sheet steel, or copper, reference the Universal Cable Securing
Kit on page 19.

Unpacking and checking parts
When unpacking the system, check the model names of the
components of each system and check to be sure you have the
correct number of parts (see FIG. 3-13).
Install joint clamp
1. Determine roof type. Inspect the structural integrity of
the roof and the durability of the roof materials.
2. Determine the number of collectors needed for the
installation and the number of required roof attachments
from Table 3B and 3C on page 11.
3. Determine collector connection points (spacing).
Measure the spacing of the rafters or trusses to confirm
the dimensions and prepare for the system layout
(reference the Roof Attachment Spacing Section on
page
12).
4. Assemble joint clamp as shown in FIG. 3-14 (be sure to
loosely assemble the screws on the joint clamp
assembly).
5. Place the joint clamp assembly at the appropriate
location on the joint of the tin roof.
6. Tighten the screws on the joint clamp to 26 ft./lbs.
