4.2.12 Supply Pressure (PN 59730) and Pressure Limit Monitor (PN 59706) Gauges - Removal and Installation
Tools required: 7/16" wrench
9/16 " wrench
A/R 1/4" wide Teflon tape (PN 60575)
snoop, liquid leak gas detector (PN 64781)
Removal:
1. Vent any remaining nitrogen from cylinder to atmosphere. Disconnect power cord from 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 from the gauge, PN 59721, for Supply Pressure or PN 57684 for Pressure Limit Monitor.
6. Remove the two thumb-nuts, the mounting U-clamp, and the 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 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 maximum pressure. See Section 2.1 on page 4 for cylinder refilling
procedure.
6. Install panel/chassis assembly in its enclosure as described in Section 4.2.1 on page 14.
4.2.13 Test Port Quick-Connect Fitting (PN 59762) - Removal and Installation
If there is leakage out of the port, replace the test port quick-connect fitting.
Tools required: 5/8" two open end wrenches
7/16" open end wrench
A/R 1/4" wide Teflon tape (PN 60575)
A/R 1/2" wide Teflon tape (PN 60911)
snoop, liquid leak gas detector (PN 64781)
Removal:
1. Vent any remaining nitrogen from cylinder to atmosphere. Disconnect power cord from power source.
2. Remove front panel from its enclosure as described in Section 4.2.1 on page 14, and carefully set on a
bench top.
3. From rear of panel, remove the quick-connect tubing end nut and ferrules (note orientation) from test
port quick-connect fittng. Remove filter and place aside.
NOTE: Do not remove fittings attached to tubing.
4. Grasp the hex nut at the panel face with a 5/8" wrench and using a second wrench on the lock nut on rear
side of panel, turn the lock nut counter-clockwise. Slide quick-connect fitting out of panel from front.
Installation:
1. Remove the tubing end nut and ferrules (note orientation) from test port quick-connect fitting. Install the
quick-connect fitting thru front of panel. Thread and tighten lock nut, from rear of panel, on
quick-connect fittng.
2. Slide filter into fractional tube adapter fitting (PN 56223), attached to nylon tubing. Slide tubing end nut
and ferrules, in proper order, over fractional tube adapter fitting.
3. Slide fractional tube adapter fitting into quick-connect fitting from rear of panel. Thread and tighten
tubing end nut, on quick-connect fittng.
