The phases on the terminal block are color coded:
• Red - PhaseL1
• Blue - PhaseL2
• None - PhaseL3
The CSHW compressor is designed for use with terminal
plugs.
Before starting the compressor, check the electrical
phasing with a phase sequence meter similar to an
Ideal-Sperry Model 61-520.
WARNING
Hazardous Service Procedures!
Failure to follow all instructions in this manual and on
the tags, stickers, and labels could result in death or
serious injury.
Technicians, in order to protect themselves from
