1 Introduction 1.1 Overview This manual describes the software setup and sequence for operating the Vacuum Assisted Priming Routine (VAPR). VAPR is designed for use with the DJ-9000 Series DispenseJet and is available on the M-2000 and S-900 Series Dispensing System platforms. Refer to the DJ-9000 Owner's Manual (P/N 7200530) for detailed instruction on valve operation. 1.
2 Running the VAPR Procedure 2.1 Overview Priming commands are executed through the Fluidmove software. Prior to running the VAPR routine, the Fluidmove software must be configured properly. The VAPR procedure can be run manually from the Fluidmove Production Window or the Fluidmove Programming Window, but is most effective when launched automatically during the valve offset routine. This section covers the following topics: • Fluidmove Configuration • Running the VAPR Procedure WARNING! 2.
