OPERATOR INSTALLATION
4.4. TRACK INSTALLATION
The height of operator installation depends on maximum lift of upper edge of the door leaf. After preliminary assembly
(see p. 4.3) you can start to install the track:
1. If it is necesssary to shorten the track, do it as described in the Appendix.
2. Mark a vertical line on the headroom corresponding to the horizontal door centre (fig. 1).
3. Place the lintel mounting bracket (1) in such a way that the distance from upper edge of the open door leaf to lower edge
of the track equals 10 mm min (fig. 3) and fix it to the lintel using self-tapping screws (2) (fig. 2).
4. Fasten the track (3) and the lintel mounting bracket by means of a track fixation bolt (4) (fig. 4).
5. Install a U-shaped bracket (5) on the track approximately at a distance of 2/3 L and attach it to the ceiling (fig. 5).
6. Install the track mounting brackets (6) on the track approximately at a distance of 1/3 L and attach them to the ceiling
(fig. 6).
7. Install a rod-to-leaf mounting bracket (7) in the middle of the upper aluminium profile of the door leaf and fix it using self-
tapping screws (8) (fig. 7).
8. Attach a curved arm (9) to the rod mounting bracket and fix it by means of a pin axle (10) (fig. 8). You can choose not to
install the curved arm, if 30° <
α
< 60°.
