Maintaining The Foreline Pump - Thermo Scientific TSQ 9000 Hardware Manual

Maintaining the Foreline Pump

Thermo Scientific
The foreline (roughing) pump is usually located on the floor behind the TSQ 9000
instrument and occasionally requires maintenance. It establishes the vacuum needed to run
the turbomolecular pump inside the 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 near the back of the
TSQ 9000 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 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.
