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.
