Making up the frame
The cross braces (6) and angled bracing section (3) should be cut to the desired length.
Both sections must be fitted to the collector frame using the stainless steel M8 bolts provided. The bolt holes should
be drilled carefully to avoid scarring the powder-coated surface of the section.
The vertical parts (5) can be pulled out to the right angle of choice and bolted up with the bolts provided in the kit.
The feet should be fitted as shown in Section 3.
Notes:
The above diagram shows an ET30 frame, the ET20 is similar, without the middle bars.
Ensure there is a butanol layer between the feet and roof.
