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.
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 tel-
ephone ground. Defective grounding could cause electric shock.
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.

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