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.
