3/8 Ø inch 

Use shaft insert supplied 

for any 3/8-in (8 - 10 mm) 

diameter shaft

 

5/8 Ø inch

 

NOTE: 

For all damper shafts with the exception of the 1/2-inch round shaft: 
Remove 1/2 Ø inch guide before installation.

 

 

Figure 14.  Damper Shaft Sizes. 

 

A mounting bracket is included with the actuator.  

Observe the service envelope around the actuator as shown in Figure 25. 

Detailed mounting instructions are included with each actuator.

 

Manual override 

To move the damper blades and lock the 
position with no power present: 

1.  Slide the red manual override knob 

toward the back of the actuator. 

2.  Make adjustments to the damper 

position. 

3.  Slide the red manual override knob 

toward the front of the actuator. 

Once power is restored, the actuator returns 
to automated control
