All refrigerant-cooled models listed for application "L" require an air blast against the body for motor cooling. Please specify body casting changes.

NOTE: When ordering obtain all information from nameplate on compressor; give model number, horsepower, voltage and phase.

4R and 6R compressors may have solid state motor protection. These can be identified by the control module in terminal box. Also, look for TSK at the end of the model number.

When 4R and 6R compressors have old style by-pass unloading, we recommend the new style unloaded heads be installed. There is an additional charge for these heads. Please advise whether 110V or 230V control solenoid are needed.
