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 ad-
vance is necessary. A damaged roof must be
re-insulated by a specialist.
Fit the collectors to the rails in the same man-
ner as if installing on an inclined roof (see point
2.3).
Minimum distance between collector fields see Fig. 21.

5.1 - Collector connecting
For collector mounting follow the instructions in chapter
5.2. Fasten the first collector and lay the following one
next to the first one, maintaining a sufficient gap. Then
put the threaded fittings on both the upper and lower out-
lets and push the collector to the already mounted until
stop. Hold the fitting 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 fittings only
after a successful leak test.
5.2 - Collector interconnecting
Hydraulic interconnection of collectors shall be done
according to Fig. 22. Maximum of 3 collectors may be
connected with threaded fittings in a row. The connecting
pipes shall be lead the shortest way. The recommended
pipe diameters and flow rates through collector arrays
are shown in Tab. 1.
