Topics:

• Is a UC-15I (gravity drain) drain tube coming out of the unit 3/4" inside or outside diameter?
• Is a UC-15IP (drain pump) drain tube coming out of the unit 3/8" inside or outside diameter?
• Does the UC-15I or UC-15IP come with a supplied drain line?
• What size water outlet drain line should be used on the UC-15I or UC-15IP Undercounter Ice Maker?
• What is the maximum length of drain line allowed?
• Undercounter Ice Maker plumbing requirements and max length drain

Answer:

The water outlet size on an Undercounter Ice Maker depends on the unit's drain method:

• The drain line on the UC-15I (gravity drain) is a 3/4" ID hose.
  • A 5' PEX tube is provided for drainage.
  • This drain line can be cut to size if needed. If a longer drain line is required, disconnect the provided line and install one of adequate size to avoid multiple connection points.
• The drain line on the UC-15IP (drain pump) is a 3/8" ID hose.
  • A 5' PVC drain tube is provided for drainage.
  • This drain line can be cut to size if needed. If a longer drain line is required, disconnect the provided line and install one of adequate size to avoid multiple connection points.
• 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 maker.
• Follow local codes for all plumbing connections.
• Maximum drain line length is 100' for pump model, with a maximum 12' rise.
• For the gravity drain, horizontal drain lines must have a 1/4" (6) per 12" (305) fall.
