INSTALLATION SECTION

Wear protective goggles when working overhead to protect your eyes
from injury.Disengage all existing garage door locks to avoid damage to
garage door. To avoid serious personal injury from entanglement, remove
all ropes connected to garage door before installing 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 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
11 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
(3). For concrete ceiling mount, use concrete anchors (6) provided.

Clearance between highest point of travel and rail should not
exceed 50mm and can be zero when clearance between door and
ceiling is only 30mm.

Attach Rail to Header Bracket

Position opener on garage floor below the header bracket. Use packing
material to protect the cover. Raise rail until holes in the header sleeve
and holes in the header bracket align. Join with clevis pin (1). Insert
ring fastener (2) to secure.

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.

Hang Opener

Bend Hanging Brackets (1) so they are flat against ceiling. Measure
distance from Header Bracket to Ceiling Mounting Bracket Bolts. Mark
length on ceiling starting at the Header Wall, along this point is where the
unit will be mounted. Lift door to full open position, rest opener on door.
Insert Square Head Screws (A) into Rail assembly (B) approximately
120mm from end of Rail near motor unit. Slide Hanging Brackets on to
Square Head Screws and secure Brackets with Nuts (5). In this process
the Square Head Screws hook into slots on the sides of Rail by turning
90° (C). For concrete ceilings, drill 8mm pilot holes into ceiling and insert
Concrete Anchors (2). Secure Hanging Brackets to ceiling with Lag
Screws (3). For wood ceilings, drill 4mm pilot holes and secure with Lag
Screws (3).
