6. Close the manifold door and slightly tighten the vent valve knob by turning it one half
turn clockwise.
7. Flip the power switch on the back of the TSQ 9000 instrument upwards to power on the
instrument. This will help you achieve good vacuum.
8. Center the manifold door so that the screw holes are aligned with the manifold. And
insert the four manifold screws, tightening each finger-tight such that the o-ring is
engaged on every surface.
9. Tighten the four manifold screws using a T20 Torxhead screwdriver.
10. Tighten the vent valve knob completely by turning it approximately one turn clockwise.
11. Close the front door of the instrument.
12. Restart the system as in “Powering On the TSQ 9000 System” on page 7 .
Tip At this point, you may want to remove the top cover and look at the position of the
ion source cartridge through the manifold cover. There should be a small gap between the
RF Lens insulator and the inside end of the sleeve. This helps to prevent thermal
expansion of the sleeve from moving the optics.
