approximately 5° may provide tight
damper shut-off.
3. Align the actuator and slide it onto the shaft.
4. Leaving a small gap between the actuator and
mounting surface to prevent any binding, finger-
tighten the nuts on the V-bolt.
5. Insert the provided (HMO-4002) non-rotation
bracket into the slot at the base of the actuator
and secure the non-rotation bracket with two #8
or #10 self-tapping screws.
6. Evenly tighten the V-bolt nuts (30–35 in-lb.).
7. If desired, use a 7/64-inch hex key wrench to
loosen and position the end-stop screw.
NOTE: The two holes at the top of the actuator
are NOT for use in direct-coupled
applications. (They are for remote
mounting, such as with the optional HLO-
4001 Crank Arm Kit.)
NOTE: For VAV applications with the analog
CTE-5202 thermostat, see the CTE-5202
Applications Guide . For static pressure
controller applications, see the CSP-
4702 Static Pressure (Bypass) Control
Application Guide .
The CSP-4702 mounts directly to 1/4- to 5/8-inch (6 to
16 mm) round shafts or 1/4- to 7/16-inch (6 to 11 mm)
square shafts.
1. Ensure the damper can move freely through its
entire range of motion, and fix any binding before
installing the actuator. Turn the damper blade to
its fully closed position.
2. Press (to the right) and hold the gear disengage-
ment lever (see Illustration 1), rotate the actuator
to the fully closed position, and release the lever.
NOTE: Depending on the damper-seal design,
