Consumer Information and Safety

The UltraTemp® series of heat pumps are designed and manufactured to provide 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 “ “ symbol. Be sure to read and comply with all of the warnings and cautions.

WARNING —

1. Spa or hot tub 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. Prolonged immersion in hot water can induce hyperthermia.

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 above 100° F. [38° C.] can cause fetal damage during the first three months of pregnancy (which may result 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, the user should check the water temperature with an accurate thermometer. Spa or hot tub thermostats may err in regulating water temperatures.

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

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

Hyperthermia occurs when the internal temperature of the body reaches a level several degrees above normal body temperature of 98.6° F. [37° C.]. The symptoms of hyperthermia include: drowsiness, lethargy, dizziness, fainting, and an increase in the internal temperature of the body.

The U.S. Consumer Product Safety Commission warns that elevated water temperature can be hazardous. See below for water temperature guidelines before setting temperature.

The following “Safety Rules for Hot Tubs” recommended by the U.S. Consumer Product Safety Commission should be observed when using the spa.

The effects of hyperthermia include:

1. Unawareness of impending danger.

2. Failure to perceive heat.

3. Failure to recognize the need to leave the spa.

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 use your pool for a prolonged period, then you might choose to turn the heat pump completely off temperature setting of the control several degrees to minimize energy consumption.

Pentair 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 significantly 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 Keypad Lock function to discourage further

adjustments.

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

fencing.

6. Pentair recommends the use of a pool cover. Besides providing a valuable safety feature, a pool cover will reduce heat

loss, conserve chemicals, and reduce the load on filter systems.

Section 1

Introduction

Overview

Your Pentair heat pump will provide you with years of heated pool enjoyment. Heat pumps operate by taking heat from the surrounding air and transfering it into the water. The warmer the air and the more humid the air, the more latent heat is available for heating your pool. With a properly sized heat pump for your pool, the heat pump should raise your pool on average 1° F. per hour depending on air temperature, humidity, and water temperature. The ideal or rated condition for the heat pump is 80° F. air temperature, 80% relative humidity, and 80° F. water temperature. As conditions decrease from 80/80/80, the heat pump performance will decrease slightly.

Heat Pumps are best utilized to maintain a set water temperature; they are not intended to provide instant or fast heating. It is not reasonable to expect a heat pump to perform like a gas heater which has a much higher BTU output and faster response. Additionally, gas heaters are not dependent on environmental conditions. Swimming pool heat pumps are very similar to home heating and air conditioning heat pumps and therefore should be treated similarly.

Proper operation and use of the heat pump is to set it at your desired temperature and leave it. Your heat pump will turn on and off automatically to maintain your desired temperature much like your home HVAC unit. To take advantage of the suns energy operate your heat pump during the heat of the day. Your heat pump will still operate when the temperature dips at night, but the output will be decreased.

It is acceptable to shut the heat pump off and not use it for extended periods of time. When you have a need to heat your pool, please plan accordingly because it may take the heat pump days to heat your pool back up to your desired temperature depending on your pool temperature and environmental conditions.

Correct installation is required to assure safe operation. The requirements for Pentair Water heat pumps include the following:

• Dimensions for critical connections.

• Field assembly (if required).

• Appropriate site location and clearances. (See pages 4-5.)

• Proper electrical wiring. (See pages vi and 11, 32-34.)

• Adequate water flow. (See page vi.)

This manual provides the information needed to meet these requirements. Review all application and installation procedures completely before continuing the installation.

Location

CAUTION —

When pool equipment is located below the pool surface, a leak from any component can cause large scale water loss or flooding. Pentair Water Pool and Spa, Inc. cannot be responsible for such water loss or flooding which may cause damage to the product.

Avoid placing the heat pump in locations where it can cause damage by water or condensate leakage. If this is not possible, provide a suitable drain pan to catch and divert any leakage.

Installation and User’s Guide

Page 13

Clearances

All criteria given in the following sections reflect minimum clearances. However, each installation must also be evaluated, taking into account the prevailing local conditions such as proximity and height of walls, and proximity to public access areas.

The heat pump must be placed to provide clearances on all sides for maintenance and inspection.

1. At least 24 in. [61cm] access must be available in the front and 24 in. [61 cm] on all the other sides of

the heat pump for service and proper air flow, see Figure 2.

