3. GENERAL INFORMATION
3.1 The ability of the air-conditioner to maintain a desired temperature depends upon
the heat entering or leaving your vehicle. The following simple guidelines should be
followed to achieve the best comfort, lowest energy use and quietest operating noise.
a. Park your vehicle in a shaded area
b. Keep all windows, doors, curtain and blinds closed while operating
c. Select higher fan speeds for higher cooling performance
d. Switch your air-conditioner to cooling early in the day before the vehicle
interior has become too hot.
e. If the vehicle interior is already hotter than the outside air, briey open
doors and windows to exhaust the hot air before starting the air-
conditioner cooling.
f. Avoid using stoves and ovens that add heat to the vehicle interior while
the air-conditioner is cooling.
3.2 In humid conditions, the operation of an air-conditioner can cause the formation
of condensate on cold surfaces inside your vehicle. Care must be taken to prevent
this condensate damaging personal items, or causing a build up of mould. Items
that may be damaged by condensate must be kept clear of the air duct. In rare
circumstances, condensate can form on this duct during use. Should condensate
form, allow to dry thoroughly after use.
NOTE: Condensation can be reduced by keeping all doors and windows closed during air-conditioner operation,
preventing humid air from entering the vehicle. The likelihood of condensation on the duct can be reduced by
closing the doors of any cupboards that the duct passes through.
WARNING
If the supply cord is damaged, it must be replaced by the manufacturer, its service
agent or similarly qualied persons in order to avoid a hazard.
All electrical work, if necessary, should only be performed by qualied electrical
personnel. Repair to electrical components by non-certied technicians may result in
personal injury and/or damage to the unit. All electrical components replaced must
be genuine replacement parts, purchased form an authorised reseller.

a. The unit fuse and supply cord should only be replaced by a licensed
electrician. The fuse is located in the electrical control housing on the side
of the unit. Fuse rating is: 250V/500VAC, 10A, T-Delay, 5x20mm.
b. The air-conditioner must be disconnected from the power supply before
any disassembly or repairs.
c. The air-conditioner uses the refrigerant R407C under high pressure. It
is both dangerous and illegal to tamper with the sealed refrigerant system
without appropriate licensing. Deliberate release of refrigerant is illegal
in Australia.
3.3 The air intake, exhaust and condensate drain under the oor of the vehicle
must be kept clear of any material that may block airow. Failure to keep these
areas clear could cause poor performance, water leakage into your vehicle and
permanent damage to the air-conditioner.
3.4 The interior air intake on the side of the air-conditioner must always be kept clear.
A minimum 40mm gap is required from any xed wall, and personal belongings
must not be placed near the inlet.
3.5 The air-conditioner must never be operated while the vehicle is moving. The
vehicle should be parked with the unit tilted no more than 8° from horizontal.
3.6 This unit is designed to be operated on 230-240V 50Hz power from the electricity
grid or a sine wave inverter equipped generator. The recommended generator
capacity for this unit is 2.8kVA.

5. OPERATION
Connect the air-conditioner power supply cord to a 10A power outlet.
CAUTION
Always ensure that the power supply cord is fully uncoiled before operating the
unit to prevent overheating. The power cord must be routed so that it cannot be
damaged during use or when in transit.
The Power Indicator (I) will illuminate briey when the power supply is connected and
switched on.
5.1 Switch the air-conditioner on by pressing the Power button (A) on the remote
control while aiming the control in the direction of the air distribution unit
Infrared Remote Control Receiver (J). The air-conditioner will beep and the Power
Indicator (I) will illuminate to acknowledge the signal.
5.2 Set the desired operating mode (Fan, Cooling or Heating), Fan Speed (Low, Med
or High) and the desired temperature (16-30°C). The interior fan, exterior fan and
compressor will operate automatically depending upon the settings chosen. Fan
speed should be selected manually to the lowest level that achieves the desired
room temperature.
Once the desired room temperature is reached, the air-conditioner will cycle the
compressor and exterior fan to maintain the temperature level.
If the air-conditioner cannot reach a comfortable temperature in cooling mode, increase the
fan speed to increase performance.
The desired temperature can be adjusted if you are too hot or cold.

The compressor and exterior fan speed are microprocessor controlled to automatically
ensure a long life for your air-conditioner while maintaining the best possible comfort.
Depending upon the conditions and air-conditioner settings, you may notice some of
the following:
a. Automatic Compressor Start Protection: The compressor start may be delayed for
up to 3 minutes after selecting cooling or heating mode.
b. Exterior Fan Speed: The exterior fan may switch between high and low speeds to
minimize the operating noise of the air-conditioner for you and your neighbours.
c. Cooling Operating Range: The compressor may not operate in cooling mode if
both the indoor and outdoor temperatures exceed approximately 40°C in order
to protect the refrigerant system. On very hot days start the air conditioner early
to maintain a low indoor temperature. Always keep doors, windows and curtains
closed and park in a shaded position to reduce the heat load.
d. Heating Operating Range: The air-conditioner is designed to operate in heating
mode when the outside temperature is between 0-25°C. If the temperature
is outside this range the compressor may not operate in order to protect the
refrigerant system.
e. Preheat: The interior fan will not switch on in heating mode until the air-
conditioner has warmed up suciently to deliver comfortably warm air. At
very low temperatures this could take up to 10 minutes from the start of the
compressor and exterior fan.
f. De-icing: The air-conditioner operates as a heat pump when in heating mode.
Heat is drawn from the outside air to warm the vehicle. As the outside air
temperature drops, less heat is available to the air-conditioner and a decrease
in the heating performance may be noticed. When the outside temperature
is very low (0-8°C) ice may form on the condenser in the air-conditioner. The
microprocessor control has a fully automatic protection function that will remove
the ice when required. Depending upon the conditions you may notice the
compressor, interior and exterior fans switching o as often as every 15 minutes
to protect your air-conditioner and provide maximum comfort.
