set screws (23) with the .061" hex wrench.
6. Close the COARSE valve by turning the knob insert (4) clockwise until you feel the valve needle seat on
the O-ring (valve is now in the closed position).
7. Rotate gear (6) on the ISOLATION valve (inner valve), counter-clockwise until stopped, then rotate
clockwise 1/2 turn (opening isolation valves).
8. Use the PRESSURE LIMIT CONTROL (*1), to increase the supply pressure to between 80% and 100% of
full scale.
9. Open the VENT valve (*8) to atmosphere, zero the indicator (press ZERO switch [*12] less than 5
seconds), then close the VENT valve (*8).
10. Slowly open the COARSE valve by turning the knob insert (4) counter-clockwise until you notice the
displayed pressure increase. Then turn the knob insert slightly clockwise until the pressure stops rising.
11. Mark a radial line at the 12 o'clock position on the knob insert.
12. Turn the knob insert (4) clockwise to move the mark to the 6 o'clock position.
13. Turn the locknut (2) counter-clockwise until it contacts the bottom of the stop washer. Tighten the set
screw (34) on the locknut with the .050" hex wrench.
14. Re-check the unit to see if displayed pressure stops when the radial line is at the 12 o'clock position.
15. Install the COARSE valve knob (3) on the knob insert (4) and engage its gear (5) with the smaller
isolation valve gear (6). Turn the knob clockwise until the isolation valve is slightly snug.
Do not use excessive torque when adjusting valve. The seat can be damaged.
16. Remove the COARSE valve knob. Align the set screws (25) with the indentations on the knob insert
Install the knob on the insert while engaging the knob gear (5) with the isolation valve gear (6).
17. Tighten the set screws (25) with the .061" hex wrench. The COARSE valve is now adjusted.
18. To adjust the VENT valve, remove the ORION-2D VENT valve knob (3) using the .061" hex wrench
19. use a .050" hex wrench, to loosen the set screw (34) on the locknut (2) and turn the locknut clockwise to
its stop.
20. Check to see that the knob insert (4) is securely fastened to the valve shaft (11). If it is loose, tighten the
set screws (23) with the .061" hex wrench.
21. Close the COARSE valve by turning the COARSE knob (*2) clockwise.
22. Open the VENT valve (*8) to atmosphere, zero the indicator (press ZERO switch [*12] less than 5
seconds), then close the VENT valve knob insert (4) clockwise until slightly snug.
23. Use the PRESSURE LIMIT CONTROL (*1), to increase the supply pressure to between 80% and 100% of
full scale.
24. Open the COARSE valve until the indicated pressure stabilizes and then close the COARSE valve.
25. Slowly turn the VENT valve knob insert (4) counter-clockwise until the display starts to decrease, then
turn the knob insert (4) slightly until the indicated pressure stops decreasing.
26. Mark a radial line at the 12 o'clock position on the knob insert.
27. Turn the knob insert (4) clockwise to move the mark to the 6 o'clock position.
28. Turn the locknut (2) counter-clockwise until it contacts the bottom of the stop washer. Tighten the set
screw (34) on the locknut with the .050" hex wrench.
29. Re-check the unit to see if displayed pressure stops when the radial line is at the 12 o'clock position.
30. Align the set screws (25) with the indentations on the knob insert Install the VENT valve knob (3) on the
knob insert (4).
Do not use excessive torque when adjusting valve. The seat can be damaged.
31. Tighten the set screws (25) with the .061" hex wrench. The VENT valve is now adjusted.
