Introduction

This manual contains important information on theuse, maintenance and troubleshooting of your newheat pump pool heater. This unit must be properlyinstalled, maintained and operated for optimal per-formance.

This heat pump pool heater is an extremely efficient,economical machine designed specifically for swim-ming pool heating. It is similar in design and operationto a typical residential air conditioning system. The unitemploys a hermetic motor/compressor operating in arefrigeration cycle to extract heat from ambient air anddeliver it to the circulating pool water.

As with all heat pump pool heaters, compared to othertypes of heaters such as gas or oil-fired, this heatpump pool heater has lower heating capacity on aBTUH/hr basis. As a result, it will be required to oper-ate longer to accomplish the desired results. It may, atcertain times, operate as much as 24 hours per day.However, this should not be of concern to the owner,because the unit is designed to operate continuously.Even though it may operate continuously for manyhours, it will still heat the pool with greater economythan other types of fossil fuel heaters.

Place a cover or blanket over the pool at night andother non-use periods. This will keep evaporation, thecause of main heat loss, to a minimum, and will great-ly reduce pool heating costs. During warmer weather,the cover may be required only at night.

Installation Considerations

Situate the heat pump pool heater carefully to mini-mize installation costs while providing maximumefficiency of operation, and to allow adequate serviceaccess, as follows:

• For unrestricted air intake and service access,position each side of the unit at least 1 ft (30 cm)from walls, pipes and other obstructions.

• Recirculation of cold discharge air back into theevaporator coil will greatly reduce the unit’s heat-ing capacity and efficiency.

• This unit features an ‘up-flow’ discharge for quietoperation. Air is pulled up through the evaporatorcoil and discharged through the top grill. Allow atleast 5 ft (1.5 m) clearance above the unit for unre-stricted air discharge. DO NOT install the unitunder a porch or deck. Refer to Fig. 1.

• To minimize water piping, locate the unit as closeas possible to the existing pool pump and filter.

• If the location of the heat pump pool heater isbelow the water line of the pool, the water pres-sure switch might need to be adjusted or anexternal water flow switch might be needed.

WARNING: This pool/spa heat pump pool heater isan electromechanical machine that incorporates apressurized refrigerant gas in a sealed system.ONLY trained and qualified service personnel areauthorized to install or service this equipment.Without proper training and knowledge of suchequipment, any attempt to install or service the unitcould result in serious injury or even death.

WARNING: Do not install the unit within 3 ft offossil fuel burning heaters. Air intake along thesides of this heat pump pool heater could disturbthe combustion process of the unit, and couldcause damage or personal injury.• Mount the unit on a level, sturdy base, preferably aconcrete slab or blocks. The size of the base shouldbe at least 3 ft by 3 ft.• You must install the 4 black rubber sound iso-lation pads (each 2 inches square) that ship withthe unit. The pads are shipped in a bag with theunions, gaskets and the I&O manual. Install padsunder the 4 corners of the unit to reduce vibra-tion and sound transmission to the base.

CAUTION: The unit’s supporting base must be highenough to keep it completely free of standing waterat all times.

WARNING: This unit is designed for outdoor instal-lation; DO NOT install it in an enclosed area such asa shed or garage.

Controls & Indicator Lamps(Analog Models)

Your analog heat pump pool heater incorporates safe-ty controls and indicators to ensure its safe, reliableoperation (for models with digital controls, see page11).

Water Pressure Switch: Prevents operation when thepump is OFF. The unit requires 5 psi minimum pres-sure.

Water Temperature Control: Pool/spa water temper-ature is controlled by the heat pump pool heaterthermostat on the unit control panel, which contains aswitch and 2 thermostats, one for setting a heat spatemperature and the other for a swimming pool tem-perature. The switch can operate an optional externalcontrol system, or can switch between thermostats forpool or spa.

Defrost Switch: Prevents heat pump pool heateroperation if ambient air temperature falls below a pre-determined safe minimum (approximately 42° F).

Delay Timer: Prevents compressor from short cycling,which could damage or destroy the hermeticmotor/compressor. Upon water temperature controlsatisfaction, or other circuit interruptions, this solidstate device will prevent compressor restart forapproximately 5 minutes.

