GENERATION NITROGEN GENERATOR SYSTEM MANUAL
MAINTENANCE (continued)
COALESCING & PARTICLE FILTER ASSEMBLIES — REPLACE BI-ANNUALLY OR EVERY 400 HOURS
(continued)
3) Carefully unscrew the filter housings (retain housing O-rings for reuse) from the bodies.
4) If necessary, clean the filter housings with soap and warm water.
5) Replace coalescing and particle filters and O-rings.
6) Tighten housings securely but do not over-tighten.
7) Release pressure from nitrogen storage tank using the sump valve (see figure 11 on page 19) until
95 psi remains.
8) Reconnect power and verify that the compressor successfully charges the storage tank — this process
should take approx. 10 minutes.
CLIMATE CONTROL FILTER — REPLACE BI-ANNUALLY
Install a new filter, Part No. 1030-1302:
1) Replacement of the climate control filter is dependent of outside conditions such as dust or other debris.
2) Slide the climate control filter from the retaining brackets. Some units may require removal of the
brackets.
3) Replace filter.
OTHER MAINTENANCE
STORAGE TANK PRESSURE SWITCH
The pressure switch setting is factory set and normally should not change. If problems are encountered
during shipment or maintenance activity, the following procedure is for reference:
1) Disconnect power to the generator.
2) Remove pressure switch cover.
3) Loosen the lock nut with 3/4" open end wrench.
4) Using a 5/8" open-end wrench, turn the adjuster clockwise to increase the set point and
counterclockwise to decrease the set point.
5) Hold the adjuster with wrench and tighten lock nut.
6) If deadband adjustment is required, turn thumbwheel clockwise to increase deadband and
counterclockwise to decrease deadband.
7) Reinstall cover and reconnect power to generator to check adjustments.
DOOR GASKET
Inspect door gasket bi-annually for rips, tears or misalignment.
ADJUSTING THE PURITY
The purity of the nitrogen is factory preset. The purity of the nitrogen gas can be set between 97% and
99.5%.
IMPORTANT: Adjusting the purity is a procedure that requires a skillful technician with knowledge
of the process. If this procedure is to be done, we require service by SPX Transformer Solutions to
prevent voiding warranty.
