* After an initial running-in period, the differential pressure should generally settle within
the range 500Pa (50mm) to 1250Pa (125mm).
When restarting after maintenance work
, start the fan and check direction of rotation.
Run the fan for a few minutes and check filter differential pressure manometer reading, if
fitted. Reading should be less than 100 Pa (10 mm) for a new bag.
Press ”clean” button on controller and check time delay before clean starts, then duration
of clean cycle. These times should be approx. 2 minutes delay followed by 8 seconds
clean. Check than unit will re-
start after this cleaning cycle, by pressing ”start” button.
