SCH Collectors Installation & Operation Manual

3 Roof Attachment Installation

Joint clamp #SRM20006

The joint clamp is only used for parallel and inclined mounting on folded-seam tin roofs with galvanized or coated sheet steel, or copper, reference the Universal Cable Securing Kit on page 19.

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.

￿CAUTION

• Not recommended for titanium-zinc sheet due to danger of cracks at low temperature.

Do not reuse any stainless steel screws as there is a risk of breakage.

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

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).
