Installation Manual

‒

7-EN

• Install the indoor unit at least 8

′

2

″

(2.5 m) above the

fl

oor level since

otherwise the users may injure themselves or receive electric shocks if
they poke their

fi

ngers or other objects into the indoor unit while the air

conditioner is running.

Installation

• 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.

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

immediately. If the leaked refrigerant gas comes in contact with

fi

re, 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

fl

are nut with a torque wrench in the speci

fi

ed manner.

Over tightening of the

fl

are nut may cause a crack in the

fl

are nut after a long

period, which may result in refrigerant leakage.

• After the installation work, con

fi

rm that refrigerant gas does not leak.

If refrigerant gas leaks into the room and

fl

ows near a

fi

re 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.

Electrical wiring

• Only a quali

fi

ed installer or quali

fi

ed service person is allowed to carry out

the electrical work of the air conditioner. Under no circumstances must this
work be done by an unquali

fi

ed individual since failure to carry out the work

properly may result in electric shocks and/or electrical leaks.
