Abstract
A method of operating a waste collection unit including a light assembly separate from a display panel. A vacuum level of the vacuum drawn on a waste canister is measured with a vacuum sensor. The light assembly positioned adjacent a manifold receiver is operated to selectively emit light of a color based on the measured vacuum level. A commanded vacuum level may be received on the display panel, and a colored image indicative of a commanded vacuum level may be displayed on the display panel. The waste collection unit may include plural manifold receivers each configured to receive a manifold. The light assembly that is adjacent the manifold receiver corresponding to the waste canister into which the vacuum is being drawn may be operated to selectively emit light to emit light at different colors or different patterns based on the operating state of the waste collection unit.