2. If the heat pump is to be installed under a cover or under a vertical overhang, the unit must have a minimum

of six (6) feet [1.83 m] clearance from the top of the heat pump.

3. Install a minimum of five (5) feet [1.52 m] from the inside wall of the pool or spa unless the heat pump

is separated from the pool or spa by a five (5) foot high solid fence or other permanent barrier. Canadian installations require a minimum of three (3) meters from pool water.

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, see Figure 2. A gutter or down spout may be needed to protect the heat pump.

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 1/4 in. per foot toward the compressor end (front) of the heat pump. Pitch slab from back to front 1/4 in. per foot maximum and level from side to side.

Installation and User’s Guide

Page 14

NO SPRINKLERS

Drainage and Condensation

Condensation will occur from the evaporator coil while the unit is running and drain at a steady rate, usually three to five gallons 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 holes, located on the bottom pan of the base of the unit, clear of debris.

Lawn Sprinklers

NO SPRINKLERS

Make sure there are absolutely no sprinkler heads near the heater that will in any way spray on or into the heater. Sprinkler damage is not covered under

the warranty agreement.

Make sure that they’re a sufficient distance away so that normal winds will not carry the mist to the heater. If your filtering system area has plants that need water, use a trickle type irrigation sprinkler instead of the broadcast type.

NO SPRINKLERS

rain and humidity, etc. Sprinkler heads force high pressure water into the unit from the side at an odd angle. Most sprinkler systems are connected to a well system. Most well water is high in minerals, sulphur and other aggressive contaminates. These contaminates will leave a build up on the evaporator coils and electronics causing corrosion and hamper the efficiency. If you are located within 15 miles of the coast, salt may also be in the well water.

Anchor Clamp(s) Installation

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.

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. Installation of the anchor clamps is required in Florida (See Florida Building Code 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. The installer must provide 1/4” x 1-3/8” stainless steel anchor bolts and the appropriate size concrete anchor to mount the clamp to the equipment pad.

3. Place the clamps at the base of the heat pump in the 4 locations indicated in Figure 4, (2 in. undercut [notched area] on either side).

4. Fit the hook of each clamp over the lip on the base panel of the heat pump. The hook should fit between the lip of the base panel and the evaporator coil guard, see Figure 5.

5. Mark the position of the hole in each clamp on the equipment pad.

The heat pump must be protected from back-siphoning of water. If there is any chance of back-siphoning, provide an optional manual bypass valve between the pool and the heat pump outlet. Arrangement of pool system components other than as illustrated in Figure 6 and the 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 six (6) feet below the pool water surface or no more than fifteen (15) feet above it. See instructions for pressure switch adjustment (page 16) 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 pressure switch may need to be installed in the plumbing upstream of the heat pump. Call the Pentair Water Heat Pump Technical Service department at (800) 831-7133 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. Pentair cannot be responsible for such water loss or flooding or the damage caused by either occurrence.

Heat Pump, Heater and/or Solar 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, if so equipped, during the hottest portion of the year and a heater during the cooler months. The Pentair Water heat pump may be used in conjunction with a gas or electric heater or any combination of heat sources including solar. All heat sources must be plumbed in series to work correctly and efficiently.

A recommended plumbing layout for a heat pump / heater / solar combination heating system for a pool / spa combination is shown in will apply by eliminating the component in the illustration that is not a part of your system.

Water Pressure Switch Adjustment

CAUTION —

The pressure switch is preset at the factory for activation at 1.5 psi [10 kPa]. This factory setting works for most basic installations as shown previously on pages 7, 9-10 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 [0.91 m] or more above the top of the heat pump.

In general, if the heat pump is installed more than 6 feet [1.83 m] below the pool surface, an external water flow switch must be added to the plumbing system.

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 (110 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:

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 flow can damage the appliance. Adjust the switch to turn the heater off, not on.

The following adjustment is for installations where the heat pump is below pool water level.

1. Be sure that all valves in the system are set to allow water flow through the heat pump. Start the filter pump.

2. Set the heat pump temperature above the actual temperature to call for heat. Turn the heat Pump ON.

3. Once the heat pump is running, turn off the filter pump. The heat pump should turn off immediately.

4. If the heat pump continues to operate when the filter pump is off, then the water pressure switch needs to be adjusted.

