Installation Manual

EN-6

of conventional refrigerant (R22). Use the specified pipe parts, and 
ensure correct installation, otherwise damage and/or injury may be 
caused. At the same time, water leakage, electrical shock, and fire 
may occur.

• Be sure to install the unit in a place which can sufficiently bear its 

weight. If the load bearing of the unit is not enough, or installation 
of the unit is improper, the unit may fall and result in injury.

• Electrical work must be performed by a qualified electrical engineer 

in accordance with the code governing such installation work, 
internal wiring regulations, and the manual. A dedicated circuit and 
the rated voltage must be used. Insufficient power supply or 
improper installation may cause electrical shock or fire.

• Use a cabtyre cable to connect wires in the indoor/outdoor units. 

Midway connection, stranded wire, and single-wire connections are 
not allowed. Improper connection or fixing may cause a fire.

• Wiring between the indoor unit and outdoor units must be well 

shaped so that the cover can be firmly placed. Improper cover 
installation may cause increased heat, fire, or electrical shock at 
the terminal area.

• Be sure to use only approved accessories or the specified parts. 

Failure to do so may cause the unit to fall, water leakage, fire or 
electrical shock.

• After the installation work, ensure that there is no leakage of 

refrigerant gas. If the refrigerant gas leaks out of the pipe into the 
room and is heated by fire or something else from a fan heater, 
stove or gas range, it causes generation of poisonous gas.

• Make sure the equipment is properly earthed. Do not connect the 

earth wire to a gas pipe, water pipe, lightning conductor, or 
telephone earth wire. Improper earth work may be the cause of 
electrical shock.

• Do not install the unit where flammable gas may leak. If there is 

any gas leakage or accumulation around the unit, it can cause a 
fire.

• Do not select a location for installation where there may be 

excessive water or humidity, such as a bathroom. Deterioration of 
insulation may cause electrical shock or fire.

• Installation work must be performed following the instructions in 

this installation manual. Improper installation may cause water 
leakage, electrical shock or fire. Check the following items before 
operating the unit.
- Be sure that the pipe connection is well placed and there are no 

leaks.

- Check that the service valve is open. If the service valve is 

closed, it may cause overpressure and result in compressor 
damage. At the same time, if there is a leak in the connection 
part, it may cause air suction and overpressure, resulting burst or 
injury.

• In pump down operations, ensure to perform the following 

procedures.
- Do not inject air into the refrigeration cycle.
- Be sure to close both service valves and stop the compressor 

before removing the refrigerant pipe. If removing the refrigerant 
pipe while the compressor is operating with the service valves 
opened, it may cause to air absorbed and abnormal high 
pressure inside the refrigeration cycle and resulting burst or 
injury.

• Do not modify the power cable, connect the cable midway, or use a 

multiple outlet extension cable. Doing so may cause contact failure, 
insulation failure, or excess current, resulting in fire or electrical 
shock.

• Do not use any refrigerant different from the one specified for 

complement or replacement. Otherwise, abnormally high pressure 
may be generated in the refrigeration cycle, which may result in a 
failure or explosion of the product or an injury to your body.

• Be sure to comply with local regulations/codes when running the 

wire from the outdoor unit to the indoor unit. (Size of wire and
