Hang The Opener - B&D Controll-A-Door 4 Instructions Manual

INSTALLATION STEP 5

Hang the Opener

Two representative installations are shown. Yours
may be different. Hanging brackets should be angled
(Figure 1) to provide rigid support. On finished
ceilings (Figure 2), attach a sturdy metal bracket to
structural supports before installing the opener. This
bracket and fastening hardware are not provided.
1. Measure the distance from each side of the motor
unit to the structural support.
2. Cut both pieces of the hanging bracket to required
lengths.
3. Drill 5mm" pilot holes in the structural supports.
4. Attach one end of each bracket to a support with
8mm x 45mm lag screws.
5. Fasten the opener to the hanging brackets with
8mm x 20mm hex screws, lock washers and nuts.
NOTE: If vibration or noise is an issue you may
choose to use the vibration isolators instead as
shown in Figure 3.
6. Check to make sure the rail is centered over the
door (or in line with the header bracket if the
bracket is not centered above the door).
7. Remove the 25mm board. Operate the door
manually. If the door hits the rail, raise the header
bracket.
8. Grease the top and underside of the rail surface
where the trolley slides with rail grease.
NOTE: Do NOT connect power to
opener at this time.
