FILTER OPTIONS AND SUGGESTIONS
CHIMNEY CLEANING AND FINE DUST PICK-UP:
When using the vacuum for chimneys it is recommended that all filters be in
place to prevent premature loss of suction and to extend the life of the HEPA
filter. The poly bags can be eliminated when the paper collection bag is being
used. However, using the poly bag will make collection bag changes and
disposal a cleaner, less messy procedure.
DRYER VENT, LINT AND LARGE PARTICLE PICK-UP:
When using the vacuum for dryer vents, the paper collection bag may be
eliminated, allowing materials to load directly into the 4-mil poly bag. ALL OTHER
FILTERS MUST BE IN PLACE. If you choose to eliminate the paper collection
bag, you can remove the lower section of the down tube (the rubber reducer and
metal tube). This will prevent any clogging that could be caused by lint and larger
objects.
FILTER MAINTENANCE AND REPLACEMENT INSTRUCTIONS
Warning: When a loss of vacuum power is detected, the vacuum should be turned off immediately. Continued use
of the machine could result in severe damage to the motor and/or HEPA filter. This loss of vacuum power could be
caused by one of the following:
A. The paper collection bag may be full and needs to be replaced.
B. The tank may be full and needs to be emptied.
C. The wand, hose, or down tube may be clogged and needs to be cleared.
D. The impaction prefilter may be clogged and needs to be replaced. (Never try to clean the
impaction prefilter, it should be discarded.) See section on changing the impaction prefilter.
E. The Filter bag with ring may be clogged and needs to be cleaned or replaced.
F. The HEPA filter may be clogged and needs to be replaced.
To prolong the life of the HEPA filter and motor, the paper collection bag should be changed when it is 1/2 full. The
impaction prefilter should be changed at least every other time that the collection bag is changed
