WARNING

A swimming pool & spa pump utilizes proven refrigerant technology to capture the heat in theoutside air and transfers it to the pool water. Refrigerant is used because of its ability to absorb andtransfer heat energy. The fan circulates air through the outer evaporator air coil that acts as a heatcollector. The liquid refrigerant in the air coil absorbs theavailable heat in the ambient air, transforming it into agas. The refrigerant gas is thenpumped into the compressor.When this warmed gas is com-pressed, it intensifies or concen-trates the heat, like a magnifyingglass in the sun.This intensely hot gas is thenpumped into the heat ex-changer condenser, where theactual heat transfer takes place.As the pool water passesthrough the heat exchanger, thehot gas gives up its heat to the cooler pool wa-ter. The refrigerant returns to a liquid state andis pumped through the expansion valve theninto the evaporator air coil to start the process allover again.

How Does A Heat Pump Warm My Pool ?

How Efficient Is It ?This graph is a operational cost comparison for equalamounts of pool heat. As you can see heat pump isthe most efficient way to heat your pool.

Compared to L.P. gas heaters, a heat pump produces5 to 6 times more heat for every $1.00 you spendon operation.

NOTICE: UNIT REQUIRES TWO, 2 INCHFEMALE ADAPTORS FOR PLUMBINGCONNECTIONS

1. To allow for proper condensation drain-age, use a level slab to elevate the heat pumpto at least the same height as the pool filtersystem slab or 2 to 3 inches “minimum” abovegrade.

2. Allow the minimum air flow clearanceson top and the sides as shown here. Makesure the unit can “breathe” well. Do not in-stall indoors or where the discharge air canaccumulate and be drawn back through theheater. Make sure the front is accessiblefor future service.

3. Keep sprinkler heads at least 6 feet awayfrom the heat pump. Do not allow the sprin-kler to spray the unit in any way to preventdamage.

4. If the unit is installed under a sharp roofpitch or under a roof valley without a gutter,a gutter or diverter should be fitted to pre-vent excessive water from rushing through theunit.

5. Keep all plants and shrubs trimmed awayfrom the heater to the minimum clearancesshown here to prevent air coil damage.

6. If the heater is installed above or belowthe pool water level by more than 3 feet youmay require an external water flow switch.See the bottom of page 7 for more informa-tion.

WATER IN-OUT PORTINDICATOR LABEL

2” THREADED MALEPIPING CONNECTIONS

Plumbing & Water Connections - 2” Threaded MaleFor a simple pool only or spa only, install the plumbing piping as shown:Connections from factory are 2” threaded male pipe, requiring 2 inch female adaptors, see diagram.Use teflon tape and pipe sealer. Tighten hand tight plus 1/2 snug tight with pliers.Water IN on the RIGHT, Water OUT on the LEFT,PLUMB AFTER the FILTER & BEFORE any CHLORINATORS or CHEMICAL FEEDERS

Be sure to install a CHECK VALVE & CHEMICAL TRAP LOOP as shown. The loop should be at least6 to 8 inches above the chlorinator/feeder top to prevent chlorine backup into the heater when thewater pump is off. Install a 2# check valve on the heater side of the loop as shown above toprevent chlorine from damaging it. All feeders should be installed at the same or below theheater piping elevation to prevent chemical back up into the heater.DO NOT : Install the heater down stream from any chemical feeders.DO NOT : Allow chemical feeders on the suction side of the water pump.DO NOT : Allow any chemicals or chlorine to be fed through the skimmer.DO NOT : Allow the pool water pH to go below 7.4. DO NOT allow the alkalinity to go below 90 p.p.m.DO NOT : Allow the chlorine to go above 5 p.p.m. for extended periods. Chemical damage is not coveredby and may void warranty.

Bypass for Flow Rates Over 70 G.P.M.Typically the automatic internal water by-pass can handle up to a 1.5 H.P. waterpump or 70 G.P.M. If the water pump ex-ceeds 1.5 H.P. then install either of the op-tional bypasses as shown below.

Plumb multiple units as shown below. Use flowmeters on each WATER OUT line if two or moreunits are plumbed together.

Freezing Condition PlumbingIn areas where extended freezing conditions exist, the heater must beplumbed as shown so it can be winterized. Water left inside the heaterwill freeze and cause damage. Plumb in a union, shut off valve, a boilerdrain and a air petcock valve on the water in and water out lines asshown here. Isolate the heater with the shut off valves and use pressur-ized air to clear the heat exchanger of all water. In areas where freezingconditions are temporary, the water pump should be set to run 24 hoursto prevent freezing. Freeze damage will void warranty.

Multi Unit Water Connections

OFF

Ball Valve orJandy™ 3-Way

The installation of a flow meter on the WATEROUT line is suggested. Adjust the bypass todivert a minimum of 40 to 50 G.P. M. throughthe heater. Flow meters should be installed perthe manufacturers instructions.

Use ball valves to balance the water flow through eachunit. Using T’s, caps and a minimum 6 inch pipe exten-sion on the plumbing manifold will help equalize thewater flow better than 90˚’s. Flow meters should be in-stalled per the manufacturers instructions.

See page 6 for pool/spaplumbing diagrams.

