3. Maintenance Familiarize yourself with these home maintenance tasks as proper use and care of your cleaner will ensure continued cleaning effectiveness. 3-1 E A B D C Dirt cup The dirt cup assembly consists of the following parts: Lid (A) Dirt Cup (B) Pre-filter (C) HEPA Cartridge Filter (D) Dirt Inlet Opening (E) While the cleaner is in operation, the prefilter screen will stop larger debris from entering the HEPA cartridge filter chamber. This larger debris will be seen collecting in the left side of the dirt cup. The HEPA cartridge filter will collect fine particles that have passed through the pre-filter screen. When to empty It is recommended that the dirt cup be emptied before the dirt reaches the dirt inlet opening on back of dirt cup (Fig. 3-1) or after every use if preferred. CAUTION: Very fine materials, such as face powder or cornstarch, may seal the filter and cause loss of suction. When using the cleaner for this type of dust, empty the cup and clean the filters often. 3-2 F How to empty Disconnect cleaner from electrical outlet. Do not use cleaner without dirt cup or filters in place. Push latch (F) to the left to unlock. Lift cup slightly and pull straight out to remove from cleaner. 3-3 Remove lid. Note: It is not necessary to remove the HEPA cartridge filter to empty the dirt cup. Tap side of cup until no more dust particles fall from the HEPA cartridge filter. 3-4 F G Replace dirt cup lid. Slide cup straight into cleaner cavity. Bottom of cup will rest behind grooves at bottom of cleaner cavity (G). Push latch (F) to the right to lock in place. Filter assembly The HEPA cartridge filter and pre-filter are essentially self-shedding. Tapping the side of the dirt cup as described in "How to empty dirt cup" should sufficiently remove dust and fine particles from the HEPA cartridge filter and pre-filter. The filter assembly can also be removed for additional cleaning. 3-5 How to clean filter assembly Remove dirt cup and dirt cup lid as described in "How to empty dirt cup."
