WATER SUPPLY
Local water conditions may require treatment of the
water to inhibit scale formation, filter sediment, and
remove chlorine odor and taste.
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.
Follow these guidelines to install water inlet lines:
• Connect to potable water supply only.
• 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 (if applicable).
• Insulate water lines to prevent condensation.
Important
The water inlet line is connected to the water valve.
This valve is located just behind the front panel of
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 2.5 cm (1 inch) drop per
1 meter (40 inches) of run, and must not create
traps.
• The floor drain must be large enough to
accommodate drainage from all drains.
• Insulate the bin drain line to prevent
condensation.
