Water Supply and Drain Requirements
WATER SUPPLY
Prepare water supply line and drain before installation of
your ice machine. Installation requires a 1/4" ID copper
cold water line and compression fitting (not supplied).
The ice machine is supplied with a drain hose for gravity
draining. The optional drain pump 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.
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
recommended pressure (80 psi/552 kPA), obtain a
water pressure regulator from your Manitowoc
distributor.
•
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 1.5 inch 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 terminate at an open
site drain.
•
Maximum rise - 12 feet (3.7 m)
•
Maximum run - 100 feet (30.5 m)
