Operating Instructions
OPERATING TIPS
Follow the recommended service procedure for the containment of R-12 and 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 with
more time as required by the system manufacturer.
This unit is designed to be used with the manifold gauge set built into the control
panel.
It includes a 6 cfm (142 l/m) vacuum pump for fast, thorough evacuation. Be sure to
change the vacuum pump oil after 10 hours of vacuum pump use.
R-12 and R-134a systems require special oils. Refer to the A/C system manufacturer’s
service manuals for oil specifications.
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.
