Assembly of the door opener
Important instructions for a safe installation.
Observe all assembly instructions.
Incorrect installation can cause serious injury.
Assembling the rail
The rail is largely preassembled and consists of 1,2 or 3 parts (see ill).
The carriage, push rod, release handle, the guide pulley and the lintel
bracket with belt tensioner are in the front part (A). The seating for the drive
shaft and the sprocket are in the rear part (B). Lay the front and rear rail
sections one behind the other.
Assembly of a 3-piece rail:
1. Remove cable ties that secure the belt.
2. Pull apart the two rail sections completely in order to create a gap for
the middle section (C). This rail is designed in such a way so as to
easily add the middle section. Slide the 2 connecting pieces (D) over the
seams of the rail sections up to the markings. To secure the connecting
pieces, bend the sheet metal lugs outwards with a suitable tool.
The assembly of the rail is complete.
Tighten the chain belt
Tighten the belt of the rail until the spring (1) is compressed only
by about half. The spring must compress and be able to bounce during
operation.

Fitting rail to the drive
1. Check if the belt is seated on the gear-wheel. If the belt has slipped off
during assembly, relax the belt, 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).
Optional:
To reduce the total overall length by 140 mm the drive can be rotated by
90° as shown in fig.11. This allows access and programming sideways.
Unscrew the switch and mount it to the designated second position.
Remove the rubber plug in order to seal the cable exit.
Proceed with step 3.
This completes the assembly of the door opener.

Installation of the opener
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:
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:
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).
