But on the side opposite the tilt control, the pivot pad is spring loaded to move in and out approximately 3/8". This movement is necessary to allow the headrail to be installed into the installation brackets.

This is the installation bracket and cover. The bracket and cover are left and right specific, and each is are labeled with an L or an R.
The semi-circular area on the bottom of the installation bracket. This is the cradle where the pivot pads on the headrail fit.
There are mounting holes on the rear, top and sides of the bracket for maximum mounting versatility.  The side holes are flashed over so that they don’t show when the louvers are outside mounted.
All installation hardware is color-coordinated. 

This is the installation bracket with the cover installed.  Look at the cradle, where the pivot pad fits. Notice that the top of the pivot pad would be under the bracket cover. The bracket cover is what holds the headrail in place and still allows it to pivot.  The cover simply slides into place after the Alouette has been placed into the brackets.  The cover must be used for every bracket.

At left is the pivot bracket, used with Bar Tab System (BTS) and Bar Cord System (BCS). The pivot bracket is installed 3" from the  bottom of the louvers.  The back of the pivot bracket is aligned with the back of the installation brackets above.

The pivot arm attaches to the pivot bracket.
This is what holds the tilt bar in a vertical plane.

Spacer blocks are used with outside mounts when necessary to add clearance to clear obstructions.  A single spacer block design works for both the installation brackets and the pivot bracket.

As with Luminette® Privacy Sheers, the spacer blocks are a snap-in design. The first spacer block is screwed to the mounting surface . . . and then the brackets or additional spacer blocks are snapped into this base spacer block.

Hold-down brackets secure the bottom rail in place when the louvers are mounted on a door or hanging in a breezy window.  The bottom rail end caps must be drilled to accommodate the pin on the hold-down brackets.

Installation Procedures

Step one is attaching the installation brackets.  With inside mounts, attach the brackets in the upper corners of the window opening.

Mounting depth is important. 
As this illustration shows, a minimum of ¾" is required to attach the bracket.  For a fully recessed installation, 33/8" is needed for CCS (cord-cord-system) systems and 35/8" is required for the BTS and BCS tilt bar systems.  Add to these minimum depths the distance needed to clear any obstructions to louver or tilt bar movement.

With outside mounts, the installation brackets must be mounted level and at the same height, positioned so that their outside edges are the ordered width apart. The ordered width of Alouette™ Light Louvers is from outside edge to outside edge of the installation brackets.

Once the brackets are mounted, simply fit the spring-loaded pivot pad into the appropriate installation bracket, compress the spring ...

. . . and fit the stationary pivot pad into its cradle.

Install the bracket covers to hold the pivot pads in place.

With CCS (cord-cord system) engage the tilt mechanism by gently pulling down the tilt cord until it reaches the end of its travel.  A slight snap will be felt when the mechanism is engaged.

With BTS and BCS systems — the tilt bar designs — mount the
pivot bracket 3" up from the bottom.

Snap the pivot arm onto the pivot bracket...

You’re done!  Now that wasn't so hard, was it?
