Mounting
1. Ensure that the damper can move freely through
its entire range of motion. Fix any binding before
installing the actuator. Turn the damper blade to
its fully closed position.
2. Determine the needed direction of rotation and
relative positions of damper and actuator. See the
Adjustments section on the next page.
2. Pressandholdthegeardisengagementbuon
(see the Front View illustration), 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 standard
1/2"diameter(13mm)damperorvalvesha.
(Fora3/8"sha,seetheHFO-0011ShaAdaptor
section on the next page.)
4. Insertthenon-rotationbracket(HMO-1003,
supplied) into the slot at the base of the actuator
andsecurethebracketwithtwo(2)#8or#10
self-tapping screws. (See the Front View and Side
View illustrations.)
5. Leaving a gap between the actuator and
mounting surface to prevent any binding, tighten
the two 5/16-18 setscrews.

Maintenance
No routine maintenance is required. The motors
are permanently lubricated and all internal gear-
train components are oil-impregnated. Careful
installation will also ensure long term reliability and
performance.
Adjustments
The actuator is factory-set with the OPERATE
selector switch in the clockwise CW position, and
theactuatorwillrotateclockwisewitha2–10VDC
increasing control signal.
CAUTION
Do not press the gear disengagement button when
the actuator is powered, under load, or driven
against the end stops. Balance the load and remove
power to the actuator BEFORE pressing the button.
For Clockwise Rotation
1. Leave the OPERATE selector switch in the CW
position.
2. Depressthegeardisengagementbuon
and rotate the damper drive hub fully
counterclockwise to the 90 mark.
3. Determine what position the damper or valve
should be at 2 VDC input.
4. Position the damper or valve linkage to the full
open or close position as determined in step 3.
This ensures that as voltage increases and the
actuator rotates in the clockwise direction, the
damper or valve rotates in the proper direction.
5. Secure the actuator.
For Counterclockwise Rotation
1. Set the OPERATE selector switch in the CCW
position.
2. Depressthegeardisengagementbuonand
rotate the damper drive hub fully clockwise to the
0mark.
3. Determine what position the damper or valve
should be at 2 VDC input.
4. Position the damper or valve linkage to the full
open or close position as determined in step 3.
This ensures that as voltage increases and the
actuator rotates in the counterclockwise direction,
the damper or valve rotates in the proper
direction.
5. Secure the actuator.
Limit Min./Max. Travel with End Stop Screws
1. Loosen the minimum and maximum stop screws
one-half turn.
2. Slide the screws to the desired positions.
3. Tightenthestopscrews(9in-lbs.maximum).
Fail-Safe Function (MEP-5372 only)
Thefail-safeswitchontheMEP-5372isfactory-set
in the O position. Select either CW or CCW on the
three-position switch to choose the direction the
actuator will rotate when power is lost.
