Tightening Nuts
Once correctly located, the nuts should be
hand tightened ONLY using the supplied
wrench, locking the Manifold and Bottom
Support Track in place.
DO NOT
use a
power tool or longer hand tool to tighten
the nuts as stainless steel is prone to galling
(cold welding, i.e.), if excessive friction or
over-torqueing occurs (i.e. the nuts can lock
to the shaft before they are completely
seated, if they are over-tightened). The use
of a lubricant on the threads, such as WD-
40, will also help to prevent issues.
Split washers are supplied to ensure the
stainless steel bolts do not loosen over time.
Inverted Bolts
NOTE: Some bolts are inverted with the nut
on top. This so you can see the threads and
helps prevent you from loosening the bolt
so much that the nut drops off. The bolt
head is prevented from rotating by use of
nut locks (i.e. rectangular washers), removing
the need to use a second wrench
underneath the frame and aiding a quick
and easy assembly process.
Customizing the Frame
The standard frame, together with the
adjustable angle frame kit components can
be adapted to a wide range of different
installation surfaces and situations. Any
modifications to the frame design must be
approved by a licensed engineer and done
with structural integrity in mind, particularly
in high wind areas.
Cool Tip
When drilling the Stainless Steel
always use a good quality drill bit.
Take caution when using power
tools and ‘never’ do any drilling of
the frame whilst on the roof.
Cool Tip
Any modifications to the mounting
frame must be approved for
strength and safety by a licensed
engineer before installation
