of collectors upon a flat roof apply to wall
mounting, except for the following:
1. If multiple wall-mounting frames are
being set up next to one another, use frame
connector (splice) kits (SFC001) to join them.
Line up the mounting supports with a string
so that the mounting frames will be aligned
properly.
2. Connect the wall mounting supports
to the wall in a suitable manner, using
the holes in support riser (SE60-110) ,
then tighten all bolts and screws. (or
support base, SE60-108, if installing as a
30° system), and transverse support (S101
collector rail).
3. Maintain the spacing between connection
points (as specified by the manufacturer).
4. Low elevation mounting configurations
may be prone to damage from falling
ice or nearby vehicles or other hazards.
Appropriate precautions should be taken to
mitigate these hazards.

installation of a 60° collector array.
5.2.3 30/60° Mounting on the
Ground
Procedures described above for mounting of
collectors upon a flat roof apply to ground
mounting, except for the following:
1. Installer must ensure that the mounting
foundation for the system is not subject to
movement, such as frost heaves. Therefore,
it is necessary to install footings below the
frost line in locations subject to freezing
weather. If it is not possible or practicable
to avoid movement due to frost, etc., it will
be necessary to provide a floating frame
that does not flex or warp the collectors’
mounting frames if the ground shifts or
heaves.
2. Ground mounting configurations may be
prone to damage from falling ice or nearby
vehicles or other hazards. Appropriate
precautions should be taken to mitigate
these hazards.
