IMPORTANT SAFETY INSTRUCTIONS
•Never remove any fixed covers on the indoor or outdoor unit. Removal of the covers
may expose fast moving fan blades or electrical components operating at a hazardous
voltage. Contact with the blades or high voltage components may result in injury or
electric shock.
•Never insert any objects into the openings in the indoor or outdoor unit. This may
damage the product or result in injury to the person inserting the object.
•Do not expose the indoor unit or remote controller to rain or moisture. Water or other
fluids on the electrical components may result in fire or electric shock.
•Always replace any blown fuse with a fuse of the same specification. The use of the
wrong type fuse may allow the electrical wiring to overheat and catch on fire. If the
correct type fuse continues to blow contact your installer or electrician.
•Never operate the air conditioner without the return air filter(s) in place. Operating the
unit without the filter(s) will allow dust to enter the indoor unit and build up on the heat
exchanger coil and fan motor. This will cause a malfunction of the unit which will not be
covered by Warranty.
•This electrical appliance is not intended for use by young children. Young children
should be supervised to ensure that they do not play with the outdoor unit.
MAIN SWITCH
Ensure that your installer shows you the location of the main power switch for the air
conditioning system. This switch is normally located adjacent to the outdoor unit or in
the fuse box / switchboard.
The main switch must be turned on at least 6 hours before the air conditioner is
operated to warm up the compressor. Failure to do so may result in damage to the
compressor which will not be covered by warranty.
If the air conditioner is not going to be used for an extended period of time or you are
going away on holidays, the main switch should be turned off to prevent accidental
operation of the air conditioner. Remember that the main switch must be turned back
on at least 6 hours before operating the air conditioner.

AUTOMATIC HEATING / COOLING CHANGEOVER
(Heat Pump Models Only)
When the air conditioner is operated in this mode it will automatically switch between the
heating and cooling mode.
1. Press the MODE SELECTION BUTTON (24) (if required) until the AUTO MODE
INDICATOR (7) is displayed.
When the AUTO MODE is selected either the COOL or HEAT MODE INDICATOR
will also be displayed along with the most recent temperature setting. (ie. if the last
adjustment you made was the set the cooling mode temperature to 23° then when
you select the AUTO MODE it will display AUTO COOLING at a temperature of 23°).
The air conditioner will then measure the room temperature and select the applicable
mode (ie. heating or cooling) based on the current and desired room temperature.
2. Adjust the desired room temperature (if required) by momentarily pressing on the top
or bottom section of the TEMPERATURE SET BUTTON (21) until the desired
temperature is displayed. Each press of the button will increase or decrease the

PROGRAM TIMER
The air conditioner can be programmed to automatically turn on or off in 1 hour
increments up to 72 hours in advance. It may also be programmed to turn on for a
determined time then off again or vice versa provided that the last operation (ie. switch on
or off) is within 72 hours.
PROGRAMMING THE STOP TIME
1. Press the TIMER MODE SELECT BUTTON (17) once. The PROGRAM STOP TIME
INDICATOR (11) will flash.
2. Select the desired STOP TIME by momentarily pressing on the top or bottom section
of the PROGRAM TIME BUTTON (20) until the desired elapsed time is displayed.
Each press of the button will increase or decrease the elapsed time by 1 hour.
3. Once the desired STOP TIME is displayed press the PROGRAM TIMER ON/OFF
BUTTON (18). The PROGRAM STOP TIME INDICATOR (11) will stop flashing and
remain displayed.
4. Operate the air conditioner in the desired mode as described above. The PROGRAM
STOP TIME INDICATOR (11) will count down towards zero. When zero is reached
the air conditioner will stop operating.
PROGRAMMING THE START TIME
1. Press the TIMER MODE SELECT BUTTON (17) two times (or only once if a stop
time has been set). The PROGRAM START TIME INDICATOR (12) will flash.
2. Select the desired START TIME by momentarily pressing on the top or bottom
section of the PROGRAM TIME BUTTON (20) until the desired elapsed time is
displayed. Each press of the button will increase or decrease the elapsed time by 1
hour.

