1. UL Recognized Components for Fire/Smoke Applications.
2. Also order frame mounting kit accessories.
3. Mounted on plate for extended shaft with clevis and crank for 3/8-inch (10-mm), 7/16-inch (11-mm), or 1/2-inch (13-mm) diameter shaft. Parts for frame mounting (blade drive) included with kit.

NOTE: When the actuator is ordered with universal mounting, the mounting plate, pivot post and hardware, clevis, damper crank, rocker arm, and all screws/nuts are included. Order other frame mounting accessories as required if not supplied by damper manufacturer.

Installation

Extended Shaft Mounting – Pivot Actuator
Expected installation time: 28 minutes
Actuators: 331-3012, 331-3013, 331-3011, or 332-3011. These assemblies are designed for 90°damper rotation.

NOTE: Clevis mounts in crank radius hole No. 1 for 90° damper rotation.

1. Slip 3/4-inch (19-mm) diameter hole in the mounting plate over the damper shaft (Figure 1).
2. Slip the crank over the 3/8-inch through 1/2-inch (10-millimeter through 13-millimeter) diameter damper shaft (Figure 2).
3. Position the mounting plate and attach it to the duct with 4 screws.

Frame Mounting – Type A
Actuator and Clevis Assembly: 331-2857, 331-2858 or 331-2856.
Frame Mounting Kit: 751 for one-section damper, or 752 for two-section damper.

• Order from Arrow United Industries.

NOTE: Have manufacturer drill holes in damper frame and damper blade(s). Specific locations of holes are shown in the AP 331-3 Powers™ Controls No. 6 Pneumatic Damper Actuator Technical Instructions, (155-029P25).

One-Section Damper (Kit 751)
Expected installation time: Two hours

1. Attach damper mounting bracket to lower right-hand corner (or upper left-hand corner, if necessary) of damper section with six screws provided. For Arrow 1770 Dampers, add shim provided between brackets and bottom of frame.

2. Attach damper blade clip (included) to damper blade (Figure 4). Use the same clip location for both normally open and normally closed dampers. Put damper in its normal position, open or closed. Connect push rod to trunnion in blade clip and tighten setscrews. Connect other end of push rod to crank on drive shaft and tighten trunnion setscrew on push rod. Position crank so push rod is parallel to bracket, then tighten crank setscrews.

3. Install actuator in actuator support bracket using pivot shaft and hitch pins. Pivot shaft should be in holes about 17-1/2 inches (445 mm) from drive shaft. The actuator support bracket can also mount in the vertical position for installations where space is limited.

4. Position crank drive by actuator as follows:
   a. Normally open dampers: crank is above drive shaft.
   b. Normally closed dampers: crank is below drive shaft.

5. Connect actuator clevis to crank. Place damper in its normal position, open or closed. Stroke actuator 1/4-inch (6-millimeter) with hand pump, and then tighten crank setscrews. This will ensure a tight damper closure.

The installation is now complete.
Two-Section Damper (Kit 752)

Expected installation time: Two hours, 30 minutes

1. Follow the steps in One-Section Damper.
2. Attach Damper Blade Clip (included) to damper blade in second damper section. Repeat Step 2 in One-Section Damper. The push rod will connect to the extra crank on the drive shaft.

Frame Mounting – Type B
Expected installation time: Three hours Actuator: 331-3012 (331-3013 or 331-3011) Mounting lug: 331-569.

1. If damper frame is aluminum, light gauge sheet metal, or an unusual shape, bolt a 3/16-inch (5-millimeter) thick, flat piece of steel to the frame where the mounting lug is to attach. The mounting lug can then be welded to it.

2. Weld the mounting lug parallel and 5/16-inch (8-millimeter) from the inside edge of the damper frame and perpendicular to it (Figure 6). Weld the lug along both sides. The lug should be as close as possible to the corner of the damper frame to minimize deflection. The damper manufacturer should weld the lug.

3. If the damper frame is aluminum, light gauge sheet metal, or an unusual shape, bolt a 3/16-inch (5-millimeter) thick, flat piece of sheet metal to the frame. Then weld the mounting lug to it.

4. Attach rocker to blade in proper position for normally open or normally closed damper (Figure 6).

5. Attach mounting plate to mounting lug.
   a. Normally closed damper: attach plate to lug (Figure 7). Place pivot post in Hole 3.b. Normally open damper: attach plate to lug (Figure 8). Place pivot post in Hole 4.

6. Fasten clevis to rocker. Discard crank and other unused parts.

7. The actuator mounting plate has a tendency to pivot at the point where the lug is welded to the damper frame when the actuator strokes. It is recommended that some means be devised in the field to prevent this from happening. A threaded rod attached to the mounting plate and duct wall will normally work.

The installation is now complete.

Extended Shaft Remote Mounting (Figure 9)
Actuator: 331-2857, 331-2858, or 331-2856 Remote Mounting Kit: 331-618

1. Attach the mounting plate assembly to the mounting surface.
2. Attach the pivot post to the mounting plate assembly.
3. Slide the crank shaft into the bearing support.
4. Attach the two cranks to the crank shaft.
5. Position the actuator on the mounting plate and attach the clevis to one crank on the crank shaft.
6. To the other crank, attach a ball joint and a 3/8-inch (10-millimeter) diameter push rod (not provided) cut to the proper length.
7. Attach the remaining crank to the damper shaft and use the remaining ball joint to fasten it to the push rod.

The installation is now complete.
