Make sure your tank is empty.
- If you're DRY Vacuuming ONLY, check that your cartridge filter is properly mounted. Remove your power head and turn it upside down, then push the filter until it stops against the power head and install the retainer.
- Once the filter is installed, flip the powerhead and place it over the recovery tank, and lock it in place using the latches on the side.
CAUTION: Do not use the dust filter for vacuuming liquids, it will lead to the motor burning and a void warranty.
