- All applicable local codes and ordinances.
- Always disconnect power at the circuit breaker before servicing the load centre.
Failure to do so could result in death or serious injury to installer, service person, pool
users, or others due to electrical shock.
- Improper installation can create an electrical shock hazard that can result in death or
serious injury.
WARNING
Water temperature in excess of 38 degrees Celsius may be hazardous to your health.
Prolonged immersion in hot water may induce hyperthermia. Hyperthermia occurs
when the internal temperature of the body reaches a level several degrees above
normal body temperature of 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) Foetal damage in pregnant women. 6) Unconsciousness resulting in
danger of drowning.

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 (50mm).
2. Level surface for proper drainage.

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 isolation switch that will interrupt all power to the unit. This switch must be within line of
sight of the heat pump. Check local codes and wiring rules (see page 4) for requirements.
5. Watertight conduit to run the electrical supply line.

Note: Be sure that the pad is pitched not more than 20mm per metre 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 (up
to 20L 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 con-
nected 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.

height of walls, and proximity to public access areas. The UltraTemp® Heat Pump must be placed to
provide clearances on all sides for maintenance and inspection.
1. At least 1.5m access must be available in the front and 250 mm on all the other sides of the heat

2. If the heat pump is to be installed under a cover or under a vertical overhang, the unit must have
a minimum of 1.5m clearance from the top of the heat pump. (Manufacturer’s recommendation).
3. Install a minimum of 1.5m from the inside wall of the pool or spa unless the heat pump is separated
from the pool or spa by a 1.5m high solid fence or other permanent barrier.
4. Install heat pump a minimum of 250mm from the wall of the house.
5. Allow 600mm clearance above the heat pump for service access.

Anchor Clamp Installation
Installation of the anchor clamps is recommended in all installations. Anchor clamps hold the heat
pump to the equipment pad in order to withstand high winds, accidental movement and excessive
vibration.
To install the anchor clamps:
1. Be sure the heat pump is in its permanent location on the equipment pad.
2. Locate 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 (M6x 35
mm) 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 anti-vibration pad (included) under each anchor clamp.
Installation

Page 12
4. Mark the position of the hole in each clamp on the equipment pad.
5. Use a masonry drill bit and drill a hole in the cement with a diameter as determined by the concrete an-
chor, at each of the marks on the equipment pad. The hole should be approximately 4 cm deep.
6. Insert a bolt anchor into each of the holes. Be sure the anchors are set completely into the holes.
7. Position the anchor clamps so that the holes in the clamps are over the bolt anchors. Be sure that
the clamp hooks are over the lip of the heat pump base.
8. Insert an anchor bolt through each clamp into the anchor and tighten to secure the clamp and heat
pump to the equipment pad.

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, dur-
ing 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

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 panel of the heat pump cabinet (you need to loosen the front screws on the top
panel aswell).
2. Remove the service panel to the heat pump electrical compartment.
3. Electrical supply lines must be run through watertight conduit on the front panel. Run the wires
and conduit from the power source and connect them to the conduit connection. Use suitable gauge
connection wire as per below table.
4. Connect the power leads to the terminals in the electrical compartment as shown in the wiring
diagram.
5. Verify that all other wires are secure, they may have loosened during shipment.
6. Connect the ground wire to the ground lug provided.
7. Replace the service panel and reinstall screws to hold it in place.
8. Replace the front panel.

Code Parameter Name Description Range Default
L2 Temperature
Differential
Set how much the water temperature needs to
drop below the set temperature, for the heat pump
to start up again. E.g. If the set temperature is 280C
and the water temperature is 280C, the heat pump
will stop heating and not restart until the water
temperature drops to 260C (if the Temperature Dif-
ferential is set to 20C).
1~250

1~50
20C
L3 Heat Mode Temp This is the set temperature when in Heat mode. 5~400C280C
L4 Cool Mode Temp This is the set temperature when in Cool mode. 5~320C120C
L5 Compressor
Current
Set upper limit of compressor current. There will be
an alert if value exceeds this limit. ‘0’ for no detec-
tion.

L6 Buzzer This parameter sets an audible buzzer on or off
when the heat pump goes to an error mode.

L7 Sampling Mode The UltraTemp heat pump can run a dedicated
circulation pump, which can operate in either
always on (inside of scheduled times) or in a sam-
pling mode. Sampling mode will turn the circulation
pump on every 30 minutes to sample the water
temperature. If the water temperature is below
the set temperature (or above in cooling mode) the
heat pump will turn on and the circulation pump
will continue to run until the set temperature is
reached. If the water temperature is above the set
temperature (or below in cooling mode), the circu-
lation pump will turn off again for another 30 min-
utes.
