Water Service/Drains
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.
• Install a water shut-off valve for both the ice
making and condenser water lines.
• Insulate water inlet lines to prevent condensation.
• Use teflon tape to seal threaded fittings.
Important
Install sump trough drain plug before starting the
ice machine.
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. Do not vent the condenser drain on
water-cooled models.
CAUTION
Plumbing must conform to applicable
codes.
