PRECAUTIONS FOR SAFETY

Installing, starting up, and servicing air--conditioning equipment can be hazardous due to system pressures,
electrical components, and equipment location (roofs, elevated structures, etc.).
Only trained, qualified installers and service mechanics should install, start--up, and service this equipment.
Untrained personnel can perform basic maintenance functions such as cleaning heat exchanger. All other
operations should be performed by trained service personnel.
When working on the equipment, observe precautions in the literature and on tags, stickers, and labels attached
to the equipment.
Follow all safety codes.Wear safety glasses and work gloves. Keep quenching cloth and fire extinguisher nearby
when brazing. Use care in handling, rigging, and setting bulky equipment.
Read these instructions thoroughly and follow all warnings or cautions included in literature and attached to the
unit. Consult local building codes and National Electrical Code (NEC) for special requirements. Recognize safety
information. This is the safety--alert symbol
manuals, be alert to the potential for personal injury.Understand these signal words: DANGER, WARNING, and
CAUTION. These words are used with the safety--alert symbol.
DANGER identifies the most serious hazards which will result in severe personal injury or death. WARNING
signifies hazards which could result in personal injury or death. CAUTION is used to identify unsafe practices which
may result in minor personal injury or product and property damage. NOTE is used to highlight suggestions which
will result in enhanced installation, reliability, or operation.
• Ask an authorized dealer or qualified installation professional to install (including moving)/maintain the air
conditioner.
Inappropriate installation may result in water leakage, electric shock or fire.
• Be sure to connect ground wire. (grounding work)
Incomplete grounding cause an electric shock.
Do not connect ground wires to gas pipes, water pipes, lightning rods or ground wires for telephone wires.
• Turn off the circuit breaker before attempting any electrical work.
Make sure all circuit breaker is off. Failure to do so may cause electric shock.
• Install the refrigerant pipe securely during the installation work before operating the air conditioner.
If the air conditioner is operated with the valve open and without the refrigerant pipe, the compressor sucks air and
the refrigeration cycle is overpressurized, which may cause a burst or injury.
• 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 resultingly causes pipe burst and injuries on persons.
• 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.
