1. Locate the mounting bracket so that the linkage rod
is approximately perpendicular to the face of the
damper when attached to the driven blade.

holes in the mounting bracket and into the duct or
damper frame.

IMPORTANT: All user adjustable features of the
actuator are accessible when mounted in the
bracket.

9. Secure the blade arm to the driven blade.
a. Remove the hex nut from the ball joint.
b. Insert the ball joint through the long slot in the
blade arm. A ball joint placement at the furthest
end of the slot results in a 2.56 in. (65 mm)
radius and is preferred for installations that
require a 90° actuator and damper blade
rotation.
c. Add the serrated lock washer and tighten the
ball joint hex nut using the recommended
torque of 2.3 to 2.8 N·m (20 to 25 lb·in.).
11. With the M9204 Series actuator and damper
blades in the spring return position, attach the
linkage rod to the ball joints. The recommended
torque for the ball joint set screws is 4 to 4.5 N·m
(35 to 40 lb·in.).

IMPORTANT: Do not stress the crankarm or
actuator when tightening the ball joints. Avoid
stressing the crankarm or actuator by supporting the
linkage rod.
