The Hydrogen Generator Model A915000JA-L1555 (see Figure 1), is a completely engineered
system designed to produce ultra-pure, dry hydrogen gas from deionized water using a Pro-
ton Exchange Membrane Cell. The hydrogen generator utilizes the principle of electrolytic
dissociation of water and hydrogen proton conduction through the membrane. The hydrogen
stream is dried using a coalescing filter, a drying tube, and desiccant. The outlet pressure of
the unit is 90 psig (6.2 barg) with a maximum hydrogen delivery flow rate of 160 cc/min for
Model 9150.
The hydrogen generators are ideal for use as fuel gas in Flame Ionization Detectors (FIDs),
Trace Hydrocarbon Analyzers, and other general laboratory equipment requiring a source of
pure hydrogen.
The 9150 Hydrogen Generator is certified to the electrical safety requirements as specified
by the IEC, CSA, and UL standards. These units bear both the CSA and UL markings on the
product label. Product supplied to Europe carries the CE mark (230 VAC units only). The

Note: All installation, operation and maintenance activities for the hydrogen generators
should be performed by suitable personnel using reasonable care.
The hydrogen generators are free-standing bench-top units. Do not suspend the genera-
tor from the wall or ceiling. Its weight and size could pose a falling hazard. The generator
should be located indoors, protected from severe weather conditions, and free from exces-
sive ambient dust or dirt. Do not install the generator outdoors.
The ambient temperature of the air surrounding the generator must be 40 - 100°F (4 - 38°C).
Do not place the generator in an area where there is a chance of freezing. Place the
hydrogen generator in an upright position, on a level surface, in close proximity to both the
electrical power supply and the equipment requiring hydrogen.
See end of Manual for a list of the symbols displayed on the generator and referred to in this
Manual.
The hydrogen generator weighs 40 lbs (19 kg). Use proper equipment and lifting tech-
niques for transporting this equipment to its installation location. The hydrogen generator
is intended to remain stationary when filled with water. If necessary, the generator may be
transported over short distances when filled. Do not grasp the front panel when moving the
generator, lift only from the bottom. Keep the generator in an upright position.
Remove all red tape from the top cover, the back panel and on any other surfaces. Open the
top cover of the hydrogen generator. Unscrew the desiccant cartridge cap (see Figure 2) and
remove the red tape covering the outlet port located on the inside of the desiccant cartridge
housing. Remove the red cap sealing the hydrogen outlet fitting on the back of the unit.
Desiccant - Wipe any drops of moisture with a lint-free cloth or paper towel from the desic-
cant cap and housing. Remove the desiccant cartridge from the sealed bag. Use a drop of
deionized water to wet the o-rings. Insert the cartridge into the housing, nipple end first (see
Figure 3). Firmly push down on the cartridge to create a hydrogen-tight seal at the bottom of
the housing (see Figure 4), making sure the cartridge is seated.
Before replacing the desiccant cartridge cap, make sure the large Viton®o-ring is centered
inside the cap (See Figure 5). Screw the cap on and tighten securely by hand. Make sure
that the o-ring is still centered and that the o-ring has created a dark ringed seal.
Note: Most leaks occur due to improper sealing of the cap to the housing on the desiccant
cartridge.
Deionized Water Bags - Remove the deionizer bags from the plastic shipping container
and inspect for holes or tears. Insert the “T” end of the plastic cable running through the
deionizer bag into the hole of one of the water reservoir caps (see Figure 6). Pull the “T” end
through the hole to the outside of the cap. Repeat for the other cap. Do not let any foreign
material fall into the water bottles. Insert one bag into each water reservoir.
Power - The hydrogen generators may be operated by a 100-120 / 200 -240 VAC, 50-60 Hz
single phase power supply. To connect the generator to the power supply, simply plug the
female end of the electrical cord into the receptacle on the back of the generator, and the
opposite end into a three-pronged grounded power receptacle. The power receptacle must
be protected from voltage surges.
Deionized Water - The hydrogen generator must be supplied with deionized water with
a resistivity of at least 2 MegOhm/cm. The use of water with a value less than 2 meg-
Ohm/cm will damage the cell and void the warranty. Parker Hannifin provides a point
of use accessory, the HydroGen™ Mate (P/N 72-230), that produces high purity water
(>5 MegOhm/cm) from tap water for manually filling the generator.

