Hang The Opener - Chamberlain Whisper Drive Security+ 182665 Owner's Manual

INSTALLATION STEP 5

Hang the Opener

Three representative installations are shown. Yours
may be different. Hanging brackets should be angled
(Figure 1) to provide rigid support. On finished
ceilings (Figure 2 and Figure 3), 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 3/16" pilot holes in the structural supports.
4. Attach one end of each bracket to a support with
5/16"-18x1-7/8" lag screws.
5. Fasten the opener to the hanging brackets with
5/16"-18x7/8" hex bolts, lock washers and nuts.
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 2x4. Operate the door manually. If the
door hits the rail, raise the header bracket.
NOTE: DO NOT connect power to opener at
this time.
