Roof installation –
evacuated tube collectors
Fix the bottom straps into the roof struts or trusses using
appropriate screws, making sure the bottom rail is inclining
towards the proposed outlet end of the collectors.
If installing on a tiled roof, place the tiles back into their
normal positions after fixing the straps.
Preparing and fixing the collectors
Unpack each collector and check the contents against the
components list, being sure to leave the protective plastic
cover on each collector. This is important as the collector
connections will become very hot once exposed to solar
radiation and may cause a safety hazard or prevent the
installation of the pipe work to the collectors. Carefully lift
the collectors onto the roof and place them in position,
resting against the bottom rail of the collector mounting kit
already fixed to the roof.
Before the collectors are fixed to the roof and mounting kit,
they are to be connected together forming an array (two and
three collector installations only). The compression union
fittings supplied with the collectors are used to join the
collectors together.
Place the copper sleeve supports into the manifold pipes
of each collector. Slide the fittings onto one side of the
manifold pipe to be joined and then push both collectors
together. The collector manifold pipes shall be inserted as far
as possible into both sides of the compression union fitting.

Using two spanners, tighten each nut on the compression
union fitting one side at a time, with one spanner used to
brace the fitting in the middle. Tighten both sides of the
compression union fitting until the copper olives are firmly
sealed against both collector manifold pipes.
This standard roof mounting kit is not suitable for cyclone
prone regions. Refer to the warning in the Important Safety
Instructions section.
Preparing the mounting kit
Unpack the collector mounting kit(s) and check that all
components are included.
Slide the bottom straps onto the bottom rail and join the
bottom rails together using the rail joiner(s) if you are
installing two or three collectors.
Adjust the straps on the bottom rail so that they are evenly
spaced and place the bottom rail assembly on the roof in the
installation location decided. If installing on an iron roof, line
up the bottom straps to the existing roofing screws that are
fixing the iron roofing membrane to the struts.
If installing on a tiled roof lift up the tiles and line up the
bottom straps with the roof struts or trusses.
