Installation 4. Remove the blanking plates used to seal the inlet and exhaust ports. 5. Keep the blanking plates, screws and washers for reuse when transporting the pump. 6. Ensure that no screws, washers or other objects are dropped into the pump inlet. 7. -
Page 19: Connecting Cp Version Pumps
The gas purge consists of injecting an inert gas into the pump. In this manual, the inert gas will be called ‘nitrogen’, as it is the most commonly used gas. For more information about the type of purge gas, contact your Pfeiffer Vacuum service center. DANGER Danger of death by explosion when pumping gases containing pyrophoric/flammable materi- There is a risk of explosion if pyrophoric materials above the LEL are sent to the pump. -
Page 20: Check That The Installation Is Leaktight
Installation LG version The air injection line flow rate is ensured by a jet, which is integrated into the pump. 5.3 Check that the installation is leaktight When the product leaves the factory, product leaktightness under normal operating conditions is guar- anteed. -
Page 21: Customer Electrical Installation Protection
Installation The pump has thermal sensors that prevent start-up at certain temperatures (see chapter “Preliminary precautions for use”). 5.4.1 Customer electrical installation protection The pump is connected to the mains with the mains power cable provided. The earth connection (fre- quency converter, cover, pump) is made via the power cable connected to a compliant electrical instal- lation. -

● Do not drain the pump: this operation is carried out during pump overhaul by our serv- ice centers. 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. -
Page 28: Matrix Gas/Applications
Operation 4. Check that the inlet pressure is not higher than atmospheric pressure. If the pressure is too high, it can damage the product. 5. Check that the ambient temperature is well within the permitted operating range. 6. Check the exhaust line during pumping to prevent the risks related to excess overpressure. 6.2 Matrix gas/applications You are advised to use the appropriate pump version according to the applications and the nature of the gases pumped and apply the usual precautions to guarantee the reliability and safety of the procedure. -

Page 32: Purge Operation
Operation beyond its saturated vapor pressure in the compression phase. It can condense, impairing pump per- formance. The gas ballast can be used to inject a certain quantity of air (neutral or dry gas) into the pump during the ‘compression’ phase so that the partial pressure of the pumped gas is less than its sa- turated vapor pressure at the pump’s operating temperature. - Page 33 Operation The combined use of the gas ballast and the purge allows large amounts of condensable vapors to be removed. Commissioning To better pump with condensable vapors or moist air, it is necessary to operate with a hot pump and to use a nitrogen supply with the required characteristics (see chapter “Nitrogen characteristics”).
