On the collector array inlet install a 1/2” to copper union
onto the 1/2” male compression union fitting making sure to
use a thread sealant.

Place the copper sleeve support into the inlet and outlet
manifold pipes of the collector array. Install a 1/2" male
compression union fitting (supplied with the collectors) and
tighten the nut using two spanners as before, sealing the
copper olive to the collector manifold pipes.

Open the fittings kit KKSSURA and check that all
components have been supplied (see components list). Since
this kit is also used for flat panel type collectors there will be
some pieces which will not be used.
On the collector array outlet install a tee piece, 1/2" to 3/8"
reducing bush, vent valve, 1/2" nipple and 1/2" female to
copper union (see diagram below). Between the fittings
use a 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).
