1. INTRODUCTION
Inyourhandsyouholdprobablythemostadvancedandthemostefficientheatpumpcurrentlyavailableon
the market. This heat pump provides warm water in your pool at lowest possible cost. The heat pump is
manufacturedintightestaccordancewithrelatedstrictstandardsandnorms,inordertoprovidehighquality
operationandlong‐termreliability.
ThisInstallationandusermanualcontainsallthenecessaryinformationabouttheinstallation,operationand
maintenanceoftheheatpump.PleasereadthisInstallationandusermanualcarefullybeforeyoustarttouse
thisproduct.Themanufactureris notresponsiblefor any personalor propertydamage due to theimproper
installation,useormaintenancethatisnotinaccordancewiththisUserManual.
This Installation and user manual is an inseparable part of thisproduct;thereforeitmustbekeptingood
conditionandmustaccompanytheheatpump.
1.1 Productdescription
The heat pump is designed exclusively for swimming pool water heating or cooling and maintaining its
temperatureontherequestedlevel.Otherappropriateapplicationiswatertemperatureconditioningforfish
tanks, wine ciders or horse cooling facilities. These applications should be discussed with local installer or
distributor.Anyotherformofapplicationisconsideredinappropriate.
Theheatpumpachievesthehighestefficiencyat15÷35°Cairtemperature.Atambientairtemperatureslower
than‐5°Ctheefficiencyofthedevicedecreasesandatthetemperatureshigherthan+40°Ctheheatpumpcan
getoverheatedwhichmayresultinitsmalfunction,damageorfailure. Do not use the product out of the
designatedoperationalairtemperaturerangewhichisstatedinsection3.1Technicaldata.
Thisheatpumpisdesignedforswimmingpoolswithupto40m3‐HP1000andupto60m3‐HP1400ofpool
water volume. For proper operations there must be water flow through the exchanger of the heat pump
(withinwaterfiltrationcircuit)intherangeof4‐6m3/h.

The heat pump enables heat gain from the external air surrounding the swimming pool through the
compression–expansioncyclesoftheheat‐carryingliquid.Theairisdrivenbyafanthroughtheevaporator
whereit will deliverits heatto the heat‐carrying liquid(theairisbeingcooledatthesametime).Theheat‐
carryingliquidisthendeliveredtothespiralsoftheexchangerbythecompressorwhichpressurisesitandthus
heatsitup.Inthesespirals, theheat‐carryingliquiddeliversits heat to theswimmingpool water. Fromthe
exchangerthereisacooledliquidflowingtotheexpansionvalveorcapillarywhereitspressuredecreasesand
itgetscooleddownrapidlyatthesametime.Thiscooledliquidflowstotheevaporatoragainwhereitgets
heatedbytheflowingair.Thewholeprocessrunsfullyautomatically and is monitored by the pressure and
temperaturesensors.Thesameprincipleisappliedwhenheatpumpoperatesincoolingmode.
Usingsimplelanguage,aheatpumpisabletoextracttheheat/coldthatispresentinambientenvironmentand
leveragedpassitintothepoolwater.Whenheating,highertheambientairtemperatureis,morefreeenergy
cantheheatpumpextractandthusreachhigherefficiency.Atfavourableconditionsyoupayaround15%of
heat,i.e.85%ofheatisfree.Pleasereviewbelowdrawingofdifferentambientairconditionswithsubsequent
efficiencies.
Theheatpumpefficiencygrowsbytheincreasingsurroundingairtemperature.
Ittakessomedaystoachievetherequestedswimmingpoolwatertemperature.Thistimeperioddependson
heatlossandheatgainbalanceofyourpool.
Example factors of heat losses: poor pool construction, used materials, usage of cover, air –water
temperaturerelationship,freshwaterrefilling,filtration,etc.

