3 Roof Attachment Installation (continued)

Wave roof attachment #SRM20014 & #SRM20015

The wave roof attachment is for parallel and inclined mounting on corrugated cement roofs. The wave roof attachment is screwed to the load-bearing wooden frame using mounting screws and then sealed with caulk. The horizontal bars are then screwed to the angle bracket that has been bolted to the wave roof attachment.

Install wave roof attachment

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 or 3C on page 11.

￿CAUTION

• Various sizes: Profile 5 corrugations per meter; profile 8 corrugations per meter.

The wood screws must be screwed into a member capable of bearing the required static load (generally rafters). Longer wood screws are necessary if the roof construction is higher (e.g. roof insulation).

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.

Using the wave roof attachment as a template, place the

 

wave roof attachment on the roof and pre-drill a 6 mm

 

hole as shown in FIG. 3-35.

5.

Caulk (field supplied) inside the 6 mm hole pre-drilled

 

in Step 4 (FIG. 3-35).

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. 3-34).

6.Place the wave roof attachment, angle bracket and washer over the 6 mm hole on the roof (FIG. 3-36). Insert the screw through the washer and angle bracket into the 6 mm hole securing the wave roof attachment to the roof (caulk around screws before tightening) (FIG. 3-35).
