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.
• Do not undertake inspections or servicing with all the hooks of the center panel disengaged and with only one or
two wires still attached to the center panel. Doing so may cause the center panel to fall down, possibly causing
injury to any individuals below.
• Wear protective gloves and safety work clothing during installation, servicing and removal.
• Do not touch the aluminium fin of the outdoor 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.
• 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.
