NOTE: The model AT600 has a slightlydifferent control panel configuration.
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.

Plumbing & Water ConnectionsFor a simple pool only or spa only, install the plumbing piping as shown:Connections from factory are 2” pipe slip.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 CHEMICAL TRAP LOOP at least 6 to 8 inches above the chlorinator/feeder topto prevent chlorine backup into the heater when the water pump is off. All chemical feedersshould be installed DOWN LINE of the heater. All feeders should be installed at the same orbelow the heater 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 below90 p.p.m. DO NOT allow the chlorine to go above 5 p.p.m. for extended periods. Chemicaldamage is not covered by 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.

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.

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 back-up to 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 25 flow switchand disabling the internal water pressure switch. Plumb in the flow switch as shown here. Then run aTHREE wire insulated cable from the flow switch into the heater and attach to the existing waterpressure switch leads located behind the large service panel and wire as shown below.

Optional One Touch Pool & Spa Control WiringThe Model 120, 90 and AT600 can be retrofitted with our simple, automated “one touch” pool/spa combination control. The one touch control will perform the following functions when youswitch from pool mode to spa mode: Activate the two included Jandy™ 2440 actuator motors.Activate the spa thermostat. Override the filter pump time clock to start the water pump, keep-ing it running while in spa mode.
Installation of the one touch control is as follows: Mount the one-touch control box near thewater pump timer. Run conduit with four #14 or #12 A.W.G. wires between the time clock andthe control. The wiring to water pump time clock is similar to what is shown on page 9. NOTE:For models 120 & 90 only, the optional time clock override (shown on page 9), will have it’s ownindependent high voltage wires to the time clock as well.
Run a 3 wire insulated cable (18 to 16 A.W.G.) from the control through the heat pumps lowvoltage access port located on the right side of the heater and wire as shown here. Mount theone touch selector switch in the pool area (must be 6 feet from pool/spa water !). Run your“field installed” insulated switch cable to the control box and wire as shown here. Switch cableup to 25 feet must have a minimum wire size of #16. Increase the switch cable wire size to #14A.W.G if over 25 feet, at a maximum of 50 feet. Review wiring diagrams on pages 14 & 15 forthe appropriate model number being installed.
Assuming the plumbing is similar to the schematic on page 6 and Jandy brand 3-way valves arein place, mount the supplied Jandy actuator motors, one on the suction valve and one on thereturn valve. Label the piping on either side of the motor valves (pool or spa) so the valveposition can be identified by the user. The actuator motor wires come already attached to the one touchcontrol, if not, wire them as shown on page 11.

NOTE 1: There are colored wire extensions connected to the relays inside the one touch controlfor the time clock override and the pool/spa select connections. Wire nut your wire to eachaccordingly. The Jandy JVA2440 actuator motors come from the factory already attached to theswitching relay, if not, attach as shown here. REVIEW WIRING DIAGRAMS ON PAGE 14 & 15ALSO !NOTE 2: The heaters pool/off/spa switch will be disabled when the one touch is installed.NOTE 3: Use a 3 wire insulated cable between the heater and the one touch control box that isa minimum size of 18 to 16 A.W.G. wire.NOTE 4: An air button type pool/spa select switch can be ordered in place of the toggle typeswitch as long as there is conduit running to the pool area. Specify when ordering.
To interface the heat pump with the Jandy™ AquaLink RS series or Compool, run a 2 wire (16A.W.G. or larger) insulated cable from the device to the heat pump. If you are using a JandyAquaSwitch or JI2000 control use a 3 wire cable. Review wiring diagrams on page 14 & 15.
Remove the 6 screws from the heaters front service access panel and open. Look for the wiringharness leading to the back of the service panel where the orange and black terminal bars meet.You will find two orange wires attached to a separate (white) two position terminal. A orangeloop wire is on one side of this terminal, it must be removed & discarded. Then, attach the 2wire cable coming from the AquaLink RS or the Compool control to the 2 position terminalwhere 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.

