Operation
4.1
Start-up
Each time before starting up check the oil level.
On initial start-up, after prolonged idle periods or after an oil change, the
specified ultimate pressure cannot be attained until the oil is degassed. This
can be done by running the pump for approx. 30 min. with the intake line
closed and the gas ballast valve (7/5) open.
Before starting the pump ensure that the pump and the fitted accesso-
ries meet the requirements of your application and that safe operation
can be guaranteed.
Avoid exposure of any part of the body to the vacuum. There is the dan-
ger of injury. Never operate the pump with an open intake port. Vacuum
connections as well as oil-fill and oil-drain openings must never be ope-
ned during operation.
The safety regulations which apply to the application in each case must
be observed. This applies to installation, operation and during mainten-
ance (service) as well as waste disposal and transportation.
4.2
Operation
TRIVAC B pumps can pump condensable gases and vapours, provided
that the gas ballast valve (7/5) is open and the pump has attained its
operating temperature.
4.2.1
Pumping of Non-Condensable Gases
and Vapours
If the process contains mainly permanent gases, the TRIVAC B may be
operated without gas ballast (position 0), provided that the saturation
vapour pressure at operating temperature is not exceeded during com-
pression.
If the composition of the gases to be pumped is not known and if conden-
sation in the pump cannot be ruled out, run the pump with the gas ballast
valve open in accordance with Section 4.2.2.
