Maintenance of the Nitrogen
Generator
The nitrogen generator cabinet con-
tains three separate cartridge filters.
It is recommended that each of the
filter cartridges be replaced as part of
an annual preventative maintenance
program. In some environments it may
be necessary to replace filters more
frequently. When maintained properly
the nitrogen separation membrane will
provide up to 20 years of service life.
Filter Replacement Procedure
With reference to Figure 4, perform
the following steps when replacing the
cartridge filters located in the Filter
Housing.
Step 1.
Turn the power supply to the
unit off.
Step 2.
Close the Inlet and Outlet Ball
Valves, and open the Bypass Ball Valve.
Step 3.
Depressurize the nitrogen gen-
erator internal inlet piping by slowly
opening the Depressurization Ball
Valve in the cabinet to the left of the
filter housing.
Step 4.
Remove the filter housing by
pulling down on the blue housing lock
and turning the filter housing count-
er-clock wise.
Step 5.
Once the filter housing has
been removed, the filter cartridge
inside is removed by first unscrewing
the black retaining disc at the base of
the cartridge and then pulling down on
the cartridge. Discard the old filter car-
tridge and replace it with the appropri-
ately marked filter cartridge from the
filter replacement kit by pushing up
so that it fits snugly onto the receiving
cylinder in the upper part of the filter
housing. Hand tighten the black retain-
ing disc back onto the central metal
threaded rod.
Step 6.
Replace the filter housing by
pushing up into position and turning the
housing clockwise until blue housing
lock locks into place.
Step 7.
Repeat Step 4 through Step 6
for each additional filter.
Note:
Filters 2 & 3 do not have a black retain-
ing disc, filters screw directly into housing.
