Pumping the MS Down
Make sure that the data system is running before starting the MS. The MS does not operate
until it receives instructions from the data system.
1. Ensure that the Main Power switch is off and that the electronics service switch is in the
Service Mode position.
2. Plug in the power cord for the MS.
3. Turn on the Main Power switch.
This turns on the forepump or forepumps and the turbomolecular pumps. All LEDs on
the front panel are off.
4. Wait 15 minutes before you place the electronics service switch in the Operating Mode
(up) position.
5. Wait at least 15 hours for the pumps to create sufficient vacuum.
