Hang The Opener - LiftMaster SECURITY+ 1215EM FS2 Manual Del Propietário

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 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 5 mm 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 38 mm 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.

opener, fasten it SECURELY to structural supports of the
garage. Concrete anchors MUST be used if installing ANY
brackets into masonry.
