To reinstall the API source interface
1. Orient the API source interface with the release latch at the top (Figure 42).
2. Carefully insert the API source interface into the vacuum manifold.
3. Reinstall the API source housing.
4. Start up the system as described in “Starting the System after a Complete Shutdown” on
page 53.
Maintaining the Forepump
Maintaining the forepumps requires inspecting, adding, purging, and changing the pump oil.
Refer to the manufacturer’s manual for instructions.
Check the forepump oil often. New oil has a translucent light amber color. During normal
operation, oil must always be visible in the oil level sight glass between the MIN and MAX
marks. If the oil level is below the MIN mark, add oil. If the oil is cloudy or discolored, purge
the oil to decontaminate dissolved solvents. If the pump oil is still discolored, change it. Plan
to change the pump oil every 10 000 hours (or about every 12–13 months) of operation.
To access the forepumps under the workbench
1. Place the mass spectrometer in Off mode.
2. Place the electronics service switch in the Service Mode (down) position.
3. Turn off the Main Power switch.
4. Lift up the workbench’s front panel to remove it, and set it aside.
5. Carefully move the forepumps forward.
6. Reattach the front panel when you are ready.
CAUTION To minimize the risk of oil contamination in the vacuum system, make sure
that the purging ballast is closed when you vent the system to atmosphere.
CAUTION Possible pinch points. Be aware where you place your hands when you
remove or attach the workbench’s front panel.
