Mounting

CAUTION

Device Malfunction Hazard.

Improper shaft coupling tightening causes device

malfunction.

Tighten shaft coupling with proper torque to prevent

damper shaft slippage.

CAUTION

Actuator Damage Hazard.

Using actuator as shaft bearing causes device

damage.

Use actuator only to supply rotational torque. Avoid any

side loads to actuator output coupling bearings.

To mount actuator, proceed as follows:

1. Place actuator over damper shaft; and hold mounting

bracket in place. See Fig. 5.

2. Mark screw holes on damper housing.

3. Remove actuator and mounting bracket.

4. Drill or center-punch holes for mounting screws (or use

no.10 self-tapping sheet metal screws).

NOTE: If necessary, use a field-fabricated steel base plate

secured with sheet metal screws.

5. Turn damper blades to desired normal (closed) position.

6. Place actuator and mounting bracket back into position

and secure bracket to damper box with sheet metal

screws.

7. Using 10 mm wrench, tighten shaft coupling securely

onto damper shaft using minimum 120 lb-in., maximum

180 lb-in. torque.

ENSURE THAT MOUNTING ASSEMBLY PREVENTS ACTUATOR
ROTATION AND ALLOWS ACTUATOR TO FLOAT ALONG
INDICATED AXIS. WHEN TOO TIGHT, THE RESULTING BINDING
CAN DAMAGE THE ACTUATOR OR REDUCE TORQUE OUTPUT.

ACCESSORY MOUNTING BRACKET IS NOT SUPPLIED WITH
THE ACTUATOR.
