Filter Installation
The type of filter required depends on whether you are performing wet or dry vacuuming.
For Dry Vacuuming: Reusable Cloth Filter
For dry debris collection, install the reusable cloth filter. This filter is designed to capture fine dust and particles.
- Ensure the foam wet filter is removed if previously installed.
- Slide the reusable cloth filter over the filter cage, ensuring it covers the entire cage and the rubber gasket is seated properly at the base.
- Secure the filter with the filter clamp if provided, or ensure it fits snugly.
For Wet Vacuuming: Foam Wet Filter
For liquid collection, use the foam wet filter. This filter protects the motor from liquids.
- Remove the reusable cloth filter if previously installed.
- Slide the foam wet filter over the filter cage, ensuring it covers the entire cage.
- No clamp is typically needed for the foam filter; it should fit snugly.
Important: Never use the reusable cloth filter for wet vacuuming, as it can be damaged and compromise motor protection. Always remove the foam filter for dry vacuuming to ensure optimal suction and prevent clogging.