Refrigerant Low Pressure Control: Stops the com-pressor if refrigerant suction (low side) pressure fallstoo low as a result of a malfunction, loss of charge orextreme cold conditions.

Indicator Lamps: There are 6 indicator lamps locatedon the unit control panel (see Fig. 3 below):

• Power (amber lamp):When lit, indicates power isapplied to the unit.

• Water Flow (green lamp):When lit, indicates nor-mal water flow.

• Heat Demand (green lamp): When lit, indicatesthe actual water temperature is below the targetwater temperature.

WARNING: Install a check valve and/or a Hartfordloop AFTER the heat pump pool heater andBEFORE any chlorinating devices. Install any auto-matic chemical feeders AFTER the heat pump poolheater. Improper installation of any type of auto-matic chemical feeders can result in seriousdamage to, or premature failure of, the heatpump pool heater and will void the heat pumppool heater warranty.

NOTE: The heat pump pool heater will not run whenthe Remote position is selected on the Pool/Spaselector switch and there is no remote control sys-tem attached.

• Compressor Delay Active (amber lamp): Undernormal operation, when lit, indicates compressoranti-short cycle timer is active. The fan will run butthe compressor will be OFF for 6 to 8 minutes.

• Defrost Active (red lamp):When lit, indicates unitis in defrost mode. Defrost mode occurs when icestarts to form on the outside coil. The fan will con-tinue to run but the compressor will stay OFF (notheating) until weather conditions improve.

• Low Pressure (red lamp): When lit, indicates fail-ure in the refrigeration circuit. When this lamp isON, service is required. Call for service assis-tance.

System Start-Up

1. Verify that the Power lamp is ON and that thepool/spa pump is running and circulating properly.

2. Verify that the control panel Spa-Remote-Poolswitch is in the Remote (OFF) position; see Fig. 4below.

3. Turn the control switch to either Pool or Spa toturn the system ON and raise the thermostat set-ting above the current water temperature. At thistime the 2 green lamps should illuminate. The fanand compressor should start up and run simulta-neously.

4. Allow the heat pump pool heater to operate for afew minutes to stabilize operating pressures and toallow various component temperatures to normal-ize.

5. Verify that the discharge air temperature is approx-imately 8°–10° cooler than the air entering the unit.If not, see the Troubleshooting Section.

Controls (Digital Models)

Your heat pump pool heater incorporates digital safetycontrols and indicators to ensure its safe, reliableoperation (for models with analog controls, see page10).

Water Pressure Switch: Prevents operation when thepump is OFF. The unit requires 5 psi minimum pres-sure.

Digital Water Temperature Control: The pool watertemperature is controlled by the heat pump poolheater’s digital control system, which gives you theoption of two settings: one for the desired spa temper-ature and the other for the desired pool temperature.Additionally, as mentioned earlier, the unit is compati-ble with most ‘2-wire’ and ‘3-wire’ control/automationsystems.

Defrost Sensor: Prevents unit operation if ambient airtemperature falls below a predetermined safe mini-mum (approximately 42°–48°F, based on humidity).The compressor will shut OFF but the fan will continueto run.

Delay Timer: Prevents compressor from short cycling,which could damage or destroy the hermeticmotor/compressor. Upon water temperature controlsatisfaction, or other circuit interruptions, this solidstate device will prevent compressor restart forapproximately 5 minutes.

System Start-Up

1. Verify that the Digital Board is displaying a temper-ature and the pool pump is running and water iscirculating properly.

2. Verify that the Board is programmed so that thedesired temperature of the Pool and Spa is higherthan the displayed current water temperature.

3. Allow the heat pump pool heater to operate for afew minutes to stabilize operating pressures and toallow various component temperatures to normal-ize.

4. Verify that the discharge air temperature is approx-imately 8°–10°F cooler than the air entering theunit. If not, see the Troubleshooting Section.

Seasonal Start-Up or AnnualCheck

1. Remove leaves, pine needles, etc., from the evap-orator coil. Clean the coil by gently applying a mildsolution of household liquid soap and water.

