Two coalescing prefilters and one activated carbon scrubber are incorporated into the Parker
Balston Nitrogen Generator to protect the membrane module from contamination. These filters
are located behind the filtration access panel. The coalescing filters remove liquids and particu-
late matter from the incoming air supply and are equipped with float drains which automatically
drain any liquids which accumulate inside the filter housing. The drains are connected to 1/4”
O.D. plastic tubing which discharges to atmosphere at the back of the nitrogen generator (see
Figure 1). The activated carbon filter removes hydrocarbons which may be detrimental to the
membrane fibers.
Air separation takes place in the membrane module. The module consists of bundles of hollow
fiber membranes. As the air passes through these hollow fibers, oxygen and water molecules
pass through the membrane wall at a higher rate than nitrogen molecules. This results in a high
purity, dry nitrogen gas stream exiting the membrane module. The oxygen enriched permeate
stream exits the membrane module through ports on the side of the module at a very low pres-
sure.
The final filter is a .01 micron (absolute) membrane filter. The final membrane filter will assure the
user a clean, commercially sterile supply of high purity nitrogen.
The controls in the Parker Balston Nitrogen Generator consist of an operating pressure gauge,
a flowmeter and flow control valve, and an outlet pressure regulator and gauge (see Figure 1).
Proper use of these controls will assure the user of a 95% to 99.5% nitrogen outlet stream,
depending on operating pressure and flow rate. The pressure gauges, which are mounted on
the front panel, measure operating pressure and outlet pressure. The flowmeter measures the
flow rate of nitrogen exiting the membrane module. The scale on this flowmeter is dimensionless
because the operating pressure can range from 60 psig to 145 psig (4 barg to 10 barg). The
Nitrogen Purity Label on the control panel is used to convert the dimensionless flowmeter reading
to SLPM (standard liters per minute), based on operating pressure and required purity. The flow
control valve is used to set the flow rate through the system. The outlet pressure regulator allows
the user to set the pressure of the emergent nitrogen gas stream.

Description
The Parker Balston Nitrogen Generator is a completely engineered system which will transform
a compressed air supply into 95% to 99.5% purity compressed nitrogen. The system is based
on state-of-the-art membrane technology. Compressed air flows through the hollow fiber
membrane module and is separated into a concentrated nitrogen output stream and an oxygen
enriched permeate stream. The compressed nitrogen is filtered and delivered to the process or
equipment downstream. The permeate is vented to the atmosphere.
The Parker Balston N2-14A, N2-22A, and N2-35A Nitrogen Generators have integrated oxygen
analyzers and have been certified to IEC 1010 Standards (CSA 22.2 No. 1010.1-92). These
generators bear the CSA safety marking on the product label.
The Parker Balston Nitrogen Generators include all the components required to convert com-
pressed air into high purity nitrogen and monitor the purity of that nitrogen (Models N2-14A,
N2-22A, and N2-35A only).
The flow schematics in Figure 2 show all of the major components of the systems. Each system
can be broken down into five primary functional groups: prefiltration, air separation, flow con-
trols, final filtration, and nitrogen purity monitoring (Models N2-14A, N2-22A, and N2-35A only).

Note: In hazardous applications where the oxygen content is critical (i.e., blanketing
explosive chemicals or packaging food for extended shelf life), an oxygen monitor and/
or trace oxygen analyzer should be used in conjunction with safety interlocks and/or
alarm systems to assure proper nitrogen purity levels at all times.
An oxygen analyzer has been incorporated into the design of the N2-14A, N2-22A, and
N2-35A Nitrogen Generators to monitor the oxygen content of the nitrogen process stream. The
sensing device in the oxygen analyzer is a galvanic cell. The analyzer has an internal tempera-
ture compensation circuit to provide accurate readings within a specified temperature range.
The oxygen analyzer has all the controls necessary to assure safe and accurate monitoring of the
oxygen concentration in a process stream. The analyzer is equipped with the following controls
and features (see Figure 3).

