DANGER:

WARNING:

CAUTION:

NOTE:

This manual, as well as the pool/spa heat pump pool heater itself, contains ANSI-approved product safety signs and labels. Please read these signs and labels, as they convey important safety information about hazards that may be potentially present in and around the heat pump pool heater.

CAUTION: Elevated water temperature can be hazardous. The U.S. Consumer Product Safety Commission has these guidelines:

1. Spa water temperatures should never exceed 104°F (40°C). A temperature of 100°F (38°C) is considered safe for a healthy adult. Special caution is suggested for young children.

Indicates the presence of immediate hazards which will cause severe personal injury, death or substantial property damage if ignored.

ndicates the presence of hazards or unsafe practices which could cause severe personal

I injury, death or substantial property damage if ignored.

Indicates the presence of hazards or unsafe practices which could cause minor personal injury or product or property damage if ignored.

Indicates special instructions on installation, operation, or maintenance which are important but not related to personal injury hazards.

CAUTION: Improper chemical content in a swimming pool or spa can damage the heat pump pool heater. DO NOT add pool chemicals to the skimmer. This will damage the heat pump pool heater and could void the heat pump pool heater warranty. ALWAYS follow the product manufacturer’s directions when adding any chemicals to your pool.

2. Drinking of alcoholic beverages before or during spa or hot tub use can cause drowsiness which could lead to unconsciousness and subsequently result in drowning.

3. Pregnant Women Beware! Soaking in water over 102°F (39°C) can cause fetal damage during the first three months of pregnancy resulting in the birth of a brain-damaged or deformed child. Pregnant women should stick to the 100°F (38°C) maximum rule.

4. Before entering the spa or hot tub, users should check the water temperature with an accurate thermometer; spa or hot tub thermostats may err in regulating water temperatures by as much as 4°F (2.2°C).

5. Persons with a medical history of heart disease, circulatory problems, diabetes, or blood pressure problems should obtain a physician's advice before using pools or hot tubs.

6. Persons taking medications which induce drowsiness, such as tranquilizers, antihistamines, or anticoagulants, should not use spas or hot tubs.

WARNING: These heat pump pool heaters are charged with R-410A refrigerant. Ensure that all service work is done with gauges and equipment suitable for R-410A.

Introduction

WARNING: This pool/spa heat pump pool heater is

an electromechanical machine that incorporates a pressurized refrigerant gas in a sealed system. ONLY trained and qualified service personnel are authorized to install or service this equipment. Without proper training and knowledge of such equipment, any attempt to install or service the unit could result in serious injury or even death.

This manual contains important information on the use, maintenance and troubleshooting of your new heat pump pool heater. This unit must be properly installed, maintained and operated for optimal performance.

This heat pump pool heater is an extremely efficient, economical machine designed specifically for swimming pool heating. It is similar in design and operation to a typical residential air conditioning system. The unit employs a hermetic motor/compressor operating in a refrigeration cycle to extract heat from ambient air and deliver it to the circulating pool water.

As with all heat pump pool heaters, compared to other types of heaters such as gas or oil-fired, this heat pump pool heater has lower heating capacity on a BTUH/hr basis. As a result, it will be required to operate longer to accomplish the desired results. It may, at certain 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 many hours, it will still heat the pool with greater economy than other types of fossil fuel heaters.

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

Installation Considerations

WARNING: Do not install the unit within 3 ft of

fossil fuel burning heaters. Air intake along the sides of this heat pump pool heater could disturb the combustion process of the unit, and could cause damage or personal injury.

• Mount the unit on a level, sturdy base, preferably a concrete slab or blocks. The size of the base should be at least 3 ft by 3 ft.

CAUTION: The unit’s supporting base must be high enough to keep it completely free of standing water at all times.

Situate the heat pump pool heater carefully to minimize installation costs while providing maximum efficiency of operation, and to allow adequate service access, 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.

WARNING: This unit is designed for outdoor installation; DO NOT install it in an enclosed area such as a shed or garage.

• Recirculation of cold discharge air back into the evaporator coil will greatly reduce the unit’s heating capacity and efficiency.

