For optimum performance, inclination of solar collectors should be approximately equal to 90% of the local
latitude angle. The latitudes of some Australian cities are
shown in the “Latitude of Some Australian Cities
Table” on page 19. Solar collectors may be installed at the roof angle for simplicity of installation and
appearance, but must never be flat. If the roof angle varies by 15º from the optimum angle, the solar
collectors will receive approximately 10% less total solar radiation.
The collector kit is suitable for installations with an inclination of up to 45°. Where the solar collectors are
installed at inclinations greater than 45°, a
“With Pitch” frame is necessary. Refer to your local Solar
Distributor for details.
For a solar collector installation on a roof with a pitch less than 10°, a Variable Pitch frame is required. Refer
to your local Solar Distributor for details.
For an installation of collectors on a pitched roof in a cyclonic or high wind area, a suitable With Pitch frame
is required. Refer to your local Solar Distributor for details.
The installation of Aquamax S solar collectors
on a suitable frame, subject to the frame‟s design criteria not
being exceeded:
is suitable for installation in geographic locations up to and within Wind Region D (With Pitch frame) or
up to and within Wind Region C (Variable Pitch frame), as defined in the Building Code of Australia,
Australian / New Zealand Standard AS/NZS 1170.2:2002 and the Australian Standard AS 4055-2006,
and
provides an acceptable method of installation where it is necessary to satisfy the requirements of the
Building Code of Australia and AS/NZS 3500.4 Clause 6.5.3.4 for high wind areas.
The installer must ensure the structural integrity of the building is not compromised by the solar water heater
installation and the roof structure is suitable to carry the full weight of the solar collector(s). If in doubt the
roof structure should be suitably strengthened. Consult a structural engineer.
Each solar collector and its fittings weighs approximately 45 kg when full of water.
The installation must comply with the requirements of AS/NZS 3500.4 and all local codes and regulatory
authority requirements.
