3Check that the ground is connected correctly.
CAUTION: Ground the unit.
Do not connect the ground to a gas pipe, water pipe, lightning rod or the ground of a telephone. If the grounding is incorrect, it may cause an electric shock.
Before starting maintenance
■Turn off the breaker.
CAUTION:
When the unit is to be cleaned, switch it off and turn off the breaker. Since the fan rotates at high speed during operation, it may cause an injury.
Cleaning the indoor unit
