Opener assembly 

1./2. Scope of supply: 

The scope of supply may differ from the shown components ac-
cording to the opener version. 

3. Required tools 

For the assembly and mounting of the opener the tools shown in 
the figure are required (not included in the scope of supply). 

4./5. Requirements for installation 

The garage door opener is suitable for the automation of spring 
balanced tilt doors and sectional doors (max. recommended di-
mensions see chapter Technical data). 
For optimal attachment of the push rod to the sectional door, a 
sectional door attachment is available as an accessory. 
For the mounting of the opener a minimum lintel height of 35 mm 
is necessary. 

6. Pre-assembly of the rail 

According to the version, the rails have to be pre-assembled first. 
First connect the rail parts with the connecting rails. Slide the rails 
together as far as it will go to the stop position. 

7. Assembly of the drive adapter 

Press the pinion into the bearing. Pay attention that the belt is not 
seized. Then attach the transport protection and push the com-
plete assembly into the rail. 

8./9. Assembly of the fastening device 

Pull the chain or belt lying in the rail towards the open rail end. 
Pay attention that the driver (a) is on the correct side of the rail. 

Then fix the idler pulley at the fastening device as shown. Pay 
attention that the square coach bolt fits correctly into the bracket of 
the idler pulley. 

Now pre-tension the chain or belt by turning the nut so far that the 
chain or belt does not sag any more. 

10. Trolley test 

Check afterwards, that the trolley can easily be moved by hand. To 
release the trolley from the chain lock, push the lever on the trolley 
and at the same time move the trolley in the rail. 
Make absolutely sure, that after this test the trolley engages on the 
driver. To perform this, move the trolley without holding the lever 
over the driver and the trolley engages automatically. 

11. Assembly of the door bracket 

The push rod components included in the KIT can be combined 
according to each different installation situation. 
If the push rod is not long enough you have got the possibility to 
extend it with the extension piece. For the installation of the opener 
on a sectional door we recommend the use of the sectional door 
angle. 
Then the push rod must be fixed on the provided door bracket. 
 

 
12. Remove the light cover 

Loosen the screw from the light cover and remove the light cover. 

13. Mount the drive head to the rail 

Attach the motor shaft of the drive head to the pinion in the rail. 
Then fix the drive head with the provided screws. 

14. Mark the middle of the door 

Measure the width of the door and mark the middle of the door at 
the lintel and on the ceiling of the garage. 

15./16. Determination of the necessary height 

The rail has to be mounted on such a height that between the 
highest door point (a) (the highest point that the door can reach 
during the movement) and the lower edge of the rail (b), a clear-
ance of at least 10-20 mm is existent. 
Pay attention, that the rail is always mounted horizontally. 

The angle 

α

 may not exceed 30°, otherwise a correct transmission 

of the force is not guaranteed. 
The distance between the lower edge of the rail and the upper 
edge of the garage door should be between 5 and 7 cm in closed 
condition. 

17./18. Mounting the lintel bracket 

Fix the provided lintel bracket to the lintel considering the deter-
mined measurements (middle of the door, height) (depending to 
the installation situation it may be necessary to replace the pro-
vided fastening screws by others. 

Attention: When drilling, cover the opener!

19. Attachment of the rail to the lintel 

Then fix the rail at the lintel bracket. 

20. Mounting of the perforated angles 

The perforated angles have to be fixed to the motor head. The 
required measurements result from the before determined installa-
tion height of the rail (make sure that the rail is mounted horizon-
tally!) 

21./22. Attachment of the opener to the ceiling 

Then fix the opener to the ceiling of the garage. Make sure, that 
the rail is aligned with the earlier marked middle of the door. 

Attention: When drilling, cover the opener!

23. Tension of the chain or belt 

Turn the nut of the tension unit so far that the spring is completely 
compressed. Then release the tension of the spring by turning the 
nut back about 1 or 2 turns. 

24. Attachment of the door bracket assembly 

Release the trolley manually and move it towards the lintel. 
Attach the door bracket firmly to the door with at least 2 screws. 

25. Insert the rubber pads 

If you have a chain drive we recommend to stick the provided self-
adhesive rubber pads to the inside of the rail in order to minimize 
the noise level. Please make sure that the rubber pads are not 
fixed in the travel path of the trolley. 

26. Installing the emergency release 

If the garage is without a second entrance, the installation of a 
emergency release set is absolutely necessary, so that in case of 
an emergency the door can be opened from outside. 
It is absolutely necessary to check the correct function of the 
emergency release before starting up the garage door opener.
