To the User: This manual contains

important information that will help you in operating and maintaining this heat pump. Please retain it for future reference.

1.2 Consumer Information and Safety

The EE-Ti series of heat pumps are designed and manufactured to provide many years of safe and reliable service when installed, operated and maintained according to the information in this manual and the installation codes referred to in later sections. Throughout the manual, safety warnings and cautions are identified by the “ comply with all of the warnings and cautions.

“ symbol. Be sure to read and

AVISO

Al utilizar el spa, deberán observarse, las siguientes “Reglas de Seguridad para Baños Calientes” recomendadas por la Comisión de Seguridad de Productos para el Consumidor de los Estados Unidos.

1. Spa or hot tub water temperature should never exceed 104°F (40°C). One hundred degrees Fahrenheit (100°F [38°C]) is considered safe for a healthy adult. Special caution is recommended for young children.

2. The 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.

Page 4

Jandy Heat Pump Models EE-Ti Installation and Maintenance Manual

3. Pregnant women take note! Soaking in water

above 102°F (38.5°C) can cause fetal damage during the ﬁ rst three (3) months of pregnancy (which could result in the birth of a brain-damaged or deformed child). If pregnant women are going to use a spa or hot tub, they should make sure the water temperature is below 100°F (38°C) maximum.

4. The water temperature should always be checked with an accurate thermometer before entering a spa or hot tub. Temperature controls may vary by as much as 1F° (1°C).

5. Persons with a medical history of heart disease, diabetes, circulatory or blood pressure problems should consult their physician before using a hot tub or spa.

6. Persons taking any medication which induces drowsiness (e.g., tranquilizers, antihistamines, or anticoagulants) should not use spas or hot tubs.

7. Prolonged immersion in hot water can induce hyperthermia.

Hyperthermia occurs when the internal body

temperature reaches a level several degrees above the normal body temperature of 98.6°F (37°C). Symptoms include dizziness, fainting, drowsiness, lethargy, and an increase in the internal body temperature. The effects of hyperthermia include:

• Lack of awareness of impending hazard

• Failure to perceive heat

• Failure to recognize need to leave spa

• Physical inability to leave spa

• Fetal damage in pregnant women

• Unconsciousness resulting in a danger of drowning

1.2.2 Swimming Pool Energy Saving Tips

It is important to note that a heat pump will not

heat a pool as fast as a large gas or electric pool heater. If the pool water is allowed to cool significantly, it may take several days to return to the desired swimming temperature. For weekend use, it is more economical to maintain the pool water temperature at or near your desired swimming temperature. If you do not plan to use your pool for a prolonged period, then you might choose to turn the heat pump completely off or decrease the temperature setting of the control several degrees to minimize energy consumption.

Zodiac offers the following recommendations to

help conserve energy and minimize the cost of operating your heat pump without sacrificing comfort.

1. The American Red Cross recommends a maximum water temperature of 78°F (25°C). Use an accurate pool thermometer. A difference of 4°F (2°C), between 78°F and 82°F (26°C and 28°C), will signiﬁ cantly increase energy consumption.

2. Carefully monitor the water temperature of your pool in the summertime. You can reduce heat pump usage due to warmer air temperatures.

3. During the winter or when on vacation for longer than a week, turn off the heat pump.

4. Find the proper setting on the heat pump temperature control and use the Set Point Lockout or lock the cover on the heat pump controller to discourage further adjustments.

5. Set the pump time clock to start the pump no earlier than 6:00 AM during the pool heating season. This is the time when nightly heat loss balances.

6. Where possible, shelter the pool from prevailing winds with well-trimmed hedges or other landscaping, cabanas, or fencing.

7. Always use a pool cover when practical. Besides providing a valuable safety feature, a pool cover will reduce heat loss, conserve chemicals, and reduce the load on ﬁ lter systems.

1.3 Warranty

The EE-Ti heat pump is sold with a limited factory

warranty. Details are specified on the back cover of this manual.

