Procedures for exchanging filters
· All used filters, bags, and debris must be treated as
a hazardous substance and must be disposed of in accor-
dance with all federal, state, and local regulations.
· Pre-filter
Open the dust chamber lid by pressing the release button
and rotate the chamber lid open. Open the filter grid by
pulling back and rotating the grid upward. Remove the pre-
filter. Clean the sealing surfaces before reinstalling the new
pre-filter. Close the filter grid and press firmly to lock the
grid in place.
· HEPA filters
Note - This cleaner contains two HEPA filters, each located
on opposite sides of the lower housing assembly. Each is
replaced using the following procedure. Open the filter grid
by pressing the release tab, and rotate the filter grid open.
Use a flat screwdriver to remove the screw attaching the
top of the HEPA filter frame to the lower housing. Using
care to not dislodge any debris, remove the HEPA filter by
pulling on its top and rotating out until its bottom tabs dis-
engage from the lower housing. Clean the sealing surfaces
before reinstalling the new HEPA filter.
When installing the new HEPA filter, always push on the
plastic frame of the filter, NEVER on the pleated filter
media. Damage will result to the filter and it will be inef-
fective in filtering out hazardous substances. Install the
HEPA filter into the cleaner with the "HEPA" label facing
outward. Making certain that the two tabs of the HEPA
filter frame are correctly secured into the slots in the lower
housing, press the filter forward and reinstall the mounting
screw. Make certain the filter is properly seated at the
sealing surface. Reinstall the filter grid and press firmly to
lock the grid in place. Repeat procedure for the second
HEPA filter.
