8. Attach the wire connecting the quadrupole entrance lens to the source interface board by
screwing in the terminal with a slotted screwdriver.
 To replace the analyzer tray
1. Put tray in manifold with transfer line out or pulled away.
a. If the gas tubes are attached to the transfer line, it will not pull as far away from the
path of the tray as would be best. Be extra careful not to scratch the end of
transferline with the tray, because that could cause a leak with the source plug later.
b. Do not screw in the analyzer tray until the transfer line is fully screwed in.
Note The analyzer tray will mount on one alignment pin in the back and the transfer line
on the right. The mixing chamber will rest on the transfer line when installed.
