Installation Instructions

Mechanical Installation

adequate shaft length, slide the actuator over the shaft

with the side marked "CCW" (or the "CW" side if this is the

side with the clamp). If the shaft extends at least 1/8"

through the clamp, mount the actuator as follows. If not,

go to the Short Shaft Installation section.

3. If the clamp is not on the correct side as determined in step

#1, re-mount the clamp as follows. If it is on the correct

side, proceed to step #5. Look at the universal clamp. If

you are mounting the actuator with the "CCW" side out,

position the clamp so that the pointer section of the tab is

pointing to 0° (see Fig. C) and the spline pattern of the

clamp mates with spline of the actuator. Slip the clamp

over the spline. (Use the same procedure if the "CW" side is

out.) If your application requires a mechanical minimum

position, read the Rotation Limiting, Mechanical Minimum

Damper Position section.

4. Lock the clamp to the actuator using the retaining clip.

5. Verify that the damper is still in its full fail-safe position.

6. Slide the actuator over the shaft.

7. Position the actuator in the desired location.

8. Tighten the two nuts on the clamp using a 10mm wrench

or socket using 6-8 ft-lb of torque.

9. Slip the stud of the anti rotation strap into the slot at the

base of the actuator. The stud should be positioned

approximately 1/16 of an inch from the closed end of the

slot. Bend the strap as needed to reach the duct. Attach

the strap to the duct with #8 self tapping screws.

Short Shaft Installation

If the shaft extends at least 3/4" from the duct, follow these

steps:

1. Determine the best orientation for the universal clamp on

the back of the actuator. The best location would be where

you have the easiest access to the V bolt nuts on the

clamp.

2. Engage the clamp to the actuator as close as possible to

the determined location.

3. Lock the clamp in place using the remaining retainer clip.

4. Verify that the damper is still in its full fail-safe position.

5. Slide the actuator over the shaft.

6. Position the actuator in the desired location.

7. Tighten the two nuts on the clamp using a 10mm wrench

or socket using 6-8 ft-lb of torque.

8. Slip the stud of the anti-rotation strap into the slot at the

base of the actuator. The stud should be positioned

approximately 1/16 of an inch from the closed end of the

slot. Bend the strap as needed to reach the duct. Attach

the strap to the duct with #8 self tapping screws.

9. If damper position indication is required, use the optional

IND-AF2 pointer. See Fig. A.

Jackshaft Installation

The AF... series actuator is designed for use with jackshafts

up to 1.05" in diameter. In most applications, the AF actuator

may be mounted in the same manner as a standard damper

shaft application. If more torque is required than one AF actu-

ator can provide, a second AF actuator may be mounted to

the jackshaft using the ZG-102 multiple actuator mounting

bracket. See wiring guide for wiring details.

AF actuators which may be

used on one shaft:

Mounting:

If the actuators are mounted on

the opposed ends of the shaft,

the actuator direction must be

selected carefully. Usually, the

direction of rotation is reversed.