General
The Parker Balston Nitrogen Generator is shipped on a wooden skid. The generator may be
removed from the skid when it arrives at the customer location, or it may be transported to its
final destination while skidded. If the generator is removed from the skid, use a two-wheeled
dolly. If the generator remains skidded while being moved, use a device approved for transport-
ing skidded products.
The Parker Balston®Nitrogen Generator is a free-standing unit. Do not suspend the nitrogen
generator from a wall or ceiling. Its considerable weight and size could pose a falling
hazard.
The inlet and outlet ports on the generator are 1/4” female NPT. A 1/4” male connector rated for
145 psig (10 barg) should be used to connect to the nitrogen generator. (Note: Parker recom-
mends that the inlet piping and fittings in the compressed air delivery system be of the same
size or larger than the inlet fittings on the Nitrogen Generator. This will help ensure an adequate
supply of air to the generator.) Consult Figure 4 for the location of the following recommended
external controls.
Shutoff Valve - A shutoff valve should be installed directly upstream from the nitrogen genera-
tor to facilitate routine maintenance and troubleshooting procedures. The valve used should
always be opened slowly. Opening a valve quickly will pressurize the membrane too rapidly
and may cause membrane rupture. Membrane failures resulting from improper valve installation
will not be covered under warranty.
Installation
Alarm Controls - The alarm controls are located on the right side of the oxygen analyzer panel.
The switch on the far right side of the front panel enables the audible alarm. When enabled, the
audible alarm will sound if the oxygen concentration in the process stream exceeds the alarm
set points set by the user. The alarm set switch is located to the left of the audible alarm control
switch. The two potentiometers used to set alarm trigger points are located to the left of the
alarm set switch. The LEDs above and below the alarm set switch give a visual indication of
oxygen concentrations beyond the specified range.
Oxygen Concentration Display - The oxygen concentration LED display shows oxygen con-
centration, in percent, to the nearest 0.1%.
Calibration Controls - The calibration controls are located to the left of the oxygen concentra-
tion display. The zero potentiometer is used to zero the instrument when a zero gas (containing
no oxygen) is introduced. The span potentiometer is used to set the analyzer reading to the
specified concentration of oxygen in the span gas. The inlet port to the generator for the calibra-
tion gas is 1/8” NPT and is located on the back of the generator, as shown in Figure 1. The
switch located below the calibration port (see Figure 1) is toggled up for calibration and down for
nitrogen purity monitoring.

Location
Pressure Regulator - A pressure regulator should be installed directly upstream from the nitro-
gen generator to set and maintain the inlet air pressure. Maintaining a constant inlet air pressure
is critical to the performance of the system. The regulator should be properly sized to prevent a
pressure drop at the generator inlet.
Flow Controller - If the application requires nitrogen at pressures higher than 10 psig
(0.7 barg), install a flow controller downstream from the nitrogen generator, close to the point of
use (see Adjustment Procedure in Operation section).
Hydrocarbon Scrubber - The installation of the Parker Balston Hydrocarbon Scrubber
P/N 72-905 on the outlet of the nitrogen generator (see Figure 4) is recommended for applica-
tions requiring very high purity detection levels. The life of the Hydrocarbon Scrubber depends
upon the flow rate of the generator. The lower the flow the longer the scrubber will last.
The generator should be located indoors, protected from severe weather conditions, and free
from excessive ambient dust or dirt. Do not install the generator outdoors. The ambient
temperature of the air surrounding the generator must be between 60°F and 95°F (15°C and
35°C). The environment surrounding the nitrogen generator should also be adequately venti-
lated; allow a minimum of 6” (15 cm) clearance on all sides of the generator.
The generator creates a 30% to 40% oxygen permeate stream which may pose a flam-
mability problem in an oxygen sensitive environment.
Consult Figures 4 and 5 for the recommended location of the following external con-
trols.
Compressed Air - The Parker Balston Nitrogen Generator requires a source of clean, dry
compressed air between 60 psig and 145 psig for operation. The incoming air should also be
between 60°F and 95°F (15°C and 35°C), and relatively free of water, compressor oil, hydrocar-
bons, and particulate matter. An oil content of <0.01 mg/m3is recommended. The compressed
air dewpoint is recommended to be less than or equal to 40°F (5°C) at 145 psi. The compressed
air consumption varies with inlet pressure and nitrogen purity. Consult chart in System Specifica-
tion Section to ensure an adequate supply of compressed air is available for the generator.
Power - A 120 VAC or 240 VAC, 50/60 Hz power supply is required to energize the oxygen
analyzer. (Note: Main supply line voltage must be within 10% of the nominal rated voltage for the
generator.) The power receptacle is located on the back of the unit (see Figure 1).
The Parker Balston Nitrogen Generator is preset at the factory for operation at 120 VAC. The
voltage setting for the generator is shown through a small window on the power entry module
on the back of the generator. Check the voltage selector setting prior to energizing the
generator. The selector setting should match the voltage of the local power supply and the
product label.
If the voltage selector displays an input power voltage different from the local power supply, it
may be changed using only a small screwdriver. (Note: The “NA” version of the generator
is designed to operate at 120 VAC only.) First, use the screwdriver to release the cover of the
power entry module on the back of the generator (see Figure 1). Next, rotate the voltage selector
until the desired input voltage is displayed in the window. Finally, replace the power entry module
cover.
Drain Lines - The drain line from the first two stages of prefiltration will consist of water and
compressor oil and should be piped away to an appropriate disposal container.
In many applications, the flow requirements for nitrogen can fluctuate with time. As noted earlier,
if the flow rate of the nitrogen stream varies, the purity level of the nitrogen also varies; therefore,

