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.

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.

Specification may change without notice.
