top of the door. Using a 4mm Allen key, wind the bolt clockwise, causing the side of the door to rise.
- 13.3. Re-close the doors and check that they run parallel and evenly to the top and
bottom tracks. If they do not, then repeat as necessary.
- 13.4. Once you have adjusted the doors, make sure that each toe and heel plate is
tight to the glass in each door, this will prevent the doors from settling over time.
NOTE: All adjustment comes from the outer frame.
Tracks
- 14.1. To check the top and bottom tracks are parallel, open all the door leaves
completely.
- 14.2. At this point, the pins in the centre of the top guide wheel should be fairly
flush with the visible face of the guide wheel, as shown in FIG14A. Move the doors along the track
whilst monitoring the pins in the top guide wheels. If the top and bottom tracks are parallel, the
visible pin should remain the same as at the start.
- 14.3. If the visible pin decreases at any point, the top track will need
repacking to raise it up at these points.
FIG 14A - 14.4. If the visible pin increases at any point, the top track will need
repacking to lower it at these points.
NOTE: The bottom track must be well supported and level for the description
above to be correct.
