4.2.4 Checking the Waste Tank Seal
The vacuum pump to waste tank seal plays a critical role in the cleaning function of the
Phoenix LT4 and should be inspected weekly. Any nicks or cuts, bent or rolled edges,
excessively frayed or abraded areas, or lack of adhesion to the vacuum pump will impede
the cleaning function. Refer to Section 4.4.4 – Replacing the Waste Tank Seal.
Additionally, any gap between the seal and waste tank will adversely affect cleaning
efficiency. If a gap exists, refer to Section 4.3.6 – Adjusting the Vacuum Motor Position.

by completing the steps below. Perform these steps with the machine in the operating
position.
1. Disconnect the vacuum hose and remove the waste tank from the Phoenix LT4.
2. Pour a few drops of cleaner into the waste tank and add water until the waste tank
is about half full.
3. Carefully swish around the solution in the waste tank. Be sure to get the upper
corners and around the intake opening.
4. Empty the cleaning solution from the waste tank. Do NOT dump recovery tank in a
septic tank or sanitary sewer system. Follow your local environmental regulations
for the best method of disposal. Rinse the waste tank under running water.
