4. The pneumatics block is on the rear face of the manifold. If you do not
intend to remove the manifold, remove the screw holding the pneumatics
block. Remove the T-20 screw on the front only if you intend to remove
the manifold.
5. Unlock the detector manifold ribbon cable from the EPC board and detach
the connector. The adjacent ribbon cable may have to be removed as well.

detector’s interface board on the right side of the instrument.
