Precautions for Safety
The manufacturer shall not assume any liability for the damage caused
by not observing the description of this manual.
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 qualified installer(*1) or qualified service person(*1) is allowed
to install the air conditioner. If the air conditioner is installed by an
unqualified individual, a fire, electric shocks, injury, water leakage,
noise and/or vibration may result.
• Do not use any refrigerant different from the one specified 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 intake grille 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 qualified
installer(*1) or qualified service person(*1) is allowed to remove the
intake grille 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 qualified installer(*1) or qualified service person(*1) is allowed
to undertake work at heights using a stand of 50 cm or more or to
remove the intake grille of the indoor unit to undertake work.
• Wear protective gloves and safety work clothing during installation,
servicing and removal.
• Do not touch the aluminium fin of the unit. You may injure yourself if
you do so. If the fin must be touched for some reason, first put on
protective gloves and safety work clothing, and then proceed.

• Do not climb onto or place objects on top of the outdoor unit. You may
fall or the objects may fall off of the outdoor unit and result in injury.
• When working 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.
• When cleaning the filter or other parts, set the circuit breaker to OFF
without fail, and place a "Work in progress" sign near the circuit
breaker before proceeding with the work.
• When working at heights, put a sign in place so that no-one will
approach the work location, before proceeding with the work. Parts
and other objects may fall from above, possibly injuring a person
below. Furthermore, while carrying out the work, wear a helmet for
protection from falling objects.
• The refrigerant used by this air conditioner is the R410A.
• You shall ensure that the air conditioner is transported in stable
condition. In case an accident such as dropping of the unit occurs
while transporting the air conditioner, 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 when 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
• 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 deficiency
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 fire may occur.
• When transporting the air conditioner, wear shoes with additional
protective toe caps.
• When transporting the air conditioner, do not take hold of the bands
around the packing carton. You may injure yourself if the bands
should break.
