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 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.
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 in a location where flammable gas leaks are possible. If the gas leak and accumulate around the unit,
it may ignite and cause a fire.
• 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.
• Install the indoor unit at least 2.5 m above the floor level since otherwise the users may injure themselves or receive
electric shocks if they poke their fingers or other objects into the indoor unit while the air conditioner is running.
• 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
• When the indoor unit is to be suspended, the designated hanging bolts (M10 or W3/8) and nuts (M10 or W3/8) must
be used.
• 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 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 or other trouble.
