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

The ice maker and water dispenser require a water pressure of 20 to 125 psi (138 to 862 kPa) to operate properly. Under normal conditions, a 170 cc (5.75 oz.) cup can be filled in about 10 seconds. If water pressure is below 20 psi, a booster pump can be installed to compensate. (Page 9)
