Model UC-15I (Undercounter Ice Machine)
Installation Information
2-5
#7012423 - Revision B - May, 2011
PLUMBING REQUIREMENTS
NOTE: Plumbing must conform to state and local
codes.
Water Supply
Prepare water supply line and drain before installation
of the ice machine. Installation requires a minimum
1/4” ID copper cold water line and compression fitting
(not supplied). Models UC-15I and UC-15IO are sup-
plied with a drain hose for gravity draining. The option-
al drain pump or pump models UC-15IP and UC-15IPO
must be purchased if a gravity drain is not possible.
Both drain methods require routing to an open site
drain. Do not connect directly to drain line as bacteria
from drain line may contaminate the ice machine.
The included water filter is designed to inhibit scale for-
mation, filter sediment, and remove chlorine odor and
taste. The life expectancy of the water filter is 6 months
during normal usage. The ice machine control board
will monitor water usage and indicate when replace-
ment is required.
Water Inlet Lines
Follow these guidelines to install water inlet lines:
• Do not connect the ice machine to a hot water supply.
Be sure all hot water restrictors installed for other
equipment are working. (Check valves on sink
faucets, dishwashers, etc.)
• If water pressure exceeds the maximum recommend-
ed pressure (80 psi–551.5 kPA), obtain a water pres-
sure regulator from a local plumbing contractor.
• Install a water shut-off valve for the ice making water
lines.
• Insulate the water inlet line to prevent condensation.
Drain Connections
Follow these guidelines when installing drain lines to
prevent drain water from flowing back into the ice
machine and storage bin:
• Drain lines must have a 1-1/2” drop per 5 feet of run
(2.5 cm per meter), and must not create traps.
• The floor drain must be large enough to accommo-
date drainage from all drains.
• Drain pump discharge line must terminate at an open
site drain.
• Maximum rise – 12 feet (3.7 m)
• Maximum run – 100 feet (30.5 m).
APPROXIMATE HEIGHT OF
ICE MACHINE DRAIN
Standard Installation 5” (127mm)
Improper drainage can lead to water flowing back
into ice machine and poor performance.
