Mounting on page 2.
1. Ensure the damper or valve shaft can
move freely through its entire range
of motion, and x 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 o
its stop approximately 5° may
provide tight damper shut-o.
3. Align the actuator and slide it onto the
shaft.
4. Leaving a gap between the actuator
and mounting surface to prevent any
binding, nger-tighten the nuts on the
V-bolt.
5. Insert the non-rotation bracket (HMO4002 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

8. If desired, use a 7/64-inch hex key
wrench to loosen and position the endstop 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 HLO4001 Crank Arm Kit (see the Data
Sheet).

Installation Guide on the

1. Clean the lines upstream from the
valve. Remove any debris larger
than 0.06" (0.015 mm).
2. Align the valve’s ow indicator
with the system ow.
3. Mount the valve so the actuator is
positioned over the valve body.
CAUTION
To prevent condensation from dripping
onto the actuator housing, mount the
valve with the actuator in the upright
position or, at most, at a 45° angle.
4. Seal valves with approved pipe
sealant.
5. Using two wrenches, secure the
valve to the pipe. Torque should
not exceed 75 ft-lb. (102 N
•m).

6. Eliminate air from the system to
keep the valves full of uid during operation.
NOTE: If the system experiences large amounts of
debris, steps should be taken to keep the
system clean.
CAUTION
Using mineral oil lubricants or other incompatible
substances in system fluids may damage EPDM
rubber seals in valves. Before using any lubricant or
additive in a water or ethylene glycol base, consult
the substance manufacturer for compatibility with
EPDM (Ethylene Propylene Diene Monomer).