Caution: Cell contamination is a cumulative and irreversible process, which will eventually cause an
over-voltage, automatically shutting down the generator. The deionizer bags are for a final decontamina-
tion stage and should not be used to purify low grade water.
Piping - The outlet connection for the hydrogen generator is a 1/8” compression fitting. All tubing and fittings
downstream from the hydrogen generator should be clean stainless steel to minimize contamination of the hy-
drogen stream. If copper tubing has been used with hydrogen in the past and has yielded acceptable results,
there is no need to alter an existing piping configuration to install the hydrogen generator.
Pressure Regulator - The pressure is controlled using the Pressure Adjust control knob located on the front
panel, exposed when opening the front gray panel door (see Figure 7). The pressure can be monitored using
the gauge located on the front. Do not set pressure regulator higher than 90 psi. There is a Pressure Relief
valve that is set for 125 psig (8.6 barg) in case of internal pressure build up. The expelled gas is channeled
through the Pressure Relief Port located on the back of the unit.
Shutoff Valve - The generator includes a shutoff valve located on the front panel behind the gray door (see
Figure 8). Use this valve to shut the unit off when not in use. In case of extended periods of downtime see the
Operation / Shutdown / Storage sections of this manual.

Water Reservoir
Initial Startup
After carefully following all the preparation procedures in the Installation section, open the top panel
and remove the water reservoir caps with the deionizer bags already attached. Fill both reservoirs
with deionized water until the level in the tank reaches the “Full” mark. It will take approximately 4
liters of deionized water to fill the generator.
Remove the plug on the drain port located behind the gray front panel of the generator (see Figure
7). Insert the drain tube fitting (with drain tube attached) into the drain port and remove about 100 ml
of water to test the check valve (see Figures 8, 9).
Note: The generator will automatically shut down if the water level becomes too low, or the water
quality is not sufficient.
Make sure that the deionizer bags are fully immersed in the water and that they do not block the
outlet port on the bottom. Do not block the small vent hole in the water reservoir cap with the “T”
fitting or anything else. Be sure to remove all of the red tape that was applied to the unit for shipping
purposes. Do not let the deionizer bags dry out.
Open the gray panel door on the front of the generator to expose the generator controls (See Figure
8).
1Turn the Shutoff Valve to the closed position (see Figure 7 showing the valve in the Open posi-
tion).
2Connect the electrical power cord to the generator receptacle, and connect the other end to a
surge protected wall receptacle.
3Set the Pressure Adjust control (see Figure 7) to the desired pressure setting using Table 1 as an
approximate guide.
Note: The Pressure Adjust control is marked in divisions from 1 to 1000. The hundreds are read in the
window on top of the control, the tens are read from the numbers on the dial face, and the single units
are interpolated using the hash marks between the tens. Use the small lever on the side of the control to

lock the dial.
4Turn the Power Switch ON (located in the rear of the generator, in the power receptacle).
Note: The generator is now producing hydrogen at the requested pressure. As the unit approaches the
desired pressure, the Hydrogen Flow Indicator light may flicker, dim or even go out. This is normal oper-
ation. It will take approximately 15 minutes to reach full operating pressure internally.
5 Connect the external piping to the generator. While monitoring the Output Pressure Gauge on
the front panel, slowly turn the Shutoff Valve to the OPEN position (see Figure 7).
6The pressure will drop initially, the magnitude of which is dependent upon the length and diame-
ter of tubing used, and volume of the connected equipment downstream. After a short time the
pressure should begin to recover. Once pressure has recovered, open the outlet valve a little
Follow the instructions listed in the Initial Startup section. If the pressure continues to drop, the High
Hydrogen Flow (Mass Leak) light will illuminate (see Figure 7). A Mass Leak may be caused either
from a leak in the piping to the equipment or it may indicate that the volume being filled is too large
for the generator. If it is determined that a Mass Leak is present, please follow the procedure below:
1Close the Shutoff Valve (see Figure 7, shown in the OPEN position).
2Turn Power switch (located in the rear of the generator in the power receptacle) OFF and then
turn Power switch ON.
3Re-pressurize the generator.
4Repeat the Initial Startup procedure three times to verify the leak.
If the system continues to detect a leak, check all the external tubing connections and make sure that
the volume is not too large for the generator purchased. If the leak persists, check the fittings inside
the generator, especially the o-ring seal on the desiccant cap. Make sure the desiccant cap is tight.
If there are no leaks found in internal or external connections, install a flow control valve or needle
valve downstream from the generator, as close to the outlet as possible. Set the flow control for the
desired flow rate making sure not to exceed the maximum flow rate of the generator.
Caution: Do not use commercial leak detection fluids on any Lexan®plastic parts in the generator.
These fluids may cause cracking and crazing which results in leaks. Use a solution of 4-5 ml of liquid
dish soap in one liter of water.
Caution: Use extreme care when checking for internal leaks. Due to the nature of the gases
involved use a protective face shield or other appropriate equipment whenever servicing or trouble-
shooting the generator with the cover removed.

