Ice Machine Head Section Water Supply
and Drains
POTABLE WATER SUPPLY
Local water conditions may require treatment of the
water to inhibit scale formation, filter sediment, and
remove chlorine odor and taste.
POTABLE 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, obtain a water pressure
regulator from your Manitowoc distributor.
Float Valve - 80 psig (551.5 kPA)
• Install a water shut-off valve for ice making potable
water.
• Insulate water inlet lines 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.
• Run separate bin and ice machine drain lines.
Insulate them to prevent condensation.
• Vent the bin and ice machine drain to the
atmosphere. The ice machine drain requires an 18”
vent.
Water Cooled Condenser Water Supply and
Drains
CONDENSER WATER SUPPLY
Local water conditions may require treatment of the
water to inhibit scale formation, filter sediment, and
remove chlorine odor and taste.
WATER COOLED CONDENSER LINES
Follow these guidelines to install water lines:
• Contact your distributor if your water pressure is
greater than 150 psig (1034 kPA). A special order
condensing unit is available that allows water
pressure up to 350 psig (2413 kPA).
• Install a shutoff valve (inlet and outlet on cooling
tower or closed loop circuits) to allow isolation of the
water system.
• Water entering the condenser must not exceed 90°F
(32.2°C).
• Water flow through the condenser must not exceed 5
gallons (19 liters) per minute.
• Allow for a pressure drop of 8 psig (55 kPA) between
the condenser water inlet and outlet.
• Water exiting the condenser must no exceed 110°F
(43.3°C).
CONDENSING UNIT DRAIN CONNECTIONS
The condensing unit drain is provided to remove any
condensate produced by the suction accumulator.
Condensate amounts will vary depending on
temperature and humidity.
• The condensing unit must be level front to back and
side to side to allow the condensate to drain.
• Drain lines must have a 1.5-inch drop per 5 feet of
run (2.5 cm per meter), and must not create traps.
• Drain termination must meet applicable costs.
Important
If you are installing a Manitowoc water filter system,
refer to the Installation Instructions supplied with the
filter system for ice making water inlet connections.
