b. Choose Pump from the shortcut menu.
c. Wait for the Surveyor MSQ Plus MS detector to reach high vacuum. The server light
will change from flashing amber to solid amber. Reaching high vacuum takes
approximately 10 minutes.
The vacuum system consists of two types of vacuum pumps, a turbomolecular pump and a
forepump. The turbomolecular pump is housed within the Surveyor MSQ Plus MS detector
and requires a trained service engineer for servicing. The forepump (also referred to as a
backing pump, a rotary pump, or a roughing pump) is external to the Surveyor MSQ Plus MS
detector and requires routine maintenance for optimal performance.
Note You can find more information on operating and maintaining the rotary pump in
the manual that is shipped with the pump.
Check both the level and the color of the oil in the forepump at least once a month.
Check the oil by looking through the oil sight level window of the forepump. See
The oil level should be between the upper and lower marks positioned next to the window.
The oil color should be a clear straw color.
• If the oil level is near or below the lower mark, add more oil as described in the manual
that comes with the Edwards forepump.
• If the oil has turned red in color or if the pump has been in operation for more than
3000 hours since the oil was replaced, replace the oil as described in the manual that
comes with the Edwards forepump.
Purge the oil on a regular basis as described in
Pump Oil" on page 48.
