1.1 Implementation of fastenings
Measure the distance “
D
” between the highest point of the door and the ceiling.
D
Case 1: Motorisation against ceiling
If “
D
” is between 35 and 200 mm, secure
the assembly directly to the ceiling.
When installing, centre the assembly in
relation to the garage door.
35 < D < 200
Case 2: Motorisation not against ceiling
If “
D
” is greater than 200 mm, secure
the assembly so that the height “
H
”
*
is between 10 and 200 mm.
*
H
= distance between the bottom
of the rail and the highest point of
the door.
When installing, centre the assembly in
relation to the garage door.
D > 200
10 < H < 200
To facilitate taking dimensions on the lintel: once
“D”
has been measured,
determine
“H”
by subtracting 10 from 200 mm from
“D”
. Then mark this
value on the lintel from the ceiling. The mark indicates the lower position
of the lintel bracket.
