GROUNDING INSTRUCTIONS
This appliance must be grounded. If it should malfunction or breakdown, ground-
ing provides a path of least resistance for electric current to reduce the risk of
electric shock. This appliance is equipped with a cord having equipment ground-
ing conductor and grounding plug. The plug must be inserted into an appropriate
outlet that is properly installed and grounded in accordance with all local codes
and ordinances.
This appliance is for use on a nominal 120/240 Volt circuit, and has a grounded
plug that looks like the plug illustrated in sketch A below. A temporary adapter that
looks like the adapter illustrated in sketches B and C may be used to connect this
plug to a 2-pole receptacle as shown in sketch B if a properly grounded recep-
tacle is not available. The temporary adapter should be used only until a properly
groundedoutlet(sketchA)canbeinstalledbyaqualiedelectrician.Thegreen
colored ear, lug, or the like extending from the adapter must be connected to a
permanent ground such as a properly grounded outlet box cover.
Whenever the adapter is used, it must be held in place by a metal screw.
NOTE: In Canada, the use of a temporary adapter is not permitted by the Canadian
Electrical Code.

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 oat rises until it seats itself against a seal at the
intake of the motor, shutting off suction (Figure 9). When this happens,
the motor will develop a higher than normal pitch noise and the suction
is drastically reduced. If this occurs, turn the unit off immediately.
EMPTYING LIQUID FROM THE TANK
1. Remove liquid from the tank by using the DRAIN HOSE.
2. Detach the DRAIN HOSE from the clip on the outside of the tank. (See Figure
10)
3. Remove the stopper plug on top of the DRAIN HOSE (See Figure 11).
4. PlacetheDRAINHOSEnexttotheoordrainandlettheliquidemptyfrom
the tank.
5. Once the tank is empty, reattach the stopper plug and clip the DRAIN HOSE
to the side of the tank.

MAINTENANCE
1. Tank Cleaning – DRY USE
After working or when the cloth dust bag is full, it is recommended to clean
the tank to remove any dust or debris. This dust or debris could decrease the
suction considerably. Prior to cleaning the tank, disconnect the power from
the motor.
• Release the Tank Clips securing the motor assembly and remove the motor.
• Remove the HEPA Filter and blow off
• Remove the Cloth Filter and blow off
• Remove the Cloth Dust Bag and replace with
a new one
2. HEPA Filter Cleaning
• The HEPA Filter can be washed by using
clean, warm water.
• The HEPA Filter can also be cleaned by blow-
ing with compressed air.
• Allow the HEPA Filter to fully dry before using.
3. Tank Cleaning - WET USE
• After soaking up dirty water it is recommended that you should clean the
tank after use.
• Release the Tank Clips securing the motor assembly and remove the motor.
• Move the Tilt/Lock Knobs to the lower position to enable the tank to tilt back
and spray (Figure 13)
• Spray inside of the tank with a water hose to remove any debris (Figure 14).
When the Tilt/Lock Knobs
are in the “UP” position,
they tighten against the
Tilt/Dump Support Shelf
to secure the Stainless
Steel Tank.
Putting the Tilt/Lock Knobs in the “DOWN”
position allows the Stainless Steel Tank to
tip backwards on the Tilt/Dump Support
Shelf for easier cleaning.
NOTE: Make sure that the motor is
removed prior to tipping the tank
backwards.
