TRIVAC NT through the exhaust port. During compression, a controlled amount of air - the so-called gas ballast - can be allowed to enter the pump chamber by opening the gas ballast valve 130002780_002_A0 - 12/2008 - © Oerlikon Leybold Vacuum... - Page 16 (1.4/6) against its seat. This effectively prevents backstreaming of oil. The anti-suckback valve (1.2/3) operates independently of the opera- ting mode of the pump, i.e. also with gas ballast. 130002780_002_A0 - 12/2008 - © Oerlikon Leybold Vacuum...

Page 17: Operating Agents
If mineral oil, PFPE and DOT come into contact they will emulsify. That’s why the pumps must only be run with the type of lubricant specified for the pump. If you want to change the type of lubricant Oerlikon Leybold Vacuum should do the change. -
Page 18: Supplied Equipment
TRIVAC NT pumps with single-phase AC motor are supplied with switch, built-in thermal motor protection switch and plug for the mains cable. For TRIVAC NT pumps with three-phase AC motor, the switch, motor protec- tion switch, mains cable etc. are not included. 130002780_002_A0 - 12/2008 - © Oerlikon Leybold Vacuum... -

Page 26: Conforming Utilization
Regarding the suitability of the TRIVAC NT pumps for special appli- cations in which such gases, respectively substances shall be pumped, Oerlikon Leybold Vacuum should be consulted first. The pumps are not suited for pumping of liquids or media which carry large quantities of dust. - Page 27 Outside the pump due to motor, accessories Static electricity Possible, provided conducting parts of the pump are not connected to ground Chemical reactions Possible with the process liquid or the process gas 130002780_002_A0 - 12/2008 - © Oerlikon Leybold Vacuum...

Page 28: Connection To The System
The intake line must be clean. Deposits in the intake line may outgas and adversely affect the vacuum. The connecting flanges must be clean and undamaged. The maximum throughput of the pump is equivalent to the pumping speed of the pump, see technical data. 130002780_002_A0 - 12/2008 - © Oerlikon Leybold Vacuum... - Page 29 Never operate the pump with a sealed exhaust line. There is the danger of Warning injury. Before starting any work on the pump, the personnel must be informed about possible dangers first. All safety regulations must be observed. 130002780_002_A0 - 12/2008 - © Oerlikon Leybold Vacuum...
