WATER SERVICE/DRAINS

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.

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, 80 psig (5.5 bar) obtain a water pressure regulator from your Manitowoc distributor.

•Install a water shut-off valve for ice making potable water.

•Insulate water inlet lines to prevent condensation.

•Local, state or city codes may require an air gap. Contact a local plumber for code requirements.

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.
