INSTALLATION SECTION
Wear protective goggles when working overhead to protect your
eyes from injury.
Disengage all existing garage door locks to avoid damage to the
garage door.
To avoid serious personal injury from entanglement, remove all
ropes connected to the garage door before installing the opener.
It is recommended that the opener be installed 2,1m (7 feet) or more
above the floor where space permits.
Position the Header Bracket
The header bracket must be rigidly fastened to a structural
support of the garage. Reinforce the wall or ceiling with a 40 mm
(1-1/2") board if necessary. Failure to comply may result in
improper operation of safety reverse system.
You can attach the header bracket either to the header wall (1) or to
the ceiling (3). Follow the instructions which will work best for your
particular requirements.
With the door closed, mark the vertical centerline (2) of the garage
door. Extend line onto header wall above the door.
Open door to highest point of travel. Draw an intersecting horizontal
line (4) on header wall 5 cm (2") above high point to provide travel
clearance for top edge of door.

Install the Header Bracket
NOTE: Refer to vertical center and horizontal lines created in step
12 for proper placement of header bracket.
A. Wall Mount: Center the header bracket (1) on the vertical center
line (2) with the bottom edge of the header bracket on the
horizontal line (4) (with the arrow pointing toward the ceiling). Mark
all of the header bracket holes (5). Drill 4,5 mm (3/16") pilot holes
and fasten the header bracket with wood screws (3).
B. Ceiling Mount: Extend vertical center line (2) onto the ceiling.
Center the header bracket (1) on the vertical mark no more than
150 mm (6") from the wall. Make sure the arrow is pointing toward
the opener. Mark all of the header bracket holes (5). Drill 4,5 mm
(3/16") pilot holes and fasten the header bracket with wood screws
