INSTALLATION STEP 5

Hang the Opener

Two representatLve 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. (See Accessories.)

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"-18xl-7/8" lag screws.

5.Fasten the opener to the hanging brackets with 5/16"-18x7/8" hex screws, 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.
