Introduction
This manual contains important safety procedures concerning the opera-
tion, use and maintenance of this product. Failure to follow the instruc-
tions contained in this manual may result in serious injury. If you are

The 342000 is a complete air conditioning service center for R-134a. It recovers,
recycles, evacuates, and recharges refrigerant quickly, accurately and
automatically, with little attention needed from the technician. A microprocessor
controls the unit’s functions and prompts on the display lead you through the
operation. These prompts are written so they are easy to understand and follow.
The entire service procedure can be done with one hook-up to the vehicle. A
built-in refrigerant identifier checks for contaminated refrigerant prior to recovery.
Pressures are shown on the high and low side gauges, and other operating
information is shown on the display.
Refrigerant is recovered into and charged out of an internal storage vessel (ISV).
The 342000 unit automatically refills this vessel with refrigerant from an external
source tank as needed in order to maintain a constant 12 –15 lbs. (5.45 – 6.82 kgs)
of refrigerant available to be charged. Quick connections are all that’s needed to
replace the source tank when it’s empty.
Other time-saving features include automatic air purge, single pass recycling, and
automatic oil drain. The unit also automatically clears refrigerant after every job. A
red light on the top of the unit flashes whenever a process is complete or when the
unit needs attention from the user.
The 342000 is UL listed and meets SAE specifications for recycled refrigerant.
