Introduction - Bosch ACS 753 Repair Instructions

ACS 753, ACS 763, ACS 863 Service Manual
These units are designed to be compatible with existing service equipment and standard service
procedures. These machines utilize a single-pass system that meets specifications for recycled
refrigerant. Follow recommended service procedures for the containment of refrigerant.
Each unit includes a high-vacuum pump for fast, thorough evacuation. The compressor first pulls
the A/C system to -0.4 bar; the compressor then works with the vacuum pump to pull a vacuum
to an absolute pressure of less than 1.0 bar.
NOTE: Refrigerant systems require special oils. Refer to the A/C system manufacturer's service
manual for oil specifications.