Make all warranty claims to your Jandy dealer or

directly to Zodiac. Claims must include the heat pump serial number and model (this information can be found on the rating plate), installation date, and name of the installer. Shipping costs are not included in the warranty coverage.

The warranty does not cover damage caused by

improper assembly, installation, operation, winterizing, field modification, or failure to earth bond and properly ground the unit. Any changes to the heat pump, evaporator, heat exchanger, wiring, or improper installation may void the warranty.

1.4 Codes and Standards

The EE-Ti heat pump is listed by ETL as

complying with the latest edition of the “UL Standard for Safety for Heating and Cooling Equipment”, UL 1995 and CSA C22.2 No. 236.

Minimum Clearances for

Operation

Inches Centimeters Inches Centimeters

Recommended Clearances

for Serviceability

Access in front of the heat pump of 24” (60 cm)

provides adequate room for serviceability.

If the heat pump is to be installed in a garage or under a vertical overhang, the unit must have a minimum of 5 feet

(1.5 meters)

clearance from the top

of the heat pump.

In the U.S., the heat pump must be installed at least 5 feet (1.5 meters) from the inside wall of the pool or spa unless the heat pump is separated from the pool or spa by a 5 foot (1.5 meters) high solid fence or other permanent barrier.

Aux Etats-Unis, ce chauffe-piscine doit être installé á au moins 5 pieds (1,5 m) de la paroi interne de la piscine à moins d’être isolé de la piscine par une clôture, un mur ou autre barrière permanente.

En Estados Unidos, esta bomba de calor deberá instalarse a una distancia de al menos 5 pies (1,5 metros) de la pared interior de la piscina; a menos que la bomba de calentar esté separada de la piscina mediante una valla sólida de 5 pies (1,5 metros) de altura u otra barrera permanente.

Page 8

Jandy Heat Pump Models EE-Ti Installation and Maintenance Manual

In Canadian installations, the minimum distance to be maintained from the inside wall of the pool or spa is 3 meters (approx. 10 feet).

Pour les installations canadiennes, la distance minimale à maintenir du mur intérieur de la piscine ou du spa est de 3 mètres (approximativement 10 pieds).

2.2.3 Equipment Pad

Place the heat pump on a flat slightly pitched surface, such as a concrete or fabricated slab (pad). This allows proper drainage of condensation and rain water from the base of the unit. If possible, the pad should be placed at the same level or slightly higher than the filter system equipment pad.

NOTE Ensure that the pad is pitched not more than ¼

inch per foot cm per toward the compressor end (front) of the heat pump. Pitch slab from back to front ¼ inch per foot maximum and level from side to side.

2.2.4 Condensation and Drainage

Condensation will occur from the evaporator coil while the unit is running and drain at a steady rate, usually 3 to 5 gallons (11.4 to 18.9 liters) per hour, depending upon ambient air temperature and humidity. The more humid the ambient conditions, the more condensation will be produced. The bottom of the unit acts as a tray to catch rainwater and condensation. Keep the drain hole located on the right side of the base of the unit clear of debris.

If the heat pump is installed indoors, means of condensate disposal must be provided. The drain hole in the base of the heat pump is tapped to fit an optional 3/4” diameter barbed adapter, Jandy p/n R3004100 (see Section 9, “Replacement Parts”). If using the barbed adapter, connect a length of 3/4” tubing (5’ is included in Jandy p/n R3004100) to the adapter, then route it into a drain or outside the building to dispose of the condensate. It is important to remember that no part of

the tubing or hose may be above the level of the drain hole in the base of the heat pump.

2.2.5 Lawn Sprinklers

Keep lawn sprinkler heads from spraying on the heat pump to prevent corrosion and damage. Use a deflector if needed.

2.2.6 Roof Run-off

Make sure the heat pump is not located where large amounts of water may run-off from a roof into the unit. Sharp sloping roofs without gutters will allow massive amounts of rain water, mixed with debris from the roof to be forced through the unit. A gutter or down spout may be needed to protect the heat pump.

