2.1 Pre-Mounting Header Box Instructions
Disassemble parts for installation
Remove the cover from the assembly by gently prying with a screwdriver. Once the snaps are clear, pull the cover outwards
with minimal effort. Carefully set the cover in a location where it will not be damaged.
Power supply may be pulled into the header at the same time the header assembly is positioned. Make sure all power is
turned off before handling the supply wires. This should be done by a certified electrician and within the guidelines of the
enforced local electrical codes.
Be sure there is proper support in the wall to secure the header at the vertical jambs, and behind the header at intervals
between the vertical jambs. Secure the header box to the top of the door frame with the appropriate fasteners as indicated
below.
Remove the motor/gearbox and control board from the back plate. Make through holes on the back plate for mounting
header where appropriate.
