Maintenance and Service 43
6. Clean both the needle (11) and housing (10) in solvent, dry the parts and apply a small amount of
fluorinated Krytox grease to the needle threads before reassembly.
7. Assemble the Valve Needle (11) into the Valve Needle Housing (10) and turn it until it stops.
8. Reinstall the needle/housing assembly into the valve cavity until finger tight.
9. Mount the manifold body (16) in a vise. For the Coarse (pressure) and Vent valves only, torque the
needle/housing assembly to 325 in-lb. using the needle housing socket (PN 65580) and torque wrench.
10. Install the housing lock nuts (1) onto the housing (10) and tighten until snug with the 3/4" socket.
11. Using the .050" hex wrench, install and tighten the lock nut (2) and set screw (34).
12. Install the Knob Insert (4) over the Valve Needle (11) shaft, align the Set Screws (23) with the indents
and tighten with the .061" hex wrench.
13. For the isolation valves (two inner valves), install the Needle Housing (19) and tighten until snug using
the Isolation Valve Housing Installation Socket (PN 59793), Female Socket (PN 65581) and torque
wrench.
NOTE: There is no specified torque, so use care when tightening so as not to break the socket nibs.
14. Install the Gear (6) over the Isolation Valve Needle (18) shaft, align the Set Screws (23) with the indents
and tighten with the .061" hex wrench.
15. Apply a small amount of fluorinated Krytox grease to the threads of the isolation valve needles (18) and
install into the valve by turning counter-clockwise. Rotate the gear until the needle just stops at the seat.
7.2.7 ORION Manifold - Panel Installation
Tools required: 7/16" open end wrench
Phillips screwdriver
hex wrench (.061")
SNOOP, liquid leak gas detector (PN 64781)
11/32" open end wrench (thin)
1. If not already done, remove the panel knobs from the Input (pressure), Vernier and Vent valves using the
.061" hex wrench.
2. Install the manifold with the transducer port side facing the panel bottom. Install the two mounting
screws (PN 60837) from the panel front and tighten until snug.
3. Install the Vernier Knob (17) onto the Vernier Valve Shaft (14). Align the set screws (25) with the
indentations on the Vernier Valve Shaft and tighten until snug using the .061" hex wrench.
4. To install and adjust the Input (pressure) and Vent Valve Knobs, follow the procedure in Section 7.2.8.
5. Install the transducer into the manifold port, tighten with the 11/32" thin wrench and reconnect its wire
connector.
NOTE: If transducer is hard-wired, connect the 4 wires to the terminal block, TB1, on the CPU board per the
following:
6. Install all tubing sections that attach to the ORION Manifold.
7. Install cover as described in Section 7.2.1 on page 39.
