Operation
(
Continued)
Vacuuming Dry Material
1. The filters must always be in correct
position to reduce the risk of leaks
and possible damage to Vac.
2. Your Vac comes with two VF3800
Filters installed. When using your Vac
to pick up very fine dust, it may be
necessary for you to empty the drum
and clean the filters periodically or
replace the filters to maintain peak
Vac performance.
NOTE:
A dry filter is necessary to pick up
dry material. If you use your Vac to pick
up dust when the filter is wet, the filter will
clog quickly and be very difficult to clean.
Optional Dust Collection Bags
Note:
This Vacs computer programing
only monitors for blockages in the pleated
filters. Use of the optional Dust Collection
Bag will keep the Smart-Pulse function
from sensing any blockages that occur,
leading to a premature drop in vacuum
performance.
1. The available Dust Collection Bag for
this Vac is catalog number VF3502.
2. The Dust Collection Bag is intended
for cleaning up dry debris ONLY.
3. If the debris being picked up has any
moisture, the bag will absorb the
moisture and may deteriorate very
quickly, making the bag nonfunctional.
4. If you are using your vacuum to pick
up fine dust, the Dust Collection Bag
will make cleanup easier.
Note:
Dust Collection Bag MUST be
used in conjunction with a Pleated
Cartridge Filters. Do not overfill the filter
collection bags. The overfilling of these
bags may cause the weight of the
collected debris to tear these bags and/or
make it difficult to remove the bag from
the vacuum’s drum due to its physical
size.
5. Directions for Installation and
Removal of Dust Collection Bags are
printed on the bags.
Vacuuming Liquids
1. Before using your vacuum for wet
pickup, ensure the drum is empty and
free of dust or debris.
2. Remove the filters. With the filter
removed, the float mechanism
activates to prevent water from
entering the motor blower housing.
If the filters are not removed, water
could enter the motor blower housing
which could overload and damage
the motor.
3. When the liquid in the drum reaches
a predetermined level, the float
mechanisms will rise automatically to
cut off air-flow. When this happens,
turn off the Vac, unplug the power
cord, and empty the drum. You will
know that the float has risen because
the Vac airflow ceases and the motor
noise will become higher in pitch,
due to increased motor speed.
IMPORTANT:
To reduce the risk of
damage to the Vac, do not run motor with
floats in raised position.
4. After using the Vac to pick up liquids,
the drum must be cleaned out,
and completely dried before use.
The filters must be re-installed before
using your machine to pick up dry
materials.
