CAUTION! Leave the roughing pump running for a minimum of 15 minutes
after turning off the instrument's main power switch. When the main power
switch is turned off, the turbo pumps continue to rotate without power for a
few minutes and continue to provide vacuum to the vacuum chamber. If, during
this time, the roughing pump is turned off, the pressure in the vacuum line
between the roughing pump and the turbo pumps increases. The increase in
back pressure can create an incorrect load on the turbo pumps' bearings and
can cause a catastrophic failure of the turbo pumps.
CAUTION! If the instrument is to be shut down for any length of time, we
recommend that the vacuum chamber be vented to prevent exhaust from the
roughing pump being sucked back into the vacuum chamber. To vent the
vacuum chamber, follow steps 5 to 7.