2. Gently rinse the coil with water; DO NOT use highpressure.

3. Backwash or otherwise clean the pool filter. If nec-essary, clean the skimmer basket and pumpstrainer.

4. Set the valves to ensure proper water flow throughthe unit.

NOTE: At the beginning of the heating season, orwhenever the pool water temperature is to be raisedseveral degrees, the pool pump and heat pump poolheater may need to operate continuously for severaldays. During summer months, only a few hours perday may be necessary, or none at all.

NOTE: If the pool pump and heat pump pool heatershut OFF before the water temperature is raised tothe desired level, you must lengthen the running timeof both. To do this, reset the time clock dial for thelonger running time, or manually operate the pumpwith the timer override switch. Since the heat pumppool heater capacity and efficiency are both greaterat higher ambient air temperatures, run time shouldbe set to take advantage of all daylight hours, whenthe air is generally warmer.

Summer Shutdown

If you do not plan to use the heat pump pool heaterduring the summer months, secure and protect it asfollows:

1. Turn the unit circuit breaker or disconnect switch toOFF.

2. Leave the valves set the way they are unless addi-tional circulation is required. DO NOT stop all flowthrough the heat pump pool heater.

3. IMPORTANT: Remember to reset the valvesbefore the next heating season, or the unit will notoperate properly.

Freeze Protection

If the unit is installed in a location subject to freezingconditions, it is important to protect the water circuitfrom freezing, just as should be done for the pump andfilter.

System Drain-Down

1. Turn the unit circuit breaker or disconnect switchto OFF.

2. With the pool pump OFF, close the external shut-off valves and loosen the inlet and outlet waterunions to allow water to drain. Use a Wet/Dry Vacor air pressure to remove excess water.

3. Loosely re-attach the unions.

4. Cover the unit with a waterproof cover.

Continuous Pump Operation

It is also possible in some areas to prevent unit freezedamage by operating the pump continuously duringfreezing weather. However, this results in significantlyhigher pump operating costs. Further, if a sustainedpower failure occurs, the unit MUST be drained any-way, or freeze damage could result.

Troubleshooting

If your unit does not operate, or simply does not heatyour pool water, Fault Codes (digital models), or theindicator lamps (analog models) on the front controlpanel, can provide valuable clues as to what is wrong,and may even indicate precisely what the problem is.Always observe these codes (or lamps) before callinga service representative. By reporting on the tele-phone the Fault Codes (or which lamps are ON orOFF) that are showing, the service rep may be able tosolve the problem without the expense of a servicecall.

A. UNIT IS RUNNING, BUT NOT HEATING

• Is water flow through the unit adequate? Checkthe unit for obstructions, such as a clogged filterpump strainer, a dirty filter, or valves not posi-tioned correctly.

• Is the ejected air from the unit 8°–10°F cooler thanincoming air? If so, the unit is extracting heat fromthe air and transferring it to the pool.

• Is water condensing on the evaporator and inter-nal copper pipes? This is also evidence of heatremoval from the air. When the air is cool with lowhumidity, condensation may not be evident.

• How long has the unit been operating? During ini-tial pool heating in cold weather, it may require aweek to elevate the water temperature to a com-fortable level. Normally, it takes about 4 days.

How many hours per day is the unit operating?Remember that the heat pump pool heater onlyoperates while the pool pump is running. Set thetime clock to permit 24 hour per day operation. Afterthe desired temperature is reached, return the unit tonormal operation of 8–10 hours per day.

Maintenance

The following maintenance procedures are designedto keep your unit operating at a high level of reliability.Maintenance must be performed on a periodicbasis to maintain warranty coverage and preventsystem failures and performance degradation.

Air Coil Cleaning

Efficient operation depends on free circulation of airthrough the thin and tightly-spaced fins of the evapo-rator coil(s). The evaporator must be cleanedwhenever it has a buildup of dirt or debris.

Cabinet Care (optional)

The cabinet is designed for outdoor use and requireslittle care. However, you can clean it if you wish.