it is important to keep the nitrogen flow as constant as possible. A receiving tank can be installed
between the nitrogen generator and the process to accommodate fluctuations in nitrogen demand
and maintain nitrogen purity.
If a receiving tank is to be used, a back pressure regulator and a check valve should be installed
between the Parker Balston Nitrogen Generator and the receiver tank (see Figure 4). The Parker
Balston 72-460-V883 Back Pressure Controller contains both of these components and may be
ordered as an accessory for the nitrogen generator. The adjustable back pressure regulator, when
set to the appropriate pressure, will maintain a constant pressure drop across the flow control
valve. By controlling the pressure drop across the flow control valve, the nitrogen flow will be kept
constant and the variability in purity of the nitrogen process stream will be minimized. The check
valve, when installed properly, will prevent any flow of nitrogen from the receiver upstream toward
the generator, providing a more effective means of storing the nitrogen.

The high and low limits of the alarm may be set anywhere between 0.5% and 25% oxygen,
depending on the process limitations. To set the high alarm set point, press the alarm set switch
upward and adjust the high potentiometer until the display shows the desired high alarm set
point. To set the low alarm set point, press the alarm set switch downward and adjust the low
potentiometer until the display shows the desired low alarm set point.
The oxygen analyzer also includes high and low alarm relay contacts located inside the service
panel. The oxygen analyzer, through the use of the alarm relay contacts, may be used to control
the outlet stream (see Figure 7). For example, a high or low oxygen concentration could signal
a remote alarm, open a backup supply of nitrogen, or shut the generator down for protection
of downstream equipment or processes. The alarm relay contacts must be wired by a qualified
electrician. Both the high and low oxygen alarm conditions are provided with three relay outputs:
a common (C), a normally open (NO), and normally closed (NC).
To eliminate the possibility of electrical shock, disconnect the power cord before wir-
ing the alarm relay contacts to outside circuitry.
The relay contacts are rated for 250 VAC, 5 amps resistive or 3 amps inductive load or
24 VDC 5 amps resistive or 3 amps inductive load. Do not exceed these values in order
to maintain the instrument safety certification.

