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
toecap.
• 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.
• 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.
• Pay attention to the floor area in the room to be installed. The unit
cannot be installed in the room with floor area less than minimum floor
area described in Appendix of this Installation Manual.
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.
• 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 be generated, which may catch a fire.
• Use forklift to carry in the air conditioner units and use winch or hoist
at installation of them.
• The installation of pipe work shall be kept to a minimum.
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 an
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, which may
catch a fire.
• 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 Qualified installer (*1) or Qualified service person (*1) is
allowed to carry out the electrical work of the air conditioner. Under
no circumstances must this work be done by an unqualified individual
since failure to carry out the work properly may result in electric
shocks and/or electrical leaks.
• To connect the electrical wires, repair the electrical parts or undertake
other electrical jobs, wear gloves to provide protection for electricians
insulating shoes and clothing to provide protection from electric
shocks. Failure to wear this protective gear may result in electric
shocks.
• Use wiring that meets the specifications in the Installation Manual and
the stipulations in the local regulations and laws. Use of wiring which
does not meet the specifications may give rise to electric shocks,
electrical leakage, smoking and/or a fire.
• Connect earth wire. (Grounding work)
Incomplete earthing causes an electric shock.
• Do not connect earth wires to gas pipes, water pipes, and lightning
conductor or telephone earth wires.
• After completing the repair or relocation work, check that the earth
wires are connected properly.
• Install a circuit breaker that meets the specifications in the Installation
Manual and the stipulations in the local regulations and laws.
• Install the circuit breaker where it can be easily accessed by the
agent.
• When installing the circuit breaker outdoors, install one which is
designed to be used outdoors.
