MC0322 through MC2148 Air, Water, and Remote Cooled Service Manual Introduction This technical manual covers the Prodigy line, excluding the Eclipse remote low side models. All are shipped with an Installation and User's manual, which can be referred to separately. General installation information is included in this manual.
Testing has shown that using a filter that does not remove chlorine, such as the Scotsman Aqua Patrol, will greatly improve this situation, while the ice making process itself will remove the chlorine from the ice, resulting in no taste or odor impact.
