Caution
1Inspect all boxes to make sure you have received the proper parts.
2This document is meant to be a general guideline. Please refer to project-
specific documentation and drawings for details.
3FlexLouver Rack Arm Systems must be level and square.
4Do not wire motors in parallel without written permission from Draper.
5It is the installer’s responsibility to make sure appropriate fasteners are
used for mounting surface.
6Take account of the standard spacing (pitch) between slats. There will be
gaps at the top and bottom of the system.
7The system is sent to site as a series of components, not as a finished
system. It is then assembled on site.
8Do not operate when snow and/or ice may be present on the sys-
tem. Operating in snow and ice conditions will cause damage to the
system.
8Please read the following installation guidelines thoroughly and fol-
low them carefully. Failure to do so may cause product to fall or
otherwise fail, and invalidates warranty.

-Drive shaft and coupler
-Louvers
Basic Steps
These are some basic steps. More details will be found in the various sec-
tions, and in documents provided with your individual order.
1Install Fixing Brackets. It is the installer’s responsibility to make sure
appropriate fasteners are used for mounting surface
2Mount the Rack Arms onto the Fixing Brackets.
Please Note: The operating strip will extend beyond the rack arm when
the Louvers are in the closed position.
3Install one Louver to ensure that all of the Slat Clips are in the same posi-
tion when the Drive Shaft is installed. See "Louver Attachment" section for
details on how to attach different Louvers to the Rack Arms.
4Install the Drive Shaft.
5Attach the rest of the Louvers.

Mounting the Fixing Brackets
1It is the installer’s responsibility to make sure appropriate fasteners are
used for mounting surface.
2Mount all Fixing Brackets before beginning to install the rest of your Flex-
Louver system.
3When installing brackets, remember that it is imperative that FlexLouver
Rack Arm Systems must be level and square. If the brackets are not prop-
erly aligned, the system may be twisted slightly, interfering with operation of
the louvers. Consider using a laser level to check for level and square
bracket placement.
Attaching Rack Arm Assemblies to the Fixing Brackets
1Rack Arm assemblies (which include the operator and Bearing Brackets
pre-mounted) mount to the Fixing Brackets with provided bolts and nuts.
The nuts slide along the grooves in the bottom of the Rack Arm assem-
blies. Install with the operator on the inside of the assembly.jik
2Loosen or tighten the nuts as necessary to make sure the Rack Arm as-
semblies are installed level and square.
Installing the Drive Shaft
Please Note: Before this step, install one Louver to ensure that all of the Slat
Clips are held in the same position when the Drive Shaft is installed.
1Insert Drive Shaft into Bearing Bracket on non-operator Rack Arm As-
sembly. The outer profile of the Drive Shaft is ridged, and can be inserted
into the Bearing Bracket in several positions. Check to make sure that the
orientation is correct to allow the Drive Shaft to be fitted to the gearbox.
2Slide Drive Shaft through the bracket and through the Bearing Brackets on
the other Rack Arm assemblies. Please note: This step may require more
than one person.
3Install Drive Shaft onto the square shaft protruding from the gearbox.

Please Note: Install one Louver to ensure that all of the Rack Arms are held in
the same position when the Drive Shaft is installed. After Drive Shaft installa-
tion is complete, finish attaching the remainder of the Louvers.

1Grasp Louver with both hands. Depending on length of Louver, this may
require more than one person.
2Place Louver's extrusion "foot" into Rack Arm groove.
3Snap the other Louver extrusion into place on the other edge of the Rack
Arm.
4Carefully slide back and forth, if necessary, to correct position.
5Repeat with other end of Louver.
6For exterior installations, tighten screw to lock the Louver onto the Slat Clip.

1Grasp Louver with both hands. Depending on length of Louver, this may
require more than one person.
2Carefully squeeze Louver to increase the arc.
3Place Louver in Rack Arm attachment points and release pressure to allow
it to expand back into shape, and into place on the Rack Arm.
4Carefully slide back and forth, if necessary, to correct position.
5Repeat at all Slat Clip positions. Please Note: This assumes that there
are only two rack arms. Often there will be more. This is applicable to
all of the louver options.

Please Note: Install one Louver to ensure that all of the Rack Arms are held in
the same position when the Drive Shaft is installed. After Drive Shaft installa-
tion is complete, finish attaching the remainder of the Louvers.
1Carefully grasp Louver with both hands. Depending on length of Louver,
this may require more than one person. It is important not to allow the
Louver to flex along its length; once a roller edge Louver has been dam-
aged, it cannot be repaired and must be replaced.
2Insert one side of the Slat clip into the rolled edge of the Louver.
3Rotate the Slat Clip far enough to allow the other side of the Slat Clip to go
into the rolled edge on the other side of the Louver.
4The Slat Clip is then rotated back until it is perpendicular to the edges of
the slat.
5For exterior installations, install Slat Retaining Spring.
Cleaning and Maintenance
Under normal circumstances, the FlexLouver Rack Arm System requires
no special maintenance or adjustments other than occasional cleaning by the
end user.
For general cleaning, use a sponge and water with a mild detergent to
wipe down the louvers when in a closed position. Following cleaning, move
the louvers to the open position to allow them to dry.
Do not use acidic or abrasive cleaning agents as they could damage
the surface of the louvers.
Caution: Do not operate when snow and/or ice may be present on the
system. Operating in snow and ice conditions will cause damage to the
system.

CAUTION: The limits on your FlexLouver Rack Arm System should be
shipped pre-set. If, however, the limits do require adjustment, be sure all
switches are in “off” position before adjusting limit switches. Always be
prepared to shut off manually when new adjustment is being tested. Do not
allow the motor to continue running once the Louvers are fully open or
closed.This might lead to damage to your system.
1Determine which direction of Louver movement corresponds with arrows on
motor.
2Operate to “open” stop position. Adjust limit by turning the proper socket to add
or subtract travel.
3Operate to “closed” position. Adjust limit by turning the proper socket to fine
tune the "closed" position.
Loosen screw, slide block until
the required amount of rota-
tion is set and then tighten to
lock block into position.
When connecting the motor to the system:
1Rotate the drive shaft until the louvers are
in the fully open position.
2Press the indicated button on the motor
and rotate the drive until it is against the
fully open block. When in the correct posi-
tion, release the button.
3Clamp the drive shaft in place.
