1.1 SAFETY PRECAUTIONS
WARNING
This symbol indicates the possibility of personnel injury or loss of life.
Installing, starting up, and servicing air-conditioning equipment can be hazardous due to system
ressures, electrical components, and equipment location (roofs, elevated structures, etc.).
Only trained, qualified installers and service mechanics should install, start-up, and serve this equipment.
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 handing, 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 for special requirement.
Refrigerant gas is heavier than air and replaces oxygen.Amassive leak could lead to oxygen
depletion, especially in basements, and an asphyxiation hazard could occur leading to serious
injury or death.
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.
If the refrigerant gas leaks during installation, ventilate the area immediately.
Refrigerant gas may produce a toxic gas if it comes in contact with fire such as from a fan heater, stove or
cooking device.
Exposure to this gas could cause severe injury or death.
Disconnect from power source before attempting any electrical work. Connect the connective cable
correctly.
Wrongly connecting may result in electric parts damaged.
Use the specified cables for electrical connections and attach the wires firmly to the terminal block
connecting sections so that the external force is not exerted to the terminal.
Be sure to provide grounding.
Do not ground units to gas pipes, water pipes, lightning rods or telephone wires. Incomplete grounding
could cause a severe shock hazard resulting in injury or death.
Safely dispose of the packing materials.
Packing materials, such as nails and other matal or wooden parts, may cause stabs or other injuries. Tear
apart and throw away plastic pacaging bags so that children will not play with them. Children playing with
plastic bags face the danger of suffocation.
Do not install unit near concentrations of combustible gas or gas vapors.
Be sure to use the supplied or exact specified installation parts.
Use of other parts may cause the unit to come to lose, water leakage, electrical shock, fire or equipment
damage.
When installing or relocating the system, do not allow air or any substances other than the
specified refrigerant (R410A/R32) to enter the refrigeration cycle.
Never modify this unit by removing any of the safety guards or bypassing any of the safety
interlock switches.
Electrical work should be carried out in accordance with the installation manual and the national,
state and local electrical wiring codes.
Be sure to use a delicated power circuit. Never share the same power outlet with other appliance.