Shutdown
Storage
To maintain the highest gas purity, the hydrogen generator should be run continuously.
Monitor the hydrogen consumption of the downstream equipment to ensure flow is within the
capacity of the generator (see the Systems Specification section for rated flows). Both the Power
Indicator light and the Hydrogen Flow Indicator light should be illuminated (see Explanation of
Symbols at the back of the manual).
The water level should be monitored regularly and refilled as necessary. The reservoirs hold
enough water for at least a week of continuous operation. Water can be added by removing the
cap of the water reservoir (do not pull the deionizer bag out) and adding enough water to reach
the Full mark on the front view port. Replace the cap making sure the deionizer bag does not
block any of the ports.
To maintain the integrity of the hydrogen cell, follow the guidelines listed below:
• Keep a supply of deionized water in the reservoir above the Refill line at all times.
• Minimize the “dead volume” in the piping between the generator and the downstream equip-
ment.
• Never expose the unit to temperatures below freezing.
• Never abruptly open the Shutoff Valve to large volumes. The large hydrogen demand can
trigger the Mass Leak safety feature and possibly damage the cell.
If the built-in diagnostics trigger a fault LED to illuminate, consult the Troubleshooting section of
this manual for further instructions. The generator is designed to be run continuously 24 hours, 7
days per week.
If the unit is to be idle for more than 24 hours, the generator should be turned off.
To store the unit:
1Turn the Pressure Adjust knob to zero (see Figure 8). Wait until the outlet pressure gauge
reads zero.
2Cap the Hydrogen Outlet on the back of the generator or leave it connected to the down-
stream equipment.
3Fill the tanks at least half full with deionized water. Make sure that the cell has a least 2”
(5 cm) of water showing in the cell assembly tube. This can be viewed from the hole in the
back of the generator.
4Remove the desiccant cartridge and store it in a moisture proof container.
Operation
Controlled Venting After replacing any parts downstream from the generator, or upon initial startup, the system will
need to be purged in order to achieve the final purity. To avoid contaminating the downstream
equipment, the user should install a three way valve in-line, nearest to the equipment, and install
a variable restrictor (such as a needle valve) on the outlet port of the generator. Follow the sim-
ple procedure below:
1Close the Shutoff Valve (see Figure 7, shown in the Open position).
2Set the Pressure Adjust knob to the desired pressure (see Figure 7).
3Press Start and wait until the internal pressure reaches the desired pressure (approximately
15 minutes).
4Set the output flow rate to 50 cc/min by using the downstream equipment or if a three-way
valve was installed then switch the flow to the outlet (or purge port) and set the flow rate
using a needle valve. Use the downstream equipment for flow control only if impure hy-
drogen will not ruin the equipment.
5Allow the system to vent in this manner for 30 minutes. The generator and lines should now
be purged of air and ready for use.

