4.4. TRACK INSTALLATION
The operator suspension height is determined by the 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 required to shorten a guide, it is necessary to fulfill operations, described in Appendix 1.
2. You should mark a vertical line, corresponding to the horizontal door centre (fig. 5).
3. Y ou should place a 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 amounted to minimum 10 mm (fig. 5.2) and fix it to the lintel using self-tapping screws (2) (fig. 5.1).
4. You should fasten the track (3) and the lintel mounting bracket by means of a track fixation bolt (4) (fig. 5.3).
5. You should install a U-shaped bracket (5) on the track approximately at a distance 2/3 L and attach it to the ceiling (fig. 5.4).
6. Y ou should install track mounting brackets (6) on the track approximately at a distance 1/3 L and attach them to the
ceiling (fig. 5.5).
7. Y ou should 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. 5.6).
8. Y ou should attach a cranked rod (9) to the rod mounting bracket and fix it by means of a pin axle (10) (fig. 5.7).
It is allowed not to mount the cranked rod, if α angle is observed.
