the Manufacturer are such that during work, the average noise level of the machine is less than 70 dB (A).
NOTE: The machine is intended for indoor use only.

PRINCIPLES OF OPERATION

In a single series of operations, the machine permits recovering and recycling refrigerant with no risk of release into the environment, and also
permits purging the A/C system of humidity and deposits contained in the oil. The machine is equipped with a built-in evaporator/separator that
removes oil and other impurities from the refrigerant recovered from the A/C system and collects them in a container for that purpose. The fluid is
then filtered, recycled and returned to the tank installed in the machine. The machine also permits running certain operational and leak tests on the
A/C system.

SETUP

The machine is supplied fully assembled and tested. Referring to Figure 3, mount the
hose with the BLUE quick-connect coupling on the male threaded connector indicated by
the BLUE LOW PRESSURE symbol and the hose with the RED quick-connect coupling on
the male threaded connector indicated by the RED HIGH PRESSURE symbol.