Plug the power cord into the power receptacle of the generator, and plug the opposite end into a
nearby wall outlet with earth ground protection. (Note: There is no power switch on the generator.
The oxygen analyzer is energized when the generator is plugged in.)
The inlet and outlet connections to the Parker Balston Nitrogen Generator must be checked for
leaks prior to system start-up. After the system is properly installed and checked for leaks, the inlet
gate valve can be opened to introduce compressed air to the system.
During start-up and adjustment of the system, the nitrogen produced by the unit will be of variable
purity. If the application for the nitrogen is critically dependent on purity, the nitrogen produced dur-
ing start-up or adjustment should be vented.
If the outlet nitrogen flow is closed, the system will still consume compressed air. The inlet air is
simply vented to atmosphere through the permeate ports of the membrane module.
Startup
Operation: Calibration (Models N2-14A, N2-22A and N2-35A only)
The customer is responsible for the circuitry utilizing these relay outputs and should
use good engineering safety practices in the design of this circuitry.
1 Strip all connecting wires to 1/4” to 3/8” (6mm to 9mm) using wire strippers.
2 Insert small screwdriver into the hole below the wire connection point and
press to open connector.
3 Slide the stripped wire end into the connection port until it “bottoms out”.
4 Remove the screwdriver to clamp the wire into the connection port. Pull the
wire gently to test integrity of the connection. Repeat this procedure from step
2 if the wire releases easily.
5Thread wires through electrical access opening on right side of generator (see
Figure 1).
CAUTION: the oxygen analyzer will not provide accurate readings unless calibrated on a
regular basis.
The oxygen analyzer is calibrated prior to shipment; however, Parker Balston strongly recom-
mends re-calibrating the unit prior to initial start-up. After the initial start-up, the analyzer should
be calibrated on a bi-weekly basis until a suitable schedule is determined, based upon the level of
accuracy required by the application.
There are two methods of calibrating the oxygen analyzer: the two point method and the single
point method. In the two point method, the first point in the calibration range is set to zero using
a zero gas (zero percent oxygen), and the second point in the range is set to a known percentage
of oxygen using a span gas (known quantity of oxygen, per gas supplier) or compressed air (20.9%
oxygen). In the single point method, only one point in the calibration range is set, using either span
gas or compressed air. Maximum accuracy in oxygen concentration monitoring will be achieved if
the oxygen concentration in the span gas is within the range of the expected oxygen concentration
in the process stream and the pressure of the gas closely approximates the pressure of the nitrogen
gas (See Figure 3 for calibration controls).
Oxygen analyzer readings should be checked and the analyzer re-calibrated on a routine basis. If
the nitrogen purity level falls below the desired level, re-calibrate the analyzer or adjust the flow until
the proper nitrogen purity level is reached.
The procedure for the two point calibration method is as follows:
1Throw the toggle switch on the back of the unit to the upright position, toward the calibration
port.
2Connect a tank of zero gas to the calibration port. (Gas pressure should be approximately equal
to operating pressure.)
3Allow the zero gas to flow through the unit until the reading on the oxygen concentration display
stabilizes.
4Adjust the Zero potentiometer until the oxygen concentration display reads zero.
5Disconnect the zero gas from the calibration port, and connect a tank of span gas or a source of
clean compressed air (set gas pressure to operating pressure).

Operation: Adjustment Procedure (All Models)
The user must determine the nitrogen purity, flow rate, and pressure required by the application prior
to adjusting the system for desired outlet nitrogen purity and flow rate. The inlet air pressure must be
constant in order for the system to supply nitrogen of consistent purity to the application. The inlet
pressure to the Parker Balston Nitrogen Generator should be maximized (within process and genera-
tor parameters) to optimize the operation of the membrane module. The required inlet air flow rate
and all flow and purity specifications for different operating conditions are shown in the Adjustment
Procedures in the Operation Section.
Note: There will be a 10 to 15 psig pressure differential between the pressure of the compressed air
supply at the inlet and the operating pressure of the membrane module. All flow rate/purity charts are
based on the operating pressure of the membrane module. This pressure loss must be taken into
account when determining the inlet pressure which will deliver the desired purity and flow of nitrogen
from the generator.
To adjust the outlet pressure, pull the pressure regulator knob out, adjust the pressure, and push the
cap back in to lack the setting. To adjust the dimensionless flow meter, turn the control knob until the
middle of the ball reads the desired setpoint.
A. Atmospheric pressure applications (<10 psig/0.7 barg)
If the Parker Balston Nitrogen Generator is being used to deliver nitrogen at or near atmospheric pres-
sure (e.g. purging or blanketing applications), use the following procedure for start-up and adjustment
of the system
1Open the (customer installed) inlet air gate valve.
2Adjust the (customer installed) inlet air pressure regulator until the Operating Pressure gauge (see
Figure 1) shows the operating pressure reading necessary to provide the purity and flow demanded
by the application, as shown in the purity/flow chart (see page 12).
3Adjust the Outlet Pressure regulator (see Figure 1) until the Outlet Pressure gauge
reads less than 10 psig (0.7 barg).
4Consult the Nitrogen Purity Label on the control panel of the generator (or the tables on page 12),
to determine the proper flowmeter setting for the required process nitrogen purity and operating
air pressure. Adjust the Flow Control valve on the control panel (see Figure 1) to yield the proper
flowmeter reading. The flow reading will be taken from the middle of the ball.
5Allow the system to reach equilibrium at the desired flow rate, pressure, and purity parameters.
This should take approximately 15 minutes.

