The installer is solely
responsible for:
• Complying with all applicable
local or national building codes,
including any that may supercede
this manual;
• Ensuring that Unirac and other
products are appropriate for
the particular installations and
are designed for the installation
environment;
• Using only Unirac parts and
installer-supplied parts as specified
by Unirac (substitution of parts will
void the warranty);
• Ensuring safe installation of all
electrical aspects of the PV array.
Caution
Stainless steel hardware can seize up, a process called
galling. To significantly reduce its likelihood, (1) apply
lubricant to bolts, preferably an anti-seize lubricant,
available at auto parts stores, (2) shade hardware prior
to isntallation, and (3) avoid spinning on nuts at high
speed.
