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 and condenser water lines (if applicable).

Insulate water lines to prevent condensation.

Important

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 (1 inch) drop per 1 meter (40 inches) of run, 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.
