Fitting rail to the drive

1. Remove transport lock (X). Check if the chain is seated on the
gearwheel. If the chain has slipped off during assembly, relax the
chain, lay it and tighten again.
2. Turn around the rail (1) and completely put on the opener (3) with
the gear side (2).
3. Secure the rail on the opener with two mounting brackets (4) and
the screws (5).
This completes the assembly of the door opener.

Installation of the opener

7.1

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.
7.2

Mounting header bracket

NOTE:
The distance between the highest point above the door frame and
the rail should not exceed 50 mm (Fig. A).
Depending on the door type, the door frame lifts by a few centimetres
when the door is opened. This should be considered so that the door
does not rub on the rail later.
A. Wall fastening:
Minimum space requirement above the door: 100 mm
Mount header bracket (1) centrally on the vertical centre line (2); thereby
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 (3).
NOTE:
In case of mounting on a concrete slab / concrete header, the provided
concrete plugs (4) and screws (3) 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 (1) 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 (3).
7.3

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 (1) through the holes and secure with nut.
7.4

Hang opener

1. Fully open the door, put down door opener on the door (Fig. A).
Lay a piece of wood / cardboard on the marked spot (X).
2. The mounting bracket must be mounted so far back that the
carriage is not obstructed. The carriage can pass through below
the bracket partially, but not the door arm. Mounting at the very
back (Fig. B) is ideal.
3. Bend ceiling fixtures (1) in such a way that they lie flat against
the ceiling. Depending on how large the distance to the ceiling is,
none, one or two of the support brackets are to be mounted
(Fig. C1, C2 and C3).
4. Mark the boreholes on the ceiling. Pay attention to the same lateral
distance along the drawn centre line in each case.
5. For concrete ceilings, boreholes with 8 mm diameter are drilled into
the ceiling and dowels used. Then, the ceiling fixtures are fastened
in the ceiling with hexagon wood screws. While mounting on the
wooden ceiling: fasten only on the supporting parts of the wooden
ceiling. Drill boreholes with 4 mm diameter and use hexagon wood
screws.
6. Place mounting bracket (2) around the rail, then align to the ceiling
fixture and bolt them together.
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 (1) 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:
istance 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.
