. General Information
CONGRATULATIONS on your purchase of an ActronAir air conditioning unit! This unit has been designed and engineered
to provide optimum air conditioning and to achieve maximum energy efficiency.
Your air conditioning system has been manufactured from the highest quality materials. Numerous “in house” and
“external” inspections and test procedures were conducted to your air conditioning unit to ensure satisfactory operation.
This guide provides operation instructions specific to your split indoor unit. Read this manual thoroughly to ensure safe
operation of your air conditioning system.
. Safety Instructions
•Only licensed HVAC technicians* should service this air conditioning equipment. Improper service or alteration by
an unqualified technician could result in significant and major damage to the product or property which may render
your warranty null and void. Such unqualified service could also lead to severe physical injury or death. Follow all safety
instructions in this literature and all warning labels that are attached to the equipment.
•Prevailing WH&S regulations must be observed and will take precedence to the safety instructions contained on this
manual. Safe work practices and environment must be the paramount importance in the performance of all the service
procedures.
•This appliance is not intended for use by young children or infirm persons unless they have been adequately supervised
by a responsible person to ensure that they can use the appliance safely. Young children should be supervised to ensure
that they do not play with the appliance.
*Qualifications required will be appropriate Electrical, Refrigeration and Refrigerant Handling License and Training
dependent on local State/Territory regulations.
DANGER
Hazardous Voltage - Risk of Electrocution.
Turn Off the power from main isolator before proceeding with any service and maintenance work of the unit. Observe proper
LOCK-OUT/TAG-OUT (LOTO) procedures for electrical appliances in order to prevent accidental switching-on of the power
supply. Extreme care and caution must be observed should there be a need to work on live circuit.
WARNING
• If any abnormal situation arises (like burning smell), turn of the power supply and call your HVAC technician for instructions
to avoid electric shock, fire or injury.
• DO NOT let the indoor unit or the controller get wet. It may cause electric shock or fire.
• DO NOT insert fingers, rods or other objects into the air inlet or outlet. This may cause injury, since the fan may be rotating
at high speeds.
• DO NOT use a flammable spray such as hair spray, lacquer or paint near the unit. This may cause fire or combustion.

CAUTION
• DO NOT inspect the unit by yourself. Ask a qualified HVAC technician to perform the inspection.
• To prevent product deterioration, do not use the air conditioner for preservation purposes (storage of food, plants, animals,
works of art, etc.).
• DO NOT operate the air conditioner with wet hands. It may cause electric shock.
• DO NOT touch the evaporator coils inside the indoor unit. The evaporator coils are sharp and may cause injury.
• DO NOT place items that might be affected by moisture damage under the indoor unit. Condensation can occur at a relative
humidity of 80%.
• DO NOT expose heat-producing appliances to cold air or place them under the indoor unit. This may cause incomplete
combustion or deformation of the unit due to the heat.
• If the air conditioner is used together with other heating devices, thoroughly ventilate the room to avoid oxygen deficiency.
• DO NOT climb onto or place objects on top of the outdoor unit.
• DO NOT operate the air conditioner when using fumigant insecticides. The chemicals may become layered with the unit and
endanger those who are hypersensitive to chemicals.
• DO NOT let children play with the air conditioner.
• DO NOT operate the air conditioner in a wet room (e.g. bathroom or laundry room). This can cause electrical shock and cause the
product to deteriorate.
WARNING
This air-conditioning unit contains R-32 refrigerant (CLASS A2L) which is mildly flammable. Refer to R-32 Safety Manual, provided
with the unit.
NOTE
• Service, maintenance, repairs and decommissioning of this unit must be performed by a licensed HVAC technician; qualified
to handle R-32 refrigerant.
• R-32 refrigerant is odourless, if the refrigerant gas comes into contact with fire, it may emit a poisonous gas.
• Do not continuously operate open flames and ignition sources in the room.

03.02. Achieving Optimal Performance
Optimal performance for the COOL, HEAT, and DRY mode can be achieved in the temperature ranges shown
in the table below. If the unit is used outside of these ranges, certain safety protection features will activate and
cause the unit to perform at a reduced capacity.
COOL Mode HEAT Mode DRY Mode
Indoor Temperature 17°C - 32°C 0°C - 30°C 10°C - 32°C
Outdoor Temperature -15°C - 60°C 25°C - 30°C 0°C - 60°C
NOTE
To further optimize the performance of the unit, do the following:
• Keep doors and windows closed.
• Limit energy usage by using TIMER ON and TIMER OFF functions.
• Do not block air inlets or outlets.
• Regularly inspect and clean air filters.
03.03. Features
NOTE
Refer to remote manual for full features list.
Auto-Restart
If the unit loses power, it will automatically restart with the prior settings once power has been restored.
Anti-mildew
When the unit is turned off after COOL, AUTO or DRY mode, the unit will continue to operate a low power to dry up
condensed water to prevent mildew growth.
Easyconnect Control (Optional)
Allows you to control the unit using a mobile phone and a wireless connection. Installation is required to be undertaken
by a licensed technician. Easyconnect is an accessory that may be purchased separately.
Louvre Angel Memory
When turning on your unit, the louvre will automatically resume its former angle. Aim the louvre higher to avoid direct
airflow. This setting is found under the SET menu.
Active Clean Function
It washes away dust, mold and grease when it adheres to the heat exchanger, by automatically freezing and then rapidly
thawing frost. Active Clean function is used to produce more condensed water to improve the cleaning effect. After
cleaning, the internal blower fan operates with hot air to blow-dry the evaporator and prevent the growth of mold.
When this function is turned on, the indoor unit will display CL. After 20 to 45 minutes, the unit will turn off
automatically and Active Clean function will be deactivated.

Breeze Away
This feature stops direct air from blowing onto you.
Refrigerant Leakage Detection
The indoor unit will automatically display EL0C when it detects refrigerant leakage. Switch system off and contact
service or installer.
Intuitive Proximity Sensor
This feature detects the occupancy of the people in the room. When in COOL mode, if you are away for 30 minutes, the
unit will automatically lower the frequency of the unit to save energy. The unit will automatically resume operation after
sensing activity in the room.
LED Display
Press the LED button on the remote control to turn off the indoor unit panel display and cancel the 'beep' noise.
Freeze Protection
When the unit is on HEAT mode and indoor temperature drops below 8 °C - FP will be displayed and system will enter
freeze protection mode.
03.04. Setting Vertical Angle of Air Flow
While the unit is on, use the SWING button on the remote control to set the vertical angle airflow direction. Refer to
Remote Control manual for more details.
03.05. Setting Horizontal Angle of Air Flow
While the unit is on, press and hold the SWING button on the remote control to set the vertical angle airflow direction.
Refer to Remote Control manual for more details.
NOTE
• When using COOL or DRY mode, do not set vertical louvre to the minimum angle for long periods of time. This can
cause water to condense on the louvre blade, which may drop on your floor or furnishings.
• When using COOL or HEAT mode, setting the vertical louvre to the minimum angle can reduce the performance of
the unit due to restricted air flow.
• Do not move louvre by hand. This will cause the louvre to become out of sync. If this occurs, reset mains power supply
isolator to restart the unit. This will reset the louvre.
CAUTION
Do not put your fingers in or near the blower. The high-speed fan inside the unit may cause injury.
