Special consideration for Digital control
In this mode, the actuator is sensitive to induced electrical voltages from external sources. To prevent such interference, if the signal
on pins 4 and 3 on TB1 are from an external 24 Vac source, install a resistor 2.2kohm, 0.5W between pins 4 and 1 and another of
2.2kohms, 0.5W between pins 3 and 1 of TB1. These resistors are included.

Specification & Installation Instructions
Manually close the damper blades and positioned the
1.
actuator at 0º or 90º.
Slide the actuator onto the shaft.
2.
Tighten the nuts on the "U" bolt to the shaft with a 10mm
3.
wrench to a torque of 150 in.lb. [17 Nm].
Slide the mounting bracket under the actuator. Ensure free
4.
movement of the slot at the base of the actuator. The bracket
pin must be placed in the mid distance of the slot.
Fix the bracket to the ductwork with #8 self-tapping screws.
