FRONT MOUNTING BRACKET MUST BE INSTALLED TO A
STRUCTURAL SUPPORT (STUD) ON THE HEADER WALL.
FAILURE TO DO SO COULD CAUSE SENSING SYSTEM TO
MALFUNCTION, RESULTING IN ENTRAPMENT, INJURY OR
DEATH. REINFORCE HEADER IF NECESSARY USING A
2 x 6 AND LAG SCREWS (NOT PROVIDED).
WARNING
STEP 1:
Mounting the Front Bracket — Sectional
Doors and One-Piece Doors with Track: Mark a
vertical centerline on the header above the door. By
manually raising the door, determine the high arc of the
door’s travel (see illustrations on page 4 ) and using a
level, transfer this measurement to the header (see
illustration at left). Draw a horizontal line, crossing the
previously drawn centerline, at this point. Install the
Front Mounting Bracket securely with the lag screws as
illustrated below. If necessary, reinforce the header with
steel angle iron or wood to ensure a secure mount.
Mount the Front Mounting Bracket securely with lag screws as
shown in figure below. If necessary, reinforce the header with
steel angle iron or wood to ensure a secure mount.
NOTE: Since the opener will be secured permanently
in this position, open and close the door a few times to
be sure the door does not rub on the Tee Rail and that
you have allowed the proper clearances before
proceeding. STEP 4:
Mount Power
Head to Ceiling: Since
there is such variety in
ceiling structures, all the
mounting possibilities for
the Power Unit cannot be
illustrated here. The
main concern is
mounting the Power Unit
securely to the ceiling
joists for operational strength, rigidity and safety.
Although there are a series of mounting slots provided
on the power unit, try to secure the hanger angle in
the slots closest to the front. Mounting may usually
be accomplished using standard 1-1/4“ perforated steel
angle available at most hardware stores. If in doubt

STEP 2
: Raise the Tee Rail so that the Front Idler
Bracket and Front Mounting Bracket align. Insert bolt
and tighten nut loosely for now. Later in the
installation, this nut must be tightened securely.
STEP 3 —
Sectional
Doors and One Piece
Doors with Track: Raise
the Opener and rest the
Power Unit on a ladder or
other sturdy support. Open the door to the full open position. Allow
2" of space between the Tee Rail and the top section of the door (as
shown in the below left illustration).