3. Once the desired START TIME is displayed press the PROGRAM TIMER ON/OFF
BUTTON (18). The PROGRAM START TIME INDICATOR (12) will stop flashing and
remain displayed.
4. Set the air conditioner in the desired mode as described above but do not press the
ON/OFF BUTTON (1). The PROGRAM START TIME INDICATOR (12) will count
down towards zero. When zero is reached the air conditioner will start operating.
PROGRAMMING THE START AND STOP TIME
It is possible to set both the start and stop time so that the air conditioner either starts after
a predetermined time and then stops after a further predetermined time or stops after a
predetermined time and then starts again after a further predetermined time.
This is achieved by setting both the on and off time as described above. For example if
you require the air conditioner to stop in 3 hours time and then start up again 6 hours later
you would program a stop time of 3 hours and a start time of 9 hours (ie. 3 + 6 hours).
CANCELLING THE START OR STOP TIME
If you change your mind and do not want the air conditioner to automatically start or stop
simply press the PROGRAM TIMER ON/OFF BUTTON (18) and the START or STOP
TIME INDICATOR will extinguish.
ADVANCED FEATURES
FILTER CLEAN INDICATOR
The indoor microprocessor monitors the accumulated running time of the unit and after a
preset number of running hours displays the FILTER CLEAN INDICATOR (15) on the
remote controller. This indicator is a reminder to check and clean (if required) the return
air filter(s).
After you have inspected and cleaned the filter(s) press the FILTER CLEAN RESET
BUTTON (22) to extinguish the display and reset the accumulated time counter.
As the type of filter is selected by your installer it is not possible for us to describe the
method of removing and cleaning the filter(s). Please consult your installer regarding the
maintenance of the air filter(s).
DEFROST FUNCTION
During heating at low outside air temperatures it is possible for frost to build up on the
outdoor unit heat exchanger. This build up of frost will restrict the airflow through the heat
exchanger and therefore the performance of the air conditioner will gradually be reduced.
As the outdoor unit microprocessor is constantly monitoring system performance and
ambient temperature it will recognise that frost is building up on the heat exchanger and
activate the defrost mode.
When the unit enters the defrost mode both the indoor and outdoor fans will stop and the
DEFROST INDICATOR (16) will be displayed on the remote control. The unit will remain
in the defrost mode for around 4 to 8 minutes (10 min. max.) during which time the heat
exchanger will warm up to defrost itself.

11
HOT START SYSTEM
(Heat Pump Models Only)
To prevent a cold blast of air when the air conditioner turns on in the heating mode the
indoor unit incorporates a computer controller hot start system.
The indoor unit microprocessor monitors the temperature of the indoor heat exchanger
and operates the indoor fan at a speed lower than the normal low until the heat exchanger
temperature reaches a target temperature. When this target is reached the fan switches
from extra low to normal low. The air conditioner will then operate at normal low until a
second higher target temperature is reached at which point the fan will switch to selected
speed. This hot start feature is also utilised after defrost and during the heating cycle
when the compressor switches back on after the room temperature has fallen more than
1°C below the selected temperature.
AUTOMATIC RESTART AFTER POWER FAILURE
If the air conditioner is operating during a power failure it will automatically restart in the
same mode when the power is restored.
DUAL REMOTE CONTROL OPERATION (Optional)
A second (optional) remote control may be added to the system to allow setting and
control of the unit at two different locations. This is particularly useful in two storey
applications where one controller can be installed upstairs and the other controller
downstairs. When dual controls are used the air conditioner will obey the last command
entered into either controller. Both controllers will display the same information so if the
temperature on the downstairs controller is increased from 21 to 23 degrees, the upstairs
controller will also indicate 23 degrees.
EFFECTIVE OPERATION
For best results from your air conditioner we recommend the following:-
•Do not leave open any windows or door which will allow the loss of conditioner air.
•Draw blinds or curtains over windows to prevent direct sunlight entering during the
cooling cycle.
•Set the desired room temperature to avoid excessive heating or cooling.
•Keep the air filters clean.

12
SELF DIAGNOSIS FUNCTION
In the unlikely event that a fault develops with the air conditioner the microprocessor in the
indoor and outdoor units will diagnose the fault (where possible), display a unique fault
code on the remote controller (see below) and flash the OPERATION INDICATOR (2) on
and off. If this occurs take a note of the fault code (eg. E9) and contact your installer. This
code will indicate to the installer / repairer what the problem may be.
MAINTENANCE
•Regularly clean the indoor return air filter(s).
•Regularly inspect the outdoor unit to ensure the heat exchanger coil (aluminium fins)
and fan outlet are not obstructed by vegetation or any other foreign objects.
•Clean the outdoor unit heat exchanger coil annually or as required by location or
outdoor air quality. The coil may be cleaned by spraying the fins with low pressure
water in a downwards direction (ie. simulating heavy rain). Alternatively have the work
done by your installer.
•Regularly check the paint work of the outdoor unit for scratches or signs of corrosion.
Apply touch up or anti-corrosion paint as necessary.
