Inline fan and motor specifications can be found under Dimensions .
The Inline fan is equipped with a variable speed motor.
Use cable gland size M25 at the junction box on the motors.
Isolation switch
In accordance with the provisions of the applicable EU Machinery Directive a chimney fan must always have
an isolation switch fitted. The isolation switch must comply with national wiring standards, and it must be
ordered separately, as it is not part of the standard Exodraft scope of delivery.
Checking and changing rotation of impeller
To check the rotation of the impeller, the rotation of the cooling
vanes at the end of the motor housing must be observed at low
rpm.
The cooling vanes can be observed through holes in the end
cover of the motor. Correct rotation direction is indicated by an
arrow on the Housing in front of the motor as illustrated.
It is possible for the fan to operate with improper rotation, cau -
sing the fan to be limited to 25-30 % of full capacity. Improper
rotation damages the motor, and causes various electrical faults
at the variable frequency converter.
Change of rotation is carried out by changing two of the wires at
the frequency converter. See wiring diagram delivered with the
frequency converter.
