Page 17: Transport And Storing
When a pump is put into operation after it has been stored for over one year, standard maintenance should be run on the pump and the oil should also be exchanged. We recommend that you contact the Leybold Service. GA01601_002_C1 - 03/2018 - © Leybold... -
Page 18: Installation
The standard pump is not suited for installation in the explosion hazard areas. Observe Safety Informations 0.5. The TRIVAC D 2,5 E-LD pump can be set up on a flat, horizontal surface. Rubber feet under the coupling housing ensure that the pump can not slip. -
Page 19: Normal Use
The pumps are not suited for pumping of liquids or media which carry large quantities of dust. Corresponding protection devices need to be pro- vided. Our technical sales department is available for further advice in these matters. GA01601_002_C1 - 03/2018 - © Leybold... -
Page 20: Abnormal Use

Page 22: Electrical Connection
Observe Safety Informations 0.2. Operation Media Compatibility The TRIVAC D 2,5 E-LD pump can pump condensable gases and vapours, provided that the gas ballast valve is open and the pump has attained its operating temperature. Start-up Check the oil level each time before switching on the pump, see Section 5.3. -
Page 23: Operation
Observe Safety Informations 0.1. Operation The TRIVAC D 2,5 E-LD pump is capable of pumping gases and vapours. For pumping vapours it is required that the gas ballast valve be open (5/7) and that the pump has attained its operating temperature. -

Page 29: Monitoring The Oil Level
Check and top up oil only after having shut down the pump first. Please note the safety information given in Section 0.3 and 0.4. Pumps which have not directly been delivered from Leybold, e.g. in systems, may have been filled with oils different from LVO 310. In this case a refill with LVO 310 may cause problems. -
Page 30: Oil Change
When disposing of waste oil, observe the applicable environment pro- tection regulations! When changing the oil use the same type of oil which was previously in the pump. If you want to change the type of oil entirely please consult us first.
