1. Remove cover from its chassis as described in Section 4.2.1 on page 28, and carefully set on a bench top.
2. Loosen and remove the tubing end nut from the test port fitting.
3. Grasp the hex nut at the panel face with a 5/8" wrench and using a second wrench, turn the nut on inside
of panel counter-clockwise.
4. Install the new quick-connect fitting (PN 59762) by reversing steps.
5. Using a pressure source set input pressure to approximately 100% of full scale rating of UPS3110 and
check all fittings for leaks.

4.2.17 Test Port Quick-Connect Fitting (PN 55426), Removal and Installation - 500, 1000 and 2000 Full Scale PSI
Models UPS3110[]B[], UPS3110[]C[] and UPS3110[]F[] only.
There is relatively little maintenance that has to be done to the port fitting. Every 2 months, a little coating of
Krytox 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
test port. 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
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. Remove front cover from its enclosure as described in Section 4.2.1 on page 28, and carefully set on a
bench top.
2. 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.
3. 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.
NOTE: 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 quick connecting fitting.
4. Install the new quick-connect fitting (PN 55426) by turning clockwise.
5. Using a pressure source set input pressure to approximately 100% of full scale rating of UPS3110 and
check all fittings for leaks.
6. Install cover on its enclosure as described in Section 4.2.1 on page 28.
