NOTICE Property damage from the voltage range being set incorrectly Recommissioning after longer downtimes of the vacuum pump or after changing the oil requires the...
Vacuum are also excluded. ► Only use approved operating fluids. ► Only use other application-specific operating fluids after consultation with Pfeiffer Vacuum. The type of operating fluid specified, as well as the filling quantity for the entire rotary vane vacuum pump, are shown on the rating plate.
► Install suitable touch protection if the vacuum pump is accessible to untrained persons. ► Allow the vacuum pump to cool down before carrying out any work. ► Contact Pfeiffer Vacuum for suitable touch protection in system solutions. 29/60...

Operation geöffnet/ open geschlossen/ closed Fig. 11: Gas ballast valve Behavior with process gases with condensable vapors ► Operate the vacuum pump with gas ballast, i.e. with the gas ballast valve open. Open gas ballast valve ► Rotate the knob on the gas ballast valve to the left to open, into position “1”. Close gas ballast valve ►...
► Shut off the intake line with an additional shut-off valve, after the vacuum pump is switched off during longer venting operations. Pfeiffer Vacuum rotary vane pumps have an integral vacuum safety valve on the intake side. The vac- uum safety valve automatically closes from a differential pressure of ≥250 hPa between the exhaust and intake sides, when the vacuum pump is switched off, and vents the vacuum pump.
► Dismantle the vacuum pump for inspection, away from the system if necessary. NOTICE Danger of property damage from improper maintenance Unprofessional work on the vacuum pump will lead to damage for which Pfeiffer Vacuum accepts no liability. ► We recommend taking advantage of our service training offering.
You can carry out maintenance work at Maintenance Level 1 yourself. We recommend Pfeiffer Vacuum Service for carrying out maintenance work of Maintenance Level 2 and Maintenance Level 3 (revision). If the required intervals listed below are exceeded, or if mainte- nance work is carried out improperly, no warranty or liability claims are accepted on the part of Pfeiffer Vacuum.
► Wear protective equipment. ► Use a suitable collection receptacle. Pfeiffer Vacuum recommends determining the precise service life of the operating fluid in the first operating year. The service life may deviate from the reference value specified depending on thermic and chemical loads, and the accumulation of suspended particles and condensate in the oper- ating fluid.
Should process conditions change, you can convert to a different operating fluid type. Safety data sheets You can obtain the safety data sheets for operating fluids from Pfeiffer Vacuum on request, or from the Pfeiffer Vacuum Download Center.
► Wear protective equipment. ► Use a suitable collection receptacle. Cleaning by changing the operating fluid Pfeiffer Vacuum recommends, in cases of heavy contamination with process residues, cleaning the inside of the vacuum pump with several operating fluid changes. Prerequisites ●...
