PRINCIPLES OF OPERATION

In a single series of operations, the machine permits recovering and recycling refrigerant fluids
(R134a or R1234yf, depending on machine model) 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
bottle installed on the machine. The machine also permits running certain operational and seal
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 RED quick-connect coupling on the male threaded
connector indicated by the RED HIGH PRESSURE symbol. Referring to Figure 4, remove the
protection under the refrigerant scale as follows::
- Loosen the nut [2].
- Completely loosen the screw [1].
- Keep the screw [1], the nut [2], and the knurled washer [4] for possible future use.
NOTE: in the event that the equipment has to be transported, the refrigerant bottle scale should
be locked in place as follows:
- Procure two size 10 wrenches.
- Tighten the nut [2] almost completely onto the screw [1].
- Insert the knurled washer [4] onto the screw [1].
- Turn the screw [1] just a few times on the threaded bush [6].
- Switch the machine on.
- Tighten the screw [1] until the display signals ZERO availability.
- Tighten the nut [2] forcefully (using the second wrench to block the screw [1]).
- Check that the screw [1] is actually locked, if necessary repeat the locking operation
from the beginning.
