ing, or leakage of water. 

 When installing the unit, use appropriate protective equipment and tools for 

safety.

  Failure to do so could cause injury.

  Install the unit securely in a place that can bear the weight of the unit.

  If the installation location cannot bear the weight of the unit, the unit could fall 

causing injury.

  Do not alter the unit.

■ 

Perform electrical work according to the installation manual and be sure to use 

an exclusive circuit. Do not connect other electrical appliances to the circuit.

  Ground the unit correctly.

  Do not connect the ground wire to a gas pipe, water pipe, lightning rod or 

telephone ground. Defective grounding could cause electric shock.

  If required, take measures against leakage current.

■ 

Do not damage the wires.

■ 

Be sure to shut off the main power when setting up the indoor P.C. board or 

wiring.

  Failure to do so could cause electric shock.

  If gas leaks and accumulates around the unit, it could cause an explosion.

  Do not use intermediate connection of the power cord or the extension cord.

Do not connect many devices to one AC outlet.

■ 

When plugging the power supply plug into the outlet, make sure that there is 

no dust, blockage, or loose parts both in the outlet and on the plug. Verify that 

the power supply plug is completely in the outlet.

Securely attach the electrical cover to the indoor unit and the service panel to 

the outdoor unit.

■ 

When installing, relocating, or servicing the unit, make sure that no substance 

RWKHUWKDQWKHVSHFL¿HGUHIULJHUDQW5$HQWHUVWKHUHIULJHUDQWFLUFXLW

  Any presence of foreign substance such as air can cause abnormal pressure rise 

and may result in explosion or injury. The use of any refrigerant other than that

breakdown. In the worst case, this could lead to a serious impediment to securing 

product safety.

■ 

Do not discharge the refrigerant into the atmosphere. Check that the refriger-

ant gas does not leak after installation has been completed. If refrigerant leaks 

during installation, ventilate the room.

heater, space heater, stove, etc., harmful gases will be generated.

■ 

Use appropriate tools and piping materials for installation. 

  The pressure of R410A is 1.6 times higher than R22. Not using the appropriate 

tools and materials, or improper installation could cause the pipes to burst causing 

an injury. 

■ 

When pumping down the refrigerant, stop the compressor before disconnecting 

the refrigerant pipes.

  If the refrigerant pipes are disconnected while the compressor is running and the 

stop valve is open, air could be drawn in and the pressure in the refrigeration cycle 

could become abnormally high, causing the pipes to burst. 

■ 

When installing the unit, securely connect the refrigerant pipes before starting 

the compressor.

  If the compressor is started before the refrigerant pipes are connected and the 

stop valve is open, air could be drawn in and the pressure in the refrigeration cycle 

could become abnormally high, causing the pipes to burst.

■ 

Install the unit  according to national wiring regulations.

■ 

When opening or closing the valve below freezing temperatures, refrigerant may 

spurt out from the gap between the valve stem and the valve body, resulting in 

injuries.

 Please follow applicable federal, state, or local codes to prevent potential 

leakage/electric shock. Or install a ground fault interrupt for the prevention of 

leakage and electric shock.

  Perform the drainage/piping work securely according to the installation manual.

  If there is defect in the drainage/piping work, water could drip from the unit, and 

damage household items.

  This could cause injury. 

  Do not install the outdoor unit where small animals may live.

  If small animals enter the unit and damage its electrical parts, it could cause a