Indicators
The Parker Balston Model 9150 hydrogen generator has built-in system diagnostics to
monitor the operation of the generator and alert the operator in case of failure. There is a
Power Indicator light on the front panel of the generator to signal the operational status of the
system (see Figure 10).
The control circuitry restricts the membrane cell current to a safe level and eliminates the
possibility of excessive hydrogen production. If a fault occurs and an indicator is illuminated,
follow the instructions in the Troubleshooting section to clear the fault.
Note: See the Explanation of Symbols section on the loose sheet in this manual to match the
symbols on the generator to the descriptions listed below.
Hydrogen Flow Indicator - The Hydrogen Flow Indicator light illuminates to indicate the cell is
generating hydrogen (see Figure 10).
Flow Check Bar Graph - In normal operating mode (the side Mode Button is out), the bar
graph displays the percentage of flow produced by the system (see Figure 10). where the flow
is displayed from High (160 cc/min) to Low (less than 5 cc/min).
No Hydrogen Flow Indicator - The No Hydrogen Flow Indicator light illuminates to indicate
the cell is no longer generating hydrogen (see Figure 10).
High Hydrogen Flow Indicator (Mass Leak) - The High Hydrogen Flow Indicator (or Mass
Leak detector) illuminates to warn the user that the hydrogen demand is exceeding the sys-
tem capacity. This may be caused either from a leak in the piping to the equipment or it may
indicate the volume that is being filled is too large for the generator. The High Hydrogen Flow
Indicator will stay illuminated for approximately 10 seconds, then the unit will shut down and
the no hydrogen flow indicator will be illuminated. Once the fault has been corrected, press
the START button to reset the generator and initiate hydrogen flow (see Figure 7).
Diagnostics
5During long periods of shutdown or storage (>3 months), the generator should be run for
1-2 days every 3 months to ensure that the cell remains hydrated and the water quality
intact.
If the generator is being returned to Parker, contact the Technical Support Services Depart-
ment at 800-343-4048 for a Return Authorization (RA) number and new packaging if the origi-
nal is no longer available.
1Turn the Pressure Adjust knob to zero (see Figure 7). Wait until the outlet pressure gauge
reads zero.
2Drain most of the water from the water reservoirs using the Drain Port Insert (connected
to a length of tubing). Leave a half inch of water in the reservoirs to ensure that the cell
remains hydrated. Connect the drain port insert to the Drain Port located on the front
panel behind the gray door (see Figure 8). Drain the deionized water into a 4 liter contain-
er.
3After the unit has been drained, press down on the metal tab on the top of the Drain Port
connector to remove the Drain Port insert and tube (see Figure 9).
4Remove the desiccant cartridge and store it in a moisture proof container. Replace desic-
cant vessel cap.
5Pack the generator carefully in the original packing box or request new packaging from
Parker Hannifin. Be sure to display the RA number on the outside of the box for prompt
response.
6In order to maintain the warranty on the generator, ship the generator in a manner that

Hydrogen Purity
Change Water Indicator - If the water quality in the reservoir reaches the Low level, the
Change Water Indicator (see Figure 7) will illuminate. The water in the unit must be changed
and the deionizer bags must be replaced.
Water Check Bar Graph - If the Mode Button is pressed in on the Parker Balston 9150, the
Bar Graph will display the Water Check quality (see Figure 10). The Bar Graph indicates the
water quality level from High (>2 MegOhm/cm) to Low. This quality level corresponds to the
changes in the current going through the water.
Low Water Indicator - If the water level drops too low in the water reservoir, the generator will
stop producing hydrogen.
Blue (or orange) colored indicator beads are located in the bottom half of the desiccant car-
tridge. The blue beads turn gray or beige (the orange beads turn clear) as water is adsorbed
in the cartridge. When this happens, the desiccant should be changed immediately, or the
water content in the hydrogen stream will increase dramatically.
Note: If low moisture (1 ppm or less) is required, the desiccant cartridge must be replaced be-
fore all the indicator beads change color. An external water trap can be used downstream from
the generator for increased water removal.

General
Water Refill
Desiccant Cartridge
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.
With proper care and maintenance the hydrogen generator 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.
The primary maintenance tasks required are changing the desiccant cartridge (when the
beads turn color or clear), replacing the deionizer bags (approximately every 6 months), and
refilling the water reservoirs (weekly). See page 11 for replacement part numbers and recom-
mended service frequency.
Do not use water, aerosols, or other cleaning agents on the unit. If necessary, the generator
can be wiped down with a clean dry cloth on an as needed basis. Use of any liquid detergent
to clean the generator could present an electrical hazard.
Do not use commercial leak detection fluids on any Lexan®plastic parts in the generator.
These fluids may cause cracking and crazing which leads to component failure. Use a solu-
tion of 4-5 ml of liquid dish soap in one liter of water.
Refill the water in the generator whenever the water level reaches the Refill level displayed on
the front panel (see Explanation of Symbols at the back of the manual). The water reservoirs
should last approximately 1 week when the reservoirs are filled to the Full level. Water must
have a minimum resistivity of 2 MegOhm/cm.
If the Low Water indicator (see Figure 7) illuminates, the generator will stop producing hydro-
gen to safeguard the cell from permanent damage. Add water to the generator until the Full
level is reached and press the Start button to generate hydrogen.
No tools are needed to change the desiccant cartridge (P/N 1647727). The cartridge should be
replaced when the color of the indicator beads changes. The blue beads turn to beige or gray
and orange beads turn clear. After all the indicating beads have turned color, the cartridge will
have approximately 2 days of life left at 90 cc/min flow and 8 hours left at 500 cc/min flow.
1Turn the Power switch OFF and leave the Shutoff valve in the OPEN position (see Figure
8, valve is in the OPEN position) to vent the hydrogen from the unit. Ensure that 0 psig is
shown on the pressure gauge.
2Lift the top cover and unscrew the cap covering the desiccant cartridge (see Figure 2).
Remove the cartridge from the generator.
3Remove the new desiccant cartridge from the moisture proof bag. Add a small amount
of deionized water to wet the o-rings on the nipple end of the desiccant cartridge. Push
down firmly to seat the o-rings at the bottom of the housing (see Figure 3).
4Replace and center the large o-ring inside the desiccant cap (see Figure 4). Tighten the
cap securely by hand. Be sure the o-ring seal remains centered and the seal is visible as
a black ring around the top and sides.
Note: Most internal leaks are found at the desiccant housing cap o-ring seal, due to improper
sealing of the cap. Be sure to seal the cap tightly.
5Turn the Power switch ON and perform the controlled venting purge as described in the
Startup section, then begin using the generator.
Note: For best results, purge the system for one hour to remove any residual oxygen and mois-
ture from the instrument and piping downstream.

