EcoFoot2+ General Application Notes
Site-Specic System Design: Unirac provides drafting services on all EcoFoot2+ projects. This service produces a site-specic design package with an Engineered
Stamped Layout including detailed ballast plan and bill of materials.
Roof Type: EcoFoot2+ is designed to mount photovoltaic modules to a range of roof surfaces, including: EPDM, TPO, PVC, Mineral Cap Sheet (a.k.a. Rolled Asphalt), Tar
and Gravel.
Roof Slope Range: 0-7 degrees maximum, 3-degree limit for unattached seismic.
Wind Zone: EcoFoot2+ is designed to mount photovoltaic modules on at roof surfaces with a maximum pitch of 7 degrees in areas with extreme wind conditions.
Please contact Unirac for clarication or assistance.
Installation Requirements: EcoFoot2+ is ballasted photovoltaic racking designed as a system which requires all EcoFoot2+ components, the specic module, and
ballast placement prescribed in the PE stamped design. The absence of any of these elements in any given sub-array could present a compromised condition on the
roof. Arrays shall not be left unattended in such a state during an installation.
This install guide ofcially documents the components used and proper methods for an EcoFoot2+ installation. Bonding elements are incorporated into EcoFoot2+
components. As the system is built on the roof, components and modules are bonded together. Specic steps to ensure a bonded system are described through the
installation guide. It is the installer’s responsibility to ensure that the system is safely and properly installed, and that the system is bonded back to a nal ground
point.
When wiring the array, keep bare copper from contacting bare aluminum.
