TRANSPORT DAMAGE
As soon as the unit is delivered to site, check
for evidence of freight damage. If there is any
damage, file a claim with the transport
company immediately, and contact your
Carrier representative.
LOCATION OF UNIT
•Consult local building codes for any
special building requirements and noise
level limitations.
•Leave sufficient clearance around the unit
for service access and for proper air flow
through the unit.
•Avoid complaints from neighbours by
locating the unit away from neighbouring
structures such as windows or hard
surfaces that might reflect and amplify
noise.
WEATHER PROOF
Carrier Heat Pumps are completely weather
proof and are suitable for mounting indoors
(e.g. garages, etc) or outdoors.
MOUNTING
The unit should be mounted on a level base,
ideally a concrete slab, or equivalent
structure.
INDOOR INSTALLATION
When mounted indoors, the Heat Pump outlet
should exhaust to outside and have a 600mm
minimum clearance on the side indicated
below, for service access. The Heat Pump
needs to draw air from inside the room, so
ensure there is some means for the air to
seep in. (wall grille, door grille, etc..)

OUTDOOR INSTALLATION
The unit should be located away from
sources of dust, leaves, debris or other loose
material that may drift into and obstruct the
air intake.
SITING
The unit and its associated isolating switch
must be installed no closer than 3.0m from
the end of the pool.
SUN HEAT
Unlike solar panels, Heat Pumps are not
dependent on sunlight for proper operation.
The Heat Pump will operate efficiently
whether in sunlight or shade.
VENTILATION
Enough room should be allowed around the
unit for proper air flow to the air intake. Cold
'exhaust' air should not be allowed to short
circuit back into the air intake.
PIPING
The Heat Pump has standard 40mm PVC
pipe connections. Pipe to the Heat Pump
upstream of the filter assembly to ensure only
filtered water goes through the heat
exchangers. Where a salt water chlorinator is
installed, re-pipe the chlorinator after the Heat
Pump. Use mack unions for connection to
the Heat Pump.
WIRING (see back page for connection diagrams)
The electrical connection to the Heat Pump
must comply with the local supply authority's
requirements and wiring regulations. Typical
requirements are as follows;
•A weather proof (IPX4) motor-rated
switch must be installed adjacent to the
Heat Pump and no closer than 3.0m from
the edge of the pool.
•The electrical wiring protection must be
rated for the motor starting current.
•Electrical and controls cabling to the Heat
Pump should be routed through the
internal conduit provided to avoid wire
contact with hot pipes connected to the
compressor.
TECHNICAL SPECIFICATIONS
START UP PROCEDURE
1. Read the Installation and Operating
Instructions carefully.
2. Ensure the location and siting of the Heat
Pump allows unrestricted air flow to and
from the unit.
3. Avoid short circuiting air flow from the air
discharge (exhaust) back into the air
intake.
4. Ensure the Heat Pump is level.
5. Ensure all circuit breakers, fuses, cabling
and circuits are of the correct sizes and
type for the application.
6. Pre-set the thermostat to 28oC (for pools
& 38oC for spas).
7. Switch on the main isolator to the Heat
Pump, and turn on control switch. (RED
light glows)
8. Start the circulating pump.
9. The Heat Pump will automatically start up
when the water pressure reaches its
setpoint. The AMBER light will glow and
the thermostat will indicate the current
water temperature.
10. Ensure that the water pressure switch
shuts off the Heat Pump when the
circulating pump stops.

SETTING UP THE HEAT PUMP
1. WATER PRESSURE SWITCH
The water pressure switch senses when the
circulating pump is running and ensures there
is water flow before the Heat Pump starts. It
is factory set to start the Heat Pump when the
water pressure reaches 35 kPa and stops it
when it falls below 20 kPa. The water
pressure switch (which is located close to
where the refrigerant pipes enter the heat
exchanger), is adjustable.
If the pressure is too low to activate the water
pressure switch (AMBER light glows),
proceed as follows :-
1. Check filter condition and clean or
backwash if required.
2. Check for blocked lint pot or skimmer box.
3. Disconnect any pool accessories, such as
pool vacuums, that may be hindering
flow.
4. With the Heat Pump switched off, lower
the pressure switch setting and listen for
a distinct 'click' as the circulating pump
starts and stops.
5. If the Heat Pump is located lower than the
water level of the pool, the 'head' of pool
water may be sufficient to hold the water
pressure switch in the ON position.
Adjust the water pressure switch setting
to avoid this happening.
6. If the water flow into the pool is
unrestricted (open pipe or without jets), a
restrictor or tamper-proof valve needs to
be installed to increase the water
pressure to around 50 kPa.
2. WATER TEMPERATURE CONTROL
The controller displays the temperature of the
water entering the Heat Pump. Adjust the
thermostat to approximately 28oC. Press
'SEL' to display the current setpoint then
adjust with the up and down arrows. Press
'SEL' again to set the desired temperature.
3. SIGNAL LAMPS
Both the red and amber lights must be on
before the Heat Pump will start. Each light
indicates the following :-
•RED - glows when the Heat Pumps'
control switch has been turned on and
there is power to the unit.
•AMBER - glows when the circulating
pump is running and the water pressure
switch has closed. (I.e. there is sufficient
water flowing).
REFRIGERANT PRESSURE SWITCHES
The Heat Pump has other safety devices
which may prevent the unit from operating
while a non-critical fault exists. These are the
refrigerant high pressure and low pressure
cut-out switches.
If both the red and amber lights are on, and
the Heat Pump fails to start, switch off the
control switch and the power supply, then
turn both back on. This should re-set both
high and low pressure switches. The Heat
Pump should start again.
If after a brief period of 2 to 15 minutes, it
stops again, check that there is sufficient
water flow and that there are no blockages in
the pipes.
If the water flow is high, check the unit again
after 10 minutes.
If the unit stops again, turn off the power and
call your Carrier representative or the
company you purchased the Heat Pump
from.
WARNING!
SALT CHLORINATORS
Excessive chlorine in the pool water,
compounded by variable heating and filtration
cycles, may increase corrosion in the heat
exchanger material. Monitor the chlorine
levels in the pool regularly (daily is
recommended) to keep it within safe limits.
Also, maintain the pool within the water
temperatures recommended in the Owner's
Manual.

ELECTRICAL CONNECTIONS
CONTROLLER
DISPLAY
The controller displays the temperature of the
water entering the heat pump, which is also
the temperature of the pool.
SET POINT
The set point temperature is the pool
temperature that the heat pump will aim for
and maintain. To view the current set point
temperature, press the 'SEL' key.
To change the current set point temperature,
press 'SEL' then use the and the keys to
change the temperature setting. To complete
setting the temperature, press 'SEL' again.
NOTE
1. For servicing, use R22 refrigerant only.
2. The thermostat has a 10 second delay
from time of switching.
3. The compressor has a 1 to 5 minute time
delay. The fan starts before the
compressor.
