  roof installation – evacuated tube collectors  15

Once all of the collectors are joined together (two or 
three collector installations only), they should be correctly 
positioned so that they are evenly distributed on the bottom 
rail. Place the collector clamps on the bottom rail over the 
top of the provided holes and insert the bolts through the 
holes in the clamps and bottom rail. Place the washers 
and nuts on the bottom of the bolts and tighten with two 
spanners, firmly clamping the collectors to the bottom rail.

If installing on an iron roof, two top brackets supplied in the 
mounting kit are to be used to fix the collectors to the roof. 
Line up the top brackets with a horizontal roof strut (look for 
where the iron is fixed) and the side of the collector array. Fix 
the top brackets to the roof strut by either using an existing 
roofing screw or adding a new one.

Fix the top brackets to each side of the collector array with 
the supplied self tapping screws.

If installing on a tiled roof, two twisted straps are to be fixed 
to the roof and each side of the collector array. The twisted 
straps are to be fixed so that the twisted ends are flush with 
the sides of the collector array. It is important to determine 
which strap is for the left hand side and which one is for the 
right, before fixing the strap to the roof. Lift the tiles above 
each edge of the collector array and line up the appropriate 
top twisted strap with a roof strut or truss and each side of 
the collector array. Fix the flat end of the twisted strap to 
the roof strut or truss and place the tile back to its normal 
position. Fix the twisted end of the twisted strap to each side 
of the collector array using the self tapping screws supplied 
with the mounting kit.
