2.
Determine if the oil level is between the Max Oil Level and Min Oil Level
marks next to the window.
•
If the oil level is closer to the Min Oil Level mark, add oil. Use Edwards
45 oil (Part No. 09923492, 1 liter).
•
If it is near the scheduled six-month service, drain and refill the pump
with clean oil.
•
If the oil is contaminated (indicated by a darkened color), try gas ballasting
and if that does not help, drain and refill the pump with clean oil.
Adding Oil to the Forepump Reservoir
CAUTION
ATTENTION
Vent the mass spectrometer before opening the plug to add oil.
Évacuer le spectromètre de masse avant d'ouvrir le bouchon pour
ajouter de l'huile.
1.
Unscrew and remove one of the filler plugs on the top of the pump.
2.
Locate the bottle of pump oil supplied with the pump and add oil until it
reaches the MAX mark on the top of the oil level indicator. Do not overfill.
3.
Replace the oil filler plug by tightening it until it is fingertight. Do not
overtighten the oil filler plug.
4.
After restarting the pump and allowing it to run for a few minutes, recheck the
oil level. If the oil level is below the MAX mark, repeat the above procedure by
adding more oil until it reaches the MAX mark.
Decontaminating the Oil
The pump oil should be clear. If the oil is cloudy or discolored, it is contaminated with
residual sample vapors.
1.
Observe the oil in the oil level indicator.
2.
Turn the mode selector fully counterclockwise to select the High Throughput
mode and set the gas ballast control to the low flow (position I).
