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 quali
ed installer(*1) or quali
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.
• Only a quali
ed installer(*1) or quali
ed service person(*1) is allowed to
undertake work at heights using a stand of 50 cm or more or to remove the
front panel of the indoor unit to undertake work.

• 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
lter 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 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 while 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 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
re may occur.
• 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.
• 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.
• Do not install in a location where
ammable gas leaks are possible. If the
gas leak and accumulate around the unit, it may ignite and cause a
re.
• Install the indoor unit at least 2.5 m above the
oor level since otherwise
the users may injure themselves or receive electric shocks if they poke
their
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
