Mechanical Installation
1.
Manually close the damper blades and positioned the
actuator at 0º or 90º.
2.
Slide the actuator onto the shaft.
3.
Tighten the nuts on the “U” bolt to the shaft with a 8mm
wrench to a torque of 60 in.lb. [6,7 Nm].
4.
Slide the mounting bracket under the actuator. Ensure free
movement of the slot at the base of the actuator. The
bracket pin must be placed in the mid distance of the slot.
5.
Fix the bracket to the ductwork with #8 self-tapping screws.

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.
