VACUUMING DRY MATERIALS

The Filter must always be in correct position at all times to avoid leaks and possible damage to Vac.
When using your Vac to pick up very fine dust, it will be necessary for you to empty the Drum and clean the Filter at more frequent intervals to maintain peak Vac performance.

NOTE: A dry Filter is necessary to pick up dry material. If you use your Vac to pick up dust when the Filter is wet, the Filter will clog quickly and be very difficult to clean.

VACUUMING LIQUIDS

Vacuuming up small amounts of liquid (less than 2″ (5 cm) collected in Dust Drum) does not require Filter removal.
When larger amounts of liquid are to be picked up, remove all Dry Use Only Paper Filter(s) and replace with a RIDGID VF3700 Wet Application Foam Filter. Do Not remove the Filter Cage or Float. The Foam Filter is specifically designed for high volume liquid pick up. If the Paper Filter is used and becomes saturated, you may see “mist” coming from the Blowing Port.
When the Drum is “full” the Float will rise and cut off airflow. The motor sound will rise in pitch and its speed will increase indicating the Drum is “full”. Turn OFF the Vac before emptying the Drum.
Following use of Vac for wet pick up, allow Filter to dry completely to avoid mildew and Filter damage.

IMPORTANT: To reduce the risk of damage to the Vac, do not run Motor with Float in raised position.

⚠ WARNING:
Do not operate without filter cage and float, as they prevent liquid from entering the impeller and damaging the motor.