2.2.7 Installation of Anchor Clamps

In Florida, building codes require that the heat pump be anchored to the equipment pad or platform to withstand high wind pressures created during hurricanes. Other jurisdictions may have similar requirements. Please check your local codes for further details.

This heat pump is provided with anchor clamps designed to hold the unit to the equipment pad in high wind conditions. Installation of the anchor clamps is recommended in all installations and are required in Florida (reference Florida Building Code, Mechanical Section 301.13).

To install the anchor clamps:

1. Be sure that the heat pump is in its permanent

location on the equipment pad.

2. Remove the anchor clamps from the installation

and instruction package.

NOTE: Bolts and bolt anchors are not included with

the heat pump. Zodiac recommends that a 1/4” x 1½” long stainless steel Tapcon® type concrete screw is used to mount the clamp to the equipment pad. The Tapcon type concrete screw meets Florida building code requirements.

3. Place the clamps at the base of the heat pump in

the locations indicated in Figure 2.

NOTE: To install the brackets on the front of the heat

pump, the front cover must be loosened enough in order to place the bracket over the lip of the base. Be sure to re-tighten the front jacket panel to the heat pump.

4. Fit the hook of each clamp over the lip on the

3.1 Plumbing Layout

Figure 4 illustrates the standard plumbing layout with a single heat pump unit. Following the diagram from right to left, the plumbing sequence is as follows:

Pool > Pool Pump > Filter > Heat Pump > Check Valve > Chemical Loop > Chlorinator > Pool

NOTE For normal installations, do not install a shutoff

valve or any kind of variable restriction in the water piping between the heat pump outlet and the pool/spa.

Arrangement of pool system components other than as illustrated in the preceding and following diagrams can affect the operation of the heat pump’s water pressure switch. Location of the heat pump above or below the pool water surface can also affect operation of the switch. In general, the pressure switch can be adjusted to accommodate this effect if the heat pump water connections are no more than 5 feet below the pool water surface or no more than 11 feet above it. See instructions for pressure switch adjustment (Section

5.6) in the heat pump start-up section of this manual for more information. If the heat pump is installed outside of this range, an external flow switch may need to be installed in the plumbing upstream of the heat pump. Call the Zodiac technical support department at (800) 822-7933 for details.

Be advised that when pool equipment is located below the pool surface a leak can result in large scale water loss or flooding. Zodiac cannot be responsible for such water loss or flooding or the damage caused by either occurrence.

3.2 Water Connections at Heat Pump

Shipping plugs have been installed in the water inlet and outlet ports of the heat pump at the factory. Before installing any plumbing, remove the shipping plugs. Filtered water is plumbed to the inlet, located on

the right side of the heat pump front panel. Heated water flows through the outlet, located on the left side of the heat pump front. Two inch unions are provided.

Plastic piping (PVC Schedule 40) should be connected to the heat pump. The unions, provided with the unit, accept 2” PVC pipe.

CAUTION

Make sure that ﬂ ow requirements and pool water turn over rates can be maintained with the installation of additional heat pumps and plumbing restrictions.

ATTENTION

Assurez-vous que la circulation d’eau requise soit maintenue même si des pompes d’appoints ou des éléments de plomberie, causant des restrictions, sont ajoutés.

PRECAUCIÓN

Asegúrese de que los requerimientos de ﬂ ujo e índices de volumen de agua de la piscina puedan mantenerse, con la instalación de bombas de calentar adicionales y restricciones de fontanería.

3.3 Check Valve Installation

The heat pump must be protected from backsiphoning of water. If there is any chance of backsiphoning, provide a check valve between the pool and the filter pump inlet.

Page 10

Jandy Heat Pump Models EE-Ti Installation and Maintenance Manual

When an automatic chemical feeder is installed in the plumbing, it must be installed downstream of the heat pump. A check valve must be installed between the heat pump and the chemical feeder to prevent backsiphoning of chemically saturated water into the heat pump where it will damage the components.

