Sizing
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 ice 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
affect 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.
Installation Hints
Dimensions
Be sure components will fit through doorways, down halls, and into the
installation space. Once installed, most ice machines must have at least
5" to 8" of clearance above, behind and on both sides.
Location
Locate the ice machine in an area where the ambient
air temperature stays between 35°F. and 110°F.
Connections
Electrical and water connections must be within 6' 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 33°F., maximum 90°F.
• Ice making water pressure: minimum 20 psi, maximum 80 psi.
• Condenser water pressure (water-cooled models): minimum 20 psi,
maximum 150 psi.
• Use separate drain lines for ice machine and storage bin.
• Ice machine drain tubing: 1⁄2" minimum I.D.
• Bin drain tubing 3⁄4" 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.
