Safety messages / important information
This appliance is heavy, use two people or a mechanical lifting device.
Improper lifting may result in serious injury.
For safety and warranty, appliances that are damaged MUST NOT be installed or operated under
any circumstances.
Electrical warnings
DO NOT modify the electrical wiring of this appliance. If the control power wiring is damaged
or deteriorated then it must be replaced by an authorised person. Failure to do so may result in
electric shock, re, serious injury, or product failure.
All electrical connections MUST be made according to the wiring diagrams located on the panels of
the indoor and outdoor units.
The PCB is designed with a fuse to provide overcurrent protection. The specications of the fuse are
printed on the PCB. For units using R32 refrigerant, only a blast-proof ceramic fuse can be used.
Power voltage should be within 90-110% of rated voltage. Insu󰀩cient power supply can cause a
malfunction, electrical shock, or re.
Only connect the unit to an individual branch circuit outlet. DO NOT connect another appliance to
that outlet.
Electrical wires
This is a Class 1 electrical appliance. Make sure the live wire, neutral wire, and earth wire in the
power socket are properly connected. Inadequate or incorrect electrical connections may cause
re or electric shock.
The yellow-green wire in the air conditioner is the earthing wire which cannot be used for any other
purpose. Improper earthing may cause electric shock. The unit must be earthed in accordance with
local regulations.
Every wire must be rmly connected. Loose wiring can cause the terminal to overheat, resulting in
a product malfunction and possible re.
Do not let live wires touch or rest against refrigerant tubing, the compressor, or any moving parts
within the unit.
Circuit breaker
The circuit break must have the functions of magnetic tripping and heat tripping to prevent short
circuiting and/or overload. Use a standard circuit breaker and fuse conforming with the rating of the
appliance.
Fixed wiring
If connecting power to xed wiring1:
• A surge protector and mains power switch should be installed.
• A switch or circuit breaker that disconnects all poles and has a contact separation of at least
⅛ ″(3 mm) must be incorporated in the xed wiring.
HEAVY
Use two people or
a mechanical lifting device
1 Consult a qualied electrician as it must comply with AS/NZS 5601 and AS/NZS 3000 and other relevant local
regulations.

R32 refrigerant
This system uses R32 (diuoromethane) refrigerant, which is a ammable gas, class 2.2 according
to AS/NZS 1677 and must be handled by a qualied person with the appropriate refrigerant
handling license.
Make sure to check for and rectify any refrigerant leaks after you install or repair the unit.
Certain levels of refrigerant require minimum room sizes, refer table below. Please ensure that
these room sizes are adhered to for standard installations (up to 10 m pipe length). If larger
refrigerant charges than standard are used then please consult AS/NZS 60335.2.40 to determine
the safe minimum oor area for the installation.
Ensure the workspace is well-ventilated and completely free from any potential ignition sources
before working on the refrigerant system.
Never mix refrigerant types.

1 Sound pressure
Is what the listener (our ears hear). It is the pressure disturbance in the atmosphere, measured using
predened conditions, such as the location of the equipment, environmental conditions, and the distance from
which the sound is measured. Sound pressure level focuses on how loud the noise is at a specic location,
which can vary based on distance and surroundings.
1 Sound power
Measure of acoustic energy at the source. It quanties the overall noise produced. Sound power level is a
measure of how much noise the heat pump generates in total, irrespective of the distance from the source to
the listener.