Cartridge
Regeneration
Deionizer Bag
Replacement
Fuse Replacement
When the desiccant becomes saturated with moisture the blue indicating color will turn beige
or gray or the orange indicating color will turn clear. If the expended desiccant cartridge will be
regenerated for later use, it must be stored in a moisture-proof container.
Cold Vacuum Oven - For best results place the desiccant cartridge in a cold vacuum oven
and ramp the temperature at 2°C/minute to 150°C while supplying a vacuum. Do not exceed
175°C. Regeneration will be complete in 8 hours.
Conventional Oven - If only a conventional oven is available, place the cartridge upright inside
the oven to allow the moisture to leave from the top of the cartridge. Apply the following ramp
rate and procedure:
• 2°C/min from room temperature to 90°C, hold at 90°C for two hours.
• 2°C/min from 90°C to 150°C and hold at 150°C for 24 hours.
• Cool the cartridge in a desiccator or low moisture environment until needed in the hydrogen
generator.
For either method, do not exceed 175°C. The temperature will not affect the desiccant per-
formance; however, once the beads turn black (for the blue indicator) or remain clear (for the
orange indicator), they can no longer be used as a color indicator.
Apply a light coat of water to the o-rings prior to inserting the cartridge into the generator plas-
tic housing.
The water reservoirs should be rinsed and the deionizer bags replaced every six months, or
whenever the Change Water light illuminates (see Figure 7). No tools are necessary to change
the deionizer bags.
1Turn the Power Switch to OFF and make sure the Shutoff Valve is in the OPEN position
(see Figure 8) in order to vent the hydrogen from the generator.
2Lift the top cover and unscrew the water reservoir caps. Lift the deionizer bag out of the
reservoir along with the cap. Disconnect the deionizer bags from the caps and discard.
3Inspect the new deionizer bags (P/N 7601132) for holes or tears and return to Parker for
credit if damaged. Insert the “T” end into the cap until it secures the bag to the cap (see
Figures 2 and 3). Repeat for second bag.
4Use the Drain Port Insert with the 1/4” tube connected to it to drain the water reservoirs.
There is approximately 4 liters of water in the generator when full. Connect the Insert to the
Drain Port located on the front panel behind the gray door (see Figure 7) and drain the unit
(see Figure 8).
5Remove the Drain Port Insert by pressing down on the metal tab and pulling the fitting
out (see Figure 9). Refill the reservoirs with deionized water. Repeat steps 4 and 5 several
times.
6Finally, remove the Drain Port Insert and fill the reservoirs completely with approximately
4 liters of deionized water.
7Replace the caps, with the new deionizer bags attached, being careful to avoid blocking
any of the ports in the generator.
Note: Do not allow the deionizer bags to dry out, they must be immersed in water to perform.
8Start the generator in the same manner found in the Startup section.
Occasionally, the fuse in the hydrogen generator may burn out. The fuse is located in the pow-
er receptacle on the back side of the generator. Before servicing the fuse, turn the generator
off and disconnect the power cord from both the power supply and the generator power
receptacle.
To access the fuse, use a small screwdriver to remove the fuse holder located in the back of the
generator and in the power receptacle. Replace with the appropriate fuse and re-assemble.
To maintain the safety and performance integrity of the product, use only the fuse of the size
and type detailed in the Specifications, Parts, and Accessories sections of this bulletin.
