Commissioning the Fan
Danger!
Danger of personal injury and hazard of damage to the fan.
Prior to initial commissioning of the fan, read the operation instructions carefully and check the following:
•
Installation of the equipment (mounting; potential deformations)
•
All residues of the installation work removed from within the fan and the connected ducts
•
Safety features installed
•
Tightness test carried out
•
Correct execution and correct connection to the electrical installation
•
Connection data matches data on the nameplate
Danger!
Danger of injury to eyes by installation residues or dust expelled when checking the direction of rotation.
Be sure to wear safety goggles when checking the rotation direction of the impeller.
Switch the device briefly on and then off again to check the direction of impeller rotation. The impeller must rotate in the
direction indicated by the arrow on the fan housing. Check by looking through the inspection window on the fan housing.
Danger!
Live cables and connections.
Danger of personal injury from electrical current.
Have all electrical work performed by a qualified electrician.
If the direction of rotation is wrong, interchange the two phases to set the correct direction of rotation.
As soon as you have put the fan into operation, make sure it is functioning properly; check that the impeller is not obstruc-
ted; measure the current consumption; check for vibration and noises.
Attention!
Risk of damage to the fan.
If the fan is operated outside the specified characteristic curve, there is a hazard of unstable rotation and unac
-
ceptable vibrations, which can lead to destruction of the fan.
Do not operate the fan outside the specified characteristic curve.
Do not operate the fan outside the specified characteristic curve. Improper operating characteristics can result from poor
current inflow or excessively high resistance. The fan must be operated at the specified operating point.
Fill out the enclosed commissioning record form and store it for future reference in case of warranty claims.

Operation
The operating instructions supplied by the manufacturer of the motor must be observed when operating the fan.