Plumbing & Water Connections with SolarPlumbing for a system where asolar pool heater is installed. It isstrongly advised that an auto-matic solar control device beused when used with the heatpump.

The heat pump and solar can beoperated together. The heatpump will share the heating loadwith the solar. If there is no heatcoming from the solar panels, thesolar control device will turn offthe solar by rotating the motorvalve, otherwise it should beturned off manually. The heatpump will then maintain thepool/spa temperature.

To use the heat pump as a backupto the solar, set the heat pumpthermostat 2 to 4 degrees belowthe solar’s target temperature set-ting. Therefore, if the solar is notmaintaining water temperature,the heat pump will come on toassist the solar. Some thermostatfine tuning may be required bythe user.

If you install the heat pump above or below the pool or spa water level by more than 3 feet, the internalwater pressure switch may be effected by the static pressure of the pool water. In some cases it maybe necessary to install a water FLOW switch. The water flow switch is not effected by changes inwater pressure but only water movement. We suggest installing the Grid Brand Model 20 or 25, externalflow switch and disabling the internal water pressure switch. Plumb in the flow switch as shown here.Then run a THREE wire insulated cable from the flow switch into the heater and attach to the existingwater pressure switch leads located behind the large service panel and wire as shown below.REVIEW PAGE 8 FOR SIMILAR ACCESS TO LARGE ELECTRICAL SERVICE COMPARTMENT BE-FORE CONTINUING.

To interface the “Prologic” analog control heat pump models with the Jandy™ AquaLink RSseries or Compool, run a 2 wire (16 A.W.G. or larger) insulated cable from the device to the heatpump. If you are using a Jandy AquaSwitch or JI2000 control use a 3 wire cable. Review wiringdiagram on page 10.

Remove the 6 screws from the heaters front service access panel and open. Look for a white,two position wire terminal located inside the top portion of the electrical compartment and ismounted on the rear wall. (Do not confuse it with the 4 position, white terminal blockabove it !) Locate, remove and discard the orange wire loop attached at the bottomend of this terminal. Then, attach the 2 wire cable coming from the AquaLink RS or the Compoolcontrol to the 2 position terminal where the orange loop was prior, see page 13.

NOTE for AquaLink RS andCompool: Turn both heater ther-mostats all the way up and setthe mode selector switch topool and do not use the heatercontrols as the Jandy orCompool now has thermostatcontrol over the heater.

For AquaSwitch and JI2000:The heater’s thermostats still con-trol the heater and should bepreset to the desired pool andspa temperature. The pool/spaselect switch should be left onpool mode and will be inactiveas the AquaSwitch or JI2000 hasswitching control over theheater.

NOTE: Other nonthermostat type ofcontrols hook up thesame way shownhere.

The control will uti-lize the heaters t-stats, the control willswitch between pooland spa t-stat.

Leave the heater’sswitch in pool mode.

NOTE: The controlwill have thermostatcontrol over heater.Turn the heater’s t-stats all the way upand leave the switchin pool mode.

TEMPERATURE CONTROLS: The top Thermostat controls the pool temperature. Thebottom Thermostat controls the spa temperature. If you do not have a spa you can usethe two thermostats as a high and low temperature preset.

THERMOSTAT/OFF SWITCH- POOL/OFF/SPA: The Thermostat/Off Switch determineswhich thermostat is active, up for pool, down for spa. You can disable the heater byplacing the selector switch in the center “OFF” position.

GREEN POWER LIGHT: This light indicates that the heater has control power. WARN-ING: This is not a line power indicator and caution should be used since more than onepower disconnection may be required to isolate the heater electrically. WARNING: Ifthe optional Time Clock Override is installed, you must shut off the water pumps mainpower disconnect as well.

BLUE HEATING LIGHT: This light indicates that the unit is heating and the compressoris running. The compressor starts after a 5 to 7 minute time delay. NOTE: The waterpump must be running at the same time in order for the heater to run.

AMBER NO WATER FLOW LIGHT: This light indicates there is no water flow through theheater. The heater is designed to shut off whenever the water pump is not pumpingwater through the heater. If this light is on while the water pump is running, the waterpump may not be supplying enough flow for the heater to operate properly. Duringnormal operation the heater turns off and on with the water pump, (as long as thethermostat is calling for heat).

RED FAULT LIGHT: This light indicates that the internal safety control system has dis-abled the heater. If either the high or low refrigerant pressure switch has tripped thislight will come on. NOTE: During cold weather where the air temperature dropsbelow approximately 45 to 50 degrees (depending on humidity), the low refrig-erant pressure switch (or defrost control), is designed to disable the heater. Inthis “defrost mode” the fan and compressor will shut off. When the defrostswitch resets for whatever reason the fan will restart, then after a 5 to 7 minutetime delay the compressor will attempt to restart. In some case where the airtemperature are in a borderline range, the heater my cycle on & off in an at-tempt to reset. The heater should be shut off when the air temperature is ex-pected to drop below the operational range for an extended period. The highrefrigerant pressure switch is designed to shut the compressor and fan off if a heatbuildup occurs for what ever reason. Typically the high refrigerant pressure switch willtrip if the water flow through the heater is restricted. It may also trip if the air flow isrestricted through the heater.

NOTES: The heater will never run without water running through it from the filter pump.The heater will not heat faster if you turn the thermostat knob up higher.