3.4 Automatic Flow Control Valve

The inlet/outlet header of the EE-Ti heat pump comes equipped with an internal automatic flow control valve. The automatic flow control valve maintains the proper flow through the heat pump at rates up to approximately 125 gpm (475 lpm). If the filter system flow rate is higher than approximately 125 gpm (475 lpm), install a manual bypass valve (see Figure 4).

NOTE Be advised that if your circulation pump is over

2 HP or if the total ﬂ ow exceeds 125 gpm (475 lpm), you will have to add an external bypass valve.

3.5 Multiple Unit Installation

3.5.1 Heat Pump and Heater Combination

In certain regions of the country it may be more economical to run a heat pump during the warmer months and a gas heater during the cooler months.

In some situations it may be desirable to run the heat pump in the “Chiller” mode during the hottest portion of the year and a heater during the cooler months.

The Jandy heat pump may be plumbed with a gas or electric heater or any combination of heat sources including solar. All heat sources must be plumbed in parallel to work correctly and efficiently.

Figure 5 illustrates a recommended plumbing layout for a heat pump / heater / solar combination heating system for a pool / spa combination. Your system may not contain all of these components, but the basic plumbing will apply by eliminating the component in the illustration that is not a part of your system.

3.5.2 Multiple Heat Pump Connections

All plumbing on multiple heat pump installations must be done in parallel (see Figures 6 and 7). An equal flow of water to each heat pump is important for optimum operation.

NOTE It may be necessary to adjust water pressure

switch if a unit is installed below the water level. See Section 5.6 for details on when and how to adjust the pressure switch.

NOTE Each heat pump allows a maximum ﬂ ow rate of

125 gpm (475 lpm) and requires a minimum of 30 gpm (114 lpm).

Section 4. Electrical Connections

4.1 General Information

Wiring connections must be made exactly as shown in the wiring diagram found on the inside of the heat pump access compartment (see Figure 8 for single phase electrical wiring and Figure 9 for 3-phase electrical wiring). The heat pump must include a definite means of grounding and bonding. There is a bonding lug on the right side of the heat pump, where a bond wire must be attached.

5.1 Initial Start-up Precautions

Be sure that there is water in the pool and that the surface level is above the skimmer or other inlet of the pool’s filter system.

With any new pool or spa installation, operate the filter pump with the heat pump off long enough to completely clean the water. This will remove any installation residue from the water.

Clean the filter at the end of this operation before starting the heat pump. When raising the temperature of a cold pool, program the time clock to run the pump continuously.

This lets the filter system and heat pump operate continuously until the water reaches the temperature setting on the temperature control. When that happens, the heat pump will automatically shut off, but the filter pump will keep running.

5.2 Operating the Controller

Your new EE-Ti heat pump is controlled by an advanced microprocessor based controller that provides a sophisticated yet simple interface to operate your heat pump for maximum efficiency and enjoyment of your pool. To locate the control buttons, see Figure 15.

5.6 Water Pressure Switch Adjustment

CAUTION

The water pressure switch should be adjusted to turn the heater off when the pump is off. Setting the switch to close at too low of a ﬂ ow can damage the appliance. Adjust the switch to turn the heater off, not on.

ATTENTION

Le manocontact de pression d’eau doit être réglé de façon à ce que l’appareil cesse de fonctionner si la pompe s’arrête. Si le manocontact est réglé pour se fermer lorsque le débit d’eau est trop faible, l’appareil risque de s’endommager. Réglez le manocontact pour qu’il arrête l’appareil, et non pour qu’il le mette en marche.

all basic installations as shown previously in Section

3.1 and Section 3.5 in this manual. Only adjust the water pressure switch if the heat pump does not operate when the proper flow is applied to unit or if the heat pump does not shut off when the filter pump is off. Occasionally, unusual plumbing configurations or necessary restrictions in the plumbing may cause pressure sensing problems. In these rare situations, the plumbing system configuration may require adjustment of the water pressure switch.

Adjustment of the pressure switch may be necessary if any part of the filter system piping is 3 feet (1 m) or more above the top of the heat pump jacket.

