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.

***Make sure the 2 set screws at both sides of a motor are loosened,
and the arm screws are aimed at the selected angle marked on
the label of the fan motor.***
***Make sure the two fan motors are in the same angle.***

11. Install fan blade sets
Secure the clockwise fan blade set to the clockwise motor with the screws,
and secure the counterclockwise fan blade set to the counterclockwise
motor with the screws.

10. Prepare installation of fan blade sets to motors
There is one clockwise motor & fan blade set and one counterclockwise motor & fan blade
set provided with the fan. The clockwise motor & fan blade set is colored black on the axle
and coupler. The counterclockwise motor & fan blade set is colored red on the axles and
couplers.
FAN HOUSING REVOLUTION:
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).
The fan housing will rotate only if the two motors are set at vertical (90 ) or oblique (45 ) levels.
