Fit the flexible connections after the duct work of the plant
has been guided toward the inlet and discharge of the fan.
Please consider the following points when fitting the flexible
connections:
- Install the flexible connections together with the chutes
(optional)
- Install the chutes (optional) in the direction of flow
- Never subject the flexible connections to pressure or
negative pressure
- Avoid contact with sharp points and sharp-edged
objects
- Always fit the flexible connections directly at the inlet or
the discharge of the fan
Exception: For fans featuring damper, the flexible
connection is to be fitted on the damper
- Ensure correct insertion direction of screws:
The ends of the screws must always point away from
the flexible connection, even if this results in the screw
head being on top and the nut being on the bottom
- Observe the tightening torques of the screws, refer to
Table 7-1 in chapter 7.3.2 Screw connections
- Retighten the screws after a few days of operation
NOTICE!
Flexible connections have the following functions:
- Compensation of minor misalignments
- Accommodating changes in length
- Preventing conveyance of noise and vibrations
