Replacing The Inlet Epc Flow Manifold - Agilent Technologies 6890 Series Service Manual

Replacing the inlet EPC flow manifold

WARNING Before proceeding, cool the heated zones, then turn off the main power switch.
Set pressure/flow to 0.0. Follow ESD precautions.
All EPC inlets (and the ECD detector) in the 6890 GC use Type 1 flow
manifolds.
1. Shut off the main gas supply to the manifold and remove the 1/8-inch
Swagelok fitting for the gas supply.
2. Remove the plastic detector cover and the plastic pneumatics cover.
3. Remove the metal RFI shield and the rear top cover on the back of the GC.
4. Disconnect the ribbon cable for the module from the main EPC board.
The adjacent ribbon cable may have to be disconnected as well.
