Maintaining the MMI 8
Maintaining Your GC 141
To Change the Liner and O-Ring on the MMI
1 Gather the following:
• Replacement O- ring (See “Consumables and Parts for
the MMI” on page 128.)
• Replacement liner
• Tweezers
• Wrench, hex for changing septum
• Lint- free gloves
2 Load the inlet maintenance method and wait for the GC
to become ready.
3 Slide the locking tab forward (counterclockwise). Lift the
septum assembly straight up and away from the inlet to
avoid chipping or breaking the liner.
4 Loosen the O- ring from the sealing surface with tweezers.
Be careful! The oven and/or inlet may be hot enough to cause
burns. If either is hot, wear heat-resistant gloves to protect your
hands.
