Ordering Information
Occasionally, one or both of the fuses in the UHP Nitrogen Generator may burn out. The fuse
located in the hydrocarbon removal module power harness is rated for 50 mA.
This is not a field-
serviceable fuse and should not be removed under any circumstances.
The main fuses are located
in the power receptacle on the side of the generator.
Before servicing the main fuses, turn the
generator off and disconnect the power cord from both the power supply and the generator power
receptacle.
To access the main fuses, use a small screwdriver to remove the fuse holder located in the power
receptacle of the generator. In the UHP Nitrogen Generator, both the phase and neutral are fused
separately. As a result of these configuration, both fuses should be checked any time fuse replace-
ment is warranted
. Replace either one or both fuses as necessary and re-assemble. To maintain
the safety and performance integrity of the product, use only fuses of the size and type detailed in
the specifications section of this bulletin.
This equipment has main fuses in both neutral and phase lines. Use care when servicing.

The tools required to change the catalyst module are: a Phillips head screwdriver, two 9/16"
wrenches (or adjustable wrenches), and one 1/2" wrench (or adjustable). The procedure for re-
placing the hydrocarbon catalyst module is as follows:
1
Turn off the inlet air supply to the generator. Wait approximately 10 minutes before turning
the generator power off. This will allow the generator to depressurize fully.
2
Unplug the generator from the power receptacle.
Allow the unit to cool for at least 2 hours
before removing the cover.
3
Remove the upper and lower service panels from the UHPN2-1100 (4 Phillips screws) and
disconnect the electrical fittings to the hydrocarbon catalyst module at the connectors (see
Figure 6).
4
Disconnect the two tubing connections to the hydrocarbon catalyst module (see Figure 6) us-
ing the wrenches (one as an anchor).
5
Remove the two screws which fasten the hydrocarbon catalyst module to the UHPN2-1100
frame.
6
Remove the spent module from the UHPN2-1100 and replace with the new module.
7
Re-connect the inlet and outlet fittings to the hydrocarbon catalyst module, open the supply
air valve, and check for leaks. Re-connect the module's electrical connections. Replace the
service panels. Plug the generator back into the wall receptacle.
8
Restart the UHPN2-1100 by switching the power on. The generator will begin its 5 hour
warm-up.
