2.2 Fitting rails on roof anchors
• have ready two rails in the length required for the
number and type of collectors to be installed.
• Align the travelling screw head (Fig. 9) with the hori-
zontal rail and shift the rail onto it, or shift the screws
into the rail first and fasten to the anchors. Use serra-
ted lock washers to fit the nuts.
• Align the rails so that they lie in parallel to roof tiles.
The diagonal between the rails must be of the same
length: D1 = D2 (Fig. 10).
• Then tighten the nuts on fastening bolts.
2.3 Collector mounting
Collectors shall be covered during mounting.
Installation:
• Insert safety retaining brackets (Fig. 11) into the
bottom rail, 2 brackets per collector.
• Insert the retaining brackets into the bottom rail about
100 mm from the collector edge.
• Lay the first collector carefully on the rails and align it
in the brackets.
Collectors shall be placed on the rails with
the connection piping upwards. The distance
between the bottom edge of the collector and
of the base rail depends on the design and size
of the retaining brackets. The collector bottom
edge is by circa 75 mm lower.
• The distance between the collector edge and the end
of the bottom rail is B = 35 mm (Fig. 12).
