Center PV panel assembly and tighten mounting bolts with the 7/16” wrench (Figure 1-6). Do not
overtighten bolts.

1.4: Attach the angle adjustment boom to PV assembly.
Attach angle boom to the lower mounting rail of PV assembly approximately 4.5” from the left side of
the rail (Figure 1-7).
The bolts holding the hinge to the end of the angle boom must be loosened slightly in order to pivot the
hinge. Loosen the slide nut on the end of the hinge enough to mount it to the rail. The slide nut is
inserted into the channel opposite of the PV panels. Once in position, tighten the bolt inside the hinge
with a 3/16” hex key. Allow the angle boom to pivot freely for the time being.
