Maintaining AstroVac with Paper Bag
Replacing the Paper Bag
Sealed
paper bag units incorporate a two-layer disposable paper bag for superior
filtration. These paper bags are also inexpensive and easy to throw away
making vacuum maintenance easy. The mass of dirt and debris picked up by
your central vacuum system is deposited in the filter bag inside the dirt
canister. To remove this accumulation, follow these simple steps: Sealed
Paper Bag Systems
- Remove the lid by lifting straight up (figure 1d). There are no hinges
or clamps.
- Remove the bag by sliding the rubber gasket that surrounds the hole in
the paper bag off the plastic inlet stem that protrudes through the side of
the canister (figure 2d).
Once the bag is off of the inlet stem, seal
the bag by removing the backing from the tab and cover the hole with the
flap. Press the flap so that it securely seals over the hole (figure 3d).
This will help prevent dirt and dust from escaping.
Now, lift the paper
bag from the dirt canister and place in a suitable trash container.
- Take a new bag and extend it fully (figure 4d), place it in the
canister, and slide the rubber gasket onto the inlet stem until the rubber
gasket drops into place in the ridge that is around the inlet stem (figure
5d).
- Carefully replace the lid onto the dirt canister to ensure that it seals
properly or it could cause a vacuum leak and reduce the cleaning efficiency
of your system.
NOTE: This step is only required in the event that the bag breaks.
If bag breakage does occur, it is necessary to lift the plate located under
the bag and clean the small screen.

HOW OFTEN SHOULD I CHECK OR EMPTY THE PAPER BAG?
The filter bag should be changed or cleaned when there is 3-6 inches of dirt or
anytime there is a noticeable reduction of air flow at the cleaning tool.
Initially, the dirt canister should be checked or emptied weekly until some idea
can be obtained as to how long it takes to half fill the canister under your
normal cleaning routine. All vacuum systems will function more effectively if it
is emptied frequently. Under no circumstances should you allow your dirt
canister to become more than 3/4 full before emptying. (Note: The canister will
fill more rapidly if NEW carpets are being cleaned for there is usually a
tremendous quantity of loose fibers that are retained in the carpet from the
manufacturing process. In some instances it may take several months before all
of these loose fibers are removed.)
