OPERATING AND FILTER CARE INSTRUCTIONS
The Minuteman Model X-1000 Critical Filter Vacuum has been designed to clean up hazardous and toxic dust of all
types. A special High Efficiency Particulate Air (H.E.P.A.) filter and a series of “prefilters” used with this vacuum reduce
the incidence of airborne dust that would be created by any other method of cleaning.
During the removal of hazardous toxic dust, do not sweep, scoop, shovel, or in any manner handle other than vacuum-
ing.
Do not at any time attempt to bypass, remove, substitute, or by any other means change the filters recommended for
use with this vacuum. Use only approved Minuteman filters and filter bags.
Do not at any time, or in any way, attempt to clean or remove dust particles that may collect or accumulate on the
surface of the H.E.P.A. filter media.
Do not reverse or attempt to clean “prefilters” which have accumulated dust, for the purpose of reusing them.
Since each facility has its own individual and unique cleaning problems, it is suggested that you use the following
guidelines in determining the length of time between filter changes and/or tank emptying:
1. Empty tank after accumulating about 20 pounds of debris.
2. Replace all prefilters each time you empty tank or replace collector bag. In “white room” applications where the
primary objective is to contain non-toxic dust, the “impact” prefilter should be visually checked to determine re-
placement need. Impact prefilter should be changed when they show dust accumulation.
The efficiency of your vacuum will be determined by the amount and the density of the material you are vacuuming. All
vacuums will lose efficiency as they become filled. The operator must, therefore, be the one to determine the frequency
for emptying and changing filters based on the efficiency and performance of the vacuum during the cleaning process.
The Model X-1000-15 vacuum lid assembly is equipped with a motor cooling air recirculating tube to prevent carbon dust
particles, generated within the motor assembly, from being exhausted out of the machine. The recirculating tube directs
the motor cooling air into the vacuum tank and through the prefilter and H.E.P.A. filter before it is exhausted into the
atmosphere. The recirculating tube requires a small amount of vacuum air flow to operate effectively which may result
in a slightly reduced vacuum performance. If you are not operating under “clean room” conditions that would require the
use of this device, you may disconnect it by simply removing the curved tube on the vacuum lid assembly and plugging
the hole/tube in the lid. Do not plug the hole/tube that is in the side of the dome.
TANK/FILTER SET-UP PROCEDURE FOR MODEL X-1000-15
1. Remove vacuum lid assembly from tank.
2. Install impaction prefilter No. 9, Page 5.
3. Place cloth filter bag onto and into tank using formed rubber gasket as a guide and press down firmly onto the tank
rim.
4. Position vacuum lid onto the tank, making sure that gasket of the lid is seated onto the rubber ring of the cloth bag
frame completely around tank.
5. Snap lid latches into place.
OPTION:
A. A disposable “filter bag protector”, No. 5, Page 17, can be used in the tank, installed ahead of the cloth filter bag.
The filter bag protector is inserted into the tank with the elastic band snapped around the rim of the tank. (About 2
inches of the bag should be outside the tank, then proceed with step 3 above.)
B. Intake down tube, see No. 14, Page 9, with disposable collector bag. If your tank assembly has this option, install
disposable bag by locating the cardboard collar around the intake tube and gently work it up past the raised ring
that runs around the tube, then proceed with step 3 above.
