• When transporting the air conditioner, wear shoes with additional protective
toe caps.
• 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
• Install the air conditioner at enough strong places to withstand the weight
of the unit. 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, etc.
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 fl are nut with a torque wrench in the specifi ed manner. Excessive
tighten 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 or servicing work, confi 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.
• 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 be generated.
Electrical wiring
• Only a qualifi ed installer(*1) or qualifi ed 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 unqualifi ed individual since failure to carry out the
work properly may result in electric shocks and/or electrical leaks.
• When connecting the electrical wires, repairing the electrical parts or
undertaking other electrical jobs, wear gloves to provide protection for
electricians and from heat, 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 specifi cations in the Installation Manual and the
stipulations in the local regulations and laws. Use of wiring which does not
meet the specifi cations may give rise to electric shocks, electrical leakage,
smoking and/or a fi re.
