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

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