Operation 6 Operation 6.1 Before switching on the pump Check the operating fluid level in the sightglass. Compare the voltage and frequency information on the rating plate with the mains voltage and frequency values. Check that the exhaust connection allows free flow (max. permissible pressure 1.5 bar absolute). - Page 14 Set flushing gas pressure; maximum pressure 1.2 bar (absolute). – Select the type and amount of flushing gas depending on the process; consult Pfeiffer Vacuum if necessary. Use the proportioning screw 7.3 to set the desired amount of gas.
