3. INSTALLATION

NB
If the garage door is the sole means of access to the garage, install
an external back release device (ref. 9012961 or ref. 9012962).
The position in which the drive will be fitted must allow for safe and easy
manual release of the product.

3.1. Installation height - Fig. 5

Measure the distance "D" between the highest point of the door and the
ceiling.
• If "D" is between 35 and 200 mm, secure the assembly directly to
the ceiling.
• If "D" is greater than 200 mm, secure the assembly so that the
height "H" is between 10 and 245 mm.

3.2. Installation steps - Fig. 6 to 16

3.2.1. Mounting the lintel yoke and door yoke (Fig. 6
For maximum door heights, the motor travel can be optimised by
mounting the lintel yoke on the ceiling, with a gap of up to 200 mm
from the lintel.
3.2.2. Assembling the 2-section rail - Fig. 7
1) 2) 3) Unfold the 2 sections of the rail.
NB
Ensure that the chain or belt is not twisted.
4) Assemble the 2 sections of the rail using the sleeve.
5) Secure the assembly using the 4 mounting screws.
In the case of an attached ceiling installation, do not use the sleeve
mounting screws.
NB
The mounting screws must not penetrate the rail (do not drill).
6) Tighten the nut to tense the chain or belt. The compressed rubber must
measure between 18 and 20 mm.
3.2.3. Assembling the rail on the motor head - Fig. 8
For maximum door heights, the motor travel can be optimised by fitting
the motor head at 90°.
3.2.4. Mounting on the lintel yoke - Fig. 9
3.2.5. Mounting on the ceiling
Attached ceiling - Fig. 10
Mounting directly on the ceiling using the rail.
Mounting points can be added on the motor head.
Detachable ceiling - Fig. 11
Two options:
• mount the system on the motor head (Fig. 11 -
• mount the system on the rail (Fig. 11 -
For adjustable intermediate mounting along the rail, or mounting at a di-
mension h between 250 mm and 550 mm, use the ceiling mounting kit,
part no.: 9014462 (Fig. 11 -
3.2.6. Mounting the arm to the door and carriage (Fig. 12
NB
If the back release handle is higher than 1.80 m, it is necessary to
extend the cable to make it accessible to all users.
1) Release the carriage using the manual back release device.
2) Bring the carriage level with the door.
3) Secure the arm to the door yoke and carriage.

).
3.2.7. Setting and mounting the opening stop - Fig. 13
1) Release the carriage using the manual back release device and move
the door to the open position.
NB
During this operation, check that there is no risk that the back
release device cable will subsequently become snagged on an
element protruding from the car (for example a roof rack).
Do not open the door fully, but position it so that it does not reach its stops.
2) Insert the stop block (10) into the rail then rotate 90°.
3) Position the stop block against the carriage.
4) Tighten the mounting screw moderately.
NB
Do not tighten the mounting screw to its maximum. Excessive
tightening can damage the screw and cause the stop block to be
incorrectly secured.
3.2.8. Mounting the chain bearings - Fig. 14
For chain rails only. These bearings limit unwanted noise due to friction
between the chain and the rail.
Position each of the bearings in the first hole in the rail, outside the end
limits.
Ensure that the bearing is fully pushed in so that the positioning lug pro-
trudes past the outside of the rail.
3.2.9. Checking the tension of the chain or belt - Fig. 15
The rails are supplied pre-tensioned and checked. If necessary, adjust this
tension.
NB
The rubber or tension spring must never be completely compressed
during operation.
