Changing The Oil In A Foreline Pump - Thermo Scientific TSQ 9000 Hardware Manual

Changing the Oil in a Foreline Pump

Thermo Scientific
You should change the foreline pump oil every four months or after 3,000 hours of operation.
If you use ammonia as a chemical ionization reagent gas, change the oil every month.
Ammonia is highly corrosive and quickly damages the seals in the foreline pump.
Note For best results, change the oil while the foreline pump is still warm. Be careful, as
the oil can be very hot if the pump has been used recently.
To change the oil in the foreline pump:.
Note If you are running samples, stop the acquisition before powering off the system.
CAUTION BURN HAZARD: The oven may be hot. Allow it to cool to room temperature
before opening it. The injector will still be hot, so do not touch it.
ATTENTION RISQUE DE BRÛLURE : le four peut être chaud. Laissez-le refroidir à la
température ambiante avant de l'ouvrir. L'injecteur sera toujours chaud, donc ne le touchez
pas.
WARNING FIRE HAZARD: If you are using hydrogen as a carrier gas, you must cool down
and shut off the GC to prevent the buildup of hydrogen in the vacuum manifold. See the
"Hydrogen Safety Precautions"
AVERTISSEMENT RISQUE D'INCENDIE : si vous utilisez de l'hydrogène comme gaz
vecteur, vous devez refroidir et mettre hors tension le CG pour éviter l'accumulation
d'hydrogène dans le collecteur à vide. Reportez-vous aux « Précautions de sécurité relatives à
l'hydrogène » à la page xix de la préface pour plus d'informations.
1. Click the Shut Down button on the TSQ 9000 Dashboard.
2. Click the Yes button to continue the shutdown process.The heaters and turbomolecular
pump power off. Once the turbomolecular pump reaches 50% rpm, the foreline pump
powers off, and you may vent the system. At this point, the vacuum light blinks orange
rapidly, and the system is ready to shut down.
3. Reach over to the left side of the instrument and push down on the power switch to
power-off the TSQ 9000 system.
