6. Install panel/chassis assembly in its enclosure as described in Section 3.2.1 on page 6.
3.2.12 Panel Gauge Removal and Installation
• Regulated pressure gauge (PN 59751), 0–1,500 PSIG
• Accumulator or Output pressure 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 3.2.1 on page 6, 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
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 REGULATOR (10) pressure to 100 PSI.
Enable the POWER switch (2) and monitor the pressure as it builds in the ACCUMULATOR
PRESSURE gauge (7). Turn the POWER switch (2) off when 1,000 PSI has been achieved. Check all
fittings for leaks. If there are no leaks vent system and remove pressure source.
NOTE: See Figure 2-1 on page 5 for items in parenthesis.
6. Install panel/chassis assembly in its enclosure as described in Section 3.2.1 on page 6.
3.2.13 Test Port Quick-Connect Fitting (PN 59004) and Filter (PN 54188), Removal and Installation
Every two months, a coating of fluorinated Krytox grease should be applied to the inner seal of the test port
fitting. The pressure cap (PN 58216) 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 pressure cap. Do not put grease on flat end of tip, as this may allow grease to enter system. Vent unit line
pressure to atmosphere. Plug pressure cap into test port. Rotate pressure cap clockwise and counter-clockwise to
transfer fluorinated Krytox grease to O-ring seal.
If there is leakage out of the port when the pressure cap is in place, replace the port fitting.
Tools required: Phillips screwdriver
11/16" Open end wrench
Adjustable wrench
9/16" Open end wrench
A/R solvent (de-natured alcohol)
A/R 1/4" wide Teflon tape (PN 60575)

Tube fluorinated grease (PN 55593)
Snoop, liquid leak gas detector (PN 64781)
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 3.2.1 on page 6, and carefully set on a
bench top.
