STARTING THE GENERATOR
1 Inspect all of the system connection points and verify that they are secure.
2 With both the inlet and outlet ball valves of the bu er vessel closed, open the ball valve on the air inlet port to allow the compressed
air into the generator.
3 Switch the electrical power on to the generator and wait whilst it runs through the controller initialisation routine.
4 If the generator was in standby mode when the electrical power was removed it will default
to standby mode on completion of the initialisation routine.
5 Press to initiate the start up routine.
If the start clean up option is enabled the generator will run through the Rapid Cycle before
opening the bu er valve and the N outlet valve. e clean up cycle, which takes approximately
160 seconds, is designed to clean the CMS bed of impurities, bring the generator up to production purity more rapidly, and prevent
poor quality gas owing into the bu er. If the generator was running when the electrical power was removed (e.g. power failure) it
will automatically run through a start up cycle (if enabled) and then commence normal operation. Wait until this cycle is complete
and the menu displays “Running”. is may take several minutes for ppm generators.
6 Partially open the ball valve on the inlet to the bu er vessel to allow it to pressurise slowly. When the pressure gauge on the bu er
vessel reads within 0.5 barg (7psig) of the inlet pressure, check for leaks in the bu er vessel inlet piping and then fully open the ball
valve.
7 Open the ball valve on the outlet of the bu er vessel and check for leaks in the piping between the vessel and the generator.
8 Open the ball valve on the Nitrogen outlet.
Note: If the purity of the gas is not within speci cation it will be vented to atmosphere through a vent solenoid within the generator
and not delivered to the application. When the required purity is achieved the gas will be delivered to the application.

STOPPING THE GENERATOR
1 Close the ball valve on the N Outlet port.
2 Press to initiate the shutting down sequence.
e generator will complete the current cycle and then exhaust both beds. is may take several
minutes particularly on ppm generators.
3 When the generator is depressurised it will revert to standby mode.
