Sub-Zero UC-15IO Ice Maker Installation Guide - Page 7

Ice Machine Specifications 7 subzero.com/specs Plumbing Requirements DRAIN CONNECTION Models UC-15I and UC-15IO are gravity drain models that require a drain tube that is pitched down from the outlet at the back of the unit to the sanitary sewer connection. Models UC-15IP and UC-15IPO have a built in drain pump that will pump water up to a drain point, such as a sink. Gravity drain models are supplied with a drain hose for gravity draining. A pump model must be used if a gravity drain is not possible. Both drain methods require routing to an open site drain. Do not connect directly to a drain line as bacteria from the drain line may contaminate the ice machine. Locate the drain in an adjacent cabinet. Refer to the illustrations below. For installations that will not allow the drain to be placed in an adjacent cabinet, the drain must be located within 1/2" (13) of the back wall. Improper drainage can lead to water flowing back into ice machine and poor performance. SHUT-OFF VALVE WATER SUPPLY DRAIN TUBE SHUT-OFF VALVE AIR GAP DRAIN TUBE WATER SUPPLY • The ice machine drain connection is approximately 5" (127) from the floor. • For the gravity drain, all horizontal runs of drain lines must have a 1/4" (6) per 12" (305) fall. • Drain pump models have a maximum rise of 12' (4 m) and a maximum run of 100' (31 m). • Drain pump models will likely require an air gap between the unit and the drain receptacle. • The floor drain must be large enough to accommodate drainage from all drain lines. • The drain pump discharge line must terminate at an open site drain. • If there is not adequate room behind the ice machine for the drain or waste water receptacle, the drain can be located below the floor. WATER FILTER The water filter provided with the ice machine is designed to inhibit scale formation, filter sediment, and remove chlorine odor and taste. The life expectancy of the water filter is approximately six months during normal usage. The ice machine control board will monitor water usage and indicate when replacement is required. Replacement water filters are available through your authorized Sub-Zero dealer. For local dealer information, visit the find a showroom section of our website, subzero.com. Gravity drain models.