• This unit features an ‘up-flow’ discharge for quiet operation. Air is pulled up through the evaporator coil and discharged through the top grill. Allow at least 5 ft (1.5 m) clearance above the unit for unrestricted air discharge. DO NOT install the unit under a porch or deck. Refer to Fig. 1.

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

• If the location of the heat pump pool heater is below the water line of the pool, the water pressure switch might need to be adjusted or an external water flow switch might be needed.

• Irrigation water should be directed away from the heat pump pool heater-water spray can damage the heat pump pool heater.

• Rain water run offs- the heat pump pool heater can withstand normal rain. Install rain gutters to prevent direct steams of rain water to the heat pump pool heater.

• It is important to keep the area next to the heat pump pool heater clear of shrubs, bushes and chemicals containers. They could prevent air from circulating fully through the heat pump pool heater, and will affect the operation of the heat pump pool heater or damage the heat pump pool heater.

• When installed in areas where freezing temperatures can be encountered, drain the water circuit to prevent possible freeze-up damage. See the Freeze Protection Section.

Water Connections

AUTION: The heat pump pool heater inlet and

outlet connections are NOT interchangeable. They

ust be connected as instructed below.

1. Connect the heat pump pool heater in the return water line between the filter and the pool/spa. See the Plumbing Diagrams beginning on page 14.

2. Connect the filter outlet to the fitting marked WATER IN at the bottom front of the unit.

3. Connect the fitting marked WATER OUT to the return piping to the pool/spa. Unit inlet/outlet connection fittings are 1-1/2 inch PVC unions.

Water connections from the unit to the main return line can be PVC pipe or flexible pipe approved for the purpose and, in either case, should be at least equal in size to the main pool/spa circulation piping.

. In cold weather (freeze zone) areas, shutoff valves

(ball or gate type) must be installed at the unit inlet and outlet to facilitate service and cold weather drain-down.

5. Operate the pump and check the system for leaks.

WARNING: Install a check valve and/or a Hartford loop AFTER the heat pump pool heater and BEFORE any chlorinating devices. Install any automatic chemical feeders AFTER the heat pump pool heater. Improper installation of any type of auto-

matic chemical feeders can result in serious damage to, or premature failure of, the heat pump pool heater and will void the heat pump pool heater warranty.

Fig. 3: Utility Connections

NOTE: Units are provided with 1/4” service ports, as shown in Fig. 3 above. The upper port is for measuring high pressure, and the lower port is for measuring the low pressure.

CAUTION: Caps must be reinstalled after service is complete.

Controls

our heat pump pool heater incorporates digital safety

Y controls and indicators to ensure its safe, reliable operation.

ater Pressure Switch: Prevents operation when the

pump is OFF. The unit requires 5 psi minimum pressure.

Digital Water Temperature Control: The pool water temperature is controlled by the heat pump pool heater’s digital control system, which gives you the option of two settings: one for the desired spa temperature and the other for the desired pool temperature. Additionally, as mentioned earlier, the unit is compatible with most ‘2-wire’ and ‘3-wire’ control/automation systems.

Defrost Sensor: Prevents unit operation if ambient air temperature falls below a predetermined safe minimum (approximately 42°–48°F (5.5°–8.8°C), based on humidity). The compressor will shut OFF but the fan will continue to run.

Delay Timer: Prevents compressor from short cycling, which could damage or destroy the hermetic motor/compressor. Upon water temperature control satisfaction, or other circuit interruptions, this solid state device will prevent compressor restart for approximately 5 minutes.

Controls Operating Instructions

The electronic board has the capability of memorizing two different programmed temperature settings as follows (refer to Fig. 4):

• For a pool, maximum 95°F (35°C)

• For a spa, maximum 104°F (40°C)

To Select Pool or Spa Mode

To have access to either one of these programs, press the SET key until you see P _S and by pressing the UP or DOWN key you can switch to POL or SPA.

To Increase the Desired Water Temperature (Pool or Spa Mode)

Push the SET key until you see POL or SPA. The programmed temperature will be displayed. Press the UP arrow to increase the temperature setting one degree at a time.

To Lower the Desired Water Temperature (Pool or Spa Mode)

Push the SET key until you see POL or SPA. The programmed temperature will be displayed. Press the DOWN arrow to decrease the temperature setting one degree at a time.

