A/C SYSTEM FLUSHING
A/C System Flushing procedure to be carried out using the
FLUSHING KIT. To carry out the procedure, it is necessary to have
at least 3 kg (7 lbs) of refrigerant available in the storage tank
(therefore excluding the minimum quantity).
At the beginning of the procedure, the machine requests the
amount of refrigerant to be used for each flushing cycle and the
data of the vehicle on which the procedure is being carried out
(VIN and license plate if activated) and then requests to connect
the service hoses to the flushing kit and to the A/C system.
Once these data have been confirmed, the machine carries out a
leak test of the system and connections which consists of a
vacuum and a pressure test with warning in case leaks are
detected.
If both tests are successful, the flushing cycles are started, each of
which includes an injection of refrigerant (according to the
quantity initially set) and a subsequent recovery. At the end of
the cycles, the accumulated oil is discharged and the machine
perform a final internal gas recovery.
For information on how to connect and use this option refer to
User manual [MANU109.NFK] provided with the flushing kit.
