General Description

CAUTION: NEVER CHARGE THE A/C SYSTEM THROUGH THE HIGH PRESSURE SIDE OF THE SYSTEM. COMPONENT DAMAGE AND PERSONAL INJURY COULD RESULT.

NOTE: Under no circumstances should alcohol be used in the system in an attempt to remove moisture. Damage to the system components could occur.


If the system has been opened for any repair, or the R-134a charge lost, the system must be evacuated prior to charging.

Evacuation and charging is a combined procedure and all gauge lines must be purged with R-134a prior to charging.
