Water Connections
• Local water conditions may require
treatment of the water to inhibit scale
formation, filter sediment, and remove
chlorine odor and taste.
• Connect ice making water inlet to
potable water only.
• Install a water shut-off valve for potable
water and water cooled condenser lines.
• Do not connect the ice machine to a hot
water supply. Verify hot water restrictors
installed on other equipment are
functioning correctly. (Check valves on
sink, faucets, dishwashers, etc.)
• Install a water regulating valve if water
pressure exceeds the maximum valve
rating.
• Insulate water and drain lines to prevent
condensation.
