Typical Refill Periods
TheAC3refillperiodsrangegreatly,dependingonthenumberofpumpingunits,theoutputquanes,andthe
programmeddelaymes.Duetotheaccuracyofthepumpingunitsoutputquanesandthereliabilityofpump
funconalityrefillperiodscanbesimplycalculatedtoensurethatthepumpandthebearingpointsdon’trundry.
