windows more often than necessary.

Checks before operating
• Check whether the ground wires are properly connected.
• Check whether the air filters are installed.
• Turn on the leakage breaker at least 12 hours before operating.
Protective device
• The protective device stops operation when the air conditioner is
overloaded.

stops and the operation lamp and
flash.
When the protective device is activated
• When the protective device has been activated and stopped
operation, turn off the leakage breaker immediately, and ask the
installer to find the cause.
If the air conditioner is operated without fixing the problem, the air conditioner may malfunction.

If the air filters are not installed, the air heat exchanger may be clogged with dust, which may result in
water leakage.
