NOTE: DeVilbiss recommends the use of distilled water in the DV6
water chamber.

additives in the distilled water.

detergent. Rinse thoroughly and allow the parts to air dry before
reassembly.
NOTE: The disassembled chamber may also be washed once per
week in a dishwasher on the delicate or glassware cycle, top shelf
only.
NOTE: If the sealing gasket was removed for cleaning, replace
gasket into its groove around the top of the chamber ensuring that it is
snapped under the 12 ribs.

that it is not damaged and is properly seated under the ribs and in the
groove around the entire chamber.
