1. Vent any remaining nitrogen from cylinder to atmosphere. Disconnect power cord from power source.
2. Remove front panel from its enclosure as described in Section 4.2.1 on page 14, and place unit on a
bench top.
3. Remove the tubing section from the VENT outlet fitting on the ORION-2D, using a 7/16" wrench
4. Remove the flexible tubing going to the transducer port. Also the flexible tubing coming from the
vacuum generator, compressed air port, and the mode select assembly.
NOTE: Marking flexible tubing ends may be helpful for reinstalling ORION-2D.
5. If the transducer is wired via a connector, remove the connector by turning counter-clockwise. If the
transducer is hard-wired, loosen and remove the four transducer wires (red, white, green, black) from the
terminal block, TB1, on the CPU board, using the small flat-blade screwdriver.
6. Break the wire ties that hold the transducer wires so that the wires are free.

manifold.
8. Remove the panel knobs from the COARSE (pressure), VERNIER and VENT valves using the .061" hex
wrench.
NOTE: Earlier manufactured units may have the vacuum generator mounted to the ORION-2D manifold body. If so,
remove the muffler, coupling and long nipple assembly from the vacuum generator.
9. While holding ORION-2D, loosen and remove the two panel screws (PN 60837) from the panel front
that secure the manifold to the panel. Remove the ORION-2D.