B. Elevated pressure applications (>10 psig/0.7 barg)
If the Parker Balston Nitrogen Generator is being used to deliver nitrogen at an elevated pres-
sure (>10 psig/0.7 barg), use the following procedure for start-up and adjustment of the system.
(Note: In elevated pressure applications, the customer should install a flow controller down-
stream from the nitrogen generator, as detailed in the Installation section of this manual.)
1 Open the (customer installed) inlet air gate valve.
2 Adjust the (customer installed) inlet air pressure regulator until the Operating Pressure gage
shows the operating pressure reading necessary to provide the purity and flow demanded by
the application, as shown in the purity/flow charts (see page 12).
3 Turn the flow control valve to its fully open position.
4 Set the Outlet Pressure regulator (see Figure 1) to the desired outlet nitrogen pressure.
5 Consult the Nitrogen Purity Label on the control panel of the generator to determine the
proper dimensionless flowmeter setting for the required nitrogen purity and generator operat-
ing pressure. Adjust the (customer installed) Flow Controller until the dimensionless flowme-
ter shows the correct reading (based on the Nitrogen Purity Label or the tables on page 12).
The flow reading will be taken from the middle of the ball.
6 Allow the system to reach equilibrium at the desired flow rate, pressure, and purity param-
eters. This should take approximately 15 minutes.
C. Receiving Tank applications
After all the components have been properly installed (see Figure 5), the following procedure
should be followed to ensure optimal operation of the entire nitrogen supply system.
1Set the inlet pressure to the Parker Balston Nitrogen Generator using the customer-provided
pressure regulator, and initiate the air flow through the system.
2Set the flow control valve to its fully open position. The nitrogen flow meter reading should be
at the top of the scale.
3Close the shutoff valve to the process or instrument and open the vent valve downstream
from the receiving tank to prevent substandard nitrogen from entering the process.
4Fully open the Outlet Pressure regulator on the nitrogen generator, and adjust the Back Pres-
sure Controller until the Outlet Pressure gauge on the nitrogen generator reads 10
psig (0.7 barg) less than the desired nitrogen storage pressure. Maximize the storage pres-
sure in order to maximize the storage capacity of the selected receiving tank.
5Set the flow control valve on the front panel of the nitrogen generator to the proper reading,
as specified by the Nitrogen Purity Label, or the charts on the previous page.
6Purge the entire system for 5 minutes, venting the initial nitrogen stream through the vent
valve to atmosphere.
7Close the vent valve, open the process or instrument shutoff valve to initiate the flow of nitro-
gen to the system.
The use of a receiving tank upstream from the process, as detailed in this literature, significantly
reduces the effects of fluctuating nitrogen demand on the purity of the nitrogen process stream
from the Parker Balston Nitrogen Generator. A 5-minute purge of the system (see Step 3 above)
is needed each time the unit is started.
Note:
If more than minor adjustments of the downstream flow controller are required to reach the de-
sired purity level, please see the Troubleshooting section of this manual for further guidance.

