all of the warnings and cautions.

WARNING —

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.

4. Physical inability to exit the spa.

5. Fetal damage in pregnant women.

IMPORTANT SAFETY PRECAUTIONS (continued)

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.

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.

1

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

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

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

WITHIN A

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.

NOTE: For normal installations, do not install a shut-off valve or any kind of variable restriction in
the water piping between the heat pump outlet and the pool/spa.

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 [phone] 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.

Water Connections at the Heat Pump

Two inch Quick Connect fittings have been installed on the water inlet
and outlet connections, see

Figure 7. Filtered cool water is plumbed

to the inlet, located on the right side of the heat pump. Heated water
flows through the outlet, located on the left side of the heat pump.

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

CAUTION —

Make sure that flow requirements and pool water
turnover rates can be maintained with the installation of
additional heat pumps and plumbing restrictions.

Automatic Flow Control Valve

Outlet Union

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 100 gpm
(380 lpm). If the filter system flow rate is higher than 100 gpm (380 lpm), install a manual bypass valve, see

Figure 6 on page 7.

NOTE: Be advised that if your circulation pump is over 2 HP or if the total flow exceeds 100 gpm
(380 lpm), you will have to add an external bypass valve. Excess water flow will damage the heat
exchanger.

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.
