Page 28: Connecting The Intake And Exhaust Lines
When choosing and installing the vacuum pumps for harsh processes or for processes of special applications, like harsh furnace process, toxic or explo- sive gas process, please check in advance with the engineers of Leybold; when necessary, we suggest installing a trap at the pump inlet or outlet port to prevent any safety accidents. - Page 29 In order to prevent deposits in the exhaust lines it may be necessary to heat the exhaust lines. Run the exhaust line only by way of a fixed installation to the outside and/or connected to a silencer. 300407956_002_C1 - 01/2017 - © Leybold...

If during longer downtimes the system shall remain conditioned for a rapid pumpdown, we recommend to vent the system with dry nitrogen to atmos- pheric pressure and maintain it in this condition without opening it. 300407956_002_C1 - 01/2017 - © Leybold... -
Page 49: Removing From Service
Blow out the cooling water coils with compressed air or Nitrogen (max. 4 bar). Blow into the cooling water inlet port only. Drain the lubricant (PFPE or synthetic oil) out of the pump (cf. Fig. 5.1). Drain lubricant 300407956_002_C1 - 01/2017 - © Leybold... - Page 50 Unscrew the drain plug. Tools and bucket must be clean so as not to further contaminate the lubricant. Screw the drain plug with the sealing ring back in, wipe off any dripped lubri- cant from the casing. 300407956_002_C1 - 01/2017 - © Leybold...

Page 51: Maintenance
In clean processes, you may increase the maintenance intervals; in harsh processes, you may have to decrease them. We recommend a service contract with Leybold. We recommend to inspect the pump system and all components after approximately 6 months under the process conditions. The inspection of the components shall let corrosion attacks become apparent at an early stage and indicate possible deposits of process dust. - Page 52 Disposal of process byproducts, lubricating oil, vacuum grease and other wastes must be in strict accordance with all local and national environmen- tal and safety regulations. For further info see Section 7 Waste Disposal. 300407956_002_C1 - 01/2017 - © Leybold...

Page 59: Waste Disposal
Waste oil from vacuum pumps must not be mixed with other substances or materials. Waste oil from vacuum pumps (Leybold oils which are based on mineral oils) which are subject to normal wear and which are contaminated due to the influence of oxygen in the air, high temperatures or mechanical wear must be disposed of through the locally available waste oil disposal system. -
