3.7.3 Ducting of fan<br />
3.7.4 Check of clearances<br />
BWA-<strong>KXE</strong>-Fetteinzelstehlager_englisch_02.doc<br />
Transport, Installation<br />
Distortions of the fan at the connections caused by<br />
the ductwork are not permitted. Distortions cause<br />
alterations, e.g. the gap at the nozzle decreases at<br />
one side which might lead to rubbing in the inlet.<br />
- Remove the transport covers from the connections.<br />
- Move the duct work to be connected to the inlet and discharge<br />
openings of the fan without causing offsets between<br />
the ducts and openings.<br />
- Connect duct and conduits to the fan free-of-load.<br />
The radial clearance within the inlet must be checked. The<br />
minimum clearance must amount to 3 mm at least.<br />

At the beginning of the gap check, take the gap width at<br />
eight different points. Then turn the impeller by 90° and<br />
again check the gap at eight different points. Repeat this<br />
process three times.<br />
