Preconditions
Ensure that the fan and all its components are
undamaged.
Fit the fans in such a way that there is sufficient
access for installation, troubleshooting, maintenance
and repair.
Protect against dust and moisture when installing.
Ensure that the information on the name plates (fan
and motor) matches up with the operating conditions.
A warning sign must be attached close to the air
outlet, stating that the air outlet must not be covered.
Fit the fans in such a way that there is sufficient
access for troubleshooting, maintenance and repair.
Installation positions
Always install in a horizontal position.
Deflector
Position the deflector fins so that after
fastening the jet fan to the ceiling, the air
flow is directed downwards at a 10° angle.
It may be possible to readjust the fans
afterwards depending on the structures
located in the immediate vicinity, such as
girders.
