Operation (Continued)
Vacuuming Dry Materials
1. The filter must always be in correct
position at all times to avoid leaks and
possible damage to Vac.
2. When using your Vac to pick up 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 material when the filter is wet, the filter
will clog quickly and be very difficult to
clean.
3. If your filter is wet but you need to use
the Vac to pick up dry material, you
must first allow the filter to dry.
Vacuuming Liquids
1. When picking up small amounts of
liquid the filter may be left in place.
2. When picking up large amounts of
liquid it is recommended that the filter
be removed. If the filter is not removed,
it will become saturated and misting
may appear in the exhaust.
3. When the liquid in the drum reaches a
predetermined level, the float
mechanism will rise automatically to cut
off air-flow. You will know that the float
has risen because suction stops and the
motor noise will become higher in pitch,
due to increased motor speed.
When this happens, turn off the Vac,
unplug the power cord, and empty the
drum.
4. After using the Vac to pick up liquids,
the filter must be dried to avoid possible
mildew and damage to the filter.
WARNING: Do not operate
without filter cage and float, as they
prevent liquid from entering the
impeller and damaging the motor.
Emptying the Drum
1. Remove the lid. Pull the flexible latches
outward on each side of the lid to
release from the drum.
2. While holding the latches out, lift the
top assembly up and away from the
drum.
3. Lay top assembly upside down on a
clean area while emptying drum or
changing filter.
4. Dump the drum contents into the
proper waste disposal container.
Moving the Wet/Dry Vac
Should it become necessary to pick the
Vac up to move it, DO NOT pick the Vac
up by the lid handles unless dust drum is
empty. To avoid dropping the Vac, due to
latches releasing or possible part
breakage, pick the Vac up by the dust
drum.