BLUE HEATING LIGHT: This light indicates that the unit is heating and the compressor is running.The compressor starts after a 5 to 7 minute time delay. NOTE: The water pump must be runningat the same time in order for the heater to run. NOTE: For older units prior to February 2000, thislight will come on whenever the thermostat is calling for heat.GREEN POWER LIGHT: This light indicates that the heater has control power. WARNING: This isnot a line power indicator and caution should be used since more than one power disconnec-tion may be required to isolate the heater electrically. WARNING: If the optional Time ClockOverride is installed, you must shut off the water pumps main power disconnect as well.AMBER NO WATER FLOW LIGHT: This light indicates there is no water flow through the heater.The heater is designed to shut off whenever the water pump is not pumping water through theheater. If this light is on while the water pump is running, the water pump may not be supplyingenough flow for the heater to operate properly. During normal operation the heater turns off andon with the water pump, (as long as the thermostat is calling for heat).RED FAULT LIGHT: This light indicates that the internal safety control system has disabled theheater. If either the high or low refrigerant pressure switch has tripped this light will come on.During cold weather where the air temperature drops below approximately 45 degrees (de-pending on humidity), the low refrigerant pressure switch (or defrost control) is designed todisable the compressor only. In this “defrost mode” the fan will continue to run through the 5 to7 minute time delay and/or until the outside air temperature increases to the operational rangebefore the compressor will attempt to restart. The heater should be shut off when the air tem-perature is expected to drop below the operational range for an extended period. Units madeprior to February 2000 the fan and compressor will shut off in defrost mode.The high refrigerant pressure switch is designed to shut the compressor and fan off if a heatbuildup occurs for whatever reason. Typically the high refrigerant pressure switch will trip if thewater flow through the heater is restricted. It may also trip if the air flow is restricted through theheater.NOTES: The heater should never run without water running through it from the filter pump. Theheater will not heat faster if you turn the thermostat knob up higher. The Time Clock overridemode may cycle the water pump on and off periodically to sample the pool water temperature.This cycling will be excessive if the Time Clock Override is used during warmer weather condi-tions when pool heat loss is minimal.
TEMPERATURE CONTROLS: The top Thermostatcontrols the pool temperature. The bottom Thermo-stat controls the spa temperature. If you do not havea spa you can use the two thermostats as a high andlow temperature preset.
THERMOSTAT/OFF SWITCH- POOL/OFF/SPA: TheThermostat/Off Switch determines which thermo-stat is active, up for pool, down for spa. You candisable the heater by placing the selector switch inthe center “OFF” position.
RESET TRIPPER BUTTON: The Reset Button will tripif there is some sort of short or ground fault in thecontrol wiring. The reset has a grey rubber cover.When the reset has been tripped, the reset plungersprings forward into the rubber cover so it can bereset. You can not feel the plunger switch behindthe rubber cover unless it has been tripped.
“OPTIONAL” WATER PUMP TIME CLOCK OVERRIDESWITCH: When this switch is in the ON positionthe Time Clock Override feature is designed to startthe water pump whenever the pool requires heat.When this switch is in the OFF mode position, theheater will operate only when the water pump isrunning during the timed period set on the time
clock. NOTE: The time clock override works best if used during cooler weather conditions wherethe pool is loosing more than 8 to 10 degrees over night or when the pool is being heated from“dead cold”. This option is factory installed as specified when ordered.

RED POWER LIGHT: This light indicatesthat the heater has control power.WARNING: This is not a line power in-dicator and caution should be usedsince more than one power disconnec-tion may be required to isolate theheater electrically.
BLUE HEATING LIGHT: This light indicates that the unit is heating and the compressor is running.The compressor starts after a 5 to 7 minute time delay. NOTE: The water pump must be runningat the same time in order for the heater to run. NOTE: For units prior to February 2000, this lightwill come on whenever the thermostat is calling for heat.
AMBER FAULT LIGHT: This light indicates that one of the internal refrigerant safety controls hasdisabled the heater. The amber light indicates that the low refrigerant pressure switch or the highrefrigerant pressure switch has opened for whatever reason.
During cold weather where the air temperature drops below approximately 45 degrees (de-pending on humidity), the low refrigerant pressure switch (or defrost control) is designed todisable the compressor only. In this “defrost mode” the fan will continue to run through the 5 to7 minute time delay and/or until the outside air temperature increases to the operational rangebefore the compressor will attempt to restart. The heater should be shut off when the air tem-perature is expected to drop below the operational range for an extended period.
The high refrigerant pressure switch is designed to shut the compressor and fan off if a heatbuildup occurs for whatever reason. Typically the high refrigerant pressure switch will trip if thewater flow through the heater is restricted. It may also trip if the air flow is restricted through theheater.
NOTES: The heater should never run without water running through it from the filter pump. Theheater is designed to shut off whenever the water pump is not pumping water through theheater (no indicator light). The heater will not heat faster if you turn the thermostat knob uphigher. Units made prior to February 2000 the fan and compressor will shut off in defrost mode.
TEMPERATURE CONTROLS: The rightThermostat controls the pool tempera-ture. The left Thermostat controls thespa temperature. If you do not have aspa you can use the two thermostatsas a high and low temperature preset.
THERMOSTAT/OFF SWITCH- POOL/OFF/SPA: The Thermostat/Off Switchdetermines which thermostat is active,move the switch to the right for poolmode, move the switch to the left forspa mode. You can disable the heaterby placing the selector switch in thecenter “OFF” position.

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 heat collector. The liquidrefrigerant in the air coil absorbs the available heat in the ambient air, transforming it into a gas. Therefrigerant gas is then pumped into the compressor. When this warmed gas is compressed, itintensifies or concentrates the heat, like a magnifying glass in the sun.
This intensely hot gas is then pumped into the heat exchanger condenser, where the actual heattransfer takes place. As the pool water passes through the heat exchanger, the hot gas gives up itsheat to the cooler pool water.
The refrigerant returns to a liquid state and is pumped through the expansion valve then into theevaporator air coil to start the process all over again.
