• Install a circuit breaker. For safety and maintenance, we strongly recommend that
MCCB, ELB and ELCB have to be installed every outdoor unit.
- ELCB : Earth Leakage Circuit Breaker
- MCCB : Molded Case Circuit Breaker
- ELB : Earth Leakage fuse Breaker
• Operate the unit after the refrigerant piping work must be done.
• Do not disassemble or alter the wiring of the unit during the electrical wiring work.
If not, the unit may be damaged.
