Installation place

• Check that the air conditioner is not installed in a place subject to combustible gas leak.
Accumulation of combustible gas around the unit may cause a fire.
• Drain the dehumidified water from the indoor unit and outdoor unit to a well-drained place.
• Do not put any obstacle near the air inlets and air outlet of the outdoor unit.
Doing so may hinder the radiation, which may reduce the performance or activate the protective device.

Electrical wiring

• Be sure to connect earth 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.
• Make sure that a leakage breaker is connected.
Using the air conditioner without leakage breaker may cause electric shock.
• Use a leakage breaker with an appropriate capacity.
Be sure to use the rated voltage and an exclusive circuit for power supply of the air conditioner.
Do not install the air conditioner in the following places
• Do not install the air conditioner in any place within 1 m from a TV, stereo, or radio set.
If the unit is installed in such place, noise transmitted from the air conditioner affects the operation of these
appliances.
• Do not install the air conditioner near a high frequency appliance (sewing machine or massager for business use,

(in a hot-spring area or near a chemicals factory, or in a place subject to combustion emissions).
Corrosion may be generated on the aluminum fin and copper pipe of the heat exchanger.
• Do not install the air conditioner near an obstacle (air vent, lighting equipment, etc.) that disturbs discharge air.
(Turbulent airflow may reduce the performance or disable devices.)
• Do not use the air conditioner for special purposes such as preserving food, precision instruments, or art objects,
or where breeding animals or growing plants are kept. (This may degrade the quality of preserved materials.)
