Startup
The Parker Balston UHP Nitrogen Generator requires five hours of warm-up time to achieve
rated purity.
Prior to shipment from the factory, the PSA towers are pressurized with high purity nitrogen
to prevent contamination from the atmosphere. The nitrogen is sealed into the towers by a
2-way valve directly upstream from the towers. Before starting the generator, remove the ser-
vice panel and open this 2-way valve (see Figure 5). Replace the service panel. There is also a
2-way (external) valve at the outlet of the generator. This valve must be closed at start-up and
remain closed until the 5 hour warm-up period is complete.
Open the inlet air supply valve (customer supplied) and turn the power switch (see Figure 1)
on the generator upward to the ON position. The “System Check” LED indicator will start
blinking once every 12 seconds. It will continue blinking during the warm-up period. The inlet
air pressure should be regulated to be between 60 psig and 125 psig (4.1 barg to 8.6 barg).
During the 5 hours of warm-up, there will be no flow of nitrogen from the generator.

Indicating Oxygen Trap -
If visible verification of the purity of the nitrogen stream is desirable,
install an indicating oxygen trap downstream from the Nitrogen Generator.
The Indicating
Oxygen Trap (P/N 72092)
is a trace oxygen scrubber which provides a visible indication of
nitrogen purity downstream from the generator. The indicating trap should be installed in an
easily visible location downstream from the Nitrogen Generator. Install the oxygen trap in a
vertical position to reduce channeling within the trap. The freshly installed indicating trap is
green. As long as a portion of the trap remains green, the trap is still removing trace oxygen
impurities. The trap gradually changes color from green to brown as it becomes saturated
with oxygen. Replace the trap when more than half of it has been consumed (turned brown).
Note: Bypass oxygen trap until nitrogen is at specified purity and lines are purged.
Hydrocarbon Scrubber -
The
Parker Balston 76080 Hydrocarbon Scrubber
is designed to
remove potentially damaging hydrocarbons and halogenated hydrocarbons from the com-
pressed air supply to the Parker Balston UHPN2-1100 UHP Nitrogen Generator.