5. Remove the heat pump’s left front panel and remove remaining right front panel. The water pressure switch is located in the water plumbing in the lower right corner of the heat pump.

6. Slowly rotate the adjustment wheel on the water pressure switch in a clockwise direction until the the “LOW WATER FLOW” Alarm shows on the LCD, the Red Service LED turns ON, and the heat pump stops.

7. Check the setting of the water pressure switch by starting and stopping the filter pump and checking the control panel and operation of the heater between each flow change.

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

The following adjustment is for installations where the heat pump is above pool water level.

1. Be sure that all valves in the system are set to allow water flow through the heat pump. Start the filter pump.

2. Set the heat pump temperature above the actual temperature to call for heat. Turn the heat Pump ON.

3. If the LCD shows a “LOW WATER FLOW” Alarm and Red Service LED is present then the water pressure switch needs to be adjusted.

4. Remove the heat pump’s left front panel and remove remaining right front panel. The water pressure switch is located in the water plumbing in the lower right corner of the heat pump.

5. Slowly rotate the adjustment wheel on the water pressure switch in a counterclockwise direction until the “LOW WATER FLOW” Alarm and Red Service LED vanish, time delay countdown will start.

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

7. If the heat pump continues to operate when the filter pump is off, turn the adjustment wheel on the water pressure switch in a clockwise direction until the “LOW WATER FLOW” Alarm shows on the LCD, the Red Service LED turns ON, and the heat pump stops.

8. Check the setting of the water pressure switch by starting and stopping the filter pump and checking the control panel and operation of the heater between each flow change.

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

Section 3

Operating the Heat Pump

This section describes how to operate the heat pump.

Initial Start-up Precautions

CAUTION —

After starting the heat pump, please note that there is a 5 minute delay before the compressor begins operation. The heat pump display will show the remaining delay time in minutes and seconds.

Do not use this heat pump if any part has been under water. Immediately call a qualified service technician to inspect the heater and replace any part of the control system which has been under water.

Keep all objects off the top of the heat pump. Blocking air flow could damage the unit and may void the warranty.

ATTENTION

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

The pool pump must be on and water flowing through the heat pump for it to operate.

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.

communications link with a Pentair automation controller. When operating in this mode, the heat pump's local set point is disregarded. The heat pump will heat or cool as told by the automation controller without regard to the local set point. However, the high and low temperature faults are still active so the heat pump will not heat above 104° F. or cool below 45° F. To use the Serial Remote mode, the Serial Remote should be turned ON (default setting) and, the Intell Address screen from the Operator Setup Menu Tree must be assigned to the proper address. One (1) is the most commonly used address.

9. AutoSet Operation – The AutoSet feature periodically energizes a contactor which can be connected to the pump to move water though the heat pump. This allows the heat pump to sense the temperature of the body of water whose temperature is being maintained. After a temperature stabilization delay, the heat pump will determine if it needs to start or not. If the temperature is at the desired level, the heat pump does not start and the filter pump contactor is de-energized. If the water temperature is not at the desired level, the heat pump starts and will run, along with the filter pump, until the water reaches the desired temperature. At that point the filter pump and the heat pump will stop. (See AutoSet on

page 8 for further details/example.)

• To activate the control panel lockout, press the MENU SELECT and POOL/SPA buttons simultaneously.

• To unlock the control panel, press the MENU SELECT and POOL/SPA buttons simultaneously.

DEFROST CYCLE

At air temperatures around 50° F, the heat pump may enter a defrost cycle. The defrost cycle is initiated when a sensor on the evaporator detects that the refrigerant temperature has fallen below the defrost set point. At this time, the heat pump compressor will stop. The heat pump evaporator fan will continue to run, and will draw air over the evaporator fins for about 15 minutes. If, at the end of the 15 minutes, the temperature sensor detects a temperature above 44° F, the compressor will restart. Otherwise the unit will shut down.

Because a heat pump's efficiency decreases as air temperature decreases, it is preferable to operate the heat pump during the warmest time of day. As a rule, the unit should not be operated during the coolest time of day, or when the air temperature falls below 45° F.

Installation and User’s Guide

AUTOSET

Autoset is a feature that allows the heat pump to automatically turn on your water circulation pump at predetermined time intervals after the water circulation pump shuts off. To utilize this feature, the water circulation pump must be wired in parallel with your mechanical time clock using the auxiliary relay supplied in the high voltage power panel of the heat pump.

