Heat Pump 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 transferring it into the water. The warmer the air and the more humidity in 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 (-17°C) per hour depending on air temperature, humidity, and water temperature. The ideal or rated condition for the heat pump is 80°F (27°C) air temperature, 80% relative humidity, and 80°F (27°C) 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 sun’s energy, operate your heat pump during the heat of the day.
Your heat pump will still operate when the temperature drops 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 since it may take the heat pump days to heat your pool back to your desired temperature, depending on your pool temperature and environmental conditions.
Heat Pump Installation Requirements

INSTALLATION AND LOCATION

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 property or 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.

Only a qualified service person should install the UltraTemp® Heat Pump. Before installing this product, refer to IMPORTANT SAFETY INSTRUCTIONS on page i.
Materials Required for Installation
The following items are needed and are to be supplied by the installer for all heat pump installations:
1. Plumbing connections (2-inch).
2. Level surface for proper drainage.
3. Suitable electrical supply line. See rating plate on unit for electrical specifications. A junction box is not needed at the heat pump; connections are made inside of the heat pump electrical compartment. Conduit may be attached directly to the heat pump jacket.
4. Electric cutout switch that will interrupt all power to the unit. This switch must be within line of sight of the heat pump. Check local codes for requirements.
5. Watertight conduit to run the electrical supply line.
Equipment Pad
For proper drainage of condensation and rain water, place the heat pump on a flat slightly pitched surface, such as a concrete or fabricated slab (pad).
If possible, place the pad at the same level or slightly higher than the filter system equipment pad.
Note: Be sure that the pad is pitched not more than 1/4 in. per foot in any direction as needed for runoff.

Drainage and Condensation
Condensation occurs from the evaporator coil while the unit is running, and drains 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.
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.
Lawn Sprinklers
Avoid placing lawn sprinkler near the heater they can spray water into the heater and void the warranty.
Be sure to direct any spraying water away from the heater. Note the wind direction to be sure water from sprinklers is not blown toward the heater. Sprinkler heads can produce high water pressure and spray at an angle, different from typical rain and humid weather. Also, sprinklers connected to a well water system can cause mineral build up on the evaporator coils and electronics. Salt water can also be an issue if located near the coast.

Water Connections and Plumbing
The image below shows the standard plumbing layout with a single UltraTemp® Heat Pump. Follow the image from right to left for the standard plumbing sequence. Arrangement of pool system components (other than the standard plumbing image below), and the location of the heat pump (above or below the pool water surface) can affect the operation of the heat pump’s water pressure switch. The pressure switch can be adjusted to accommodate this effect if the heat pump water connections are no more than six (6) feet [1.8 m] below the pool water surface.
See instructions for pressure switch adjustment on page 6. 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. Note: Be advised that when pool equipment is located below the pool surface a leak can result in large-scale water loss or flooding. Pentair is not responsible for such water loss or flooding or damage.
Automatic Flow Control Valve
The inlet/outlet header of the 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 120 gpm (456 lpm). If the filter system flow rate is higher than 120 gpm (456 lpm), install a manual bypass valve, see image below.
Note: Be advised that if your circulation pump is over 2 HP or if the total flow exceeds 120 gpm (456 lpm), you will have to add an external bypass valve. Excess water flow will damage the heat exchanger.

Water Pressure Switch Adjustment
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 pressure switch is preset at the factory for activation at 1.5 psi [10 kPa]. This factory setting works for most basic installations. 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 [0.9 m] or more above the top of the heat pump.
In general, if the heat pump is installed more than 6 feet [1.8 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, install a directional fitting or elbow where the return line enters the pool. This will increase back pressure for the heat pump to operate properly. Be sure to check that the system flow is above the minimum requirement of 30 gpm (110 lpm) after the directional fitting installation.
Be 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 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 “LOW WATER FLOW” Alarm shows on the LCD, the red SERVICE light 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 light is present then the water pressure switch needs to be adjusted.
4. Remove the UltraTemp® 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 light 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 light 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.

Multiple Unit Installation

1. Heat Pump, Heater and/or Solar Combination
In certain regions of the country it may be more economical to run a UltraTemp® 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 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.

2. Multiple Heat Pump Connections
All plumbing on multiple heat pump installations must be done in parallel (see next page). An equal flow of water to each heat pump is important for optimum operation.
Note: It may be necessary to adjust the water pressure switch if a unit is installed below the water level. Refer back to page 6 for details on when and how to adjust the pressure switch.
Each heat pump in a multiple unit installation allows a maximum flow rate of 100 gpm (380 lpm) and requires a minimum of 30 gpm (110 lpm).

A recommended plumbing layout for a heat pump / heater / solar combination heating system for a pool / spa combination is shown below. 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.

OPERATING THE HEAT PUMP

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 – INITIAL START UP PRECAUTIONS
After the water pressure switch is activated there is a one minute temperature sensing delay then if there is a call for heat or cool the fan will turn on and there will be an additional 5 minute delay for the compressor to start. 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.

Swimming Pool Energy Saving Tips
It is important to note that an UltraTemp® 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 water temperature at or near the desired temperature. For extended non-use, turn the heat pump completely off or decrease the 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 performance.
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.

