Mounting the Fixing Brackets
1
It is the installer’s responsibility to make sure appropriate fasteners are
used for mounting surface.
2
Mount all Fixing Brackets before beginning to install the rest of your Flex-
Louver system.
3
When 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
1
Rack 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
2
Loosen 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.
1
Insert 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.
2
Slide 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.
3
Install Drive Shaft onto the square shaft protruding from the gearbox.