Fig. 4: Digital Water Temperature Control

Once the control has been programmed to the desired pool water temperature, the programmed temperature will be displayed for approximately 5 seconds. Then the digital display will display the actual pool water temperature.

To make the Board a Pool ONLY Board, call 800260-2758 for instructions.

To Select Temperature in °C or °F

Press the SET key until you see F _C. By pressing the UP or DOWN key you can switch to °F or °C. Once the temperature display mode has been programmed it will be displayed for approximately 5 seconds, then the digital display will return to the actual pool water temperature in the mode that you have chosen.

System Start-Up

. Verify that the Digital Board is displaying a temper-

ature and the pool pump is running and water is circulating properly.

Summer Shutdown

f you do not plan to use the heat pump pool heater

I during the summer months, secure and protect it as follows:

2. Verify that the Board is programmed so that the

desired temperature of the Pool and Spa is higher than the displayed current water temperature.

3. Allow the heat pump pool heater to operate for a

few minutes to stabilize operating pressures and to allow various component temperatures to normalize.

4. Verify that the discharge air temperature is approx-

imately 4°–5°F (2.2°–2.8°C) cooler than the air entering the unit. If not, see the Troubleshooting Section.

Seasonal Start-Up or Annual Check

NOTE: At the beginning of the heating season, or

whenever the pool water temperature is to be raised several degrees, the pool pump and heat pump pool heater may need to operate continuously for several days. During summer months, only a few hours per day may be necessary, or none at all.

1. Remove leaves, pine needles, etc., from the evap-

orator coil. Clean the coil by gently applying a mild solution of household liquid soap and water.

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

pressure.

1. Turn the unit circuit breaker or disconnect switch to OFF.

2. Leave the valves set the way they are unless additional circulation is required. DO NOT stop all flow through the heat pump pool heater.

3. IMPORTANT: Remember to reset the valves before the next heating season, or the unit will not operate properly.

Freeze Protection

If the unit is installed in a location subject to freezing conditions, it is important to protect the water circuit from freezing, just as should be done for the pump and filter.

System Drain-Down

1. Turn the unit circuit breaker or disconnect switch to OFF.

2. With the pool pump OFF, close the external shutoff valves and loosen the inlet and outlet water unions to allow water to drain. Use a Wet/Dry Vac or air pressure to remove excess water.

3. Loosely re-attach the unions.

4. Cover the unit with a waterproof cover.

3. Backwash or otherwise clean the pool filter. If necessary, clean the skimmer basket and pump strainer.

NOTE: If the pool pump and heat pump pool heater shut OFF before the water temperature is raised to the desired level, you must lengthen the running time of both. To do this, reset the time clock dial for the longer running time, or manually operate the pump with the timer override switch. Since the heat pump pool heater capacity and efficiency are both greater at higher ambient air temperatures, run time should be set to take advantage of all daylight hours, when the air is generally warmer.

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

Continuous Pump Operation

It is also possible in some areas to prevent unit freeze damage by operating the pump continuously during freezing weather. However, this results in significantly higher pump operating costs. Further, if a sustained power failure occurs, the unit MUST be drained anyway, or freeze damage could result.

Maintenance

Troubleshooting

OTE: The heat pump pool heater MANUFACTUR-

ER IS NOT RESPONSIBLE for maintenance

djustments.

he following maintenance procedures are designed

T to keep your unit operating at a high level of reliability.

Maintenance must be performed on a periodic basis to maintain warranty coverage and prevent

system failures and performance degradation.

Air Coil Cleaning

Efficient operation depends on free circulation of air through the thin and tightly-spaced fins of the evaporator coil(s). The evaporator must be cleaned whenever it has a buildup of dirt or debris.

CAUTION: To clean the fins, spray gently with a garden hose. DO NOT pressure wash. Doing so will bend the fins and can void the warranty.

Cabinet Care (optional)

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

WARNING: Shut OFF electricity to the unit before cleaning.

Wash the cabinet with soap and water.

Unplug Condensation Drain Holes

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

1. Routinely check to be sure the condensation drain holes in the base of the unit are not plugged with dirt or debris.

2. If condensation becomes a problem, optional drain pans are available from your heat pump pool heater distributor or pool dealer.

