4 If necessary, slide the foreline pump out from under the vacuum manifold.
The foreline pump may be located on the floor, on the lab bench next to or behind
the MSD, or under the vacuum manifold at the back of the MSD.
5 Move the MSD away from the GC until you have access to the GC/MSD
interface cable.
6 Disconnect the GC/MSD interface cable.
Disconnecting the cable with the GC on can cause a fault condition.
