 To check the oil level of the foreline pump
1. Look in the oil-level sight-glass to see if the oil level is between the MIN and MAX marks.
2. If the oil level is below the MIN mark, add oil, as described in
Pump.
3. Look for oil that is clear or light amber in color.
a. If the oil is cloudy or discolored, purge the oil to decontaminate dissolved solvents, as
described in Purging Gas from the Oil in the Foreline
b. If the pump oil is still discolored, change it, as described in
Foreline Pump.
 To add oil to the foreline pump
Note If you are running samples, stop the acquisition before powering off the system.
1. Cool down the GC oven.
2. If you are using hydrogen as a carrier gas, cool down the injector to prepare the GC for
powering off. See the GC documentation for more information. After the heated zones
are cooled down, power-off the GC.
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 xvi de la préface pour plus d'informations.
