E. Warranty ServiceBefore calling for warranty service you should check the following:1. Clean all filters and traps in the pool circulation system. Low water flow will cause the unit
toshutdownorcycle.2. Check and adjust all water flow valves and adjust to the proper positions to insure proper water
flow through the heater.3.Checkthewaterpumptimersettingtoinsurethereisenoughtimeallottedforaproperheating
cycle.4. Check all circuit breakers and disconnects. Note: More than one disconnect may be required
toshutofforturnonpowertotheheater.5. Confirm that all heater controls, thermostat, thermostat selector switch, reset tripper, and
optional auto heat switch (if so equipped), are in the correct position.6.Ifany3rdpartycontroldevicesareinstalledonthepool/spasystemmakesuretheyarefunction-

REQUIRED TO ELIMINATE ALL POWER TO THIS UNIT
WARNING
A swimming pool & spa heatpumputilizesprovenrefrigeranttechnology to capture the heatin the outside air and transfersittothepoolwater.Refrigerantisusedbecauseof itsability toabsorbandtransferheatenergy.The fan circulates air throughthe outer evaporator air coilthatactsasaheatcollector.Theliquid refrigerant in the air coil absorbstheavailableheatintheambientair,transformingitintoagas.Therefrigerantgasisthenpumped into the compressor.When this warmed gas is compressed, it intensifies or concentrates the heat, like a magnifying glass inthesun.Thisintenselyhotgasisthenpumpedintotheheatexchangercondenser,wheretheactualheattransfertakesplace.Asthepoolwaterpassesthroughtheheatexchanger,thehotgasgives up its heat to the cooler pool water.

How Efficient Is It ? This graph is a operational cost comparison for equal amountsofpoolheat.Asyoucanseeheatpumpisthe most efficient way to heat your pool.
ComparedtoL.P.gasheaters,aheatpumpproduces5 to 6 times more heat for every $1.00 you spend onoperation.