Evaluation
System Upsets
Shutting Down
Temperature Equilibrium If the temperature of the inlet air to the Parker Balston Nitrogen Generator differs from the
temperature of the module (i.e. ambient temperature), the system must be allowed to reach
temperature equilibrium before a constant purity of nitrogen is delivered from the system. If the
temperature difference is 10°F-20°F (5°C-10°C), this equilibrium period may be as long as 60
minutes. The inlet air temperature and, more importantly, inlet air dewpoint, should not
be higher than the ambient temperature, or condensation of water within the system
may occur, resulting in damage to the generator.
Performance of the Parker Balston Nitrogen Generator is highly dependent on the temperature
of the inlet air. The data on purity and flow rate presented in this bulletin is based on an inlet air
temperature of 68°F (20°C). If the temperature of the inlet air at the point of use for this system
varies from 68°F (20°C) by more than 5°F (3°C), the factory must be consulted for flow and purity
information. If the temperature of the inlet air is expected to vary, install an Oxygen Analyzer (P/N
72-O2730NA) to provide assurance that the application is supplied with the desired purity of
nitrogen.
The performance and operating conditions of the Parker Balston Nitrogen Generator should
be checked at least once per month. This routine system check should include correcting any
changes in the flowmeter reading, confirming pressure gage reading stability and operating pres-
sure setting, and checking the downstream flowmeter (if applicable) to ensure flows are consis-
tent with the required nitrogen purity level.
The optimum performance of the nitrogen generator is dependent on system parameters
remaining stable and accurate; as such, the use of an oxygen analyzer to monitor system per-
formance is highly recommended.
System upsets relative to pressure or flow rate will result in variations in purity of the outlet gas.
System upsets relative to temperature, dewpoint, or hydrocarbon content of the inlet com-
pressed air may result in variations of the system performance. These types of upsets should
be eliminated from the compressed air delivery system to assure consistent performance of the
nitrogen generator.
Proper shutdown of the nitrogen generator can be accomplished by simply closing the inlet air
gate valve. If this valve is left open, the system will continue to consume compressed air. Clos-
ing the outlet flow control valve will not prevent air consumption because the membrane module
permeate ports are open to atmosphere.

Replacement
Before servicing the Parker Balston Nitrogen Generator, isolate the unit from the compressed
air supply and fully depressurize the system. Replacement component locations are shown in
Figure 8.
All maintenance activities for the Parker Balston Nitrogen Generators should be performed by
suitable personnel using reasonable care.
The required maintenance for the Parker Balston Nitrogen Generator consists of changing the prefilter
and final filter cartridges, replacing the activated carbon filter, changing the galvanic cell (Models N2-14A,
N2-22A, and N2-35A), calibrating the oxygen analyzer, and monitoring the performance of the system.
All filters are located behind the front filtration access panel. The recommended service schedule and
replacement part numbers are outlined in the Service Schedule at the end of this section. The locations
of all serviceable parts are shown in Figure 8. Replacement coalescing filter cartridges, final membrane
filter cartridges, and activated carbon filters have been assembled into a maintenance kit (P/N MK7572C)
which may be purchased through your local representative. The MK7572C Maintenance Kit provides one
year of filtration replacement components.
Servicing the Parker Balston Nitrogen Generator takes approximately 15 minutes. Remove the filter ac-
cess panel using a Phillips head screwdriver to access filtration components.
Remove the filter cartridges from the filter housings by: loosening the collar from the filter assembly, low-
ering the filter bowl away from the filter head, and unscrewing the element retainer from the base of the
cartridge. Insert the new filter cartridge and reassemble the housing in reverse order. Be sure to install
the proper grade filter in the proper housing (the housings are labeled).
The only tool required to change the activated carbon filter is a 7/16” (or adjustable) wrench or socket
wrench. To change the activated carbon filter, disconnect the tubing from the press fittings on the inlet
and outlet ports of the scrubber. (To remove the tubing from the press fittings, push the tubing into the
fitting, hold the collar of the fitting back, and pull the tubing out of the fitting.) Remove the 4 bolts that
hold the scrubber to the generator chassis (the mounting bracket should stay on the scrubber). Replace
with new scrubber and re-assemble. Please note that as of October 1, 2002, Parker has discontinued
the core credit and rebuild program for activated carbon towers and compressors. These items may be
disposed of locally by the customer. If there are disposal concerns, please contact the Technical Services
Department at 800-343-4048, 8AM to 5PM Eastern Time.
Do not remove the collar on the Hydrocarbon Scrubber.
The performance of the system should be reviewed on a monthly basis. This review should include
checking the settings for inlet pressure, outlet flow rate, and outlet pressure. If these readings have
changed from the original settings, adjustments must be made as described in the Adjustment Procedure
section of this bulletin. Calibration must be performed routinely on any oxygen analyzer being used with
the system. Consult the manufacturer for procedure and frequency of calibration.

