Centre of the garage door
Eye protection goggles should be worn for overhead work.
All available barriers / locks should be deactivated to avoid damage
to the door.
To avoid serious injuries, remove all cables and chains connected to the
door before installing the door opener. The door opener should be
mounted at a height of at least 2.10 m above the ground.
First, mark the centre line of the door (1). Draw a line to the ceiling
starting from this point.
For installation on the ceiling, draw another line to the centre of the
ceiling (2) perpendicular to the door starting from this line.
Length approx. 2.80 m.

Mounting header bracket
NOTE: Mount the rail max. 50mm above the top edge of the door.
Depending on the door type, the top edge of the door is lifted by a
few cm during opening.
A. Wall fastening:
Minimum space requirement above the door: 100 mm
Mount header bracket (15) centrally on the vertical centre line (2); there-
by its lower edge lies on the horizontal line. Mark all holes for the header
bracket. Pre-drill holes with 4.5 mm diameter and fasten the header
bracket with wood screws (12).
NOTE:
In case of mounting on a concrete slab / concrete header, the provided
concrete plugs (14) and screws (12) should be used. Drill hole size in
concrete: 8 mm.
B. Ceiling suspension:
Minimum space requirement above the door: 35 mm
Draw vertical centre line (2) further up to the ceiling and about 200 mm
along the ceiling. Attach header bracket (15) centrally on the vertical
marking up to 150 mm removed from the wall. Mark all holes for the
header bracket. Drill holes with 4.5 mm diameter and fasten the header
bracket with wood screws (12).

Attaching drive to header
It may be necessary to place the drive temporarily higher, so
that the rail does not hit the springs in multi-piece doors.
The drive must either be well supported (ladder) or held firmly
by a second person. Put drive head on garage floor under the lintel
bracket. Lift rail up till the holes of the fixing part and the holes of the
lintel bracket are aligned.
Insert screw (6) through the holes and secure with nut (7).
10
Hang opener
Fully open the door, put down door opener on the door (Fig. A).
Lay a piece of wood / cardboard on the marked spot (X).
The opener must be securely fastened to a structural support of the
garage. Three representative installations are shown (Fig. B). Yours may
be different. Hanging brackets (18) should be angled to provide
rigid support. On finished ceilings, attach support bracket(not delivered)
to a self-supporting structio-nal element before installing the opener. For
concrete ceiling mount, use concrete anchors (14) provided.
On each side of opener measure the distance from the opener to the
structural support (or ceiling). Cut both pieces of the hanging bracket to
required lengths. Flatten one end of each bracket and bend or twist to fit
the fastening angles. Do not bend at the bracket holes. Drill 4,5mm pilot
holes in the structural supports (or ceiling). Attach brackets to supports
with wood screws (12).
Lift opener and fasten to hanging brackets with screw (8) and nut (9).
Check to make sure rail is centered over the door.
Remove piece of wood / cardboard. Operate door manually.
If door hits the rail, raise header bracket.
After the installation of the garage door drive, particularly using a rail
extension, if the rail is observed to be bent up or down for more than 5
cm during the beginning or end of the travel as well as while encounter-
ing an obstacle, a central suspension must be provided by the customer.
For this, please contact the manufacturer of the garage door drive.
Pay attention to a horizontal course of the rail along the
ceiling. The distance can be adjusted by the given hole
spacing. Protruding ends of the ceiling fixture can be
reduced if necessary.

Mounting door bracket
Installation in sectional or one-piece doors:
The door bracket (16) has multiple mounting holes. Attach door bracket
top centre on the inside of the door as shown. Mark holes and screw
door bracket.
Mounting heights:
1. One-piece or sectional door with a guide rail:
distance to door top edge 0-100 mm.
2. Sectional door with two guide rails:
distance to door top edge 100-130 mm.
NOTE:
The attachment point on the door must be the frame or a stable place
on the door panel. If necessary, drill through and screw (not included)
together as shown in Fig. B.
12
Attaching door arm on the trolley
The straight door arm is already pre-assembled.
Recommended installation:
The trolley can be separated from the drive by pulling the red handle
and manually pushing towards the door. When the door is closed,
fix the curved door arm (17) on the door bracket with the bolt (10) and
secure with cotter pin (11). Connect straight and curved door arms
together flush with an overlap of 2 holes with screw (8) and secure
with nut (9). Choose the holes in such a way that the door arm
stands at an angle of about 30-40°.
NOTE:
The curved door arm can be omitted, if the door fitting has been
attached at the far upper edge of the door.
Mount the release handle of the emergency release at a
height less than1.80 m. Attach the yellow label regarding the
release of the garage door opener (sticker) on the cord of the
door handle.

Electrical connection
In order to avoid personal injury and damage to the device,
the door opener should be operated only if such an instruction
is explicitly stated in this manual. The power plug must
always be freely accessible for the purpose of disconnecting
the mains supply. Electrical installations may only be under-
taken by an authorized electrician.
14
Installation of photocells
After installing and adjusting the door opener, photocells can be
installed (terminals 2 + 3). The instructions for installation are included
in the scope of delivery of the light barrier and must be followed.The
optional photocells ensure that the door is open, or remains
open, if people, especially young children, are in the door area. By
means of the photocells, a closing door is opened or an open
door is obstructed from closing, if a person located in the door area
interrupts the sensor beam.
Photocells are particularly recommended for families with young
children.
Connecting the illuminated push button
14
(Optional accessories)
All wall-mounted switches or buttons should be installed in
sight of the door outside the door or door rail area at a
height of 1.5 metres. In addition to these switches, the
warning sign for the protection of children should be affixed.
On the back of the push button there are two screw terminals
(1 & 2). The insulation is stripped up to about 6 mm from the bell wire
(4). Pull apart wires far enough from each other so that it is possible to
connect the white/red wire to a screw terminal (1) and the white wire to
the other screw terminal (2).
Illuminated wall switch: Mount on an inner wall of the garage using the
supplied sheet metal screws (3). For dry or concrete walls, pre-drill
holes with 5 mm diameter and use dowels.