Heartbeat Indicator

AutoSet
Heat pumps manufactured after 5/9/22 are not equipped with the AutoSet feature. The AutoSet Accessory Kit (P/N 473603z) may be purchased separately.
The AutoSet feature periodically energizes a contactor connected to a filter pump. This allows the heat pump to start and stop the filter pump independent of the time clock, allowing the heat pump to circulate water and sense water temperature. Enable this feature any time the filter pump is off.
When the temperature is not as desired, the heat pump will start and run until the water reaches the desired temperature. The filter pump and heat pump will then stop.
AutoSet allows you to set the time interval between the end of the circulation cycle and when the heat pump reactivates the filter pump to sense the water temperature.
To enable the AutoSet feature: 1. Ensure the filtration pump is wired in parallel with a
mechanical time clock, using the auxiliary relay supplied in the high voltage power panel of the heat pump.
2. Press the MENU SELECT button repeatedly until the AutoSet screen is displayed.
3. Press the UP or DOWN arrows to toggle between ON and OFF.

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 on the sides 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 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 can void the warranty.

Winterizing
Failure to properly winterize could damage equipment and will void the warranty. Ensure both the inlet and outlet union are completely disconnected from the heat pump and that plumbing connections are positioned so that all water can freely drain from the heat pump.
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.
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 opposite sides of the heat pump.
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.

Owner Inspection
Pentair 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.
5. If the unit is installed under a roof edge, install a gutter or diverter to prevent excessive water and debris 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. Be sure the condensate run-off is properly directed away from the equipment pad to keep it from undermining the pad.
4. Be sure the condensate water does not puddle inside the heat pump. To be sure it is condensate water, check for the absence of chlorine.
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.
ULTRATEMP® Heat Pump Installation and User’s Guide

Professional Maintenance and Service
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. Compressed air can also damage the heat pump coil. DO NOT USE A PRESSURE CLEANER ON THE UNIT.
The heat pump should be maintained at least once a year by qualified personnel to maintain maximum performance and efficiency. The unit should be powered off during maintenance.

Problems or Symptoms HIGH REFRIG Alarm: Refrigerant high pressure switch is open.
LOW REFRIG Alarm: Refrigerant low pressure switch is open.

Possible Cause

Corrective Action

Water circulation pump inactive.

Verify water pump is on.

Insufficient water flow.

Verify filter and skimmers are clean, backwash if necessary. Minimum flow 30 GPM [113.6 LPM].

External bypass open.

Verify external water bypass around heat pump is closed. Also make sure all other valves are open or in the proper positions to allow proper water flow through heat pump.

Bad refrigerant high pressure switch.

Check resistance of switch, if open, replace switch.

TXV Stuck Closed.

1. Disconnect TXV bulb from suction line (SL), have it in your hand, if pressures go back to normal, then reinstall the bulb on suction line (it may have some debris stuck in the port). For adjustable TXVs open adjustable valve, it may remove the debris and set it back to original position.
2. If (1) does not work, recover the charge, remove bulb from SL, unscrew TXV head, shake it, if rattles, replace head (PN KT-45-ZGA), if not, replace TXV and filter dryer and charge appropriately.

Other Possibilities:

Check Water level in pool. This condition may appear if the heat pump has NOT been operated for an extended period. To Clear this condition, cycle the heat pump on and off up to 3 times. If this does not correct problem, call for service.

Other Possibilities. Low or restricted water flow through heater. Dirty or worn filters or clogged lint traps. Clogged filter pump impeller. Improper plumbing valve settings. Suction leak allowing air into the water flow. Low water flow when switched to spa mode. Unit is plumbed backwards. Heat exchanger clogged with debris. Internal bypass valve damaged or clogged with debris.

Clean entire filtering system and or replace filter element. Inspect & clean pump impeller. Adjust all plumbing valves. Repair suction air leaks, grease pump lid O-ring. Replace filter. Wrong filter pump pipe size. Automatic pool vacuum causing restriction. Call your dealer or factory for advice if above does not solve the problem.

Unit overcharged.

Reclaim charge. Recharge with appropriate nameplate charge.

Compressor Thermal Protector tripped open.

Check Thermal Protector located on top of the compressor. The Thermal Protector will trip if the compressor reaches a temperature greater than 240°F (115.6°C). It will reset when the temperature drops below 170°F (76.7°C). If the corrective actions above do not resolve the HIGH REFRIG Alarm, check the resistance of the Thermal Protector while the unit is powered off, if the circuit is open, replace the Thermal Protector.

*This feature is only available on heat pumps equipped with LG compressors starting 11/1/2020, except the UT70 model, which uses an internal Thermal Protection device.

Low refrigerant in system.

Find source of refrigerant leak and fix. Pull vacuum and recharge.

Air and water temperatures too cold to operate the heat pump.

Wait until temperatures warm up and see if unit operates.

Bad refrigerant low pressure switch.

Check resistance of switch with a full charge, if open, replace switch.

Faulty fan.

Check the capacitor and fan motor. Replace either one if it is faulty. Check the fan blade and make sure it is not slipping or broken. If so, replace the fan.

TXV Stuck Closed.

1. Disconnect TXV bulb from suction line (SL), have it in your hand, if pressures go back to normal, then reinstall the bulb on suction line (it may have some debris stuck in the port). For adjustable TXVs open adjustable valve, it may remove the debris and set it back to original position.
2. If (1) does not work, recover the charge, remove bulb from SL, unscrew TXV head, shake it, if rattles, replace head (PN KT-45-ZGA), if not, replace TXV and filter dryer and charge appropriately.
