BEFORE YOU BEGIN:
1. Look at the wall or ceiling above the garage door. The door/header
bracket must be securely fastened to structural supports.
2. Do you have a finished ceiling in your garage? If so, a support
bracket and additional fastening hardware (not supplied) may be
required.
3. Depending on your door's construction, you might need a special
door arm. See your dealer.
4. Do you have an access door in addition to the garage door? If not,
Model 1702E Outside Quick Release Accessory is required.

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.
Installation of this product shall comply with ZH1/494, VDE 0700
Part 238, and VDE 0700 Part 1.
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 40mm
(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 on header wall 75mm (3") above high point to provide travel
clearance for top edge of door.
INSTALL THE HEADER BRACKET
A. Wall Mount: Center the bracket (2) on the vertical guideline (1)
with the bottom edge of the bracket on the horizontal line (6)
(with the arrow pointing toward the ceiling).
Mark either set of bracket holes (4 or 5). Do not use the holes
designated for ceiling mount. Drill 4,5mm (3/16") pilot holes and
fasten the bracket with wood screws (3).
B. Ceiling Mount: Extend vertical guideline (1) onto the ceiling.
Center the bracket (2) on the vertical mark no more than
150mm (6") from the wall. Make sure the arrow is pointing toward
the wall.
Mark holes designated for ceiling mount only (4). Drill 4,5mm (3/16")
pilot holes and fasten the bracket with wood screws (3). For concrete
ceiling mount, use concrete anchors (7) provided.
ATTACH RAIL TO HEADER BRACKET
Position opener on garage floor below the header bracket. Use
packing material to protect the cover.
Note: To enable the rail to clear sectional door springs, it may be
necessary to lift opener onto a temporary support.
The opener must either be secured to a support or held firmly in place
by another person.
Raise rail until rail brackets and header bracket come together. Join
with clevis pin (1). Insert ring fastener (2) to secure.
POSITION THE OPENER
Note: A 25mm (1") board (1) is convenient for setting an ideal door-to-
rail distance (unless headroom is not sufficient).
Raise the opener onto a stepladder. Open garage door. Place a
25mm (1") board (1) laid flat on the top section of door near the
centerline as shown. Rest the rail on the board.
If the raised door hits the trolley, pull down on the trolley release arm to
disconnect the inner and outer trolley sections. The trolley can remain
disconnected until connecting door arm to trolley is completed.
