Allow at least 2 hours for the generator to cool prior to changing the catalyst module.
The
hydrocarbon catalyst module in the Parker Balston Nitrogen Generator is located behind the
upper service panel and should be changed approximately every three years (or when the
“Service System” LED starts blinking) to maintain the hydrocarbon removal specification for
the unit.

Maintenance
(Model UHPN2-1100 only)
Before servicing the Parker Balston Nitrogen Generator, isolate the unit from the com-
pressed air and electrical power supplies. Allow the generator to cool for at least 2 hours
before depressurizing (Model UHPN2-1100 only). All maintenance tasks for the Parker
Balston Nitrogen Generator should be performed by suitable personnel using reasonable
care.
The primary maintenance tasks required by the Parker Balston Nitrogen Generator are
changing the filter cartridges in the coalescing prefilter and particulate filters (annually), re-
placing the final membrane filter cartridge (annually), and replacing the hydrocarbon catalyst
module (Model UHPN2-1100 only, 3 years). A summary of the replacement part numbers and
recommended service frequency is shown at the end of this Maintenance section. See Figure
6 for the locations of the various maintenance items.
Additional coalescing prefilter cartridges, particulate filter cartridges, and membrane filter
cartridges for the Parker Balston HPN2-1100 and UHPN2-1100 Nitrogen Generators may
be ordered through your local representative. For convenience, a one-year supply of these
replacement cartridges has been assembled into a maintenance kit (MK7692 Maintenance Kit
for Model HPN2-1100 and MK7694 Maintenance Kit for Model UHPN2-1100).
If necessary, the Nitrogen Generator may be wiped clean with a dry cloth on an as needed
basis.
Do not use water, aerosols, or other cleaning agents to clean the unit. The use of any
liquid detergent to clean the generator could present an electrical hazard.
If the hydrocarbon catalyst module is not being replaced when the filters are replaced, there
is no need to allow the generator to cool. The only preparation needed to service the filters
is turning off the air supply to the generator and depressurizing the affected filter hous-
ings. To depressurize the filter housings, turn off the compressed air supply to the generator
and allow the generator to cycle until the inlet pressure displays zero. This should only take
10 minutes (1-2 generator cycles). Turn off power to generator.
The coalescing and particulate filters and the final membrane filter in the Nitrogen Generator
are easily accessible when the lower service panel is removed (see Figure 6). These filters
should be changed on an annual basis to maintain efficient operation of the system. The filter
cartridge in the coalescing prefilter assembly is removed by loosening the bowl from the filter
assembly, and unscrewing the element retainer from the base of the cartridge. Insert the
new filter cartridge (P/N 100-12-BX) and reassemble the housing in the reverse order.
The particulate filter(s) and final membrane filter cartridges are easily removed from the
housing by unscrewing the filter bowl from the filter head (no tools required). Insert the new
filter cartridge (P/N 050-05-BX or GS050-05-95) and reassemble the filter housing.
Replace the lower service panel after replacing the filter cartridges. The time required to
service all stages of filtration integral to the generator is approximately 30 minutes.
