12.Installing the base fastening
1. Determine the dimensions of the whole collector array and mark the position of
the U pieces (3.1/4.1). Distance A always applies to the spacing between the
U-pieces of the first and last collectors in a collector row.
Distance B applies to the collectors in between.
The measure C can be taken from the adjoining table.
There are only two U-pieces and a supporting tube between two collectors, and
these support both the collectors.
At vertical collector installation:
A=1095 mm B = 1165 mm C = 1140 mm
At horizontal collector installation:
A=1815 mm B = 1885 mm C = 700 mm
The measures relate to the middle of the U-pieces.
If only one collector is being mounted, distance A is 1025 mm.
2. Before drilling the holes in the surface for the U-pieces (3.1/4.1), check the
spacing’s using the diagonals. Diagonals E and F must be of equal length, as must
diagonals G and H. Next, drill with the ø10 mm masonry drill bit at the marked
positions.
If drilling is not permitted on a flat roof due to the leak-tightness of the roof,
concrete slabs or a similar material must be used as a foundation.
