Defi nition of protective gear
When the air conditioner is to be transported, installed, maintained, repaired or removed, wear protective gloves and
‘safety’ work clothing.
In addition to such normal protective gear, wear the protective gear described below when undertaking the special
work detailed in the table below.
Failure to wear the proper protective gear is dangerous because you will be more susceptible to injury, burns, electric
shocks and other injuries.
WARNING
General
• Before starting to install the air conditioner, read carefully through the Installation Manual, and follow its instructions
to install the air conditioner.
• Only a qualifi ed installer(*1) or qualifi ed service person(*1) is allowed to install the air conditioner. If the air
conditioner is installed by an unqualifi ed individual, a fi re, electric shocks, injury, water leakage, noise and/or
vibration may result.
• Do not use any refrigerant different from the one specifi ed 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.
• Before opening the front panel of the indoor unit or service panel of the outdoor unit, set the circuit breaker to the
OFF position. Failure to set the circuit breaker to the OFF position may result in electric shocks through contact with
the interior parts. Only a qualifi ed installer(*1) or qualifi ed service person(*1) is allowed to remove the front panel of
the indoor unit or service panel of the outdoor unit and do the work required.
• Before carrying out the installation, maintenance, repair or removal work, be sure to set the circuit breaker to the
OFF position. Otherwise, electric shocks may result.
• Place a “Work in progress” sign near the circuit breaker while the installation, maintenance, repair or removal work
is being carried out. There is a danger of electric shocks if the circuit breaker is set to ON by mistake.
• Wear protective gloves and safety work clothing during installation, servicing and removal.
• Do not touch the aluminum fi n of the unit. You may injure yourself if you do so. If the fi n must be touched for some
reason, fi rst put on protective gloves and safety work clothing, and then proceed.
• The refrigerant used by this air conditioner is the R410A.
Selection of installation location
• If you install the unit in a small room, take appropriate measures to prevent the refrigerant from exceeding the limit
concentration even if it leaks. Consult the dealer from whom you purchased the air conditioner when you implement
the measures. Accumulation of highly concentrated refrigerant may cause an oxygen defi ciency accident.
• Do not install the air conditioner in a location that may be subject to a risk of exposure to a combustible gas. If a
combustible gas leaks and becomes concentrated around the unit, a fi re may occur.
• 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 a 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.
