Secure the support structure either by screwing it into
the roof, or applying a burden.
In no event the permissible roof load shall be
exceeded. Consulting a statics expert in advan-
ce is necessary. A damaged roof must be re-
-insulated by a specialist.
Fit the collectors to the rails in the same mann-
er as if installing on an inclined roof (see point
2.4).
Minimum distance between collector fi elds see Fig. 21.

5.1 - Collector connecting
For collector mounting follow the instructions in chapter
5.2. Fasten the
fi rst collector and lay the following one
next to the fi rst one, maintaining a suf fi cient gap. Then
put the threaded fi ttings on both the upper and lower
outlets and push the collector to the already mounted
one until stop. Hold the
fi tting with a spanner (Fig. 23)
to prevent turning, and tighten the nuts. Continue in the
same way with further collectors.
Put the insulation on the threaded fi ttings only
after a successful leak test.
5.2 - Collector interconnecting
Hydraulic interconnection of collectors shall be done
according to Fig. 22a. Maximum of 6 collectors may be
connected with threaded
fi ttings in a row. If there are
more than 6 collectors in a row, a compensator shall be
installed in the middle of the array. With a compensator,
max. 8 collectors in a row may be installed. The con-
necting pipes shall be lead the shortest way. The recom-
mended pipe diameters and
fl ow rates through collector
arrays are shown in Tab. 1.
