screws holding slat hooks to door. Access should be
provided to these screws during and after installation.
NOTE: This switch is not normally used when operating
screen. Motor automatically shuts off if fabric does not
close fabric door.
If adjustment allows motor to shut off too soon, it will
leave fabric door open. Adjust black limit switch clockwise
(towards +).

Check for level and plumb.
Adjust "down" limit switch slowly until roller is exposed and
wrinkle comes out, then readjust for proper drop.