Do not adjust the pressure switch if the heat pump is installed more than 11 feet (3.5 m) above or 5 feet (1.5 m) below the pool surface. Consult your local Jandy dealer for recommendations.

On some installations, the piping from the heat pump to the pool is very short. The back pressure could be too low to trigger the pressure switch. If this happens, it may be necessary to install a directional fitting or elbows where the return line enters the pool. This will increase back pressure enough for the heat pump to operate properly. If this configuration is necessary, be sure to check that the system flow is above the minimum requirement of 30 gpm (114 lpm) after the direction fitting or elbow has been installed.

Make sure the pool filter is clean before making any pressure switch adjustment: A dirty filter will restrict the water flow and the pressure switch cannot be adjusted properly.

To adjust the pressure switch:

1. Be sure that all valves in the system are set to

allow water ﬂ ow through the heat pump. Start the

ﬁ lter pump.

2. Set the heat pump control to call for heat. Set the

heat pump control to the POOL HEAT mode.

3. If the heat pump control displays “NO FLOW”,

then the ﬂ ow in the system may be below the

minimum ﬂ ow of 30 gpm (114 lpm) needed for

the safe operation of the heat pump. Investigate

and correct any ﬂ ow problems before adjusting the

water pressure switch.

PRECAUCIÓN

The pressure switch is preset at the factory for activation at 2 psi (14 kPa). This is the minimum setting for the water pressure switch and works for

4. Remove the heat pump’s control access panel. The water pressure switch is located in the lower left corner of the control compartment.

5. After conﬁ rming the ﬂ ow rate is at a minimum of 30 gpm (114 lpm), slowly rotate the thumb wheel on the water pressure switch in a counterclockwise direction until the “NO FLOW” indicator disappears from the control display. Remember that there is a time delay before the heat pump compressor will start.

6. Once the heat pump is running, turn off the ﬁ lter pump. The heat pump should turn off immediately.

7. If the heat pump continues to operate when the

Jandy Heat Pump Models EE-Ti Installation and Maintenance Manual

Page 23

ﬁ lter pump is off, turn the thumb wheel on the water pressure switch in a clockwise direction until “NO FLOW” is displayed on the control and the heat pump shuts down.

8. Check the setting of the water pressure switch by starting and stopping the ﬁ lter pump and checking the control display and operation of the heater between each ﬂ ow change.

9. If the water pressure switch cannot be adjusted to accommodate the conditions listed above, an external ﬂ ow switch must be added to the plumbing system to ensure that the heat pump will not operate without the proper ﬂ ow through the heat exchanger.

Section 6. General Maintenance

6.1 Water Chemistry

Proper chemical balances are necessary for

sanitary bathing conditions as well as ensuring your heat pump’s long life. Be sure to keep your chemical and mineral concentration levels within the values indicated in Table 3.

6.2 Winterizing

CAUTION

Failure to winterize could cause damage to the heat pump and will void the warranty.

ATTENTION

La garantie sera annulée si l’appareil n’est pas hivernisé convenablement.

PRECAUCIÓN

La falta de acondicionamiento de la bomba de calor para el invierno podía causar daños y anular la garantía.

In areas where freezing temperatures occur, you should protect your pump, filter, and heat pump from the elements. Perform the following steps to completely drain the heat pump (see Figure 16).

1. Turn off the electrical power to the heat pump at

the main breaker panel.

2. Shut off the water supply to the heat pump.

NOTE For spas, it is also necessary to perform water

changes in addition to chemical treatment. It is recommended to change the spa water every 60 days for light usage and every 30 days if usage is heavy.

4. Cover only the top of the heat pump to prevent debris from falling into the unit. Do not wrap the sides of the heat pump with any plastic or other material that will retain heat or moisture inside the unit.

6.3 Spring Start-Up

If your heat pump has been winterized, perform

the following steps when starting the system in the Spring:

1. Uncover the heat pump and inspect the top and sides for any debris or structural problems.

2. Connect the water inlet and outlet unions located on the lower front panel of the heat pump.

3. Turn on the ﬁ lter pump to supply water to the heat pump. Circulate water through the system long enough to cycle all of the pool water through the ﬁ lter. Check for leaks in and around the heat pump.

