ATTENTION DOMMAGES À L'INSTRUMENT : utilisez uniquement de l'huile pour pompe
préliminaire approuvée par le fabricant, afin d'éviter d'endommager l'instrument ou de
provoquer un incendie.
11. If the oil level goes above the MAX level mark, remove the drain plug and drain the excess
oil into a suitable container.
12. Reattach the oil filler plug.
13. Twist the vent valve one and a half times in a clockwise direction.
14. Close the front door of the instrument.
15. Reconnect the foreline pump power cable to the System Mech Pump connector on the
back of the instrument.
16. Reconnect the optional mechanical pump to the instrument.
17. Power-on the TSQ 9000 system.
18. Purge the foreline pump for 10 minutes using the gas ballast to remove excess gases from
the new oil.
Purging (or decontaminating) the oil in the foreline pump removes dissolved gases and
low-boiling-point liquids from the oil. Purge the oil if it is cloudy or discolored. You can
purge the oil without interrupting system operation.
Set the gas-ballast control to the closed position (0 means closed) to purge the oil..
CAUTION INSTRUMENT DAMAGE: While the gas is being purged, more oil vapor is
being generated. If you leave the purge open for an excessive amount of time, the pump
oil will become mist, which could damage the pump. Never purge your pump for more
than 10 minutes at a time.
ATTENTION DOMMAGES À L'INSTRUMENT : lorsque le gaz est en train d'être purgé, cela
génère davantage de vapeur d'huile. Si vous laissez la purge ouverte pendant trop longtemps,
l'huile de la pompe sera transformée en brouillard, ce qui peut endommager la pompe. Ne
purgez jamais votre pompe pendant plus de 10 minutes à la fois.
