Important
For correct thermosiphon operation,
the collectors shall slope between
8-10mm from the inlet to the outlet.
Please see adjacent diagram.
Quick Installation Guide
For tile roof installations, double check all tiles have been re-installed and sitting correctly. Failure
to do so will result in possible water ingress to home.
Using approved lifting method, place the collector/s into position on the bottom rail. Check the panel
is in the correct position to allow the tank base to be located directly over the tile batten or metal roof
batten. Using the 22mm panel unions, connect the panels together (if more than 1 panel) and tighten
firmly.
SPECIAL CARE MUST BE TAKEN WHEN TIGHTENING UNIONS TO COPPER TO ENSURE NO TWISTING
OR DEFORMATION OF COLLECTOR COPPER HEADER PIPE OCCURS. 2 (TWO) SHIFTERS MUST BE
USED AT ALL TIMES – ONE SHIFTER ON THE BODY OF THE FITTING AND ONE SHIFTER ON THE NUT.
Ensure collector is centre of the bottom rail and once satisfied, attached the rail to collectors using the
screws supplied.
For tile roof installations, it is recommended that a suitable flashing is now installed underneath
the location of the tank.
Lift the storage tank into position and centralise its location on the top of the collector/s. Connect the
tank straps supplied to the provision on the rear of tank. For metal roof installations, roof and gutter
silicone shall be used between the strap and roof. Fix the rear tank straps the roof rafters/battens.
Using the connection fittings and pipes supplied, connect the tank and collector/s together. In areas of
frost, a freeze protection valve shall be connected via a ¾ x ½ brass hex nipple in place of the bottom
collector plug.
