If there is leakage out of the port when the pressure cap is in place, replace the port fitting.
Tools required: Phillips screwdriver
3/4" two open end wrenches
9/16" open end wrench
A/R 1/4" wide Teflon tape (PN 60575)
A/R 1/2" wide Teflon tape (PN 60911)
tube fluorinated Krytox grease (PN 55593)
snoop, liquid leak gas detector (PN 64781)
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 set on a
bench top.
3. Grasp the hex adapter (PN 58062) at the panel face with a 3/4" wrench and using a second wrench, turn
the test port quick-connect fitting (PN 55426) 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. If there are no leaks fill
nitrogen supply cylinder to 2200 PSIG. See Section 2.1 on page 3 for cylinder refilling procedure.
8. Install panel/chassis assembly in its enclosure as described in Section 4.2.1 on page 14.

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. Loosen and remove the tubing end nut from the reducing union (PN 59764).

5. Clean the filter (PN 54188) in solvent (de-natured alcohol) and blow-dry with compressed air.
Test Port Filter Installation
1. To reinstall, reverse the order of Steps 2 and 3 of the test port filter removal procedure above.
2. 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.
3. Install panel/chassis assembly in its enclosure as described in Section 4.2.1 on page 14.
