110 5975/5977 Series MSD Operating Manual
8 Plug the MSD power cord in.
9 Switch the MSD on to establish a rough vacuum. Verify that the turbo pump
speed is greater than 50%, or that the foreline pressure is 1 Torr.
10 Switch the MSD off.
11 Close the analyzer cover.
12 Disconnect the LAN, remote, and power cables.
The MSD can now be stored or moved. The foreline pump cannot be
disconnected; it must be moved with the MSD. Make sure the MSD remains
upright and is never tipped on its side or inverted.
Do not overtighten the side plate thumbscrews. Overtightening will strip the
threads in the analyzer chamber. It will also warp the side plate and cause
leaks.
The MSD must remain upright at all times. If you need to ship your MSD to
another location, contact your Agilent Technologies service representative for
advice about packing and shipping.
