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:
• Plumbing must conform to state and local codes.
• 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 - 55 bar), 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)
