NOTES
1. Order appropriate power wire while following national laws and standards for the insulating sheath,
thickness, and length.
2. When installing wiring in a location that can easily come in contact with people, be sure to install an earth
leakage breaker to prevent electric shock.
3. The earth leakage breaker must be a high-speed type breaker of 30mA(<0.1S).
4. Use an earth leakage breaker that can also be used as earth leakage, overload, short-circuit protection.
Be sure to use earth leakage breakers dedicated for earth leakage protection in combination with the load
break switch with fuse or breaker for wiring.
〈 CAUTION 〉
To the electrician
Do not run the unit until the refrigerant piping is complete, as not waiting could break the compressor.
