Page 32: Gas Ballast Valve With Inert Gas Connection
► After switching off the vacuum pump, close the supply of inert gas at the gas ballast valve or by closing the on-site gas supply. If you optionally use inert gas in the process, Pfeiffer Vacuum recommends using the gas ballast valve with inert gas connection. Admission of inert gas dilutes the process gas and avoids condensation of vapors in the vacuum pump within certain limits. -
Page 33: Refilling Operating Fluid
Establishing inert gas supply 1. Select the type and quantity of the inert gas used according to the specific process. – Consult Pfeiffer Vacuum if necessary. 2. Set the inert gas pressure to max. 1500 hPa (absolute). 3. Make sure that the inert gas pressure is greater than the respective intake pressure. -
Page 34: Switching Off Vacuum Pump
► 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. - Page 35 Operation Procedure 1. If required, switch the vacuum pump off in each pressure range. 2. Switch the mains switch off or securely disconnect the drive motor from the mains. – The vacuum safety valve closes automatically when the vacuum pump is switched off, pre- venting the backflow of gas and operating fluid into the intake line.

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. This also applies if original spare parts are not used. -
Page 38: Change The Operating Fluid
► Wear protective equipment. ► Use a suitable collection receptacle. Pfeiffer Vacuum recommends determining the precise service life of the operating fluid within the first maintenance frequency. The usable 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. -
