Fig. 5.22 Inserting the next collector
> Then continue the assembly as for the first vertical
row of collectors:
– Screw down the flat collectors (¬ Fig. 5.13).
– Position the spacer and roof batten (¬ Fig. 5.14).
– Screw the spacer and roof batten down
(¬ Figs. 5.15, 5.16).
– Position the next collector (¬ Fig. 5.17).
When doing this, take care that the left hand side
of the collector slides under the brackets on the
neighbouring collector until it reaches the end
stop.
– Screw the flat collector down.
> Complete the collector row and the entire collector
array in the manner already described.
> Then make the hydraulic connections.

Whereas the assembly of the collectors takes
place in vertical rows, the hydraulic connec-
tions are always made in horizontal rows.

> Hook the next collector to the straps of
the front section (1).
> Slide the collector left to the neighbouring
collector (2). Make sure when doing this
– that the collector being fitted slides
under the clamps on the neighbouring
collector to the left as far as the end
stop.
– that pipe couplings slip and fit in the
side openings.
> Align the collector to the marks on the
front sections.
> Secure the pipe couplings with the
clips (3).
> Check the distance between adjacent col-
A
lectors (4). It must be 30mm ( 1 mm).
> Fasten the collector at the side to the roof
battens with 2 each of the supplied clamps
(¬ Table 5.1/5.3, Item 29) and the No. 2
screws (¬ Table 5.2/5.4) (cf. Fig. 5.12).
