Requirements for plumbing The water supply system needs to be installed as follows: Connect the ice machine to the cold potable water supply using a 1/4" water supply hose with a 3/8"MPT connector. A shut off valve is recommended between the water supply and the ice maker. If the tap water has a high mineral content(hard water) a water filter is highly recommended. The pressure of the tap water should be maintained at a level between 20psi (1.0bar) and 80psi (4.9bar).
Gravity Drain Model Shut-Off Valve Drain Tube Water Filter 24"(610) Locate drain within 2" DIA. Area 23" back from front of unit Before connecting the drain and water supply hoses, check the following: The drain hose must drop a 1/4" for every foot in length to allow for adequate draining. An air gap is required between the drain hose and the floor drain to prevent backflow into the ice storage bin.
