When performing routine maintenance, carefully follow the instructions provided in this
section to avoid injury or damage. Service should be performed by persons familiar with
the service and safety requirements of electromechanical / electrochemical devices.
The primary maintenance tasks required by the Parker Balston FID 1000 and FID 2500 are:
changing the prefilter cartridge (annually), changing the sintered metal filter assembly (annually),
and replacing the catalyst module (2 years). Each of these components are readily accessible
by removing the side panel of the generator. A summary of the replacement part numbers and
recommended Service frequency is shown at the end of the Maintenance section. See Figure 13
for the locations of the prefilter, final filter, and catalyst module.
Additional coalescing prefilter cartridges and final filter cartridges for the Parker Balston FID 1000
and FID 2500 Gas Stations may be ordered through your local representative. For convenience,
the replacement prefilter cartridge, final sintered metal filter, desiccant cartridge and DI resin
cartridge have been assembled into a maintenance kit (P/N MKFID1000). With proper care and
maintenance, the FID 1000 and FID 2500 / hydrogen generators will provide years of trouble free
operation. No adjustments or calibrations need to be made to the generator. Only routine service
is needed to maintain peak operational conditions.
Before Servicing the Parker Balston FID1000 or 2500 Gas Station, isolate the unit from the
compressed air and electrical supplies, the hydrogen output, depressurize the prefilter and
turn the unit Off.
The only tool required to change the prefilter cartridge is a Phillips head screwdriver. Use the
screwdriver to remove the generator side cover. The Grade BX prefilter will be accessible from
the side of the generator, after the generator cover is removed. The filter cartridge inside the
housing should be changed on an annual basis to maintain efficient operation of the system.
Remove the filter cartridge housed in this filter assembly by unscrewing the filter bowl from the
filter head and unscrewing the element retainer disc from the tie rod. Insert the new filter cartridge
(P/N 050-05-BX) and re-assemble the filter housing in reverse order.

Maintenance
•
Switch power off to unit and unplug generator from power. Allow the compressed air to
continue to flow through the unit to improve heat dissipation during cooling. Allow the
generator to cool for at least 2 hours.
•
Close the (customer installed) inlet air valve.
•
Remove Main chassis cover. There are 2 screws on the left side and 2 under the hinged
cover of the generator (figure 13).
•
Remove Right-side cover. There are 4 screws on the right side of the unit. (figure 13).
•
Disconnect Catalyst Module connector located on right side of the unit (figure 13 and 14).
•
Disconnect solenoid valve connector (figure 15).
•
Locate main connector (figure 13). Using Wago tool, included in replacement module kit,
insert tool into main connector as shown in figure 16. Depress tool and remove yellow wire
from position 7 of main connector. Similarly remove brown wire from position 8.
•
Remove connections to inlet and outlet air ports at the rear of the generator (figure 17).
•
Remove 3 fasteners holding the catalyst assembly module at the rear of the generator – See
figure 17 for FID 2500 or figure 187 for FID 1000.
•
Slowly remove Module from generator.
•
Replace with new assembly- which includes a new zero air filter, final filter, catalyst module,
and solenoid valve.
•
Reverse above procedure – reassemble module into chassis, reconnect air lines, re-attach
electrical connectors and insert red and yellow thermocouple wires as shown previously.
•
Pressurize the system and check for leaks in the air lines and fittings.
•
Re-assemble covers to unit and supply power.
