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

The ice maker and water dispenser require a water pressure between 20 psi and 125 psi (138 and 862 kPa) to operate properly. Make sure the refrigerator is connected only to a potable water supply. If water is not dispensing properly, the water filter may be clogged and should be replaced. (Page 7, 66)
