Page 30: Operation
Operation 6 Operation 6.1 Commissioning vacuum pump WARNING Danger of poisoning due to toxic process media escaping from the exhaust pipe During operation with no exhaust line, the vacuum pump allows exhaust gases and vapors to escape freely into the air. There is a risk of injury and fatality due to poisoning in processes with toxic process media. -
Page 31: Operating Rotary Vane Pump With Gas Ballast
Operation Switching on the pump 1. Switch the pump on at the mains switch. 2. Close the vacuum flange and gas ballast valve. 3. Allow the pump to warm up prior to process start, with the vacuum flange closed, for approximate- ly 30 minutes. -
Page 32: Gas Ballast Valve With Flushing Gas Connection (Option)
1. Connect the hose (DN 5 mm) to the flushing gas connection. 2. Select the type and quantity of the flushing gas used according to the process. 3. Consult Pfeiffer Vacuum if necessary. 4. Set the flushing gas pressure to max. 1,500 hPa (absolute). -
Page 33: Operation With Flushing Gas
4. Open the shut-off valve on the vacuum flange.
