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 follow 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 effects of hyperthermia include:

1. Unawareness of impending danger.

2. Failure to perceive heat.

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

4. Physical inability to exit the spa.

5. Fetal damage in pregnant women.

6. Unconsciousness resulting in danger of drowning.

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 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. Also, 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.

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 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 heat
pump. Before installing this product, refer to the
Important Warning and Safety Instructions on page ii.

Materials Needed 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.

extreme weather (i.e. hurricanes).

To install the anchor clamps:

1. Be sure the heat pump is in its permanent location
on the equipment pad.

2. Place the clamps at the base of the heat pump in
the four (4) locations, shown in the image below.

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. Be sure to check local codes.

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

Water Connections and Plumbing

The image below shows the standard plumbing layout
with a single heat pump unit. Follow the image below

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.

Location of the heat pump above or below the pool water
surface can also affect operation of the switch.

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.

See instructions for pressure switch adjustment on the
next page. 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ltersystemowrateishigherthan

Water Pressure Switch Adjustment

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lter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.

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.

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 fi lter is clean before making any
pressure switch adjustment: A dirty fi lter will restrict
the water fl ow and the pressure switch cannot be
adjusted properly.

Adjusting 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 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

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 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 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.

2. Multiple Heat Pump Connections

All plumbing on multiple heat pump installations must be
done in parallel (see image below). 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 5 for details on when and how to adjust
the pressure switch.

Each heat pump allows a maximum fl ow rate of
100 gpm (380 lpm) and requires a minimum of 30
gpm (110 lpm).

Electrical Connections and Wiring

RISK OF ELECTRICAL SHOCK OR ELECTROCUTION.

This heat pump contains wiring that carries high voltage. Contact with these wires could result in death or serious injury to pool or
spa users, installers, or others due to electrical shock, and may also cause damage to property. Always disconnect power circuit
before connecting the heat pump

Label all wires prior to disconnection when servicing controls. Wiring errors can cause improper and dangerous operation. Verify
proper operation after servicing.

General Information

Wiring connections must be made exactly as shown
in the wiring diagram found on the inside of the heat
pump access panel; see the wiring diagrams on
pages 9-11.

The heat pump must include a definite means of
grounding and bonding. There is a ground lug inside
the heat pump electrical compartment and a bonding
lug on the left side of the heat pump.

Bonding

The National Electrical Code and most other codes
require that all metallic components of a pool structure,
including reinforcing steel, metal fittings, and above
ground equipment be bonded together with a solid
copper conductor not smaller than 8 AWG. The heat
pump, along with pumps and other pool equipment
must be connected to this bonding grid. A bonding lug
is provided on the left side of the heat pump to ensure
this requirement is met.

This heater must be connected to a bonding grid
with a solid copper wire not smaller in diameter
than 8 ga.

Main Power

Electrical wiring to the heat pump must be in
accordance with the latest edition of the National
Electric Code (NEC), ANSI/National Fire Protection
Association (NFPA) 70 in the United States, and in
Canada, the Canadian Electrical Code (CEC) C22.1,
unless local code requirements indicate otherwise.
All wiring must be done by a certified or qualified
electrician.

Be sure the power to the circuit for the heat pump
is turned off.

The following is the procedure to wire the heat pump
to the electrical source:

1. Remove the front left panel of the heat pump
cabinet, (you do not need to remove the torque
head screw at the top left corner).

2. Remove the service panel to the heat pump
electrical compartment. (Front left corner of unit)

3. Electrical supply lines must be run through
watertight conduit. Run the wires and conduit from
the power source and connect them to the conduit
connection on the left side of the heat pump.

4. Connect the power leads to the bottom terminals
on the main compressor contactor as shown in
the wiring diagrams on pages 9-11.

5. Verify that all other contactor wires are secure;
they may have loosened during shipment.

6. Connectthegroundwiretothegroundlug

provided on the bottom of the electrical
compartment.

7. Replace the service panel and reinstall screws to
hold it in place.

8. Replace the front left panel.

9. Connect a copper bonding wire (8 AWG) to the
bonding lug on the left side of the heat pump.

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 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
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 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.

detects refrigerant temperature below the defrost set
point. At this time, the heat pump compressor stops.
The heat pump evaporator fan will continue to run,
and will draw air over the evaporator fins for about 15
minutes.

If the temperature sensor detects a temperature above
44° F (7° C), the compressor will restart after the 15
minutes. If not, the unit will shut down.

The efficiency of a heat pump decreases as air
temperature decreases. For maximum efficiency,
operate the heat pump during the warmest time of day.

Serial Remote (RS485 Cable)

See IntelliTouch/EasyTouch user’s manual for additional
setup instructions.

In serial remote operation, the heat pump is made to
start and stop via a serial RS-485 communications link
with a Pentair automation controller. This means the
remote automation controls override the heat pump’s
local set point.

However, the high and low temperature faults are still
active; the heat pump will not heat above 104° F. or cool
below 45° F.

To use the Serial Remote mode, 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.

The Address on the IntelliTouch® Address screen must
match the address being used on the heat pump. The
heat pump address can be changed from the Operator
Setup Menu as described below:

1. Press the UP and DOWN arrows simultaneously.
The Language Selection screen should be
displayed.

the AutoSet screen is displayed.

2. Press the UP or DOWN arrows to toggle between
the ON and OFF options.

Set the interval (1-4 hours) from the control panel to
control when the heat pump send a signal to check the
water temperature.

For example, if you program the heat pump control
board with a pump start time interval of 4 hours, have
the AutoSet feature enabled, and have a desired water
temperature of 80° F (27° C), this is the sequence of
events that will happen:

1. The heat pump displays a countdown window after
the filter pump shuts off.

PUMP START DELAY

REMAINING 4:00

2. After four (4) hours, heat pump will switch on and
start the filter pump depending on the temperature
set point.

3. 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, the heat pump will turn on and begin heating
the pool. If the pool temperature is above the set
point, the heat pump and filter pump will shut off.

4. At the time the water circulation pump shuts off,
the heat pump will reset and begin the countdown
interval and display ‘Pump Start Delay’ again.

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

6. Oncethe time clock turnson in the morning,the

heat pump will stop the AutoSet feature and resume
normal operation.

Enable this feature any time the filter pump is off. 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
water temperature.

If the temperature is not at the desired level, the heat
pump starts, along with the filter pump, until the water
reaches the desired temperature. The filter pump and
the heat pump will stop when the water reaches the
desired temperature.

AutoSet allows you to set intervals (1-4 hours) to control
when the heat pump senses the water temperature. Use
AutoSet to maintain the desired pool water temperature.

To use this feature:

Be sure the water circulation 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.

AutoSet Contactor to Mechanical Timer Wiring Example

Notes:

1. Mechanical timer is not provided with the heat pump.

2. Example only, other timers will be similarly wired.

3. Be sure that the electrical power lines are not crossed when
making connections.

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.

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:

Winterizing

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.

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.

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.

Continue onto the next page for “Owner Inspection”.

Owner Inspection, Continued

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.

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.

Troubleshooting

RISK OF ELECTRICAL SHOCK OR ELECTROCUTION.

Improper 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.

Always turn power to the unit OFF before servicing or repair.

Note: Any service must be done by an authorized service agency person.
