A. Fabricator and Installer for work under this Section are responsible for coordination of panel
and framing sizes and configurations with the Project requirements.
1.8 WARRANTY
A. If any part of the rooftop equipment screen fails because of a manufacturing defect within one
year from the date of substantial completion, the manufacturer will furnish without charge the
required replacement part(s). Any local transportation, related service labor or diagnostic call
charges are not included.
B. This warranty does not cover failure of your rooftop equipment screen if it is damaged by the
Owner, or if the failure is caused by improper installation. In no event shall Warrantor be liable
for incidental or consequential damages.

PART 3 - EXECUTION
3.1 EXAMINATION
A. Examine conditions under which construction activities of this section are to be performed.
B. Submit written notification to Architect if such conditions are unacceptable.
C. Beginning erection constitutes installer's acceptance of conditions.
3.2 INSTALLATION
A. Install units in accordance with the manufacturer's instructions and approved shop drawings.
Keep perimeter lines straight, plumb, and level. Provide brackets, anchors, and accessories
necessary for a complete installation.
B. Fasten structural supports to HVAC units without damaging operation of the unit.
1. Provide corner and mid-span assemblies as required by approved shop drawings so that
the panels are supported uniformly.
2. Fasten panel supports and track to structural steel frame as indicated.
C. Fastening bottom rail using bolts to permit ease of access to HVAC units.
D. Insert thermoplastic panels into structural supports, except where fixed attachment points are
indicated. Butt thermoplastic panels to adjacent panels for uniform fit. Fasten fixed panels in
accordance with the shop drawings.
E. Metal Separation: Where aluminum materials would contact dissimilar materials, insert rubber
grommets at attachment points, thus eliminating where dissimilar metals would otherwise be in
