      If the drain of your Tuttnauer Laboratory Equipment is clogged: 1. Open the drain by turning it counterclockwise and place a heavy object over the reservoir cover. 2. Blow compressed air into the drain to force debris back into the reservoir, then clean out the reservoir. 3. Alternatively, disassemble the drain valve, clean it, and blow out the line. Reassemble the valve, ensuring the large 'O' ring is properly seated.
