 3 minutes after each control
circuit interruption. Evena brief power interruption will activate the solid state 3 minute
restart delay andprevent the unit from starting until the 5 minute countdown is completed.
Power interruptions duringthe delay period will have no effect on the 3 minute countdown.
7
The unit hasa 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 conduitnipple and wire-nut the electric supply wires to the three connections
already in thejunction box (four connections if three phase). To complete electrical hookup,
connect Heat Pumpby electrical conduit, UF cable or other suitable means as specified (as
permitted by localelectrical authorities) to a dedicated AC power supply branch circuit
equipped with theproper circuit breaker, disconnect or time delay fuse protection.
Disconnect -A disconnect means (circuit breaker , fused or un-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.
