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.

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 to 5.5
bar (20 to 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
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 water-cooled condenser.
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 (1.5 inch) drop of run for
each meter (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
