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 qualied installer or qualied service person is allowed to
do installation work. Inappropriate installation may result in water
leakage, electric shock or re.
• Do not use any refrigerant different from the one specied 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 qualied installer(*1) or qualied 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 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 intake grille of the indoor unit to
