Do Not block the side vents or the fans located on the rear panel of the generator.
When considering the vertical clearance you must take into account the height required when the front upper access panel is in the
open position. Refer to table 3 for overall dimensions of the equipment.
Do Not position the equipment so that it is difficult to operate or disconnect from the electrical supply.
2.4.3 Ventilation Requirements
The accumulation of hydrogen can displace oxygen thereby creating an asphyxiation hazard. Always ensure that
the equipment is operated in a well-ventilated area.
2.4.4 Water Supply Requirements
Generators fitted with an automatic water fill system maintain the water level from a gravity fed fresh deionized water supply. Refer
to “Technical Specification” on page 3 for the supply requirements.
The use of any water, other than deionized water (Deionized, ASTM II, >1 MΩ, <1µS, filtered to <100µm), within this
generator will damage and reduce the lifetime of the hydrogen cell.
The generator should be connected to the supply using 1/4” PTFE tubing (1/4” PTFE supplied). Note. The automatic water fill
system is available as a factory or field fit optional extra. Contact Parker Hannifin for further details.
2.4.5 Electrical Supply Requirements
The equipment should be connected directly from the fused IEC 320 inlet socket to the electrical supply using the appropriate 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 customer’s responsibility to provide a fused electrical supply to the equipment (Refer to table 2 for the electrical
specification). It is recommended that this supply have surge protection.
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

3.2 Connecting the generator
3.2.1 Environmental filters
Remove the transit plugs from the vent ports, on the rear of the generator, and fit the environmental filters as shown in figs. 4 and 5.
Figure 4 Figure 5
3.2.2 Hydrogen outlet port
Refer to “Recommended system layout” on page 7 for the desired system configuration.
The generator should be connected to the application instrument using either high quality stainless steel tube or grade (B-280)
copper tube. Remove the compression plug from the hydrogen outlet port compression fitting. Insert the tube into the outlet port
fitting and rotate the tube nut until finger tight. Using a spanner (wrench) tighten the nut one and one-quarter (1 1/4) turns. Take note
that the hydrogen outlet port valve remains closed until unit has initialized. When cutting the tubes always use the correct tools to
allow a clean perpendicular cut. Cutting tubes will cause debris that, if not removed, may damage the downstream instrumentation.
It is recommended that all pipes are purged to remove any debris that may exist. When routing the tubes ensure that they are
adequately supported to prevent damage and leaks in the system. All components used within the system must be rated to at least
the maximum operating pressure of the equipment. Always protect the system by installing suitably rated pressure relief valves.
To prevent injury, and damage to the application instrument, the system piping will require purging for at least 15 minutes to
remove any trapped oxygen. If using a 3-way ball valve with vent line, as recommended on page 7, ensure that the valve is open to
the vent line and not to the application instrument. If a ball valve is not being used, ensure that the application instrument is not
connected to the system piping. Refer to “Commissioning the Generator” on page 11 for details on purging.
3.2.3 Drain ports
The overflow drain and the water bottle spillage drain must be permanently piped away using 1/2” and 1/4” PTFE tubing
respectively. The tube connected to the overflow drain should have a u-bend to prevent contamination of the internal water bottle.
Always check with local guidelines for disposing of deionized water.
3.2.4 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.

3.2.5 Filling the water bottle
The use of any water, other than deionized water (Deionized, ASTM II, >1 MΩ, <1µS, filtered to <100µm), within this
generator will damage and reduce the life time of the hydrogen cell.
Fill the water bottle, as shown in figure 6, using fresh deionized water to a level approximately 15mm below the upper lip of the neck
of the bottle. If the generator is powered up an audible and visual indication will be given when the correct level is reached.
Wearing suitable gloves to prevent contamination, insert the deionizer cartridge into the water bottle and fit the cap securely.
3.2.6 Water supply (generators fitted with Auto Water Fill)
The optional water fill allows the generator's water bottle to be gravity fed from a suitable deionized water supply. When the water
level falls below the mid-point, the water bottle will be replenished from the deionized water supply.
Connect the deionized water supply to the automatic water fill inlet using the adaptor provided and clean 1/4” PTFE tubing. It is
recommended that a balance line is fitted at the inlet to prevent air locks. Flush the line through to remove any trapped air. Refer to
“Technical Specification” on page 3 for water supply requirements.

