Compressors and Starting Components

RS70 Compressor (example RS70C1E-PFV-213), used until mid June 2012. Refer to this parts list for
compressor service parts on units manufactured before serial number 12061320011941.

18-8768-22 Compressor 208-230/60/1
18-1901-54 Start Capacitor, 60 Hz
18-1902-45 Run Capacitor, 60 Hz
18-1903-33 Potential Relay 60 Hz

Overload is internal

18-8768-24 Compressor 208-230/60/3

Overload is internal
18-8772-26 Compressor 230/50/1
18-1901-53 Start capacitor, 50 Hz
18-1902-53 Run capacitor, 50 Hz
18-1903-29 Potential relay, 50 Hz
18-8772-21 Overload

Note: Replacement compressors include a new dryer, and single phase 60 Hz replacements include the
starting components.

Because the RST compressor is not an exact replacement for the RS, the kits below include the
tubing and starting components needed to install the RST compressor in place of the RS.

RST70 Compressor, (example RST70C1E-PFV) use began with serial number 12061320011941. Refer to

this parts list for compressor service parts on any unit after that serial number.

18-8955-22 Compressor 208-230/60/1
18-1901-20 Start Capacitor, 60 Hz
18-1902-67 Run Capacitor, 60 Hz
18-1903-54 Potential Relay 60 Hz

Overload is internal
18-8955-23 Compressor 208-230/60/3
18-8955-53 Overload

Note: Replacement compressors include a new dryer, and single phase 60 Hz replacements include the
starting components.

No 50 Hz RST compressor was used in production. Continue to use 18-8772-26 as a replacement for 50
Hz compressors in these models.
