BEFORE INSTALLING THE HEAT PUMP
General Installation Information
Your Pentair heat pump will provide you with years of
heatedpoolenjoyment.Heatpumpsoperatebytaking
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,theheat pumpshouldraise your poolonaverage
1° F per hour depending on air temperature, humidity,
andwatertemperature.Theidealorratedconditionfor
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
pumpwillturnonandoffautomaticallytomaintainyour
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.
Yourheatpumpwillstill operate whenthetemperature
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
Correct installation is required to assure safe operation.
The requirements for Pentair heat pumps include the
following:
• Dimensions for critical connections.
• Field assembly (if required).

INSTALLATION AND LOCATION
Only a qualified service person should install the
UltraTemp® 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
Forproperdrainageofcondensationandrainwater,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 forrunoff.
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.

Anchor clamps hold the heat pump to the equipment
pad in order to withstand high winds caused during
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 to the
right.
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 appro-
priate size concrete anchor to mount the clamp to
the equipment pad. Be sure to check local codes.

HeatPump InstallationandUser’s Guide
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 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,
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 of30
gpm (110 lpm) after the directional fittinginstallation.
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
temperaturetocallforheat.TurntheheatPumpON.
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. Removetheheatpump’sleftfrontpanelandremove
remainingrightfrontpanel.Thewaterpressureswitch
is located in the water plumbing in the lower right
corner of the heat pump.
6. Slowly rotate the adjustment wheel on the water
pressureswitchinaclockwisedirectionuntilthe“LOW
WATER FLOW” Alarm shows on the LCD, the red
SERVICE light turns ON, and the heat pumpstops.
7. Check the setting of the water pressure switch by
starting and stopping the filter pump and checking
thecontrolpanelandoperationoftheheaterbetween
each flow change.
8. If the water pressure switch cannot be adjusted to
accommodatetheconditionslistedabove,anexternal
flow switch must be added to the plumbing system
toensurethat theheatpumpwillnot 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 thewater
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 countdownwill
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 clockwisedirection
until the “LOW WATER FLOW” Alarm showson
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.
9. If the water pressure switch cannot beadjusted
to accommodate the conditions listed above,
an external flow switch must be added tothe

Multiple Unit Installation
1. Heat Pump, Heater and/or SolarCombination
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
anycombinationof heat sources includingsolar.All heat
sources must be plumbed in series to work correctlyand
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 applybyeliminating the component in the illustration
that is not a part of your system.
HEATER
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).

Electrical Connections and Wiring
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 10-11.
The UltraTemp® 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.
For Canada, a 6 AWG or larger solid copper bonding
conductor is required.. 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.
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.
The following is the procedure to wire the heat pump
to the electrical source:
Be sure the power to the circuit for the heat pump
is turned off.
1. Remove the front left panel of the heat pump
cabinet, (you do not need to remove thestar-head
screw at the top left corner).
2. Remove the service panel to the heat pump
electrical compartment. (Front left corner ofunit)
3. Electrical supply lines must be run through
watertight conduit. Run the wires and conduitfrom
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 diagram.
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) (6 AWG
in Canada) to the bonding lug on the left side of
the heat pump.
