PRE-INSTALLATION
Important:
Tornado Electric Fans come from the factory with a product label
installed on one end of the fan shroud. Before installation check the product
label to confirm airflow direction and positive electric fan lead color.
Airflow direction will be shown with an arrow.
This fan is factory setup for PULLER applications
Changing airflow direction
To change the airflow direction from the factory setting:
1. Remove the Nut or Clip that holds the electric fan blade onto the motor
shaft.
2. Carefully remove the fan blade from the motor shaft.
Note:
This is an interference fit and requires some effort.
3. Flip the fan blade upside down and reinstall onto the motor shaft. Make
sure the roll pin on the motor shaft is aligned with the slot on the fan blade.
4. Reinstall nut or clip on motor shaft.
Important:
For Puller applications use the referenced wire colors stated on the
Product Label. For Pusher applications the two wires MUST be reversed to
change airflow direction.
