A minimum supply pressure of 35 psig for water filter units is required. Minimum pressure requirement ensures that
water valves close and sufficient water volume is available to fill icemaker. Proper fill is 140 cc. of water in 7.5
seconds. Failure of water valves to close because of low pressure will result in fill-tube freeze-up or dripping at
cavity.
