In any business, ice needs are rarely uniform.
For example, more ice is needed in summer
than in winter and on weekends than on
weekdays. Size your Manitowoc machine and
storage bin to meet your peak needs.
Avoid sizing a new ice machine solely on the
performance of your present equipment.
The age and mechanical condition of your
present ice machine may mislead you in
determining the production capacity you need.
Remember, surrounding air and incoming
water temperatures aect the quantity of ice a
machine produces.
Determine what these temperatures will be
during times of peak usage, then verify your
selection from the machine’s production chart.
The Ice Usage Guide will help you calculate
your production requirements based on your
peak needs. After calculating how much ice
you expect to need, add 20% to accommodate
future business growth. Taking the
time to correctly size ice making
equipment assures ample ice supply
during peak periods.

Dimensions
Be sure components will t through doorways, down halls,
and into the installation space. Once installed, most ice
machines must have at least 5” (12.7 cm) to 8”
(20.3 cm) of clearance above, behind and on both sides.
Location
Locate the ice machine in an area where the ambient
air temperature stays between 40 F (4.4 C) and 110°F
(43.33°C).
Connections
Electrical and water connections must be within 6’
(183 cm) of the ice machine. Connections must meet local,
state, and national codes.
Plumbing Requirements
• Ice machine must be connected to cold water supply.
• Water temperature: minimum 40 F (4.4 C), maximum
90°F (32.22°C).
• Ice making water pressure: minimum 20 psi, maximum
80 psi.
• Condenser water pressure (water-cooled models):
minimum 20 psi, maximum 150 psi (276 psi for Indigo
NXT).
• Use separate drain lines for ice machine and storage bin.
• Ice machine drain tubing: 1/2” (1.27 cm) minimum I.D.
• Bin drain tubing 3/4” (1.9 cm) minimum I.D.
• Ice-making water drain and bin drain must be vented to
the atmosphere. Do not vent condenser drain on water-
cooled models.
