he exact perpendicular position of the tube support is determined with a water level and adjusted
accordingly. To this end, both locking screws at the tube support and at the sliding guide of the tube
support have to be loosened.
Then, the tube support is exactly positioned with a water level and the three locking screws are firmly
tightened again (see Fig. 12).

After the fine adjustment of the tube support, the aluminium roof tile has to be fitted in place. Observe
the following installation notes:
1. Prior to installation, check the surfaces of the adjoining roof tiles to which the aluminium tile is to
be adhered. These surfaces must be clean, dry as well as free of dust, grease and moss.
2. Position the tube support in the centre of the roofing so that the aluminium roof tile completely
replaces the original roof tile over the entire surface. The tube support must not contact any point
of the hole in the aluminium roof tile.
No pressure or stress must be applied to the aluminium roof tile. Compared with a lead tile (which
is only loosely installed (“floating”)), the aluminium roof tile is firmly attached to the roof by butyl
adhesive strips.
