Vacuuming Liquids; Filter Performance Sensor; Emptying The Drum - RIDGID WD1950 Operator's Manual

3. If your filter is wet but you need to use
the vac to pick up dry material, you can
quickly dry the filter by running the vac
without hose attached for about
10 minutes. The clean air rushing
through the vac will help dry the filter.

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 we recommend 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. When this happens, turn off
the vac, unplug the power cord, and
empty the drum. You will know that the
float has risen because vac airflow
ceases and the motor noise will become
higher in pitch, due to increased motor
speed.
4. After using the vac to pick up liquids, the
filter must be dried to reduce the risk of
possible mildew and damage to the filter.
IMPORTANT: To reduce the risk of
damage to the vac do not run motor with
float in raised position.

Filter Performance Sensor

1. This Wet/Dry Vac features an innovative
device for determining when your filter
needs to be cleaned. This patent
pending design works whether the
Wet/Dry Vac is on or off.
2. Bars of color show the cleanliness of
your filter. All green bars indicate that
your filter is clean and ready to use.
3. As the filter becomes dirty, orange bars
will appear and green bars will
disappear.
4. All orange bars indicate that your filter is
dirty and needs to be cleaned or
replaced.
5. Your Wet/Dry Vac operates most
efficiently and powerfully, with a clean
filter. When the filter performance
sensor shows all orange bars, the
8/15/07 1:32 PM
performance of your Wet/Dry Vac is
approximately 40-55% of its original
power with a clean filter. At any point
during the increasing orange bars,
you may elect to clean the filter.
6. To set the indicator bars back to the
original full green position, press the
sensor reset button.
NOTE: Do not press the sensor reset button
while the Wet/Dry Vac is running. This may
damage the filter performance sensor.
7. Press the sensor reset button until all
green bars show. This should be done
whenever you clean or replace the filter.
Depending on how clean you get the
filter, will determine how many orange
bars show. A new filter will show all
green.
