3 INSTALLATION
3.1 General Requirements
Select a suitable position for the collector. Ensure the section of roof to which the collector is
being installed is capable of supporting its weight and any likely wind loads.
The collector should face as close as practicably possible towards south and not be shaded
by surrounding buildings, trees or other sections of the building to which it is being installed.
The collector must be installed with the manifold at the top (not on its side) and on a section
of roof with a
tilt of between 25
0
and 60
0
to the horizontal . Table 3 shows the effect of the
tilt and orientation of the collector on performance.

The collector can be installed in 2 ways:
•
tiled roof installation (refer to Section 3.2)
•
slate roof installation (refer to Section 3.3)
3.2 Tiled Roof Installation
3.2.1 Assemble pitched roof brackets
Adjust the settings of the solar pitched roof brackets
(SPRB~) by varying the dimensions A and B to suit
the shape and thickness of the tiles. The dimensions
can be varied within the limits specified. Bolt the 3
sections of the brackets firmly together using the
fasteners supplied.
