1. INITIAL DAMPER TEST - Before installing Damper into concrete slab, check damper's closing operation. This can be achieved by placing damper into it's installation position. Hold blade stack whilst removing UL33 rated fusible link. Holding the blade stack even with both hands release blades to allow closure. After viewing proper operation gather up blade and refit the UL33 fusible link to its original position.

2. Ensure slab penetration is to the AS/NZS-1682.2 requirements.

3. Apply fire rated mastic to the slab surface that the fire damper flanges sit flush upon, to ensure an airtight seal.

4. Lower the damper into position, sitting the flanges on the fire rated mastic.

5. With the steel clamp plates provided, follow the installation diagram below. Refer to note below for clamp plate quantities.

6. With installation complete to the installation details, repeat INITIAL DAMPER TEST as described in point #1 to check the dampers blade closing performance before connecting the ductwork or grilles if required to AS4254 standards.

7. Connect ductwork to fire damper using fire resistant mastic to fill recess if using raw edge connection, or apply mastic to both surfaces of the TDF/TDC flange connections. (bolts must be of a low melting point material.)
