WET VACUUMING

Your 3931A can also be used for wet
vacuuming.
Do not use to vacuum
! WARNING
flammable liquids, gases,
or explosive dusts, like gasoline or other
fuels, lighter fluid, varnish, polyurethane
coatings, cleaners, oil-based paints,
natural gas, hydrogen, coal dust,
magnesium dust, grain dust, or gun
powder. Electric motors create sparks, which
may ignite the dust or fumes.
1. Before wet vacuuming, run the vacuum in
the PULSE-CLEAN™ mode.
2. Empty the canister to prevent encrustation
when wet vacuuming. If bag is in canister,
remove it as well.
Notes:
• Empty the canister before wet vacuuming.
• Do not use a VAC013 dust bag when wet
vacuuming. If a bag is to be used when
vacuuming wet material, a VAC022 heavy-
duty bag must be used.
• Wet/dry dust: If VAC013 bag is in the
canister, remove it as well. (VAC022 bag
can remain in canister.)
• The filter cartridge must be used when wet
vacuuming.
• Do not activate the PULSE-CLEAN™
mode when the contents of the vacuum
cleaner are wet.
• The unit is equipped with water level
sensors. The unit switches off when the
maximum filling height is reached. The unit
still has power, but will not operate. The
unit must be first switched off before it can
be switched on again.
• When the unit is shut off, some water may
flow out of the hose.
• To prevent siphoning or spillage, lift the
suction hose out of the liquid before
draining the vacuum cleaner.
• Before opening and emptying, move the
switch to the OFF position.
• Before opening and emptying, always
disconnect the vacuum cord from the
power supply.
• In order to avoid mildew, after wet
vacuuming, remove the VAC022 bag (if

one is installed) and remove both filter
cartridges and allow them to dry
thoroughly. Dry the filter and canister
thoroughly so that dust cannot adhere to
moist parts. Also remove the control unit
and allow it to dry, too.
• Use a dry filter for subsequent dry
vacuuming. We suggest purchasing extra
filter cartridges when frequently alternating
between wet and dry vacuuming and swap
them out as appropriate.
Clean the canister and accessories with
water. Wipe the top section with a moist
cloth.

See Figure 6.
1. Unlock the canister latches and remove
the control unit.
2. Clean the water level sensors with a soft
cloth.
3. Reattach the control unit again
