2 Description
Parker Hannifin zero air generators are designed to produce a supply of hydrocarbon free air from a clean, dry (IS0 8573-1:2010 class 2.2.1)
compressed air source so eliminating the need for high pressure gas storage and disruption due to bottle changes and subsequent re-
calibrations.
The inlet compressed air passes through a 1.0 micron filter to remove any particulate and then over a heated platinum catalsyst. This catalytic
action produces an ultra pure air stream with a residual hydrocarbon concentration (as methane) of less than 0.1 ppm. The gas exits the catalyst
unit, and is then cooled, via a cooling coil. Finally, the air passes through a 0.01 micron filter to remove any particulate and water, which may be
generated during the hydrocarbon removal phase.

2.6 Locating the Equipment
2.6.1 Environment
The equipment should be located indoors in an environment that protects it from direct sunlight, moisture, and dust. Changes in temperature,
humidity, and airborne pollution will affect the environment in which the equipment is operating and consequently may impair the safety and
operation.
It is the customers' responsibility to ensure that the environmental conditions specified in table 2.1 are maintained.
2.6.2 Space Requirements
The equipment should be mounted on a flat surface, capable of withstanding the weight of the equipment and all ancillary parts. A minimum
clearance of 150mm (5.9in) should be provided on all sides of the generator for air flow. Additional space should be provided so that the
generator can be moved to allow unrestricted access to the generator during servicing and maintenance.
Do Not block the side vents or the fans located on the rear panel of the generator.
Do Not position the equipment so that it is difficult to operate or disconnect from the electrical supply.
2.6.3 Ventilation Requirements
Other than providing adequate space for airflow, there are no specific ventilation requirements for this generator.
2.6.4 Air Inlet Quality
The air inlet quality specified for this generator is ISO 8573-1:2010 class 2.2.1.
ISO 8573-1:2010 is an international standard that specifies the purity classes of compressed air with respect to solid particulates, water and oil.
ISO 8573-1:2010 class 2.2.1 equates to the following:
Class 2 (Solid Particulate)
In each cubic metre of compressed air, not more than 400,000 particles in the 0.1–0.5 micron size range are allowed.In each cubic
metre of compressed air, not more than 6,000 particles in the 0.5–1 micron size range are allowed.
In each cubic metre of compressed air, not more than 100 particles in the 1–5 micron size range are allowed.
Class 2 (Water)
A pressure dewpoint of -40oC or better is required.
No liquid is allowed.
Class 1 (Oil)
In each cubic metre of compressed air, not more than 0.01 mg of oil is allowed.
Note. This is the combined level for aerosol, liquid and vapour.
ISO 8573-1:2010 Class 2.2.1 can be achieved with the following combination of Parker Hannifin purification products:
1 General Purpose filter Grade AO
2 High efficiency filter grade AA
3 PNEUDRI Adsorption Dryer (-40oC Pressure Dewpoint)
4 ACS / OVR Adsorption Filter
5 General Purpose Dust removal Filter Grade AR
2.6.5 Electrical Supply Requirements
The equipment should be connected directly from the fused IEC 320 inlet socket to the electrical supply using the power cord supplied. The
equipment should be positioned so that it can be connected to the electrical supply without the use of an extension cord.
It is the customers responsibility to provide a fused electrical supply to the equipment (Refer to table 2.1 for the electrical specification). It is
recommended that this supply have surge protection.
Chlorinated hydrocarbon compounds and chlorofluorocarbons (or freons) will permanently contaminate the hydrocarbon catalyst module in
the Zero Air Generator. Extreme care should be taken when specifying an air supply for the generator to ensure that these compounds are not
present in the air supply nor likely to get into the compressor providing air to the generator.
The hydrocarbon catalyst module can also be contaminated by high concentrations of lead, sulphur, or phosphorus compounds, heavy
metals, and long chain polymers. Care should be taken to avoid introducing these compounds into the Zero Air Generator. Specifically,
assure that none of these compounds are stored near the inlet to the compressor supplying the system with compressed air. The intake for
the compressor should be vented to the outdoors.
The equipment is connected to protective earth (ground) through the power cord. It is essential that electrical supply is equipped with a
protective earth (ground) terminal. If an alternative power cord is used to connect the equipment to the electrical supply, ensure that it is
suitably rated for the application and contains a protective earth (Ground) conductor.

