Installation Manual
WARNING
• When the air conditioner cannot cool or heat a room well, contact the dealer from whom you purchased the
air conditioner as refrigerant leakage is considered as the cause.
In the case of repair that requires refill of refrigerant, ask service personnel about details of the repair.
The refrigerant used in the air conditioner is harmless.
Generally, the refrigerant does not leak. However, if the refrigerant leaks in a room and a heater or stove burner in
the room catches fire, it may generate toxic gas.
When you ask service personnel for repairing refrigerant leakage, confirm that the leakage portion has been
completely repaired.
• Do not install the air conditioner in a location that may be subjected to a risk of exposure to a combustible
gas.
If a combustible gas leaks and becomes concentrated around the unit, a fire may occur.
• Install the refrigerant pipe securely during the installation work before operating the air conditioner.
If the compressor is operated with the valve open and without the refrigerant pipe, the compressor sucks air and the
refrigeration cycle is over pressurized, which may cause a burst or injury.
• When carrying out the pump-down work, shut down the compressor before disconnecting the refrigerant
pipe.
Disconnecting the refrigerant pipe with the service valve left open and with the compressor still operating will cause
air, etc. to be sucked in, raising the pressure inside the refrigeration cycle to an abnormally high level, and possibly
resulting in rupturing, injury, etc.
CAUTION
• Do not climb onto or place objects on top of the outdoor unit.
You may fall or the objects may fall off of the outdoor unit and result in injury.
• Wear heavy gloves during the installation work to avoid injury.
EQUIPMENT DAMAGE HAZARD
Failure to follow this caution may result in equipment damage or improper operation.
Do not bury more than 36 in. (914 mm) of refrigerant pipe in the ground. If any section of pipe is buried, there must be
a 6 in. (152 mm) vertical rise to the valve connections on the outdoor units. If more than the recommended length is
buried, refrigerant may migrate to the cooler buried section during extended periods of system shutdown. This causes
refrigerant slugging and could possibly damage the compressor at start-up.
