Caution
Except for EMERGENCY, never turn off main as well as sub breaker of the indoor units during 
operation. It will cause compressor failure as well as water leakage.
First, stop the indoor unit by operating the control unit or external input device and then cut the 
breaker.
Make sure to operate through the control unit or external input device.
When the breaker is designed, locate it at a place where the users cannot start and stop in an 
ordinary manner.
Regulation of wire size and circuit breaker differs from each locality, please refer to and be in 
accordance with local rules.
