NOTE: This mounting section is specific
to the CEP-4703. For mounting a
CEP-4703V, see CEP-4703V Valve
Mounting on page 2 .
1. Ensure the damper or valve shaft 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
disengagement lever, rotate the actuator
to the fully closed position, and release
the lever.
NOTE: Depending on the damper-seal
design, backing the actuator off
its stop approximately 5° may
provide tight damper shut-off.
3. Align the actuator and slide it onto the
shaft.
4. Leaving a gap between the actuator
and mounting surface to prevent any
binding, finger-tighten the nuts on the
V-bolt.
5. Insert the non-rotation bracket (HMO-
4002 supplied or HMO-4001 “T” bracket
available separately) into the slot at the
base of the actuator (as shown in the
illustration).
6. Secure the non-rotation bracket with
two (2) #8 or #10 self-tapping screws.
7. Evenly tighten the V-bolt nuts 30 to 35
in-lb.
8. 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 (see the Data
Sheet ).
