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,
slowlysqueeze 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.
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. To help prolong the life of the U.L.P.A. filter, a spare cloth filter should be interchanged with the existing cloth
filter. Vacuum 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.
11. For proper assembly of new filters, see “Tank Filter Set Up Procedures.”
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.
b. Remove the prefilter from the high efficiency filter. Be careful so as not to damage or puncture the U.L.P.A.
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.
c. Before proceeding any further in cleaning the tank, first place a new prefilter (one only) onto the U.L.P.A.
filter.
