The AC800 will recover and recycle refrigerant from the A/C System, and then automatically
cycle off when a vacuum is sensed. This vacuum level can be seen on the Low Side Gauge.

A small quantity of Liquid refrigerant will probably still remain in the A/C System. This can
be detected by observing an increasing pressure reading on the Low Side Gauge.
As pressure rises to a preset level, the AC800 will automatically cycle on to continue recovering
refrigerant. Allow this automatic On/Off sequence to repeat until the vacuum level remains
constant for at least 2 minutes.
Note: Press and hold the top of the rocker switch marked RECOVER OVERRIDE to
remove any residual pressure that the AC800 may not remove when used on cooler
days.

INTERNAL CYLINDER FULL LIGHT:
This Light will illuminate if the Internal Charging Cylinders Fill to capacity, approximately 9 lbs.

Page 12. An optional 30 lb DOT Refillable Cylinder equipped with an Over Fill Protection device
can be used to store the refrigerant to be charged if the recovery process is not complete. Contact
your distributor, or call Technical Support at 800-468-2321 for details.
