Use the following procedure to clean the collection bin:
1. Open the toggle fasteners on the bottom of the filter
2. Remove the collection bin.
3. Empty contents of the collection bin and completely clean it.

open from 3/16” to 1/4” (4 mm to 6 mm) when not under vacuum.
5. Wipe down the gasket and collection bin mating surfaces to ensure a good seal. A
good vacuum seal is important for proper operation. Replace gasket if necessary.
