SAFETY INSTRUCTIONS
ENGLISH
• The indoor/outdoor wiring connections must be secured tightly, and
the cable should be routed properly so that there is no force pulling the
cable from the connection terminals. Improper or loose connections
can cause heat generation or fire.
• Install dedicated electric outlet and circuit breaker before using the air
conditioner.
• Do not connect the ground wire to a gas pipe, a lightning rod, or a
telephone ground wire.
• Means for disconnection must be incorporated in the fixed wiring in
accordance with the wiring rules.
• Keep any required ventilation openings clear of obstruction. (for R32)
Operation
• Be sure to use only those parts listed in the service parts list. Never
attempt to modify the equipment.
• Make sure that children do not climb on or hit the outdoor unit.
• Dispose of the batteries in a place where there is no danger of fire.
• Use only the refrigerant specified on the air conditioner label.
