Page 31: 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 32: Operating Rotary Vane Pump With Gas Ballast
► 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. NOTICE Risk of damage to the drive from increased motor current consumption At an intake pressure of approximately 300 hPa and under unfavorable operating conditions (such as for example exhaust side counterpressure), the power input exceeds the rated current. -
Page 33: Gas Ballast Valve - Standard Version
An intermediate setting between open and closed is not possible. For some processes, Pfeiffer Vacuum recommends the addition of inert gas to dilute the process gas and, within certain limits, prevent condensation in the vacuum pump. The inert gas connection is inte- grated as standard equipment or is a possible option. -
Page 34: Refilling Operating Fluid
2. Connect a hose (external diameter 6 mm) to the inert gas connection, or utilize the M5 threaded connector directly. 3. Select the type and quantity of the inert gas used according to the specific process. 4. Consult Pfeiffer Vacuum if necessary. 5. Set the inert gas pressure. – Observe the max. permissible inert gas pressure. -
