Rafter anchor for roof tiles #SRM20003 & #SRM20004

The rafter anchor is used for parallel and inclined mounting on tiled roofs with a roof pitch of at least 15° and an area loading greater than 6 lb/ft2. Can be used for various types of roofing tiles.

Install rafter anchor

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

The anchors must be screwed into a support capable of bearing the required static load (generally rafters or concrete).

Complies with the requirements of DIN1055.

Roof batten height at least 1".

The gap between rafter anchor and top edge of the tile must be at

least 3-5mm. Under no circumstances may the rafter anchor be in contact with the tile (if the overall height of roof batten and tile do not match, the lower height must be packed out).

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.

Number two (2) tiles, one above the other. The upper

 

tile will be removed to install the rafter anchor.

5.

Mark the edge of the upper tile on the lower tile to

 

ensure proper alignment upon assembly.

6.

Using the rafter anchor as a template, pre-drill two (2)

 

6 mm holes, approximately 4 inches deep into the roof

 

substructure (see FIG. 3-7), perpendicular to the roof.

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. 3-6).

7.To achieve the recommended 3 - 5 mm clearance above the tile, place the spacer plate(s) (provided in the kit) between the rafter anchor and the roof substucture if necessary (FIG. 3-8).

8.Place the rafter anchor on the spacer plate (if used).

9.Place the heavy duty washers over the holes pre-drilled in Step 6.

10.Install the wood screws through the washers and rafter anchor into the roof substructure.

Note: It may be necessary to grind the upper tile to assure a better fit (FIG. 3-9).
