• Ensure the Inlet Air Quality (ISO 8573.1:2010) is Class 1.2.1 or Class
1.5.1 when fitted with AMT integral dryer and the operating pressure
is between 87-145psig (6 -10barg)
• The inlet air temperature is between 34.7 – 104°F (1-40°C).
• Ensure all generator valves are closed prior to start up.
• Open the inlet valve
• Turn on power to the generator.
• When starting without any pressure in the system, partially open the
outlet valve 2 (see page 13) near the top of the generator control
panel, to allow the buffer vessel to fill up gradually. Once the buffer
vessel is at operating pressure, open the buffer outlet valve fully.
8.2 Start-up Procedure
During the first initial 5 cycles of operation, the outlet purity control valve (after the buffer tank) is automatically
diverted from delivering an outlet flow, to flow to atmosphere, allowing conditioning of the generator to improve
purity prior to going on-line.
Once the initial cycles have been completed, the system will start delivering N2 to the outlet to the outlet
receiver. The N2 outlet flow rate is controlled within the system to prevent the generator overflowing
excessively. It would however be advantageous to limit the flow from the generator, into the outlet receiver to
gradually build up receiver pressure, until it is at operating pressure in order to improve system start-up purity.
If at any time during normal operation the purity degrades to below the set point, the outlet will again close
and flow to atmosphere (clean up cycle) until the purity again achieves specification whereby normal outlet
delivery will resume.

Once the buffer vessel is at operating pressure, slowly open the generator outlet valve 4 (see page 13) to
allow the outlet received to pressurize slowly, Once at pressure the system is ready to deliver and the outlet
valve can now be opened.
