10.5 Adjusting the blade angle
If the operating point of the fan has to be changed and adjustment of the blade angle is necessary, please get
in touch with the Systemair service department at all costs! Adjustment of the blade angle requires know-
ledge of the current consumption of the motor and the maximum admissible blade angle relative to the motor
installed.
11 Commissioning
DANGER! Risk of injury and risk of damage to the fan. Before commissioning, read the operating
instructions carefully and check the following:
• positioning of the device (tting, possible deformations)
• assembly residue and foreign bodies removed from fan area and connected channel
• safety devices tted
• leakage test carried out
• correct performance and correct connection to the electrical installation
• correspondence of the connection data with the information on the name plate
• Before commissioning, check the minimum air gap between the tip of the blade and the housing
once more (see Point 10.3 Assembly).
DANGER! Risk of injuries to the eyes by residue or dust being swirled out when checking the
direction of rotation. When checking the direction of rotation of the rotor, wear
protective goggles!
• If the air gap is correct, switch the device on and off briey, in order to check the direction of rotati
on of the rotor. The direction of rotation of the rotor must match up with the direction of the arrow
on the housing of the fan. You establish this by a visual check on the admission nozzle at the intake
fest or through an excisting hole in the casing.
DANGER! Live wires and connections!
Risk of injuries from electric current!
Have all electrical work done by a trained electrician only!
• If the direction of rotation is wrong, interchange two phases in order to set the correct direction of
rotation.
• As soon as you have put the fan into operation, check awless functioning (free movement of the
rotor, measurement of the current consumption, check for possible vibrations and noises).
