1. INITIAL DAMPER TEST - Before installing damper into the wall, check damper's closing operation. This can be achieved by placing damper into its upright installation position. By placing both hands on the drive shaft, open the damper blades by rotating the drive shaft towards you. This action simulates the override of the knee action blade locking / sealing system, which is normally done by the approved actuator to suit. Reverse this sequence to close and lock the blades. CAUTION: Do NOT disconnect the McCabe^(TM) link from its operator, or injuries could be sustained. (Models 5020-1 & 5010 only).

2. "Bricking in" Advise the builder of the dampers location and "TOP" orientation.

3. All fire dampers are clearly marked with a "TOP" sticker to verify dampers orientation. Airflow direction for this model damper is optional.

4. Damper should be laid on a 3mm-4mm thick layer of mortar to ensure a firm fit within the masonry wall. The metal expansion gap seal retains the expansion gap required for the damper to expand in the event of a fire situation.

5. NOTE: lintel beam is required above damper.

6. Complete brickwork around and over damper expansion seal filling gap between brickwork and the seal with a thin layer of mortar.

7. Ensure damper is clean of any concrete after installation.

8. Repeat Point #1. INITIAL DAMPER TEST.

9. Connect Ductwork to fire damper using approved fire rated mastic to fill recess if using raw edge connection, or apply mastic to both surfaces of the TDF/TDC flange connections. NOTE: Bolts must be of low melting point material.

10. Mount actuator to operate damper as per consultants design specifications.
