• 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 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 two
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.
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.

0.6 m for floor standing / 1.8 m for wall mounted / 1.0 m for window
mounted / 2.2 m for ceiling mounted.
For detail, refer to Installation Manual of the outdoor unit.
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.
• Carry out the specified installation work to guard against the
possibility of high winds and earthquake. If the air conditioner is not
installed appropriately, a unit may topple over or fall down, causing an
accident.
• If refrigerant gas has leaked during the installation work, ventilate the
room immediately. If the leaked refrigerant gas comes in contact with
fire, noxious gas may generate.
• Use forklift to carry in the air conditioner units and use winch or hoist
at installation of them.
Refrigerant piping
• Install the refrigerant pipe securely during the installation work before
operating the air conditioner. If the compressor is operated with the
valve open and without refrigerant pipe, the compressor sucks air and
the refrigeration cycles is over pressurized, which may cause an
injury.
• Tighten the flare nut with a torque wrench in the specified manner.
Excessive tighten of the flare nut may cause a crack in the flare nut
after a long period, which may result in refrigerant leakage.
• After the installation work, confirm that refrigerant gas does not leak.
If refrigerant gas leaks into the room and flows near a fire source,
such as a cooking range, noxious gas may be generated.
