Hang The Opener - Chamberlain Whisper Drive Security+ Manual Del Propietário

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 fi nished ceilings
(Figures 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.
