WARNING
– ALWAyS DISCONNECT THE PLUG fROM

When using the reusable dry filter to pick up dust and
dry material, you must install foam sleeve and reusable
dry filter to ensure proper filtration. If the vacuum has
been used to pick up liquids, the foam sleeve must be
cleaned and dried before installing for dry pick up. With
tank cover in an upside down position, slide foam sleeve
down over lid cage pulling until foam sleeve completely
covers lid cage (figures 4, 5). Center the reusable dry
filter on lid cage (figure 6), slide mounting ring down over
filter until ring is positioned against the ribs of the lid cage
(figure 7). The reusable dry filter should always be in
position over the foam sleeve for dry pick up. To remove the filter for cleaning,
remove mounting ring and filter from lid cage (figure 8). To clean the reus-
able dry filter, shake off excess dirt and dust or (depending on the condition
of the filter) rinse with water. Allow the filter to dry completely and reinstall.

INSTALLING THE CARTRIDGE fILTER
(Not standard with all models)
NOTE: If foam sleeve is in postion over lid cage, it must be removed before installing cartridge
filter.
The cartridge filter can be used for wet or dry pick
up; installation is the same for both. When picking up
large quantities of liquid please refer to the Wet Pick up
Operation section in this manual. use the cartridge filter
in position over the lid cage for most general dry material
pick up. With the tank cover in an upside down position,
slide the cartridge filter down over the lid cage, pushing
until the filter seals against the cover (figure 9). Place
filter retainer into the top of the cartridge filter, hold the
tank cover with one hand, turn the handle on the filter
retainer clockwise to tighten, locking the filter into place
(figures 10 & 11). To remove the filter for cleaning, again
hold the tank cover and turn the filter retainer counter-
clockwise to loosen and remove, slide the cartridge filter
off the lid cage (figures 12 & 13). To clean the cartridge
filter shake or brush off excess dirt or rinse (from the
inside of the filter) with water, dry completely (approximately 24 hours) and reinstall (figures
14 & 15). NOTE: If the filter has been used for wet pick up, it must be cleaned and dried before
using for dry pick up.
INSTALLING THE DISPOSABLE fILTER BAG
(Not standard with all models)
1. use for dry pick up only. use in conjunction with cartridge
filter for picking up soot, cement, plaster or drywall dust.
2. With cord disconnected from receptacle, pull latches in an
outward motion and remove tank cover.
3. Grasp cardboard collar firmly and slide rubber guard onto
inlet fitting as far as possible (figure 16).

WET PICk UP OPERATION
Remove ALL dirt and debris found in the tank. The vacuum requires only a minimum of conver-
sion when going from dry to wet pick up. Remove all dry use filters from the vacuum. A clean
cartridge filter may be used for vacuuming small amounts of liquids. for proper installation of
the cartridge filter refer to Installing the Cartridge filter. for best results when vacuuming large
quantities of liquid, remove the cartridge filter. When vacuuming liquids containing debris, it is
recommended purchasing a foam sleeve and install over filter cage; otherwise a foam sleeve
is not required for wet pick up. foam sleeve and additional filters may be purchased by visiting
our website at www. shopvac.com, contacting our customer service department, or purchasing
at your local Shop-Vac ® distributor.
Misting in exhaust air may occur if the filter becomes saturated during wet pick up. If misting
occurs, remove filter and allow to dry or, replace with another dry filter to eliminate the misting
and possible dripping of liquid around the lid. Turn the unit off immediately upon completing a
wet pick-up job or when tank is full and ready to be emptied. Raise the hose to drain any excess
liquid into the tank. The interior of the tank should be periodically cleaned.
The foam sleeve should be cleaned periodically as described in the following steps:
1. Always disconnect the plug from the wall receptacle before removing the tank cover. Place
tank cover in an upside down position. Remove foam sleeve by sliding it up and off the lid
cage.
2. Shake excess dust off foam sleeve with a rapid up and down movement.
3. hold foam sleeve under running water for a minute or two, rinsing from the inside. A water
wash is not always required, depending on the condition of the foam sleeve.
4. Gently wring out excess water, blot foam sleeve with a clean towel, and allow to dry. The
foam sleeve is now ready to be reinstalled on the lid cage.

your vacuum can be used as a powerful blower. To use your unit as a blower,
clear hose of any obstruction. Insert machine hose end into blower port on
rear of unit (figure 18). Twist slightly to tighten the connection. Caution
should be used when using as a blower due to the powerful force of air when
using certain attachments.

Without Tank Drain
Liquid waste may be emptied by removing the tank cover. To empty, stop the motor and
remove the plug from the wall receptacle. Remove the tank cover and deposit the liquid waste
contents in a suitable drain. After tank is empty, return the cover to its original position. To
continue use, plug the cord into the wall receptacle and turn the unit on.
With Tank Drain
Liquid waste may be emptied by removing the tank drain. To empty, turn unit off and remove
plug from wall receptacle. Remove the drain cap and deposit the liquid waste contents in a
suitable drain. After the tank is empty, return the drain cap to its original position. To continue
use, plug the cord into the wall receptacle and turn the unit on.

AUTOMATIC SUCTION SHUT-Off

The vacuum is equipped with an automatic suction shut-off that operates when picking up
liquids. As the level of the liquid rises in the tank, an internal float rises until it seats itself
against a seal at the intake of the motor, shutting off suction. When this happens, the motor will
develop a higher than normal pitch noise and the suction is drastically reduced. If this occurs,
turn unit off immediately. failure to turn unit off after float rises and shuts off suction will result
in extensive damage to the motor. To continue use, empty the liquid waste from the tank as
outlined in the previous paragraph.
