The setting watertemperature can not over 40
0
(105 F)to assure the unit running safety.
Takecare!
An insulated pipefor protection must be used for

Installation items:
The factory only provides the main unit andthe water unit;the other itemsin the illustration
are necessary spareparts for thewater system ,thatprovided by usersor the installer.
Attention:
Please follow thesesteps when usingfor the firsttime
1.Open valve andcharge water.
2.Make sure thatthe pump andthe water-in pipehave been filledwith water.
3.Close the valveand start theunit.
ATTN: It is necessarythat the water-inpipe is higherthan the poolsurface.
The schematic diagram is forreference only. Please check the water inlet/outlet label on the
heat pump whileplumbing installation.

3.2 Swimming Pool Heat Pumps Location

3.INSTALLATION ANDCONNECTION
The unit willperform well inany outdoor locationprovided that thefollowing three factorsare
presented:
1. Fresh Air - 2. Electricity - 3. Pool filter piping
The unit maybe installed virtuallyanywhere outdoors. Forindoor pools pleaseconsult the
supplier. Unlikea gas heater, it has no draft or pilot light problem in a windy area.
DO NOT place the unitin an enclosedarea with alimited air volume,where the units
discharge air willbe re-circulated.
DO NOT place the unitto shrubs whichcan block airinlet. These locations deny theunit of a
continuous source offresh air whichreduces it efficiency and mayprevent adequate heat
delivery.
Normally, the pool heatpump is installedwithin 7.5 metresof the pool.The longer the
distance from thepool, the greaterthe heat lossfrom the piping.For the mostpart ,the piping
is buried. Therefore, the heatloss is minimalfor runs ofup to15 meters(15meters to andfrom
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.
3.3 How Close To Your Pool?

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 40mmNB PVC pipefor connection to
the pool orspa filtration piping.By using a50 NB to40NB you canplumb 50NB PVCpiping
Give serious considerationto adding aquick coupler fittingat the unitinlet and outletto 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 downthe fins intothe basepan and
drain out throughthe barbed plasticcondensation drain fittingon the sideof 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 thewater is condensationis to shut off the unit and keep the
pool pump running.If the waterstops running outof the basepan,it is condensation.AN
EVEN QUICKER WAYIS to TEST THE DRAIN WATER FOR CHLORINE- if theis no chlorine
present, then it'scondensation.
3.INSTALLATION AND CONNECTION

The Swimming PoolHeat Pumps exclusiverated flow titaniumheat exchanger requiresno
special plumbing arrangementsexcept bypass(please setthe flow rateaccording to the
nameplate). The water pressure dropis less than10kPa at max.Flow rate. Sincethere is no
residual heat orflame Temperatures, The unit does notneed copper heatsink piping. PVC
pipe can berun straight intothe unit.

PVC COUPLER
RECOMMENDED(Provided)

3.5 Swimming Pool Heat Pumps Electrical Wiring
NOTE: Althoughthe unit heatexchanger is electricallyisolated from therest of theunit, it
simply prevents theflow of electricityto or fromthe pool water. Grounding the unit is still
required to protectyou against shortcircuits inside theunit. Bonding isalso required.
3.INSTALLATION AND CONNECTION
3.6 Initial startup of the Unit
NOTE- In orderfor the unitto heat thepool 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 forwater leaks and verify flow to and from the pool.
2. Turnon the electricalpower supply tothe unit, then press the key ON/OFF of wire
controller, Itshould start in several seconds.
3. Afterrunning a fewminutes make surethe air leaving the top(side) of the unit is
cooler(Between 5-10 )
4. With theunit operating turnthe filter pumpoff. The unit should alsoturn off automatically,
5. Allowthe unit andpool pump torun 24 hours per day until desired pool water emperature is
reached. When thewater-in temperature reachsetting, The unit just shuts off. The unit will
now automatically restart(as long asyour pool pumpis running)when the pool temperature
drops more than2 below set temperature.
Time Delay- The unit is equipped with a 3 minute built-in solid staterestart delay includedto
protect control circuitcomponents and toeliminate restart cycling and contactor chatter.
This time delaywill automatically restartthe unit approximately 3 minutes after each control
circuit interruption. Evena brief powerinterruption will activate the solid state 3 minute
restart delay andprevent the unitfrom starting untilthe 5 minute countdown is completed.
Power interruptions duringthe delay periodwill have no effect on the 3 minute countdown.
8
The unit hasa separate molded-injunction box with a standard electrical conduit nipple
already in place.Just remove thescrews and thefront panel, feed your supply lines in
through the conduitnipple and wire-nutthe electric supply wires to the three connections
already in thejunction box (fourconnections if threephase). To complete electrical hookup,
connect Heat Pumpby electrical conduit,UF cable or other suitable means as specified (as
permitted by localelectrical authorities) toa dedicated AC power supply branch circuit
equipped with theproper circuit breaker, disconnect ortime delay fuse protection.
Disconnect -A disconnectmeans (circuit breaker , fused or un-fused switch) should be
located within sightof and readilyaccessible from the unit, This is common practice on
commercial and residentialair conditioners andheat pumps. It prevents remotely-energizing
unattended equipment andpermits turning off power at the unit while the unit is being
serviced.
