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.

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 aw
ay 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.
