Attention:
Please follow thesesteps when usingfor the firsttime
1.Open valve and charge water.
2.Make sure thatthe pump andthe water-in pipehave been filledwith water.
3.Close the valve and start the unit.
ATTN: lt is necessarythat the water-inpipe is higherthan the poolsurface.

3.2 Swimming Pool Heat Pumps Location
The unit willperform well inany outdoor locationprovided that thofollowlng threo 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 hasno.draft orpilot light problemin a windyarea.
DO NOTplace the unitin an enclosedarea with alimited air volume,where the uniis

DO NOTplscs th6 unltto shrubs whlchcan block airinlet. These locations deny theunit of a

estimate of heat loss per 30 meters is 0.6 kW-hour,(2000BTU)for every 5 C 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
The Swimming PoolHeat Pumps exclusive rated flow titanium heat exchanger requires no
special plumbing arrangementsexcept bypass(please setthe flow rateaccording to the
nameplate). The water pressure drop is less than 10kPa 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.
Location: Connect the unit in the pool pump discharge (return) line downstream of all filter
and pool pumps,and upstream ofany chlorinators, ozonatorsor chemical pumps.
Standard model haveslip glue fittingswhich accept 32mmor 50 mm PVC pipe for
connection to thepool or spafiltration piping. Byusing a 50NB to 40NByou can plumb40NB
Give serious considerationto adding aquick coupler fittingat the unitinlet and outletto allow

CONDENSATION
DRAIN
BARB FTG
Condensation: Since theHeat pump coolsdown the airabout 4 -5C, water maycondense on
the fins ofthe horseshoe shapedevaporator. lf the relative humidityis very high,this could
be as muchas several litresan hour.The waterwill run downthe fins inioihe basepan and
drain out throughthe barbed plasticcondensation drain fittingon the sideof the basepan.
This fitting ls designed to accept 20mm clear vinyltubing which can be pushed on by hand
and run toa suitable drain.lt is easyto mistake thecondensation for awater leak insidethe
unit.
NB: Aquick way toverify that thewater is condensation is to shutoff the unit and keepthe
pool pump running.lf the waterstops running outof the basepan, it is condensation.AN
EVEN QUICKER WAYIS toTEST THEDRAIN WATER FOR CHLORINE. if theis no chlorine
present, then it's condensation.

3.6 lnitial start-up of the Unit
NOTE- ln orderfor the unitto heat thepool or spa,the filter pumpmust be runningto
circulate water throughthe heat exchanger.
Start up Procedure- Afterinstallation is completed,you should followthese steps:
1. Turn on your filterpump. Check forwater leaks and verify flow toand from the pool.
2, Turn on the electricalpower supply lo the unit, then press the key ON/OFF of wire
controller, ltshould start in several seconds.
3. Afterrunning a fewminutes make surethe air leavingthe top(side) ofthe unit is
cooler(Between 5-"1 0 C)
4. Wlth thounlt oparatlng turnthe filter pumpoff. Theunit should alsoturn off automatically,
5. Allowtho unlt andpool pump torun 24 hoursper day untildesired pool watertemperature
lg roached, Whon tho water-ln temperature reaches this setting, the unit willslow down fora
porlod of tlmo,lf tho tomperature ls maintained for45 minutes the unit will turn off. The unit
wlll now outomatlcallyrestart (as longas your pool pump is running)whenthe pool
lemperature drops more than 0.2 below set temperature.
Time Delay- The unit is equipped with a 3 minute built-in solid state restart delay included to
protoct control circuitcomponents and toeliminate restart cyclingand contactor chatter.
This time delaywill automatically restartthe unit approximately3 minutes aftereach control
circuit interruption. Evena brief powerinterruption will activatethe solid state3 minute
restart delay and prevent the unitfrom starting untilthe 5 minutecountdown is completed.

5. MAINTENANCE AND INSPECTION
66Check the watersupply device andthe release often.Youshould avoid thecondition of no
water or airentering into system,as this willinfluence unit's performanceand reliability.
Youshould clear thepool/spa filter regularly to avoid damageto the unitas a resultof the
dirty of clogged filter.
&The area aroundthe unit shouldbe dry, clean andwell ventilated, Cleanthe side heating
exchanger regularly tomaintain good heatexchange as conserveenergy .
&The operation pressureof the refrigerantsysiem should onlybe serviced bya certified
technician.
6pCheck the powersupply and cableconnection often,.Should theunit begin tooperate
abnormally, switch lt of and contactthe qualified technician.
6Discharge all waterin the waterpump and watersystem ,so that freezing of thewater in the
pump or watersystem does notoccur. Youshould discharge thewaier at thebottom of
water pump ifthe unit willnot be usedfor an extendedperiod of time.Youshould check the
unitthoroughly andfill thesystemwithwaterfullybeforeusingitforthefirsttimeaftera
prolonged period ofno usage.
@Checks to thearea
Prior to beginningwork on systemscontaining flammable refrigerants, safety checks are
necessary to ensurethat the riskof ignition isminimised. For repairto the refrigerating
system, the followingprecautions shall becomplied with priorto conducting workon the
system.
&Work procedure
Work shallbe undertaken undera controlled procedureso as tominimise the riskof a
flammable gas orvapour being presentwhile the workis being performed.
@ General work area
All maintenance staff and othersworking in thelocal area shallbe instructed onthe nature
of work beingcarried out. Work in confinedspaces shall beavoided. Thearea around the
workspace shall besectioned off. Ensure that theconditions within thearea have been
made safe bycontrol of flammablematerial.
@Checking for presenceof refrigerant
The area shallbe checked withan appropriate refrigerantdetector prior toand during work,
to ensure thetechnician is aware of potentially flammable atmospheres. Ensure thatthe
leak detection equipmentbeing used issuitable for usewith flammable refrigerants, i.e.
non-sparking, adequately sealed or intrinsically safe.
6 Presence of fire extinguisher
lf any hotwork is tobe conducted onthe refrigeratlon equipmentor any associatedparts,
appropriate fire extinguishingequipment shall beavailable to hand. Have a drypowder or
C02 fire extinguisheradjacent to thecharging area.
