PROCEDURE FOR REMOVING CONTAMINATED FILTERS AND FOR CLEANING
OF CONTAMINATED TANK
For the benefit of your health, you should always wear a face mask approved for use with asbestos any time
you are using or cleaning this vacuum cleaner. You should also wear gloves.
1. Unplug machine from power source.
2. Carefully and slowly remove lid only (be sure you have not accidentally lifted the cloth filter bag
at the same time). Set the lid/filter assembly aside.
3. Gently tap the inside of the cloth bag to loosen any particles that may be on the opposite surface. Do
this all around the inside surface of the bag.
4. Gently remove the cloth bag and set aside.
5. Carefully undo the elastic band from around the tank, remove “filter protector” from tank and place
into plastic bag marked “hazardous materials.”
6. Using a wiping cloth, dampened with water (not soaking wet), wipe down all of the exposed surfaces
inside to the tank; put the cloth aside - do not discard.
7. Carefully and “very” slowly, push the paper bag down and off of the intake tube, using the
attached cardboard collar. After the collar is removed from the intake tube, take the damp
cloth and wipe off any surfaces that were not previously wiped; at this time, rewipe the entire inside
of the tank and drop the wiping cloth into the plastic bag.
8. CAUTION: Hazardous materials must be disposed of properly. Never throw contaminated debris in
your usual trash receptacle. Place debris in a plastic bag or can marked “HAZARDOUS MATERIALS”
and take to a hazardous waste handler.
9. For proper assembly of new filters, see “Tank/Filter Set-Up Procedure.
CHANGING THE PREFILTER
The prefilter should be changed, using all of the precautions previously mentioned.
The prefilter should be changed when any of the following takes place:
1. Anytime there is an indication of a filter tear during normal operation of the unit. This tear
could be in any of the filters used.
a. paper dust containment bag
b. paper bag protector
c. cloth filter bag
These tears would show up during the tank clean-out procedure, or....
2. Every other tank clean-out period.
To change the prefilter, do the following before you do Step #3 of the normal clean-out procedure.
a. Wipe down all of the exposed surfaces on the underside of the removed lid, using the
dampened wiping cloth (see Step #6).
b. Remove the prefilter from the high efficiency filter. Be careful so as not to damage or puncture the
paper media used in the final filter. Do not attempt to clean the prefilter in any way; dispose
of by placing it into the tank you are now in the process of cleaning. DO NOT USE ANY TOOLS TO
REMOVE THE PREFILTER.
d. Before proceeding any further in cleaning the tank, first place a new prefilter (one only) onto the
H.E.P.A. / U.L.P.A filter.
