<CHARGING XX:XX lb>
NOTE: When working with A/C systems with a single high-pressure (RED) coupling, set the charging quantity 3 oz. (.19 lb or 85g) more than the
required quantity, since in this case it will be impossible to recover the residual refrigerant from the hoses after charging.
NOTE: In most cases, the quantity of refrigerant being charged into the A/C system is given on a data plate inside the engine compartment of the
vehicle. If you do not know the correct quantity, consult the relevant manuals.
2. This model is equipped with refrigerant capacities stored in its database. Press the
↓ key, the following will appear on the display:
<ALFA ROMEO>
AUDI
BMW
CHRYSLER/JEEP
Use the arrow keys ( ↓↑) to select the required vehicle brand and press ENTER to confirm. The display will now show the various models (for
example, if the brand chosen was FORD):
<COUGAR>
ESCORT
ESCORT D
FIESTA
Use the arrow keys ( ↓↑) to select the model required and press ENTER to confirm. The following will appear on the display:
VACUUM 20 MIN
<FILLING w:yz lb>
where “w,yz” refers to the amount of refrigerant for the vehicle selected. The machine will be ready to enter the correct quantity of refrigerant.
Confirm by pressing the ENTER key.
Open the high and low service valves on the machine and press the START key to begin the refrigerant recovery/recycling phase, which will be
indicated on the LCD as “Recovery/Recycling”. During this phase, the LCD will display the quantity of refrigerant recovered. Upon completion of
recovery, the machine will stop and automatically discharge the used oil extracted from the A/C system during the recovery phase. The oil discharge
operation lasts 4 to 12 minutes depending on the ambient temperature. The words “Recovery/Recycle” will flash while the oil is being discharged.
If any residual refrigerant is left in the A/C system, as indicated by an increase in pressure during the oil discharge phase, recovery will automatically
restart.
NOTE: Stopping the recovery phase before the oil is discharged may damage the recovery/recycle machine’s compressor.
Upon completion of discharge, the machine will check for the presence of air in the tank, and if it’s necessary, purge the non condensable gases.
The alarm will sound continuously and the display will show:
AIR PURGE
Recovery ref x:xx lb
Tp: xx psi T:xx ˚F
The Recovery/Recycle machine will automatically purge non-condensable gases (NCGS) if excess NCGS are detected at the end of recovery. Allow
the unit to complete this procedure, eliminating the chance of NCGS being charged to the AC system.
The machine will automatically go on to running the vacuum phase for the preset time. Upon completion of the vacuum phase, the machine will
stop, emit a beep, and display:
