7. Install panel/chassis assembly in its enclosure as described in Section 4.2.1 on page 14.
8. Energize the unit and let warm up. Turn RANGE SELECT switch to highest range.
9. Close the COARSE valve by turning the COARSE knob clockwise.
10. Turn the regulator knob clockwise until reaching between 5-10% of full scale, but not enough to disturb
pressure relief valve.
NOTE: If pressure can not be attained loosen locknut on shaft, rotate knob a few turns counter-clockwise, re-tighten
locknut. If you hear the pressure relief valve then rotate regulator knob counter-clockwise until relief valve shuts off.
11. Remove locknut from threaded shaft, and rotate knob counter-clockwise until bottoming out on large
locknut. After touching large locknut rotate knob clockwise 1/8 turn. Hold knob in position, install and
tighten the locknut with 40 - 50 in. lbs. of torque using a 1/2" socket.
12. Open pressure limit monitor completely, by turning regulator knob clockwise. If you reach between
100-105% of full scale and pressure relief valve was not disturbed, regulator has been adjusted properly.
13. Replace regulator knob cap.
4.2.15 Panel Gauge Removal
Tools required: Phillips screwdriver
7/16" wrench
9/16 " wrench
NOTE: Call CONDEC for replacement part numbers.
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 carefully place on a
bench top.
3. Disconnect the tubing section that connects to the gauge fitting.
4. Loosen the two thumb-nuts that hold the gauge mounting U-clamp.
5. While gripping the square portion of the gauge port with the 9/16" wrench, remove the female tube
connector (PN 59721) from the gauge.
6. Remove the two thumb-nuts, the mounting U-clamp, and the gauge.
4.2.16 Panel Gauge Installation
Tools required: Phillips screwdriver
7/16" wrench
9/16" wrench
A/R 1/4" wide Teflon tape (PN 60575)
snoop, liquid leak gas detector (PN 64781)
NOTE: Call CONDEC for replacement part numbers.
1. Before installing a new gauge, wrap two layers of new Teflon tape on the port.
2. Install gauge into panel, secure with U-clamp and tighten the two thumb screws.
3. While gripping the square portion of the gauge port with the 9/16" wrench, tighten the female tube
connector on to the gauge.
4. Attach the tubing section that connects to the gauge fitting.
5. 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 Section 2.1 on page 3 for cylinder refilling procedure.
6. Install panel/chassis assembly in its enclosure as described in Section 4.2.1 on page 14.
4.2.17 Test Port Quick-Connect Fitting (PN 55426), Removal and Installation
Every two months, a coating of Krytox grease should be applied to the inner seal of the test port fitting. The
pressure cap (PN 55434) should be plugged in whenever the unit is not in use.
NOTE: For simplest method, apply fluorinated Krytox grease to the outside surface between sealing lip and end of
mating quick-disconnect fitting. Vent unit line pressure to atmosphere. Plug quick-connect fitting into test port. Rotate
fitting clockwise and counter-clockwise to transfer fluorinated Krytox grease to O-ring seal.
