The cleaning solution and oil absorbent sock can normally be replaced at the same time. The oil absorbent sock will hold 2 L (2.1 qt) of oil, and may not need replacement each time the cleaning solution is replenished.
The cleaning solution can be removed from the basin by connecting a regulated air supply and pumping the old cleaning solution through the flexible nozzle into a suitable receptacle. Stop pumping before the level of the cleaning solution reaches the pump pickup inside the basin.Note: Follow all Local, State, and Federal guidelines for the disposal of used cleaning solution.
Disconnect the air supply and carefully pour the remaining solution into the receptacle. Follow all local, state, and Federal laws and regulations for the proper disposal of used cleaning solution.
Any remaining sediment can be wiped out with disposable towels.
Place the 212-1504 Oil Absorbent Sock in the bottom of the basin. Position the sock towards the end of the basin with the pump intake, as shown.

Note: The blanket microfilter only allows cleaning solution to flow through in one direction. Make sure that the blanket microfilter is installed with the folded edge facing down.
Carefully pour 1 L (1.1 qt) of concentrated water-based cleaner through the blanket microfilter, into the basin. Add 12 L (3.2 US gal) of water to bring the level up to just below the filter. Pouring through the blanket microfilter prevents the liquid from splashing.Note: A 1/10th percent solution of 1U-8806 Bactericide (Hydrosolv 174) can be added to the cleaning solution. This will help prevent the growth of bacteria and the resulting unpleasant odors.
RV antifreeze can be used in place of water. In cold-weather conditions, RV antifreeze will prevent the cleaning solution from freezing and damaging the portable parts washer. For information on solvent/cleaning solution, refer to the Contact Information section in this manual.
