WARNING
• Ask an authorized dealer or qualified installation professional to install/maintain the air conditioner.
Inappropriate installation may result in water leakage, electric shock or fire.
• Turn off the main power supply switch or breaker before attempting any electrical work.
Make sure all power switches are off. Failure to do so may cause electric shock.
• Connect the connecting wire correctly.
If the connecting wire is connected in a wrong way, electric parts may be damaged.
• Be sure to connect the earth wire.
When the earth work is incomplete, an electrical shock may be caused.
(Never connect the earth wire to gas pipe, water pipe, lightning rod, earth wire of telephone, and etc.)
• When moving the air conditioner for the installation into another place, be very careful not to enter
any gaseous matter other than the specified refrigerant into the refrigeration cycle.
If air or any other gas is mixed in the refrigerant, the gas pressure in the refrigeration cycle becomes abnormally
high and it as a result causes pipe burst and injuries on persons.
• Do not modify this unit by removing any of the safety guards or by by-passing any of the safety
interlock switches.
• Exposure of unit to water or other moisture before installation may cause a short-circuit of electrical
parts.
Do not store it in a wet basement or expose to rain or water.
• After unpacking the unit, examine it carefully if there are possible damage.
• Hold the hanging brackets (4 positions) and do not apply force to other parts, especially the
refrigerant pipe or the drain pipe.
• Do not install in a place that might increase the vibration of the unit.
• To avoid personal injury (with sharp edges), be careful when handling parts.
• Perform installation work properly according to the Installation Manual.
Inappropriate installation may result in water leakage, electric shock or fire.
• 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.
• Install the air conditioner securely in a location where the base can sustain the weight
adequately.
• Perform the specified installation work to guard against an earthquake.
If the air conditioner is not installed appropriately, accidents may occur due to the falling unit.
• 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.
• 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 might
generate.
• Electrical work must be performed by a qualified electrician in accordance with the Installation
Manual. Make sure the air conditioner uses an exclusive power supply.
An insufficient power supply capacity or inappropriate installation may cause fire.
• Use the specified wires for wiring connect the terminals securely fix.
To prevent external forces applied to the terminals from affecting the terminals.
• Conform to the regulations of the local electric company when wiring the power supply.
Inappropriate grounding may cause electric shock.
• Do not install the air conditioner in a location subject to a risk of exposure to a combustible gas.
If a combustible gas leaks, and stays around the unit, a fire may occur.
