• Do not move or repair any unit by yourself. Must be done by
qualified installer or qualified service person. Special precaution
should be taken when removing the cover for the unit to avoid
electric snock from high voltage lines.
• 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.
Flammable gas accumulation 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 8'2" (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.

Installation
• Suction duct length must be longer than 33.46" (850 mm).
• 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.
• 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.
• Helmet must be worn to protect your head from falling objects.
Especially, when you work under an inspection opening, helmet must
be worn to protect your head from falling objects from the opening.
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.
Over tightening 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.
