• When work is performed at heights, use a ladder which complies with 

the ISO 14122 standard, and follow the procedure in the ladder’s 

instructions. Also wear a helmet for use in industry as protective gear 

to undertake the work.

• Before cleaning the filter or other parts of the outdoor unit, set the 

circuit breaker to OFF without fail, and place a “Work in progress” sign 

near the circuit breaker before proceeding with the work.

• Before working at heights, put a sign in place so that no-one will 

approach the work location, before proceeding with the work. Parts 

and other objects may fall from above, possibly injuring a person 

below. While carrying out the work, wear a helmet for protection from 

falling objects.

• The refrigerant used by this air conditioner is the R410A.

• The air conditioner must be transported in stable condition. If any part 

of the product is broken, contact the dealer.

• When the air conditioner must be transported by hand, carry it by two 

or more people.

• Do not move or repair any unit by yourself. There is high voltage 

inside the unit. You may get electric shock when removing the cover 

and main unit.

• This appliance is intended to be used by expert or trained users in 

shops, in light industry, or for commercial use by lay persons.

Selection of installation location

• When the air conditioner is installed in a small room, provide 

appropriate measures to ensure that the concentration of refrigerant 

leakage occur in the room does not exceed the critical level.

• Do not install in a location where flammable gas leaks are possible. If 

the gas leak and accumulate around the unit, it may ignite and cause 

a fire.

• To transport the air conditioner, wear shoes with additional protective 

toe caps.

• To transport the air conditioner, do not take hold of the bands around 

the packing carton. You may injure yourself if the bands should break.

• Install the indoor unit at least 2.5 m above the floor level since 

otherwise the users may injure themselves or receive electric shocks 

if they poke their fingers or other objects into the indoor unit while the 

air conditioner is running.

• Do not place any combustion appliance in a place where it is directly 

exposed to the wind of air conditioner, otherwise it may cause 

imperfect combustion.

Installation

• When the indoor unit is to be suspended, the designated hanging 

bolts (M10 or W3/8) and nuts (M10 or W3/8) must be used.

• Install the air conditioner securely in a location where the base can 

sustain the weight adequately. If the strength is not enough, the unit 

may fall down resulting in injury.

• Follow the instructions in the Installation Manual to install the air 

conditioner. Failure to follow these instructions may cause the 

product to fall down or topple over or give rise to noise, vibration, 

water leakage or other trouble.

• Carry out the specified installation work to guard against the 

possibility of high winds and earthquake. If the air conditioner is not 

installed appropriately, a unit may topple over or fall down, causing an 

accident.

• If refrigerant gas has leaked during the installation work, ventilate the 

room immediately. If the leaked refrigerant gas comes in contact with 

fire, noxious gas may generate.

• Use forklift to carry in the air conditioner units and use winch or hoist 

at installation of them.

Refrigerant piping

• 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 refrigerant pipe, the compressor sucks air and 

the refrigeration cycles is over pressurized, which may cause a injury.

• Tighten the flare nut with a torque wrench in the specified manner. 

Excessive tighten of the flare nut may cause a crack in the flare nut 

after a long period, which may result in refrigerant leakage.

• After the installation work, confirm that refrigerant gas does not leak. 

If refrigerant gas leaks into the room and flows near a fire source, 

such as a cooking range, noxious gas may be generated.

• When the air conditioner has been installed or relocated, follow the 

instructions in the Installation Manual and purge the air completely so 

that no gases other than the refrigerant will be mixed in the 

refrigerating cycle. Failure to purge the air completely may cause the 

air conditioner to malfunction.

• Nitrogen gas must be used for the airtight test.

• The charge hose must be connected in such a way that it is not slack.