3.2 Connecting the generator
Refer to “Recommended system layout” on page 8 for the desired system configuration.
Apply eight turns of PTFE tape to the threads of the compression fittings supplied. Remove the labels covering the ports of the filters and insert
the fittings.
1 Connect the generator to the air supply through a pressure relief valve, pressure regulator and an isolation valve. Leave the valve in the
closed position at this time. The pressure relief valve should be set at 11 bar g.
2 Fit a flow control valve, non-return valve and 3 way ball valve with silencer to the outlet filter of the generator.
Connect the ball valve to the application using clean stainless steel or pre-cleaned refrigeration grade copper tubing and fittings.
The tubing and fittings should be suitable for the application and rated to at least the maximum operating pressure of the generator.
3.2.1 Electrical supply
Check the rating plate for the correct supply voltage and frequency. Select the required power cord and connect it to the switched IEC 320
socket on the generator. Connect the plug directly to the electrical supply. Do not use an extension cord.
3.2.2 Stacking the Generator
The generator may be re-configured so that the Parker Hannifin H and HMD range of hydrogen generators may be stacked safely on top of it.
To re-configure the generator, unlock the two retaining screws and remove the top service lid panel (1). Remove the two retaining screws on the
rear of the top lid panel (2). Slide the panel backwards until the nylon locating screws are free from their retaining slots and remove the panel.
Remove the two screws holding the rear bracket in place. Lift the bracket away from the assembly and store it safely along with the top cover.
Position the hydrogen generator on to the zero air generator.
Note. The rubber feet on the hydrogen generator must be positioned in the locating holes (4) on the zero air generator chassis.
Ensure that the air supply and application piping are connected to the correct ports on the rear of the generator. Failure to
observe the correct orientation could lead to excessive temperatures, burns, or fire.
Do not use plastic tubing to connect the generator to the application as this could cause contamination of the zero air.
Use PTFE on the BSPT fittings. Do not use sealing compounds as they could cause contamination of the zero air.
The upper plate is designed to withstand a maximum load of 30 kg (66lb). Do not place any objects other than the Parker Hannifin hydrogen
generator on this plate.

4 Operating the equipment
4.1 Overview of the generator
4.2 Starting the generator
1 Open the isolation valve at the generator inlet and adjust the pressure as required. Set the pressure relief valve to 11 bar g (159.5 psi g).
2 Referring to the recommended set up in section 3.1, connect a suitably rated flow meter in place of the silencer on the 3-way ball valve at
the outlet of the generator. Verify that the gas flow rate matches the flow rate specified in section 2.1 and adjust accordingly.
Note. The purity of the gas delivered by the generator will be affected if the specified flow rate is exceeded. If the application instrument
does not have an integral flow controller, it is recommended that a flow controller be installed downstream of the generator outlet (refer to
recommended system layout).
3 Check system piping and fittings for leaks and repair as required.
4 Switch the generator on using the mains “ON/OFF” switch located on the rear of the generator. The heating process will start immediately
and it should take approximately ten minutes for the catalyst to reach the set temperature.
5 Once the generator reaches the set temperature, open the isolation valve located downstream of the generator.
Note. The temperature may fluctuate up to 1% of the set temperature.
6 The application instrument is now being supplied with hydrocarbon free air.
The generator is designed to operate continually without user intervention.
4.3 Shutting down the generator
1 Referring to the recommended set up in section 3.1 of this manual, slowly close the three way isolation valve to divert the flow from the
application instrument to the silencer.
2 Switch the generator off using the mains “ON/OFF” switch, located on the rear of the generator, and leave it to cool.
3 After approximately 20 minutes close the compressed air supply isolation valve and wait until the pressure gauge on the inlet of the
generator reads 0 bar g.
The generator is now shut down and fully depressurised.

In the unlikely event that a problem occurs on the equipment, this troubleshooting guide can be used to identify the probable cause and remedy.
6.1 Fault Indicators
Under certain fault conditions the following messages may be displayed on the controller.
6.2 Hydrocarbon level is a above 0.1ppm.
Troubleshooting should only be attempted by competent personnel. All major repair, and calibration work should be
undertaken by a Parker Hannifin trained, qualified and approved engineer.
Message Possible fault / Condition Action
The controller has reverted to its default setup. Contact Parker Hannifin.
The temperature is over range. The controller configuration
does not match the thermocouple. Contact Parker Hannifin.
The temperature is under range. The controller
configuration does not match the thermocouple. Contact Parker Hannifin.
The input sensor is open circuit. Contact Parker Hannifin.
Indication Possible fault / Condition Action
Poor quality results, downstream
monitoring