Example factors of heat gains: intensity of sun, winds, orientation of pool, air – water temperature
relationship,etc.
Inordertoavoidheatlosswhentheswimmingpoolisnotbeingused,itishighlyadvisedtousepool’scover.
Idealwatertemperatureforexternalpoolsisconsideredatlevelsfrom27°to32°C.Thismaychangebasedon
particulardemandsoftheuser.Whensettingthedesiredairtemperaturehigherthan32°Cpleasereviewthe
materialcharacteristicsofyourpoolparts.Highwatertemperaturecandamagethesematerialsandcontribute
to creation of algea. Manufacturer, distributor and reseller do not bear responsibility resulting from
inappropriateheatpumpusage.

is forbidden to block or cover the intake or exhaust openings with clothes, towels,
buckets,canoes,trees,etc.Suchactionwouldleadtoadecreaseofneededairflow.That
wouldresultinheatpumpinefficiencyandunderperformance,eventuallytoheatpump
overeatwithsubsequentsecurityturningoff,malfunction,failureordamage.Especially
duringbloommonthsitishighlyadvisedtokeeptheevaporatorfinsclean.

 Donotleavethechildrenintheswimmingpool/attheswimmingpoolunattended.
 ThepositioningoftheheatpumpmustbeinaccordancewiththeSTN332000‐7‐702standard,i.e.
itmustbeplacedatleast3,5mfromtheswimmingpool´sexternalborder.
 For heating/cooling the swimming pool by the heat pump, the filtration pump must runand the
watermustflowthroughtheheatexchanger.
 Neverturnontheheatpumpifitiswithoutwaterandifthefiltrationdeviceisnotoperating.
 Protect the heat pump from freezing. Eliminate the water from the filtration and from the heat

 Manufacturerdoesnotbearany responsibilityconcenring damages causedbyinappropriateheat
pumpselection,installationorapplication.
 Donotpressurizethewaterheatexchangerhigherthan0.25MPa(2.5bar).Bypressureof0.5MPa
(5bar)thewaterheatexchangergetsirreversiblydamaged.Itisadvisedtoinstallasecurityvalve
withpressurethresholdat0.25MPa(2.5Bar)beforetheheatexchanger.
 Do not apply or use water of higher temperature than 45°C in water heat exchanger. Water
temperatureabove60°Cirreversiblydamagesthewaterheatexchanger.
 Manufacturerdoesnotbearany responsibilityconcerning damages causedbyinappropriateheat
pump performance and/or model selection, installation or application. Heat pump is considered
undersizedinthecaseitworksusuallyandinlong‐termmorethan18hoursdaily.Generalwarranty
voidappliesfordamagesonthedeviceorotherdamagesifthedeviceworksusuallyinlong‐term
morethan18hoursdaily.
 Theheatpumpmustbecorrectlysizedforitsapplication.
 Refrigerant connection between the water and the condensing unitmustcomplywithlocal
refrigerantregulations.Typically,therefrigerantcircuitmustbesealed.Manufacturerdoesnotbear
anyresponsibilityfordamagescausedbyincorrectrefrigerantworks.

3.2 Swimmingpoolwaterparameters
Theheatpumpisdesignedforheatingtheswimmingpoolwater.Althoughthewaterheatexchangerismade
fromthemostdurabletitanium,inordertoensurelongtermreliabilityoftheheatpumpthepoolwatermust
beinaccordancewiththerelatedsanitaryrequirements.
Thelimitvaluesfortheheatpumpoperationarethefollowing:
- pHvaluerangingfrom6.8to7.9,
- totalchlorineamountnotexceeding3mg/l,
- saltcontent6%wt/wt.
ShouldyouhavedifferentvaluesofpH,chlorineorsaltpleasetrytoapplyappropriateagentsorcontactyour
swimming pool builder to resolve the situation. Above mentioned values are recommended for pools in
general.
Itisalsoadvisedtokeepthewaterhardnessonthelowerlimitoftheoptimalrange,i.e.closelyabove8°N.
