DRAIN RECOVERED OIL

Oil is separated from the recovered refrigerant and MUST be removed following EACH Recover/Recycle procedure to determine the amount (if any) necessary to add into the A/C System as follows:

Note: The AC880 must be connected to power source. Drain Recovered Oil may be done while the AC880 Vacuum Pump is ON.

1.Press and hold the Oil Drain Re-pressurization Switch (16) for 5 seconds and then release it.

2.Slowly open the Oil Drain Valve (17) to drain any oil which may have been removed from the A/C System.

Unless the A/C System had previously been overfilled, the AC880 will typically not remove enough oil to make replenishment necessary.

3.Close the Oil Drain Valve (17).

4.Press and hold the Oil Drain Re-pressurization Switch (16) for 5 seconds. This permits any residual Non-Condensable Gas to be re-circulated for reprocessing during the next recycle procedure.
