Prepare water supply line and drain before
installation of your 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 supplied with
a drain hose for gravity draining. The optional
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 formation, 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
replacement is required.

Follow these guidelines to install water inlet
lines:
Do not connect the ice machine to a hot
water supply. Be sure all hot water restric-
tors installed for other equipment are
working. (Check valves on sink faucets,
dishwashers, etc.)
If water pressure exceeds the maximum
recommended pressure (80 psi–551.5 kPA),
obtain a water pressure regulator from your
local plumbing contractor.
Install a water shut-off valve for the ice
making water lines.
Insulate the water inlet line to prevent
condensation.

" drop per 5
feet of run (2.5 cm per meter), and must
not create traps.
The floor drain must be large enough to
accommodate drainage from all drains.
Drain pump discharge line must termi-
nate at an open site drain.
Maximum rise – 12 feet (3.7 m)
Maximum run – 100 feet (30.5 m)

Plumbing must
conform to state
and local codes.
Improper drainage can lead to water
flowing back into ice machine and poor
performance.
