3.2.13 Panel Gage Removal
Tools required: Phillips screwdriver
7/16" wrench
9/16 " wrench
1. Vent any remaining gas from the nitrogen cylinder to atmosphere.
2. Remove front panel from its enclosure as described in Section 3.2.1 on page 5, and carefully place on a
bench top.
3. Disconnect the tubing section that connects to the gage fitting.
4. Loosen the two thumb-nuts that hold the gage mounting U-clamp.
5. While gripping the square portion of the gage port with the 9/16" wrench, remove the fitting from the
gage.
6. Remove the two thumb-nuts, the mounting U-clamp, and the gage.
3.2.14 Panel Gage Installation
Tools required: Phillips screwdriver
7/16" wrench
9/16 " wrench
A/R 1/4" wide Teflon tape (PN 60575)
bottle liquid leak gas detector (PN 64781)
1. Before installing a new gage, wrap two layers of new Teflon tape on the port.
2. To install the gage, reverse the order of steps 2 through 6 of the “Panel Gage Removal” procedure above.
3. Fill the cylinder to approximately 1000 PSIG and check all fittings for leaks. See Section 2.1 on page 3
for cylinder refilling procedure.
3.2.15 Port 1 & Port 2 Quick-Connect Fitting (PN 55426), Removal and Installation
There is relatively little maintenance that has to be done to the port fitting. Every 2 months, a little coating of
Silicone grease should be applied to the inner seal. 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 applicable testport.
Rotate fitting 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
2 3/4" wrenches
9/16 " wrench
A/R Teflon tape (PNs 60911 & 60575)
tube fluorinated grease (PN 55593)
bottle liquid leak gas detector (PN 64781)
1. Vent any remaining gas from the nitrogen cylinder to atmosphere.
2. Remove front panel from its enclosure as described in Section 3.2.1 on page 5, and carefully set on a
bench top.
3. Grasp the hex at the panel face with a 3/4" wrench and using a second wrench, turn the port fitting
counter-clockwise. The short nipple (PN 59112) may or may not be removed at the same time.
4. If the short nipple remains in the panel fitting, a new port can be installed on it. Remove any remnants of
sealing tape and wrap two turns of Teflon tape to the threads.
5. Install the new quick-connect fitting (PN 55426) by turning clockwise
6. If the nipple (PN 59112) is removed along with the old fitting, the nipple cannot be reused. Install a new
nipple along with the new port.
7. Fill the cylinder to approximately 1000 PSIG and check all fittings for leaks. See Section 2.1 on page 3
for cylinder refilling procedure.
