Maintaining the Foreline Pump
38 ISQ 7000 Hardware Manual
The foreline (roughing) pump is typically located on the floor behind the ISQ 7000 mass
spectrometer and occasionally requires maintenance. It establishes the vacuum needed to run
the turbomolecular pump inside the ISQ 7000 instrument. Typically, the foreline pump oil
needs to be replaced every four months. However, depending on your sample type and
frequency of use, your maintenance interval will be different. Refer to the foreline pump
documentation for information.
The foreline pump connects to the turbomolecular pump with a piece of 0.75 in. i.d. tubing.
The pump's power cable connects to the System Mech Pump connector on the back of the
ISQ 7000 instrument.
CAUTION INSTRUMENT DAMAGE: The foreline pump must be set to the line voltage
used at your location. Always plug the foreline pump power cable into the System Mech
Pump connector on the rear of the ISQ 7000 instrument and never into a wall outlet.
This prevents the foreline pump from operating when the instrument is powered off.
ATTENTION DOMMAGES À L'INSTRUMENT Ne pas poursuivre tant que l'instrument n'a
pas été ventilé, ou des morceaux de la colonne ou de la virole pourraient éclater dans
l'instrument. Pour vous assurer que l'instrument est ventilé, vérifiez dans quelle mesure le
couvercle en verre comprime le joint torique du couvercle supérieur dans le collecteur.
Lorsque la surface du joint torique en contact avec le verre équivaut à environ 1 mm, vous
pouvez sans danger ouvrir l'instrument et enlever la colonne.
