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(*1) or qualified service person(*1) 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 specifled 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 front panel 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 front panel 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.
