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 (80 psig/
551.5 kPA) recommended pressure, obtain a water
pressure regulator from your Manitowoc distributor.
•
Install a water shut-off valve and union for both the
ice making and condenser water lines.
•
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 water-cooled condenser 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. Do not vent the condenser drain on water-
cooled models.
•
Drains must have a union or other suitable means to
allow in place disconnection from the ice machine
when servicing is required.
