3.2 Commissioning the Generator

Ensure that the area is suitably ventilated during the commissioning stage as nitrogen will flow from the unterminated system piping.
It is assumed that the system is configured with isolation valves on the outlet of the generator and the inlet of the application instrument as
shown in "Recommended system layout" on page 8.
1 Ensure that the system piping is connected to the N
2 Disconnect the application instrument from the isolation valve and close the valve.
3 Turn the generator on at the power switch and wait until it goes into standby mode.
4 Press the key on the control panel to start the generator.
Note. If the gas is flowing from the N2 Out port rather than the N
5 Check the pressure gauges on the front of the generator and verify that the generator is pressurising.
6 Check the Mist–X exhaust to verify that the drain valve is discharging on a regular basis. If the drain valve is blocked the generator will not
reach purity.
7 Once satisfied that the generator is cycling correctly, slowly open the isolation valve on the outlet of the generator to pressurise the system
piping. Check for leaks and repair as required.
8 Open the isolation valve, normally connected to the application instrument, and allow the gas to flow to atmosphere.
It takes approximately 6 hours for the generator to reach the purity stated in "Technical Specification" on page 3. In addition the system
piping will need flushing for approximately 1 hour for every 10 metres of piping. Failure to do so could damage the application instrument.
9 Once the generator has reached its specified purity, and the system has been purged, the application instrument may be connected to the
system. Close the isolation valve on the outlet of the system and connect the application instrument.
MFC outlet port of the generator and the isolation valve is closed.