4. Check the pool chemistry and balance as necessary.

5. Turn on the electrical power to the heat pump at the main breaker panel.

6.4 Inspection and Service

Jandy heat pumps are designed and constructed

to provide long performance life when installed and operated properly under normal conditions. Periodic inspections are important to keep your heat pump running safely and efficiently through the years.

6.4.1 Owner Inspection

CAUTION

ATTENTION

PRECAUCIÓN

Zodiac recommends that you inspect your heat pump on a regular basis and especially after abnormal weather conditions. The following basic guidelines are suggested for your inspection:

1. Keep the top and surrounding areas of the heat

pump clear of all debris.

2. Keep all plants and shrubs trimmed and away from

the heat pump.

The heat pump will produce condensation (water) while in operation. The heat pump base is designed to allow the condensation to exit through the bottom drain port when the unit is running. The condensation will increase as the outdoor air humidity level increases. Check the following at regular intervals to ensure proper condensate drainage:

1. Visually inspect and clear the bottom drain ports

of any debris that could clog the ports.

2. Ensure that condensate water does not puddle

inside the heat pump

3. Ensure that condensate run-off is properly directed

away from the equipment pad to keep it from

undermining the pad.

During normal operation, the heat pump produces three to five gallons of condensate per hour. If condensate drainage is above this range during operation or if water continues to drain from the base when the heat pump is not in operation for more than an hour, a leak in the internal plumbing may have occurred. Call a qualified heat pump technician to investigate the problem.

Keep the top air flow discharge and air flow intake area clear of debris so the air flow though the heat pump is not restricted. The cooler discharge air from the top should not accumulate and be drawn into the side air intake coils. Keep all plants and shrubs trimmed away from the heat pump.

Make sure the front of the unit is accessible for future service.

Keep lawn sprinkler heads from spraying on the heat pump to prevent corrosion and damage. Use a deflector if needed.

If the unit is installed under a very sharp roof pitch or under a roof without a gutter, a gutter or diverter should be fitted to prevent excessive water from pouring down into the unit.

6.4.2 Professional Inspection

Inspections performed at least once a year by a qualified technician are required to maintain your heat pump’s safe and efficient operation. The following basic safety checks must be performed.

1 Check for loose or broken wires and terminal

connections.

2. Verify the pressure switch operation. Turn the heat

pump OFF. Disconnect the power to the pump

time clock, or turn the pump time clock to an OFF

position. Turn the heat pump back ON. The heat pump must not come on.

3. Inspect the electrical controls, speciﬁ cally the following:

a. High and Low limits b. Pressure switch c. Temperature control

4. Inspect the evaporator coil for blockage and clean as necessary.

5. Check for spider webs or debris in the condensate drain; clean if necessary.

6. Conduct a normal operating cycle and observe that the unit operates properly.

Section 7. Professional Maintenance and Service

7.1 Heat Pump Design

The Jandy heat pump is one of the most efficient

ways to heat a pool or spa. The heat pump transfers heat from the outside air to the pool or spa water by means of an internal heat exchanger.

When the fan is turned on, warm air is drawn

through the refrigerant charged evaporator, turning the cold liquid refrigerant to a warm gas. The gas then flows through the compressor where it is compressed resulting in a much higher temperature.

The hot gas enters the heat exchanger where the

water extracts the heat. The pump pulls in cool pool water, which in turn converts the hot gas back into a liquid refrigerant and starts the cycle over again.

The EE-Ti heat pump uses a refrigerant called

R-410A. It is a non-ozone depleting refrigerant that is accepted by the EPA. R-410A has higher operating pressures and cooling capabilities than R-22, which is the refrigerant used in the AE-Ti heat pump. Therefore, R-410A should NEVER be used in any of the AE-Ti heat pumps.

