  If your Laerdal Laboratory Equipment LSU operates but provides little to no suction, consider these possible causes and solutions: * If the vacuum seal is blocked by the float ball, unplug the vacuum seal to release the vacuum. * If the canister is full, you should remove and replace it. * Check the vacuum connection between the pump unit and the canister, ensuring the vacuum connector tubing is correctly installed. * Inspect the patient suction tubing for twists or blockages; untwist the tubing, clear any blockages, or replace the tubing. Replace the filter or liner if the filter is blocked. * If using a Serres canister, ensure the lid is properly sealed using vacuum, not force.
