6.7.1 Checking the gap
Before first starting the fan, check the radial gap between the intake nozzle or inlet cone and
the impeller and note its width.
Transporting the fan to its destination site does not exclude the possibility of moving the inlet
side cone in relation to the impeller. The minimum size of this gap is a prerequisite for safe fan
operation.