Wash the cabinet with soap and water.

Unplug Condensation Drain Holes

The unit extracts humidity from the air as it passesthrough the coil, similar to the way a cold drink outside“sweats” on a hot day. This condensation drains fromthe bottom of the unit.

1. Routinely check to be sure the condensation drainholes in the base of the unit are not plugged withdirt or debris.

2. If condensation becomes a problem, optional drainpans are available from your heat pump poolheater distributor or pool dealer.

WARNING: Shut OFF electricity to the unit beforecleaning.

NOTE: The heat pump pool heater MANUFACTUR-ER IS NOT RESPONSIBLE for maintenanceadjustments.

CAUTION: To clean the fins, spray gently with agarden hose. DO NOT pressure wash. Doing sowill bend the fins and can void the warranty.

NOTE: If the compressor fails to start when ener-gized, and there are no faults detected in the wiring,contact the factory for the appropriate “Hard StartKit.”

• Is airflow through the unit being obstructed?Restrictions such as shrubbery, tall grass, dirtycoils, or any other obstruction to airflow will reduceperformance.

• Is the pool blanket/cover being used?Unblanketed pools can lose up to 10 degrees pernight compared to 4 degrees or fewer when ablanket is used. Without a blanket, the total heatgained during the day can be lost overnight.

• Are rapid heat losses occurring in some other way,such as high wind, spillage, rainfall, flow throughsolar panels at night, or a high water table?

B. UNIT IS NOT RUNNING

• Is the temperature display or control panel Powerlamp ON? If not, the circuit breaker may be shutOFF or tripped. Reset the breaker by switching itOFF, and then back ON. Verify that the breakeris set and operating properly before calling forservice.

• Is the thermostat setting and the Pool/Spa settingcorrect? Verify that the temperature has beenproperly set on the thermostat, and that it is high-er than the current water temperature. On analogunits, all 3 lamps should be illuminated and the fanshould begin to run.

• Have you waited approximately 5 minutes for thetime delay? After the unit has been running andthen shut OFF for any reason, there is a delaybefore operation can begin again.

• Is the Heat Light or Heat Demand lamp ON? Ifnot, then the thermostat setting is not higher thanthe temperature of the water. Raise the thermostatsetting.

NOTE: If the pool pump and heat pump pool heatershut OFF before the water temperature is raised tothe desired level, you must lengthen the running timeof both. To do this, reset the time clock dial for thelonger running time, or manually operate the pumpwith the timer override switch. Since the unit capaci-ty and efficiency are both greater at higher ambientair temperatures, run time should be set to takeadvantage of all daylight hours, when the air is gen-erally warmer.

C. CONDENSATION SEEMS EXCESSIVE

Heat pump pool heaters can produce a large amountof condensation (water) during operation. If you sus-pect that the unit is leaking:

a. Use a pool chemistry test kit to confirm there is nochlorine in the condensation. Or,

b. Shut the unit OFF and leave the filter pump run-ning to see if the water stops dripping. If the waterstops dripping, the unit is not leaking.

Service Call Verification

NOTE: The Raypak Service number is 800-260-2758.

Before you make a service call, first determine if theproblem is:

• Warranty Service

• Unit operation (power supply, water flow, or timeclock adjustment)

Power Supply

• Verify that all circuit breakers are reset and work-ing properly.

• If the temperature display or the Power lamp onthe control panel still does not light, contact theinstalling dealer, since it may be a power problemrequiring an electrician.

Water Flow

• Verify that the pool filter is clean to provide goodflow.

• Verify that valves are properly positioned to allowadequate water flow through the unit.

• If the Water Flow lamp (analog models) on thecontrol panel still does not light, and water is circu-lating in the pool, verify that all valves arepositioned correctly.

Time Clock Adjustment

Verify that the time clock is set to permit the unit to runlong enough to heat properly.

NOTE: The MANUFACTURER IS NOT RESPON-SIBLE for these adjustments.

NOTE: The heat pump pool heater will not run whenthe Remote position is selected on the Pool/Spaselector switch and there is no remote control sys-tem attached.
