4.2.3 Installing New Nitrogen Cylinder Assembly (PN 59531)
Tools required: 7/16" open end wrench
Phillips screwdriver
1-1/8" open end wrench
3/8" open end wrench
A/R 1/4"-wide Teflon tape (PN 60575)
A/R 1/2"-wide Teflon tape (PN 60911)
tube of fluorinated grease (PN 55593)
snoop, bottle of liquid gas leak detector (PN 64781)
1. Install the Teflon O-ring (PN 59217), fitting (PN 59287), and branch tee (PN 59750) on the new cylinder
and tighten until snug. Place a small amount of Krytox grease on both sides of Teflon O-ring prior to
installation. If installing new parts, Teflon tape is required.
2. If required, wrap two bands of 1" wide rubber friction tape (PN 58838) completely around the perimeter
of the cylinder; one at the cylinder bottom and the second at approximately 5.3" from the cylinder
bottom.
NOTE: Prior to wrapping tape, verify and mark on cylinder, center placement of tape, while holding cylinder in mounted
position on chassis.
3. Mount the cylinder in the chassis making sure that the tee fitting is correctly oriented to accept tubing
sections.
4. Install the two clamps (PN 58871) and four mounting screws (PN 14862).
5. Install the tubing sections, tightening all fitting nuts 1/4 turn from finger-tight using a 7/16" wrench.
6. Fill the cylinder to approximately 1000 PSIG and check all fittings for leaks. If there are no leaks fill
nitrogen supply cylinder to 2200 PSIG. See See Section 2.1 on page 3 for cylinder refilling procedure.
7. Install panel/chassis assembly in its enclosure as described in Section 4.2.1 on page 14.
4.2.4 ORION-2C Manifold Removal (PN 55283)
Tools required: Phillips screwdriver
11/32" wrench or nutdriver
.061" hex wrench
adjusting screwdriver (small flat blade)
11/32" open end wrench (thin)
7/16" open end wrench
NOTE: See Table 4-7 on page 32 and Figure 4-1 on page 33 for additional parts information.
1. Vent any remaining gas from the nitrogen cylinder to atmosphere. Disconnect the power cord from the
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 nitrogen cylinder and its associated tubing as outlined in Section 4.2.2 on page 15.
4. Remove the test port to ORION-2C tubing section using a 7/16" wrench.
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.
7. Using the 11/32" thin wrench, loosen and carefully remove the transducer from the ORION-2C
manifold.
8. Remove the tubing sections from the VENT and COARSE (pressure) inlet fittings on the ORION-2C,
using a 7/16" wrench
9. Remove the panel knobs from the COARSE (pressure), VERNIER and VENT valves using the .061" hex
wrench.
10. Loosen and remove the two panel screws (PN 60837) from the panel front that secure the manifold to the
panel.
11. Remove the four retaining nuts that secure the chassis to the panel.
12. Lift the chassis enough to allow the ORION-2C manifold to clear and remove the manifold.
