12. Adjust fan angle :

You can select one of three different fan angles (horizontal, vertical and oblique angles). Adjust the fan angle that you

need with the following steps:

1. Loosen the two set screws at both sides of a motor.

2. Select the angle that you need. Make sure the arm screws are aimed at the selected angle marked on the label of the

fan motor.

3. Secure the set screws tightly.

4. Repeat the above steps for the other fan motor.

FAN HOUSING REVOLUTION:

The fan housing will rotate only if the two motors are set at vertical (90 ) or oblique (45 ) levels.

NOTE: Start the fan at high speed, otherwise the housing will not start rotating immediately. That is because the

torque of the motors in low speed is not strong enough to start turning the fan housing.

At vertical level : Maximum speed of housing revolution.

At oblique level: Gentle speed of housing revolution.

At horizontal level: No housing revolution (as torques of fan motors cancel out).
