Why Upgrade from the York Compressor?

The original York piston compressor is heavy, inefficient, and parts are increasingly scarce. The Sanden rotary compressor offers:

• Less engine load — lighter weight means less parasitic drag
• Better cooling efficiency — especially at low RPMs during field work
• R134a compatibility — works with the modern, readily available refrigerant standard
• Widely serviceable — any shop with modern A/C equipment can service a Sanden system

Installation Notes

• Flush the system thoroughly before installing to remove residual mineral oil from the original York compressor
• Use PAG oil specified for the Sanden compressor — do not mix with old mineral oil
• Replace all O-rings with HNBR (green) O-rings rated for R134a (included in kit)
• Install the included service valve adapters to enable R134a service equipment connection
• Have the system professionally evacuated and recharged with R134a refrigerant
