Water Service/Drains

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, obtain a water pressure regulator from your Manitowoc distributor.

•Install a water shut-off valve for both the ice making and condenser water lines.

•Insulate water inlet lines to prevent condensation.

•Use teflon tape to seal threaded fittings.

Important

Install sump trough drain plug before starting 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 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.

•Run separate bin and ice machine drain lines. Insulate them to prevent condensation.

•Vent the bin and ice machine drain to the atmosphere. Do not vent the condenser drain on water-cooled models.

CAUTION

Plumbing must conform to applicable codes.
