IMPORTANT WARNING AND SAFETY INSTRUCTIONS
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 — The U.S. Consumer Product Safety Commission warns that elevated water temperature can be
hazardous. See below for water temperature guidelines before setting temperature.
WARNING — The following “Safety Rules for Hot Tubs” recommended by the U.S. Consumer Product Safety
Commission should be observed when using the spa.
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 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.

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

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. [610 mm] access must be available in the front and 12 in. [30.5 mm] 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 five (5) feet [1520 mm] 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.

UltraTemp®Heat Pump Installation and User’s Guide
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
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
needwater,use atrickle typeirrigation sprinklerinstead ofthe broadcasttype.
The heater is designed to handle the wettest weather conditions that are
typical of 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 ishigh in minerals, sulphur andother 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
anchorboltsandtheappropriatesizeconcreteanchortomount
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.

Plumbing layout
Figure 6 illustrates the standard plumbing layout with a single heat pump unit. Follow the diagram from
right to left, the plumbing sequence is as follows:
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. Be sure to provide an optional manual
bypass valve between the pool and the heat pump outlet to protect from back-siphoning.
Arrangement of pool system components (other than Figure 6 and following diagrams) can affect the
operation of the heat pump’s water pressure switch. Location of the heat pump above or below the pool
water surface can also affect operation of the switch.
In general, the pressure switch can be adjusted to accommodate this effect if the heat pump water
connections are no more than 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
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
CAUTION — Make sure that flow requirements and pool water turnover rates can be maintained with the installation
of additional heat pumps and plumbing restrictions.
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.
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 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.

Multiple Unit Installation
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 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 Figure 8. 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.

Multiple Heat Pump Connections
All plumbing on multiple heat pump installations must be done in parallel see Figures 9 and 10. 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. See page 16 for details on when and how to adjust the pressure switch.
Each heat pump allows a maximum flow rate of 100 gpm (380 lpm) and requires a minimum of
30 gpm (110 lpm).
