Please read through these instructions and plan ahead accordingly. You will need at least 2 or 3 technicians to successfully accomplish this procedure. This job may require ladders, scaffold or lifts depending upon the particular circumstances and size of the Cascade itself.

1. Remove side access plates. These are at each end of the Cascade and are held in place with magnets. The original screen should be in the fully retracted position.
2. Remove roller tube dust cover which is fitted to housing using tongue & groove method.
3. Remove the screw from each end of the dust cover (see photo 3) Lift up and carefully pull cover toward screen roller to release it from the housing.
4. Use a pair of needle nose pliers to extract the large “C” clip that is securing the motor head within the round motor mount. (See photo 1)
5. Disconnect the white motor AC cable from controller or J-box
6. Remove the idler cotter pin from the idler shaft. (See photo 2)
7. The idler pin is spring loaded; to remove the roller tube you need to push the tube to the right and then angle the motor side down out of the way and then pull the whole assembly to the left off the idler pin and lower it out of the housing.
8. Back out the small Philip head screw on the motor end of the roller tube. You only need to back this screw out approx. 1/8” and not removing it completely.
9. Remove motor drive assembly from roller tube. Pull entire assembly out of the tube by hand. Install this assembly into the new roller tube assembly. 
10. Re-install the new RTAS in reverse fashion of the above steps. Make sure the idler pin is securely in position before the idler cotter pin is reinserted.
11. Re-connect motor’s power cable. Also secure the RTAS with the large “C” clip onto the motor mount bracket.

12. Operate the motor / roller to set the motor limit switches. First deploy the screen. If needed turn the “White” motor limit counter-clockwise to extend the screen to its full “Down” setting. Next, carefully raise the screen to adjust the motor’s “Yellow” limit switch for the screen’s fully retracted setting. Make sure the screen’s batten does not contact the screen roll once the screen stops at its fully retracted position. Clockwise adjustments will stop the motor short and counter-clockwise adjustments will increase the motor’s “Up” stopping position. Again use caution to avoid possible screen damage.

13. Re-install the 2 side ceiling end plate covers and roller tube dust cover. Job complete
