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 aluminum 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.
7-EN
• 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.
• This unit is equipped with a refrigerant leak detection sensor for
safety, to be effective, the unit must be electrically powered at all
times after installation, other than when servicing. Turning off the
circuit breaker cause refrigerant leak detection sensor not to operate
and not to enable to detect refrigerant leaks, causing a fire.
• The refrigerant used by this air conditioner is the R32.
• 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 four
or more people.
• Servicing shall be performed only as recommended by the
manufacturer. 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.
• This appliance is intended to be used by expert or trained users in
shops, in light industry, or for commercial use by lay persons.
About the refrigerant R32
• The appliance shall be stored in a room without continuously
operating ignition sources (for example: open flames, an operating
gas appliance or an operating electric heater).
• Do not pierce or burn refrigerant cycle parts.
• Do not use means to accelerate the defrosting process or to clean,
other than those recommended by the manufacturer.
• Be aware that refrigerants may not contain an odor.
• Pipe-work shall be protected from physical damage.
• Compliance with national gas regulations shall be observed.
• If refrigerant leak detection sensor detects R32 refrigerant leak, a fan
on indoor unit automatically operates to stir an air in the room. Stirring
air flow volume of each model is as shown below.