For example, if your pool water circulation pump is wired properly with the time clock through the heat pump, have the heat pump control board programmed with a pump start time interval of 4 hours, have the AutoSet feature enabled, and you wish to maintain your pool to 80° F., this is the sequence of events that will happen.

1. If your mechanical time clock is set to shut off at 9:00 p.m., once the water circulation pump shuts off, the heat pump will display a countdown window.

PUMP START DELAY

REMAINING=4:00

2. The heat pump will continue to countdown in hours and minutes.

3. Once the 4 hours has expired, at 1:00 am, the control board will energize the internal contactor in the heat pump to turn on your water circulation pump.

4. The heat pump will sense water temperature then determine if it needs to continue to circulate water. If the pool temperature has fallen below your set point, 80 degrees for this example, the heat pump will turn on and begin heating the pool. Once the pool temperature has reached its set point, 80 degrees, the heat pump will shut off and will also shut off the water circulation pump.

5. If after the water sensing time, the heat pump detects the pool water is above the set point, 80 degrees for this example, it will shut off and shut the water circulation pump off also.

6. At the time the water circulation pump shuts off, the heat pump will again reset and begin the countdown interval again and display the following window.

PUMP START DELAY

REMAINING=4:00

7. The heat pump will continue this cycle every time the water circulation pump is shut off.

8. Once the time clock turns on in the morning, the heat pump will stop the AutoSet feature and resume normal operation.

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.

Winterizing

CAUTION —

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

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 22.

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.

3. Disconnect the water inlet and outlet unions located on the lower front panel of the heat pump.

4. Blow out the water lines.

5. 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.

Installation and User’s Guide

Water Outlet Union

Water Inlet Union

Figure 22.

Page 45

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 filter pump to supply water to the heat pump. Open the filter air bleeder and circulate water

through the system long enough to bleed all the air out of the pool system. Check for leaks in and around the heat pump.

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

Inspection and Service

Pentair Water 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. Failure to properly maintain your unit may void your warranty.

Owner Inspection

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

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

2. Keep the top and surrounding areas of the heat pump clear of all debris.

3. Keep all plants and shrubs trimmed and away from the heat pump.

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

if needed.

5. 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. Do not use this heat pump if any part has been under water. Immediately call a qualified professional

technician to inspect the heat pump and replace any part of the control system which has been submerged.

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. 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.

3. Ensure that condensate run-off is properly directed away from the equipment pad to keep it from

undermining the pad.

4. Ensure that condensate water does not puddle inside the heat pump.

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.

Installation and User’s Guide

Page 46

Professional Maintenance and Service

The Pentair line of Heat Pumps are some 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 R410A refrigerant charged air coil, turning the cold liquid refrigerant to a warm gas. The gas then flows through the compressor, which increases the pressure and refrigerant temperature. The hot refrigerant gas enters the water-to-gas heat exchanger where the water is heated and returned to the pool. During this heat exchange process the refrigerant is cooled and returned to the air coil and the cycle repeats.

NOTE: The maximum heat output and efficiency 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). To maintain maximum performance and efficiency, keep the air coil clean from dirt and debris. It is recommended to clean your air coil once a year by flushing the coil with compressed air or hosing off the coil with a garden hose. Care should be taken to not bend the coil fins as this will restrict the airflow and lower your heat pump performance. DO NOT USE A PRESSURE CLEANER ON

THE UNIT.

Troubleshooting

Use the following troubleshooting information to resolve possible problems with your heat pump.

WARNING —

RISK OF ELECTRICAL SHOCK OR ELECTROCUTION.

Improperly installation will create an electrical hazard which could result in death or serious injury to pool users, installers, or others due to electrical shock, and may also cause damage to property. Do NOT attempt any internal adjustments inside the heater.

1. Keep your hands and hair clear of the fan blades to avoid injury.

2. If you are not familiar with your pool filtering system and heater: a. Do NOT attempt to adjust or service without consulting your dealer, professional pool or air

conditioning contractor.

b. Read the entire Installation & User’s Guide before attempting to use, service or adjust the

heater or pool filtering system. 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 flow can damage the appliance. Adjust the switch to turn the heater off, not on.
