What water pressure is required for the ice maker and water dispenser to work?

A cold water supply with water pressure between 30 and 120 psi (207–827 kPa) is required to operate the water dispenser and ice maker. If you have a reverse osmosis system, the pressure coming out of it going to the refrigerator's water inlet valve must also be between 30 and 120 psi. If you have questions about water pressure, call a licensed, qualified plumber. (Page 4)
