INSPECTION

Carefully unpack and inspect your machine for shipping damage. Each unit is tested and
thoroughly inspected before shipment, and any damage is the responsibility of the delivery
carrier who should be notified immediately.

ELECTRICAL - 115 Volt

This machine is designed to operate on a standard 15 amp. 115 volt, 60 hz, AC circuit.
Voltages below 105 volts AC or above 125 volts AC could cause serious damage to the motor.

WARNING

Electric motors can cause explosions when operated near explosive materials or vapors.
Do not operate this machine near flammable materials such as solvents, thinners, fuels,
grain dust, etc.

GROUNDING INSTRUCTIONS

This appliance must be grounded. If it should malfunction or breakdown, grounding provides a
path of least resistance for electric current to reduce the risk of electric shock. This appliance
is equipped with a cord having an equipment-grounding conductor and grounding plug. The
plug must be plugged into an appropriate outlet that is properly installed and grounded in
accordance with all local codes and ordinances.

DANGER - Improper connection of the equipment-grounding conductor can result in a

risk of electric shock. Check with a qualified electrician or service person if you are in doubt as
to whether the outlet is properly grounded. Do not modify the plug provided with the appliance
— if it will not fit the outlet, have a proper outlet installed by a qualified electrician.

This appliance is for use on a nominal 120-volt circuit and has a grounding plug that looks like
the plug illustrated in sketch A below. Make sure that the appliance is connected to an outlet
having the same configuration as the plug. No adapter should be used with this appliance.

2

USER MAINTENANCE INSTRUCTIONS

All service and repair should be performed by a qualified vacuum service representative
or electrician. No user serviceable components are employed in the electrical vacuum
lid head assembly. No lubrication of the motor is required.

CLOTH BAG & HOSE ASSY

Cloth bag and hose assy. are user maintenance items and can be replaced when worn out.
Cloth bags can be maintained by blowing dust off of the bag and then laundered. Cloth bags
should be completely dryed before re-installing into machine. For optimum performance,
empty and clean filter bag regularly. A clogged and dirty bag restricts the flow of air and
results in reduced vacuum. The Hose Assy. can be maintained by wiping off with a dampened
cloth of mild liquid soap and water, then allowed to dry.

CORD STORAGE

While not in use storage can be accomplished by winding cord around motor lid assy.
Cord should be completely unwound from Lid Assy. during operation.

• Do not use with damaged cord or plug. If appliance is not working as it should, has
been dropped, damaged, left outdoors, or dropped into water, return to service center.

• Do not pull or carry by cord, use cord as handle, close a door on cord, or pull cord
around sharp edges or corners. Do not run appliance over cord. Keep cord away
from heated surfaces.

• Do not unplug by pulling cord. To unplug, grasp the plug, not the cord.

• Do not handle plug or appliance with wet hands.

• Always unplug the machine when removing the head off the tank. This equipment
should be stored indoors and not exposed to rain.

OPERA TION AND FIL TER CARE INSTRUCTIONS

The Minuteman Critical Filter V acuum 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 V acuum 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:

T ANK/FILTER SET-UP PROCEDURE

Refer to Page 6

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 att ached 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 CONT AMINA TED FILTERS AND CLEANING OF CONT AMINATED T ANK

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. T wist 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 .

(Cont’d) PROCEDURES IN REMOVING CONTAMINA TED FIL TERS AND CLEANING OF CONT AMINA TED T ANK

8. Before inserting another plastic bag and paper debris bag, take a wet paper towel and wipe out the inside of the
tank of any dirt contaminate. Put this inside the plastic bag along with the used paper filter protector and
impact filter . This plastic bag should also be twisted shut, tied into a knot and disposed of properly.

9. T o help prolong the life of the H.E.P.A. or U.L.P .A. filter , a spare cloth filter should be interchanged with the
existing cloth filter . V acuum out when there is any noticeable dirt or soil. The cloth bag can also be sprayed
with a garden hose from the inside out to remove any soil. Make sure that the cloth filter is completely dry
before reinstalling it into the vacuum.

10. CAUTION: Any hazardous materials must be disposed of properly . Never throw contaminated debris into you
usual trash receptacle. Place debris in a plastic bag or can marked “Hazardous Materials” and take to a
hazardous waste handler.
