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 Manitowoc Tri-Liminator
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

Insulate water lines to prevent condensation.
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 drop per 1 meter of
run (1.5 inch per 5 feet), 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.
