Installation Instructions Section 2
Water Service/Drains
WATER SUPPLY
Local water conditions may require treatment of the
water to inhibit scale formation, filter sediment, remove
chlorine, and improve taste and clarity.
Important
If you are installing a water filter system, make
sure that you use a separate line for water-cooled
condenser. Filter life will be greatly reduced if filtered
water is used for a water-cooled condenser.
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.)
• Water pressure to the machine should be between
1.4 and 5.5 bar (20 and 80 psi).
• If water pressure exceeds the maximum 5 bar
recommended pressure, obtain a water pressure
regulator from your Manitowoc distributor. Adjust
pressure to 2.5 bar (37 psi).
• Install a water shut-off valve.
• Connect to a potable water supply only.
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 3.8 cm drop of run for each
meter (1.5 inch for 3 feet), 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 by
temperature.