If your unit does not operate, or simply does not heat your pool water, Fault Codes on the front control panel, can provide valuable clues as to what is wrong, and may even indicate precisely what the problem is. Always observe these codes before calling a service

epresentative. By reporting on the telephone the Fault

r Codes that are showing, the service rep may be able to solve the problem without the expense of a service call.

A. UNIT IS RUNNING, BUT NOT HEATING

• Is water flow through the unit adequate? Check

the unit for obstructions, such as a clogged filter pump strainer, a dirty filter, or valves not positioned correctly.

• Is the ejected air from the unit 4°–5°F (2.2°–2.8°C)

cooler than incoming air? If so, the unit is extracting heat from the air and transferring it to the pool.

• Is water condensing on the evaporator and internal copper pipes? This is also evidence of heat removal from the air. When the air is cool with low humidity, condensation may not be evident.

• How long has the unit been operating? During initial pool heating in cold weather, it may require a week to elevate the water temperature to a comfortable level. Normally, it takes about 4 days.

How many hours per day is the unit operating?

Remember that the heat pump pool heater only operates while the pool pump is running. Set the

time clock to permit 24 hour per day operation. After the desired temperature is reached, return the unit to normal operation of 8–10 hours per day.

NOTE: If the pool pump and heat pump pool heater shut OFF before the water temperature is raised to the desired level, you must lengthen the running time of both. To do this, reset the time clock dial for the longer running time, or manually operate the pump with the timer override switch. Since the unit capacity and efficiency are both greater at higher ambient air temperatures, run time should be set to take advantage of all daylight hours, when the air is generally warmer.

• Is airflow through the unit being obstructed? Restrictions such as shrubbery, tall grass, dirty coils, or any other obstruction to airflow will reduce

erformance.

Service Call Verification

he Service number is 800-260-2758 in the United

T States. For units in Canada, call 800-268-6966.

• Is the pool blanket/cover being used? Unblanketed pools can lose up to 10°F (5.5°C) per night compared to 4°F (2.2°C) or fewer when a blanket is used. Without a blanket, the total heat gained during the day can be lost overnight.

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

B. UNIT IS NOT RUNNING

• Is the temperature display ON? If not, the circuit

breaker may be shut OFF or tripped. Reset the breaker by switching it OFF, and then back ON.

Verify that the breaker is set and operating properly before calling for service.

• Is the thermostat setting and the Pool/Spa setting

correct? Verify that the temperature has been properly set on the thermostat, and that it is high-

er than the current water temperature.

• Have you waited approximately 5 minutes for the

time delay? After the unit has been running and then shut OFF for any reason, there is a delay before operation can begin again.

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

• Warranty Service

• Unit operation (power supply, water flow, or time

clock adjustment)

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

Power Supply

• Verify that all circuit breakers are reset and working properly.

• If the temperature display does not light, contact the installing dealer, since it may be a power problem requiring an electrician.

Water Flow

• Verify that the pool filter is clean to provide good flow.

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

• Is the Heat Light ON? If not, then the thermostat setting is not higher than the temperature of the water. Raise the thermostat setting.

NOTE: The heat pump pool heater will not run when the Remote position is selected on the Pool/Spa selector switch and there is no remote control system attached.

C. CONDENSATION SEEMS EXCESSIVE

Heat pump pool heaters can produce a large amount of condensation (water) during operation. If you suspect that the unit is leaking:

a. Use a pool chemistry test kit to confirm there is no

chlorine 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 water stops dripping, the unit is not leaking.

Time Clock Adjustment

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

Installing a Remote Control Device

Wiring

For a 2-wire control, use the TOTAL and COMMON connections on the heat pump pool heater wiring block.

For a 3-wire control, use the COMMON, SPA and POOL connections on the heat pump pool heater wiring block.

Fault Code Meaning of Code

OFF The desired programmed temperature point is lower than 60°F (15°C).

Shortage of refrigerant gas in the unit or faulty low pressure control. The unit will show

LP & LP3

(LP3) after 3 LP faults and shuts down the unit and pool pump for protection. If this occurs, you should call for service.

HP & HP6

Low water flow in the unit or faulty high pressure control. Check water flow/backwash. The unit will show (HP6) after 6 HP faults. This will stop the unit for protection.
