Installation into a Soft Crossing (up to Size 1000 × 800 mm)

EI90 - Using Mineral Wool Filling

1. The supporting construction opening must be prepared in a way described in the “Opening Preparation for

S-SA2 Installation” section (as per

Fig. 1, Fig. 2). Opening surfaces must be even and cleaned.

The exible wall opening must be reinforced as per the standards for plasterboard walls.

2. The opening dimensions are driven by the nominal dimensions of the damper with added clearance.

The opening will be made with dimensions W

and H

( Fig. 9).

3. Prepare mineral wool installation segments (4; with cubic weight of 150 kg/m

, thickness as opening gap).

First apply a suitable re resistive coating (5; CFS-CT {HILTI}) onto the damper at the place of its future placement,

assemble and glue the lling of the future installation with the same re resistive coating.

After the re resistive coating has dried, the damper along with the lling are ready for installation.

4. Apply the same re resistive coating (5) onto the internal surface of the wall opening. Also apply the re resistive

coating to the external surface of the lling glued to the damper surface. Immediately after applying the re

resistive coating, place the damper into the wall opening. The damper blade must be located in the supporting

structure. Then x the damper using the bendable bracket.

5. After inserting the damper into the opening and xing it using the bendable hangers and suitable screws

(3; recommended screw diameter 5,5 - e.g. DIN7981), apply the same re resistive coating (5), at least 2 mm

thick and 100 mm wide, to the opening lling and wall edges evenly from both sides. Do not apply this layer

in the place where the mechanism is located, inspection openings and manufacturer labels.

6. Before the re resistive coating dries, remove the unwanted remnants of the coating.

7. If needed, uncover and clean the damper after installation.

8. Check the damper’s functionality.
