GENERAL INFORMATION

Machine model information are printed on the data plate (see
Fig. 1). Overall machine dimensions:

Height: 47" (120 cm)
Width: 25" (64 cm)
Depth: 25" (64 cm)

Weight: 200 lbs (90 kg)

Operating temperature 50/122°F (10/50°C)
Storage temperature -13/122°F (-25/50°C)

PRINCIPLES OF OPERATION

In a single series of operations, the machine permits recovering
and recycling R134a refrigerant fluids with no risk of releasing the
fluids into the environment, and also permits purging the A/C
system of humidity and deposits contained in the oil.

The machine is in fact equipped with a built-in
evaporator/separator that removes oil and other impurities from
the refrigerant fluid recovered from the A/C system and collects
them in a container for that purpose.

The fluid is then filtered and returned perfectly recycled to the
tank installed on the machine.

The machine also permits running certain operational and seal
tests on the A/C system.

NAMEPLATE
