with the passenger compartment fan at full speed. Switch off the vehicle engine.
From ASSISTED PROCEDURE, the following screen will be displayed:
Press F4 ↵ to confirm "Recovery/Recycling," a pop-up window will be displayed:
Press F1 ↵ to confirm "Recovery/Recycling." The following screen will be displayed:
Type the plate of the car, use RIGHT ARROW → and LEFT ARROW ← to move inside plate number; press F4 ↵ to confirm.
NOTE: The numerical keys include an alphabet that is used similar to text messaging; for example: press "2" once to display "A", twice to display
"B", three times for "C", four times for "2".
The following screen will be displayed:
Open the high and low pressure taps on the machine and press the START to begin the refrigerant recovery/recycling phase. During this phase, the
graphic display will show the quantity of refrigerant recovered. The machine checks whether or not there is air in the bottle and, if necessary, purges
the non-condensable gas. The alarm will sound continuously and an AIR PURGE warning will be displayed. 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. 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 6-14 minutes. If any
residual refrigerant in the A/C system should increase in pressure during this phase, the machine will automatically begin recovering the refrigerant.

VACUUM

Use the quick-connect couplings to connect the hoses to the A/C system, bearing in mind that BLUE must be connected to the low pressure side
and RED to high pressure. If the system is equipped with a single quick-connect coupling for high or low pressure, connect only the relative hose.

VACUUM LEAK CHECKING

The machine will automatically perform a 2 minute AUTOMATIC LEAK CHECK when the time value is 11 minutes or longer. The AUTOMATIC LEAK
CHECK will start after 9 minutes of vacuuming. If a leak is detected the machine will notify the operator that a leak was detected and it will
not continue vacuuming. If no leak is detected, the machine will continue vacuuming for the time remaining. (Detection of micro leaks are not
guaranteed.)
