Operating Instructions
OPERATING TIPS
Follow the SAE-J1991 recommended service procedure for the containment of
R-12, and the SAE-J2210 recommended service procedure for the containment of
R-134a.
The recovery compressor is not a vacuum pump. The compressor pulls the A/C
system to a partial vacuum only. You must use the unit’s vacuum cycle to remove
moisture from the A/C system. We recommend a minimum 15-minute vacuum, or
follow the system manufacturer's recommendations.
This unit is designed to be used with the manifold gauge set built into the
control panel.
The unit includes a 6 cfm (142 l/m) Robinair high vacuum pump for fast, thorough
evacuation. Change the vacuum pump oil after every 10 hours of use.
R-134a systems require special oils. Refer to the A/C system manufacturer’s
service manuals for oil specifications.
Pressing the START and STOP keys together for several seconds will exit any
mode and reset the control.
NOTE: The following operating instructions are written to be used with the
BASIC PROMPTS mode of operation. It is recommended that the BASIC
PROMPTS mode is used until the operator becomes very familiar with the
operation of the unit. See the OPERATING GUIDELINES section of this manual
for instructions on how to select between BASIC PROMPTS and ADVANCED
PROMPTS.