3.4 Starting up the Generator
Ensure that a suitable vent line is provided during the commissioning stage as hydrogen will flow from the unterminated
system piping.
In order to guarantee the optimum efficiency of the PEM cell, this generator must be installed and running within three
months of dispatch from Parker Hannifin. Failure to do this may invalidate the warranty. The generator will perform a 60
minute (1 hour) initialization sequence when powered for the first time. This sequence, which cannot be aborted, is
necessary to guarantee the correct hydration of the cell.
1 Referring to the recommended set up (figure 3), use the 3-way ball valve to isolate the application instrument from the
system and divert the flow to the vent line.
If a 3-way ball valve has not been installed, disconnect the application instrument from the system and connect the open
ended piping to a suitable vent line
2 Connect the generator to the electrical supply and switch it on at the wall socket. Turn the generator on at the power
switch (located on the rear of the generator) and wait.
The generator will perform a system check during which time the water bottle indicators will illuminate white then yellow,
the system check LED will flash, and the software version number, generator serial number and the company banner will
be displayed on the LCD.
On completion the generator will warm up and the display will show “Initializing”. Once warm up is complete the unit will
revert to the default menu as shown in figure 10.
Note: Upon first use, the generator may appear to stop building pressure while the separation chamber fills with water.
Should this happen, restart the generator.
3 The internal pressure (“ACT” pressure) of the generator will build up to the required operating pressure (“SET” pressure).
To achieve the required pressure at the process instrument, it is recommended that the set pressure of the generator be
10 psig above the required pressure (i.e. to achieve 50 psig at the instrument, set pressure of the generator should be 60
psig). Doing so will negate fluctuations in pressure due to the process and pressure drop within the process piping.
4 Once the required pressure is reached, the outlet valve of the generator will be opened, as indicated by “ LOAD ” on the
display. At this time, the hydrogen outlet port valve must be opened and hydrogen will flow through the system piping and
out through the atmospheric vent line.
5 Close the 3-way ball valve to pressurize the system piping. Check for leaks and repair as required.
6 Open the 3-way ball valve to divert the flow to the application instrument.
During start-up, the generator may revert to the last error mode it experienced. If this occurs press .
When the error is cleared, the generator will continue with the start up procedure. If the error cannot be cleared by this
method follow the fault finding procedure in section 6 of this user guide.
If the pressure envelope of the system has been breached it will be necessary to run through this procedure when starting
the generator.

4.2 Starting the equipment
Connect the generator to electrical supply and switch it on at the wall socket. Turn the generator on ( I ) at the power switch (located
on the rear of the generator) and wait.
The generator will perform a system check during which time the water bottle indicators will illuminate white then yellow, the system
check LED will flash, and the software version number, generator serial number and the company banner will be displayed on the
LCD.
Upon completion, the generator will enter INITIALIZING mode while the purifier is heating. Once complete it will revert to the default
menu as shown in figure 10.
Note: Upon first use the generator may appear to stop building pressure while the separation chamber fills with water. Should this
happen, restart the generator. The internal pressure (“ACT” pressure) of the generator will build up to the required operating
pressure (“SET” pressure). Once the required pressure is reached, the outlet valve of the generator will be opened, as indicated by
“LOAD ” on the display shown in figure 9, and hydrogen will be supplied to the application instrument.
Figure 9
If the generator is being powered for the first time, it will take approximately 48 hours for the generator to reach
the purity specified.
During start-up the generator may revert to the last error mode it experienced. If this occurs press . When the error is cleared
the generator will continue with the startup procedure. If the error cannot be cleared by this method follow the fault finding procedure
in section 6 of this user guide.

4.3 Operating Menus
There are 8 menus used by the generator to display and access operational parameters and data. These can be accessed from the
default menu by sequentially pressing on the control panel. These menus are shown in table 10.
Table 10
4.3.1 Default Menu
The default menu displays the following data:
Figure 10
SET - The outlet pressure required by the application.
The required outlet pressure can be adjusted up and down using the and keys respectively.
ACT - Current actual internal / outlet pressure of the generator.
LOAD X/ -Indicates the status of the generator outlet valve. “X” - Outlet is closed, “ “- Outlet is open.
100% - The shaded blocks indicate the rate of hydrogen production. Each block represents 20% of the
rated capacity of the generator.
During initial startup, all five blocks will be shaded indicating that the generator is building up pressure and not currently
on line. When the generator is on-line and delivering gas to the application, the number of blocks shaded will depend
upon the flow required by the application.
