this manual.
WARNING
General
• Before starting to install the air conditioner, read through the Installation Manual carefully, and follow its
instructions to install the air conditioner.
• Only a qualified installer or service person is allowed to do installation work. Inappropriate installation
may result in water leakage, electric shock or fire.
• 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, 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 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 filter 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 work location, before
proceeding with the work. Parts and other objects may fall from above, possibly injuring a person below.
While carrying out the work, wear a helmet for protection from falling objects.
• 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 when removing the cover and main unit.
