Maintenance & Service 27
Turn the PUMP CONTROL switch (20) off when 1,000 PSI has been achieved. Check all fittings for
leaks. If there are no leaks vent system and remove pressure source.
7. Install panel/chassis assembly in its enclosure as described in Section 4.2.1 on page 16.
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. Using a pressure source connected to the INPUT PORT (4), turn the REGULATOR knob clockwise until
reaching between .5% to 1% of full scale, but not enough to disturb pressure relief valve.
NOTE: If pressure cannot be attained loosen locknut on shaft, rotate knob a few turns counter-clockwise, and
retighten locknut. If you hear the pressure relief valve open, 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 REGULATOR completely, by turning REGULATOR knob clockwise. If you reach between
10-11% 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 and Installation
• Regulated pressure gauge (PN 59745), 0–600 PSIG
• Regulated pressure gauge (PN 59751), 0–1,500 PSIG
• Accumulator gauge (PN 59749), 0–6,000 PSIG
• Accumulator gauge (PN 59696), 0–15,000 PSIG
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)
Panel Gauge Removal
1. Vent any remaining gas from the system 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 16, 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 tube connector
fitting from the gauge.
6. Remove the two thumb-nuts, the mounting U-clamp, and the gauge.
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)
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 onto the gauge.
4. Attach the tubing section that connects to the gauge fitting.
5. Using a pressure source connected to the INPUT PORT (4) set regulated pressure to 100 PSI. Enable the
PUMP CONTROL switch (20) and monitor the pressure as it builds in the ACCUMULATOR gauge (9).
Turn the PUMP CONTROL switch (20) off when 1,000 PSI has been achieved. Check all fittings for
leaks. If there are no leaks vent system and remove pressure source.
6. Install panel/chassis assembly in its enclosure as described in Section 4.2.1 on page 16.
