4.3 Economy Mode (Optional)
Economy mode is the function whereby the generator will detect and monitor any back pressure from the application. If the pressure
exceeds a limit for a preset time (i.e. the application requires no gas) the generator will stop cycling and turn off all valves.
When the application requires gas, the back pressure
will drop and the generator will restart, defaulting into “Rapid Cycle”.
If the Economy option has been fitted it can be enabled as follows:

From he “Standby menu” press [ ] and [ ] together.
The Economy option can enabled and disabled using the [ ] and [ ] keys.

Whilst in economy mode the generator will occasionally restart and display “Cleaning Bed”,
this will l flush the system and ensure that the
unit reaches the desired purity faster when
returned online.
4.4 Rapid Cycle
Rapid cycle is the function of flushing the system of impurities in order to allow the generator to reach desired purity faster. In this mode the
generator will not deliver gas to the application for up to 15 minutes and will activate every time the generator comes out of standby or
economy mode.
If the Rapid Cycle option has been fitted it can be enabled as follows:
