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 pre- filter 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 car- tridge 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 suc- tion. When using the cleaner for this type of dust, empty the cup and clean the filters often.
