During the recovery phase, the machine displays the quantity of refrigerant recovered, in
grams. Upon completion of recovery, the machine will stop and discharge, while automatically
displaying the used oil extracted from the A/C system during the recovery phase.
The oil discharge operation lasts 4 minutes.
The machine checks whether or not there is air in the tank and, if necessary, purges the non-
condensable gas; The machine will automatically discharge any non-condensable gas.
Allowing the machine to fully complete the procedure will reduce the risk of return flows, which
may cause excessive non-condensable gas to be recharged into the air conditioning system. If
any residual refrigerant in the A/C system should increase in pressure during this phase, the
machine will automatically begin recovering the refrigerant.
Completed the recovery phase, the machine automatically goes on to running the vacuum
phase for the preset time:
