Express 1 Ton Van V8-5.7L VIN R (1999)
^
The recovery might remove a small amount of the A/C system lubricating oil polyalkylene glycol (PAG) with the refrigerant. Often, the
recovery does not remove any oil. The amount of oil removed varies greatly. The amount of oil removed depends on various conditions of the
vehicle. The J 39500-B separates the oil from the refrigerant.
^
The flashing of the OIL/OZ (OIL/GMS) indicator is a reminder: drain the recovered oil at this time. Replace the same amount of oil into the
A/C system when you recharge with refrigerant the system.
At the end of the initial recovery process, the display shows CPL.
The display then alternately displays the weight of the refrigerant recovered and the OIL/OZ (OIL/GMS) indicator.
25. Slowly open the oil drain valve in order to drain the oil into the calibrated oil catch bottle at the bottom of the unit.
26. Close the oil drain valve.
27. Record the amount of oil in the catch bottle.
28. Dispose of the recovered oil in an appropriate manner.
Never reuse this oil.
29. Observe the LOW-SIDE GAGE reading on the control panel.
^
If the A/C system maintains a vacuum, the recovery is complete.
^
A rise in the LOW-SIDE GAGE pressure above 0 indicates the presence of more refrigerant.
IMPORTANT:
^
If the display flashes the FULL indicator during the recovery process, the unit ceases operation. The unit tank is full.
^
Prior to continuation of the recovery process, install an empty unit tank (J 39500-50) in order to accommodate additional refrigerant. Do not
use any other kind of tank.
^
If necessary, lower the amount of refrigerant in the unit tank by charging other vehicles.
If refrigerant remains in the system, press the HOLD/CONT key on the keypad in order to recover the additional refrigerant.
30. Repeat the previous step, as necessary, until the system maintains a vacuum for 2 minutes.
