Installation Manual
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.
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 a 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.
• When the air conditioner has been installed or relocated, follow the instructions in the Installation
Manual and purge the air completely so that no gases other than the refrigerant will be mixed in the
refrigerating cycle. Failure to purge the air completely may cause the air conditioner to malfunction.
• Nitrogen gas must be used for the airtight test.
• The charge hose must be connected in such a way that it is not slack.
