All installation, operation, and maintenance procedures for the Parker Balston Hydrogen
Generator should be performed by suitable personnel using reasonable care.
The Parker Balston H2PD-150 and H2PD-300 Hydrogen Generators are free-standing bench-top
units.
Do not suspend the hydrogen generator 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 excessive ambient dust or dirt.
Do not install the generator
outdoors.
The ambient temperature of the air surrounding the generator must be between 50°F and
104°F (10°C and 40°C). 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 the hydrogen supply.
The Parker Balston Hydrogen Generator weighs 58 lbs. (26 kg.) Use proper equipment and lift-
ing techniques for transporting this equipment to its installation location. The hydrogen generator
is intended to remain stationary when filled with water and electrolyte. If necessary, the generator
may be relocated over
short
distances when filled.
Do not grasp the front panel when moving
the hydrogen generator.
Lift the generator by the metal case only. The generator should remain
upright when moved. For long distance moves, the generator must be shut down and drained. (See
Shutdown section of this manual.)
Power -
The Parker Balston Hydrogen Generator may be operated by a 120 VAC or a 230 VAC,
50/60 Hz power supply.
(Note: Main supply line voltage must be within ±10% of the nominal
rated voltage for the generator.)
See product label on the rear panel of the hydrogen generator for
factory voltage setting. To connect the generator to the power supply, simply plug the female end of
the electrical cord into the receptacle on the right side of the generator, and the opposite end into a
three-pronged earthed power receptacle.
Note: Protect the generator from sudden, transient fluctuations in electrical power by using
a surge suppressor. Parker recommends using a surge suppressor meeting the following
specifications:
Joule Rating
1000 or greater
Surge Amps
84,000 or greater
Max Noise Reduction
80+ (db)
Deionized Water -
The Parker Balston Hydrogen Generator must be supplied with deionized water
on a regular basis. The water should be 5 Megohm-cm, or better quality deionized water.
Caution: Do not use tap water or deionized water with less than 5 Megohm-cm resistivity.
Metallic ions and suspended solids present in substandard water may poison the palladium
membrane, rendering the cell inoperable. If the generator is operated with any liquid other
than 5 Megohm-cm (or better) deionized water, the warranty will be void.
Piping -
The outlet connections for the Parker Balston Hydrogen Generators are a 1/8” compres-
sion fitting. All tubing and fittings downstream from the hydrogen generator should be clean stain
-
less steel to minimize contamination of the hydrogen 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 Parker Balston Hydrogen Generator. The piping configuration for the
hydrogen delivery system should include a means for venting subpurity hydrogen generated during
system warm-up. This may also be accomplished by disconnecting the downstream instruments.
Parker strongly recommends the installation of a shutoff valve and pressure regulator at the process
or instrument being supplied with hydrogen from the generator. (If the process or instrument has its
own internal shutoff valve and pressure regulator to isolate it from the hydrogen line, this installation
is unnecessary.)
For convenience, the hydrogen stream from the Parker Balston Hydrogen Generator is manifolded
for carrier and fuel gas applications. There is no difference in hydrogen quality between the two
ports. The generator is shipped with a 1/8" ferrule fitting on the fuel gas port and a pipe plug on the
carrier gas port. If hydrogen is being used as a carrier gas, simply remove the pipe plug from the
carrier port and replace with the nut and ferrule supplied in the accessories bag.
(Note: If one port
is not being used, it must be capped.)
The combined flow from the carrier and fuel gas ports must
not exceed the capacity of the generator.