The EPA does not require certification to purchase

or use R-410A. It is recommended that service personnel be trained in installation, service, brazing, and maintenance procedures. They are similar to what the industry has used for the R-22 system, however, they should be redefined for the higher operating pressures.

NOTE The maximum heat output and efﬁ ciency of

a heat pump is dependent upon the quality and performance of the major components used. Equally important are the environmental conditions (for example, air temperature, humidity, water temperature, and wind).

7.2 Heat Pump Components and Operation

Evaporator - As air passes through the evaporator, the

refrigerant in the evaporator absorbs heat from the ambient air. The warmer the ambient air and the larger the surface area of the evaporator the more heat it can collect.

Fan - The heat pump fan produces high volume airﬂ ow.

Adequate airﬂ ow is required to move warm air through the large evaporator.

Compressor - The compressor compresses the

refrigerant gas to a higher pressure, increasing the temperature.

Heat Exchanger - As the ﬁ nal step to the heating

process, the heat exchanger transfers the heat from the hot gas to the water. (Also known as a condenser.)

Reversing Valve - (For Hybrid Units with Optional

Chiller and Hot Gas Defrost) The reversing valve reverses the ﬂ ow of the refrigerant, which results in transferring cold gas to the water, thus lowering the temperature.

8.1 Troubleshooting Guide

The following table provides symptoms and solutions for general troubleshouting problems for the heat pump.

Table 4. Heat Pump Troubleshouting Guide

SYMPTOM CORRECTIVE ACTION

Heat pump will not start, no control board display. Breaker or fuse may be tripped. Reset breaker or check fuse. If

heat pump still does not run, call for service.

Three-phase models only - The phases may be reversed or there may be a loss of phase, call for service.

Heat pump will not start, control board display working. Heat pump may be in delay count down of 5 minutes. Make

sure control board thermostat is calling for heater to come on (check setting on thermostat and temperature reading). Make sure heat pump is not in cooling mode.

Heat pump runs but does not heat. Verify cold air is blowing out the top of the heat pump. If the

heat pump has just been installed or if the pool water has been allowed to cool significantly, it is necessary to run the heat pump continually for 24-48 hours. If the heat pump has been in operation for some time, increase the circulating pump time, or switch the control board to Maintain Heat function. If heating a spa, verify no air intake stand pipes are open. If heat pump still does not heat, call for service.

Verify circulating pump is on and all necessary valves are in the correct positions. Verify filter and skimmers are clean. Check water level in pool. Temporarily turn off all fountains and water falls that bypass the heat pump water inlet. If this does not correct the problem, call for service.

Verify circulating pump is on and that there are no water flow restrictions to the heat pump. Make sure all necessary valves are open or in the proper positions to allow proper water flow to the heat pump. Verify filter and skimmers are clean. Check for water level in the pool. This condition may also appear if the heat pump has not been operated for an extended period. To clear the condition, cycle the heat pump, on and off, up to 3 times. If this does not correct the problem, call for service.

Check that fan is operating and air is coming out of the top of the heat pump, while short cycling. If heat pump does not run at all, call for service.

Low or restricted water flow through the heat pump.

The external bypass valve is in the wrong position, or the water flow switch has malfunctioned. The water flow switch opens creating a fault and the heat pump shuts off.

When the ambient temperature is low, the suction pressure can drop significantly.

This fault will cause the low pressure switch to open and the control will shut off the compressor.

When the head pressure builds too high, the high pressure switch will open causing the heat pump to shut off immediately.

The control will sense this fault condition and shut off the compressor until the switch re-closes.

When the POOL or SPA water temperature heats to the maximum allowed temperature or above, there could be safety risks for anyone in the water.

The water thermostat will read this temperature and the control will shut off the heat pump unless it is in CHILLER mode.

This feature also remains active when the control calls for heat through a remote thermostat. This is to insure that water temperature does not go to an abnormally high level due to a possible malfunction of the remote sensor.

In the event that the coil temperature sensor malfunctions or is not connected the control will shut off the heat pump.
