Precautions for safety
The manufacturer shall not assume any liability for the damage caused
by not observing the description of this manual.
When connecting to an outdoor unit that uses R32 refrigerant, be sure
to read the warnings and cautions in “Precautions for using R32
refrigerant”.
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 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.
