Hang The Operator - Chamberlain ATS2113X 1/2 HP Installation Manual

INSTALLATION STEP 5

Hang the Operator

Two representative installations are shown. Yours may be
different. Hanging brackets (not provided) should be angled
(Figure 1) to provide rigid support. On fi nished ceilings
(Figure 2), attach a sturdy metal bracket to structural supports
before installing the operator. 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"-9x1-5/8" lag screws.
5. Fasten the operator 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 operator at this time.
