WET VACUUMING

Do not use to vacuum 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.

Two VAC012 filter cartridges must be installed for wet vacuuming.

Before wet vacuuming, run the vacuum in the PULSE-CLEAN mode.

Before wet vacuuming, empty the canister to prevent encrustation of the canister.

Do not use a paper (VAC013) or plastic bag (VAC023) when wet vacuuming. If a bag is to be used when vacuuming wet materials, a heavy-duty bag (VAC022) must be used.

!WARNING To reduce the risk of electric shock, use only

VAC012 filters when wet vacuuming. Failure to use the VAC012 filters may allow water to reach electrical components.

•The VAC019 HEPA filters should not be used when wet vacuum because they will be damaged.

•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 switched off and empted 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 VAC012 filter cartridges and allow them to dry thoroughly. Dry the filter canister and control unit thoroughly so that dust cannot adhere to moist parts.

•Use a dry VAC012 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.

WATER-LEVEL SENSOR MAINTENANCE Clean the water level sensors occasionally:

See Figure 7.

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

4.Lock the canister latches.
