OPERATION AND FILTER CARE INSTRUCTIONS
The Minuteman Critical Filter Vacuum has been specifically designed to clean up hazardous dust of all types.
Special filters reduce the incidence of airborne dust that would be created by any other method of cleaning.
During the removal of hazardous dust, do not sweep, scoop, shovel, or in any manner handle other than by
vacuuming.
Do not at any time attempt to bypass, remove, substitute or by any other means change the filters used in
this vacuum.
Use only approved Minuteman Critical Filter Vacuum filters and filter bags.
Before attempting to use and before cleaning, be certain that you fully understand the instructions given
for the setting up or cleaning/changing of filters of this vacuum.
Each facility has its own individual and unique cleaning problems, it is suggested that you use the following:
1. Fully open the plastic bag and place it down into the tank; #6 on the underside of the intake tube as shown.
2. Take the paper bag that has the cardboard collar attached and open it up by gently pulling the folds apart.
3. You will notice two creases on the top side of the collar; carefully bend the ends down (toward) the bag.
4. Insert this bag into the tank and push it to the bottom, taking care not to snag the plastic bag.
5. Locate the cardboard collar around the intake tube and gently work it up past the raised ring that runs around
the tube.
6. Push the plastic bag down past the paper bag; position it about 1/2 to 2/3 down past the top of the bag.
7. Starting at the bottom of the cloth filter, slip the paper filter protector over the entire cloth filter until the elastic
band on the paper filter protector goes around the black plastic frame of the cloth filter.
8. Ensure that the inside steel frame that supports the cloth filter is inserted into the tank with the cut out section
facing the front of the down tube. Then insert the cloth filter and paper filter protector inside the tank. Be careful
not to rip the paper filter protector when pushing the cloth filter with steel frame into the tank.
9. Position the lid onto the tank, making sure that the paper filter elastic is inside the cloth filter frame so that the
H.E.P.A. or U.L.P.A. filter will go down inside the cloth filter. Make sure that the motor lid is seated onto the ring
of the cloth filter frame completely around the tank.
10. Snap the lid latches into place.
For proper cleaning of the tank and removal/changing of the filters, see "Procedures in Removing Contaminated
Filters and Cleaning of Contaminated Tank."
PROCEDURES IN REMOVING CONTAMINATED FILTERS AND CLEANING OF CONTAMINATED TANK
Always wear a facemask and gloves when conducting this procedure.
1. Unplug the machine from the power source.
2. Carefully and slowly unlatch the tank latches and remove the vacuum lid only (be sure when you lift up on the
lid that the cloth filter stays inside the tank.) Set the lid with either a H.E.P.A. or U.L.P.A. filter assembly aside.
3. Gently remove the cloth and paper filter protector from the tank. Carefully place the paper and cloth filter into a
plastic bag. With one hand grab the bottom of the paper filter protector through the plastic bag and with the
other hand release the elastic band from around the cloth filter frame. Slide the cloth filter out of the paper bag.
Set the cloth filter and frame aside.
4. Before closing up the plastic bag with the used paper filter inside, check the impact filter attached to the
H.E.P.A. or U.L.P.A. filter for any noticeable dirt. The impact filter should be changed every other time you
change the paper filter or if any dirt particles are noticed during inspection. Then the used impact filter can also
be put into the plastic bag before sealing up for disposal. See "Changing the Pink Impaction Filter", on
page 5, for more information.
5. Carefully surround the paper debris bag with the plastic bag in the bottom of the tank. Pull the opening of the
plastic bag securely around the down tube with one hand. This plastic bag will completely encapsulate the
debris bag. Push downward on the debris bag on the debris bag's cardboard collar until it slips off of the
downtube.
6. Slowly pull the top of the plastic bag upwards. When you have the plastic bag fully extended upwards, slowly
squeeze the plastic bag closed to avoid trapping excess air. Twist the plastic bag until enough plastic can be
tied into a knot.
7. Lift the bag out of the tank and dispose of it properly.
