WARNING
• When wiring the power supply and connecting the wiring between the indoor and outdoor units, position the wires
so that the control box lid can be securely fastened.
Improper positioning of the control box lid may result in electric shocks, fi re or overheating terminals.
• After connecting interconnecting and supply wiring, be sure to shape the cables so that they do not put undue force
on the electrical covers or panels. Install covers over the wires.
Incomplete cover installation may cause terminal overheating, electrical shocks, or fi re.
• When installing or relocating the air conditioner, be sure to bleed the refrigerant circuit to ensure it is free of air, and
use only the speci fi ed refrigerant (R32).
The presence of air or other foreign matter in the refrigerant circuit cause abnormal pressure rise, which may result in equipment damage
and even injury.
• The installation height from the fl oor must be over 2.7m.
• If refrigerant gas leaks during installation, ventilate the area immediately.
Toxic gas may be produced if the refrigerant comes into contact with fi re.
• After completing installation, check for refrigerant gas leakage.
Toxic gas may be produced if the refrigerant gas leaks into the room and comes into contact with a source of fi re, such as a
fan heater, stove or cooker.
• During pump-down, stop the compressor before removing the refrigerant piping.
If the compressor is still running and the stop valve is open during pump-down, air will be sucked in when the refrigerant piping is removed,
causing abnormal pressure in the refrigeration cycle, which may result in equipment damage and even injury.
• During installation, attach the refrigerant piping securely before running the compressor.
If the refrigerant pipes are not attached and the stop valve is open when the compressor is run, air will be sucked in, causing abnormal
pressure in the refrigeration cycle, which may result in equipment damage and even injury.
• Be sure to earth the air conditioner.
Do not earth the unit to a utility pipe, lightning conductor or telephone earth lead. Imperfect earthing may result in electric shocks.
• Be sure to install an earth leakage breaker. Failure to install an earth leakage breaker may result in electrical shocks,
or fi re.
• All electrical wiring must not touch the water piping or any moving parts of the fan motors.
• Con fi rm that the unit has been switched OFF before installing or servicing the unit.
• Disconnect from the main power supply before servicing the air conditioner unit.
• DO NOT pull out the power cord when the power is ON.
This may cause serious electrical shocks which may result in fi re hazards.
• Keep the indoor and outdoor units, power cable and transmission wiring, at least 1m from TVs and radios, to prevent
distorted pictures and static.
Depending on the type and source of the electrical waves, static may be heard even when more than 1m away.
• Do not use means to accelerate the defrosting process (if applicable) or to clean, other than those recommended by
the manufacturer.
• The appliance must be stored in a room without continuously operating ignition sources (for example: open fl ames, an
operating gas appliance or an operating electric heater).
• Do not pierce or burn.
• Be aware that refrigerants may not contain an odour.
• The appliance must be installed, operated and stored in a room with a fl oor area larger than Xm2 (refer to Section
“Special Precautions When Dealing With R32 Unit”).
In case it does not satisfy minimum fl oor area, it requires to install at good ventilation room.
• NOTE: The manufacturer may provide other suitable examples or may provide additional information about the
refrigerant odour.
