flat panel collectors
Collector pipe work connections
Open the fittings kit KKSSURA and check that all
components have been supplied (see components list).
Place two 1/2" male to collector compression union fittings
on the manifold pipes of the inlet and outlet of the collector
array (the inlet to the collector array will be at the bottom
and the outlet will be at the diagonally opposite corner at the
top). Tighten the nut using two spanners as before, sealing
the copper olive to the collector manifold pipes.

Place the stopper fittings from the kit onto the remaining
collector pipe work (also at diagonally opposite corners of
the collector array) and tighten as before with two spanners.

On the collector array outlet, install the two tee pieces, two
nipples, sensor pocket, 1/2" to 3/8" reducing bush, vent valve
and 1/2" female to copper union (see the diagram below).
Between the fittings use an appropriate thread sealant that
is capable of handling the high temperatures created by the
collectors. Ensure the vent valve is installed so that its vent is
pointing directly upwards, perpendicular to the ground (not
the roof).

Once all 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, line up a top strap with a
horizontal roof strut (look for where the iron has been fixed)
and the top side of the collector. Fix the top strap to the roof
strut by either using an existing roofing screw or adding a
new one.
If installing on a tiled roof, lift a tile above the collector and
line up a top strap with a roof strut or truss and the top side
of the collector. Fix the strap to the roof strut or truss and
place the tile back to its normal position (same procedure as
fixing the bottom strap).
Fix the top strap to the top side of the collector using a
supplied self tapping screw and repeat for each additional
collector (two or three collector installations only).
