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.
5. RZR48MUYMK is only 50Hz model.
〈 CAUTION 〉
To the electrician
Do not run the unit until the refrigerant piping is complete, as not waiting could break the compressor.
