Service Requirements
Servicing and/or repair of the Generator should only be undertaken by a
TECHNICALLY COMPETENT PERSON with the Generator in a safely
isolated condition.
Safe Isolation Process
To shut the system down, close the inlet air supply valve (1), BUT leave the electrical power on to
the generator. Close the Nitrogen outlet valve (4) to the application, and slowly open the bypass /
commissioning valve (3) to allow the Nitrogen product gas to vent to atmosphere. NOTE: do not
isolate the Process Tank valves (5) as this will trap pressure in the tank. For the product to be
completely safe to work on ALL pressure must be fully dissipated. Ensure ALL front panel gauges
read zero before turning off the power on the front panel and removing the mains cord from the
left hand side of the generator before proceeding. Note: Due to the nature of the Carbon Sieve it
could take considerable time for the generator to release all the trapped oxygen. The bypass
valve (3) should remain open at all times, as the CMS can release oxygen and pressure can build
again if closed.
Once service operations have been completed the generator can be re-connected to the mains
supply and the Commissioning process described in earlier sections should be repeated.
Due to the simplicity of the design and the small number of moving parts the Industrial Nitropac
Series Nitrogen Generators will have a long and trouble free life. However as with all technical
equipment it should be regularly inspected and serviced as below.
