The two-dimensional bar code
is a manufacturing code.
• Be sure to use only the specified accessories and parts for installation work. Failure to use the specified parts may result in the unit falling, water leakage, electric shocks or fire.
• Electrical work must be performed in accordance with relevant local and national regulations and with the instructions in this installation manual.
Be sure to use a dedicated power supply circuit only. Insufficient power supply and improper workmanship may result in electric shocks or fire.
• Use a cable of suitable length. Do not use tapped wires or an extension lead, as this may cause overheating, electric shocks or fire.
• 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, fire or overheating terminals.
• Make sure that all wiring is secured, the specified wires are used, and that there is no strain on the terminal
connections or wires. Improper connections or securing of wires may result in abnormal heat build-up or fire.
• Install the air conditioner on a foundation strong enough to hold the weight of the unit.
A foundation of insufficient strength may result in the equipment falling and causing injury.
• When installing or relocating the air conditioner, do not let any other substances besides R32, such as air, enter the refrigerant circuit.
The presence of air or other foreign matter in the refrigerant circuit causes an abnormal pressure rise, which may result in equipment damage and even injury.
• If refrigerant gas leaks during installation, ventilate the area immediately.
Toxic gas may be produced if the refrigerant comes into contact with fire.
• 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 circuit breaker. Failure to install an earth leakage circuit breaker may result in electric shocks or fire.
• Do not use means to accelerate the defrosting process 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 flames,
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 floor area larger than 3.9m
2
.
• Comply with national gas regulations.
• During installation, attach the refrigerant piping securely before operating the compressor. If the refrigerant pipes are not attached and the stop valve is
open when the compressor is operated, air will be sucked in, causing abnormal pressure in the refrigeration cycle, which may result in equipment damage and even injury.
• During pump down, stop the compressor before removing the refrigerant piping. If the compressor is still operating 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.
Read the precautions in this manual
carefully before operating the unit.
This appliance is filled with R32.
• 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 fire, such as a fan heater, stove or cooker.

2-1. Caution on piping handling
1) Protect the open end of the pipe against dust and moisture.
2) All pipe bends should be as gentle as possible. Use a pipe
bender for bending.
2-2. Selection of copper and heat insulation materials
• When using commercial copper pipes and fittings, observe the following:
1) Insulation material: Polyethylene foam
Heat transfer rate: 0.041 to 0.052W/mK (0.035 to 0.045kcal/mh°C)
Refrigerant gas pipe’s surface temperature reaches 110°C max.
Choose heat insulation materials that will withstand this temperature.
2)
Be sure to insulate both the gas and liquid piping and observe the
insulation dimensions as below.
3) Use separate th
ermal insulation pipes for gas and liquid refrigerant pipes.
• Align the centres of both flares and tighten the flare nuts 3 or 4 turns by hand. Then tighten them fully
with the torque wrenches.
• Refrigerant oil for R410A can also be used for application to the inner flare.
•
Use the flare nut fixed to the main unit.
(This is to prevent cracking of the flare nut as a result of deterioration over time.)
•
To prevent gas leakage, apply refrigeration oil only to the inner surface of the flare.
(Use refrigeration oil for R32.)
•
Use a torque wrench when tightening the flare nuts to prevent damage to the flare nuts and gas leakage.
