INSTRUCTIONS FATPA DIRECT DRIVE SERIES

These installation instructions assume a damper is already mounted in a duct or sleeve. Have damper blades in the fail position.

1. Drill [2] .203 inch holes in the third blade from bottom, at location shown in detail "A".

2. Attach blade drive lever to blade using [2] ¼ in. - 20 x ½ in. thread cutting screws, self drilling screws or ¼

-20 x 1¼ in. bolts.

3. Fasten actuator bracket (item 1) to the left jamb of damper frame using [2] thread cutting screws. Note: the 0.563 in. hole in the bracket (item 1) that the 6 1/2 in. jackshaft (item 5) goes through must be centered with the centerline of the blade. Snap bearing (item 9) into internal actuator bracket (item 1).

4. Snap bearing (item 9) into anti-rotation bracket (item 6) and attach the anti-rotation bracket assembly (item 6) to the internal mount bracket (item #1) using [2] thread cutting screws (item 8).

5. Slide ½ in. diameter rod (item 5) slightly through the anti rotation bracket (item 6). Install crankarm (item 3) and drive link (item 2) onto the ½ in. diameter rod (item

5) and install retaining clip (item 10) to lock drive link onto the crankarm.

6. Install 10-24 x .375 shoulder bolt (item 11) to the anti rotation bracket (item #6) using #10 Nylock nut (item

12).

7. Attach actuator (item #7) to anti-rotation bracket assembly (item 6). Tighten the actuator onto the shaft.

8. Connect drive link to blade drive lever using e-clip. With blades closed and the actuator in its fail position, position the blades in their fail position and tighten the crankarm to the 1/2 in. shaft.

9. Connect all electrical leads to the actuator. Apply power to the actuator. The damper blades should power position and return to the fail position when power is disconnected.

IMPORTANT

For actuators with a product date code before 0527 a

power break of less than two seconds can cause the actuator to spring-return 5 degrees or less and remain in place until a power break of longer duration. For actuators with a product date code of 0527 or after, a power break of any duration will cause the actuator to spring-return and be able to drive immediately when power is reapplied.
