Select rail location; insert straps through slots in rail
& screw to batten. For tile roof, attach strap directly
to truss and re-seat tile. Ensure panels have 8-10mm
collector slope from inlet to outlet. This slope must be
achieved to ensure correct level of thermosiphon.
TIP: For tin roof installations, double check the screws are
tightened firmly to avoid roof leaks.
Place first panel onto rail and ensure bottom of panel
is sitting flat on the rail. Ensure the 22mm panel unions
are connected to the first panel. Using two shifters, one
placed on the nut & one placed on the barrel of the
union, tighten the nut of the 22mm union to the 22mm
copper header pipe. DO NOT TWIST COPPER HEADER
PIPE AS THIS WILL CAUSE INTERNAL DAMAGE AND NOT
COVERED BY WARRANTY. Leave nut & olive on open
end for connection of the second panel.
Place second panel & ensure both panels are square.
Then gently slide both panels together and ensure
22mm copper header pipe is fully inserted into the
22mm panel union. Once both bottom and top 22mm
panel unions are fully inserted, using 2 shifters, place
one shifter on the nut & one shifter on the barrel of
the union and tighten the 22 mm nut. DO NOT TWIST
COPPER HEADER PIPE AS THIS WILL CAUSE INTERNAL
DAMAGE AND NOT COVERED BY WARRANTY.
Align panels to centre of the aluminium bottom rail
then screw the supplied 4 x Metal Self Tapping hex
head screws into the 4 x pre-drilled holes in bottom rail.