Disconnect generator from power supply before replacing galvanic cell sensor.
The galvanic cell sensor degrades over time and should be replaced on an annual basis
(P/N 72695A). The only tools needed for this replacement are a Phillips screwdriver, a small
screwdriver, and wire strippers. The procedure for changing the sensor is outlined below and
takes approximately 10 minutes.
1 Remove filtration access panel and cell cover to expose galvanic cell holder (see
Figure 8).
2 Disconnect old cell wires from connectors.
3 Strip replacement sensor connecting wires to 1/4” to 3/8” (6mm to 9mm) using wire strip-
pers.
4Connect the stripped wires to the screw connections provided being sure to maintain the
proper polarity (black -, red +).
5Replace filter access panel.
This equipment has fuses in both neutral and phase lines. Use care when servicing.
Occasionally, one or both of the fuses (P/N 13221) in the generator may burn out. The fuses
are located in the power receptacle on the back of the generator. Before servicing the fuses,
disconnect the power cord from the power supply. Both fuses should be checked each
time fuse replacement is warranted. To access the fuses, use a small screwdriver to remove the
holder located in the power receptacle of the generator. Replace either one or both fuses as
necessary and re-assemble.
For continued protection against risk of fire, replace only with fuse of specified rating.
The product is not intended for use in extremely dirty environments. If necessary, the Parker
Balston 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. Use of any liquid
detergent to clean the generator could present an electrical hazard.

1The flow meter reading is dimensionless. Read flowmeter at the middle of the ball. The
actual flow at various operating pressures is converted into SLPM (standard liters per minute)
in the purity label flow chart on the unit.
2Minimum purity shown on the purity label in percent nitrogen. All nitrogen purities are ± 0.5%.
If a more accurate reading is required, use the Balston 72-730-V883 Oxygen Analyzer or a
trace analyzer.
3All data shown in the flow chart is based on an operating temperature of 68°F (20°C).
4At inlet air temperatures less than 68°F (20°C) or greater than 82°F (28°C) consult factory for
flow rates.
1The Parker Balston Nitrogen Generator should be installed in an area with adequate ventila-
tion to reduce the flammability of the oxygen-rich permeate stream. The system should not
be located in an area where the permeate stream poses the risk of explosion or combustion.
2Nitrogen is nontoxic and largely inert. It can act as a simple asphyxiant by displac-
ing oxygen in air. Inhalation of nitrogen in excessive concentrations can result in
unconsciousness without any warning symptoms such as dizziness, fatigue, etc.
3The maximum operating pressure of the system is 145 psig (10 barg). Operating the nitro-
gen generator at pressures above 145 psig (10 barg) will result in damage to the membrane.
4The recommended operating inlet air temperature for the nitrogen generator is 68°F (20°C)
or less. If the inlet air temperature will be higher than the ambient temperature, the com-
pressed air should be cooled and filtered, to remove water and oil, prior to heating for intro-
duction to the nitrogen generator. Do not use high temperature compressed air directly
from the compressor, this will permanently damage the membranes.
5The maximum operating inlet air temperature of the Parker Balston Nitrogen Generator is
95°F (35°C). If the inlet air temperature is above 95°F (35°C), the longevity of the membrane
will be reduced and the warranty will be void.
6The drain lines from the first two stages of filtration should be piped away to an appropriate
collection vessel or waste treatment system (open to atmospheric pressure) to avoid any pos-
sible re-entrainment of liquid in the air which feeds the membrane module.
7Changes in inlet pressure or outlet flow demand will alter the nitrogen purity.
8Use of any valve other than a gate valve (or other slow-opening valve) on the inlet air
supply will cause damage to the membrane module.

Symptom Course of Action
Check that the flow control valve on the generator is fully open and control the flow with a
valve at the process.
Check operating pressure to assure that it is greater than 60 psig
(4.1 barg).
Check the system for leaks.
Check operating pressure to assure that it is greater than 60 psig
(4.1 barg).
Check setting of flow control valve. Adjust if necessary.
Check the system for leaks.
Check setting of flow rate compared to specification.
Check the operating pressure to assure that it has not varied from the original reading.
Check the system for leaks.
Measure the temperature and dewpoint of the inlet air. The recommended temperature is
68°F (20°C) and the recommended dewpoint 60°F (15°C) or lower.
Calibrate oxygen analyzer (if needed).
Remove tubing from the drain and hold finger over drain opening for a few seconds to allow
pressure to build, and drain to seal.
Check inlet pressure. It should be greater than 15 psig (1 barg) to seal drain.
Remove bowl from filter assembly and rinse with water.
If leak persists, replace automatic float drain. (P/N 21552)
