1. Fasten the eaves-side skirting on the mounting board (7).
2. Fasten the first and the last mounting clamps “frame” (3) of the lower row on to the rafter using two cylinder-
head screws (5x35) per clamp.
3. Line up the two mounting clamps with the chalk line and fasten it.
4. Align the other lowest row mounting clamps according to the grid plan and fasten them.
5. Test the clamps for stability.
6. Apply the channel sealing tape (4).
7. Inlay the modules.
4.4.1.1 Mounting the Modules
CAUTION
Wrong Screws!
Using the wrong screws can damage the mounting clamps and will not ensure the necessary stability.
Only use cylinder-head screws 5x35 (countersunk screw are not permissible).
CAUTION
Installing in the Wrong Direction!
Mind the direction! Start installing from the bottom up!
Due to the lateral overlapping of the individual frame pieces only lay the modules from the right to the left.
TIP
The modules can also be installed column by column, so that the roof remains accessible for the
installation of further rows.
