The DS-3153 pneumatic actuator is designed for use
with SD-1300 series dampers. All models are UL
component recognized. The DS-3153 is rated for use
on SD-1300 leakage rated dampers up to
48 x 72 inches or 24 square feet and up to 350°F
(176°C).
All models incorporate several internal and external
features that add functional flexibility:
•A 2-way swivel connection on the actuator cylinder
provides non-binding movement to compensate for
damper alignment conditions.
•All actuators have a telescoping piston rod for
easy linkage to the damper for attachment points
up to 8-3/4 inches (222 mm) away from the face of
the actuator.
•A swivel ball joint and slotted crank arm connector
are furnished for optional methods of linkage to the
damper.
•A stop screw kit is available for special applications
to limit the power stroke of the actuator when
required.
The universal mounting bracket is used for damper
positioning in two types of mountings:
•duct or wall mounting for both normally open and
normally closed dampers
•frame mounting for both normally open and
normally closed dampers
The actuator mounting must be made to the linkage
side of the damper, and the blade or blade pin linkage
should be attached to the preferred driving blade,
which is identified by a blue label.

Figure 2: SD-1300 Damper Mounting Holes
1. On the side of the damper that contains the
internal linkage, locate the blade pin to be
extended (the preferred driving blade) and
mounting holes as shown in Figure 2. The blade
pins are located six inches (152 mm) apart.
Note: On 24 inch and smaller dampers, the labeled
driving blade may be next to the bottom of the
duct. If the first (labeled) blade cannot be
used, then use the third blade.
2. Use a hole saw to cut a 1-1/4 inch (32 mm)
diameter hole in the duct over the preferred driving
blade pin.
Note: If a hole saw is used, be sure that the pilot drill
does not damage the blade pin.

3. Snap the pre-assembled blade pin extension and
clip onto the blade pin as shown in Figure 3. The
drive pin has a groove that allows the clip to lock
in place.
Note: Orient the drive pin extension so that the slot
indicates the position of the damper blade with
respect to the damper frame.

Figure 4: Bracket Positions (Duct Not Shown)
1. Slide the universal mounting bracket with bearing
over the blade pin extension and position it as it
will be mounted. Mark the position of the four
mounting holes and remove the universal
mounting bracket.
2. Using a 3/16 inch (5 mm) drill bit and drill, drill
four holes in the duct to align with the mounting
holes in the damper frame as marked.
3. Start to slide the universal mounting bracket onto
the blade pin extension.
4. Determine whether Clockwise (CW) or
Counterclockwise (CCW) damper shaft rotation is
required and position the crank arm accordingly
(above or below the blade pin extension).
Note: The DS-3153 is factory assembled for proper
linkage length with a 2-1/8 inch (54 mm) crank
arm radius for 90° rotation.
5. Slide the universal mounting bracket and crank
arm over the blade pin extension and secure the
universal mounting bracket to the damper frame
using four No. 12 x 1/2 inch self tapping pan-head
screws included with the actuator.
Note: On ducts with outside insulation, the universal
mounting bracket can be attached to the duct
with the spacers supplied and the No. 12-24 x
2 inch thread forming pan-head screws.

6. Align the actuator axis in a level position parallel to
the bracket before tightening the set screws of the
crank arm.
7. If further adjustments are required, the piston rod
may be telescoped by loosening the set screw on
the shaft extension hex nut.
8. Make sure that all linkage fasteners are secure
before making air line connections.
IMPORTANT: Copper tubing must be used
between the actuator and the
controller. The tubing must be
looped at the actuator so that
pivoting of the actuator does not
cause stress on the tubing.

this time. For right-hand CCW open dampers,
position the link above the blade centerline.
For right hand CW open dampers, position the link
below the blade centerline.

4. Rotate the damper blades to their full open
position. Make sure that the reinforcement link
does not interfere with blade rotation and mark the
position of the two holes for the drive rivets.
5. With the blades closed and the reinforcement link
out of the way, use a hammer and center punch to
provide two drill guides.
6. Using a 1/4 inch (or equivalent) bit, drill two holes
for the reinforcement link at two drill guides just
made.
7. Reposition the reinforcement link and insert two
drive rivets as shown in Figure 11. At this time,
tighten the screw installed in Step 3.
8. Hammer the pins in the rivets flush with the rivet
head to secure the link to the frame.
9. Fasten the universal mounting bracket to the side
of the duct using No. 12 AB pan-head screws.
Installing Blade Arm
1. Using a 3/16 inch bit, drill two holes for the blade
arm.
•Single-piece blades, drill out the second punch
marks from the end channel.
•Two-piece blades,
a) drill out the third set of nuggets from the
end channel for normally open right hand
and normally closed left hand
b) use the drill guides for normally closed
right hand and normally open left hand
•Airfoil blades,
a) measure 1-3/4 inches from the blade edge
and on the lines etched in the blade for
normally closed right hand and normally
open left hand.
b) measure 2-3/8 inches from the blade edge
and on the lines etched in the blade for
normally open right hand and normally
closed left hand.

Figure 14: Installing Swivel Ball Joint
1. Remove the crank arm from the ball joint swivel
and attach the ball joint swivel to the long slot of
the damper blade arm for normally closed
operation and into the short slot for normally open
operation.
2. Secure the ball joint:
a) at a 2-1/8 inch radius (position D marked on
the arm). The location of the rod connection
should be positioned as shown in Figure 14 for
standard value and extended performance
dampers.
b) at “C” position in long slot for normally closed
applications and midway between “C” and “D”
in the short slot for normally open application
on airfoil blade dampers.
3. Place the swivel head bearing onto the pivot post
and secure it to the post with an E-ring provided.
4. Loosen the set screw on the shaft (and positioner
where applicable).
5. Extend the piston rod and attach the ball joint
connector to the blade arm.
6. Fully position the damper blades and tighten all
linkage fasteners and set screws.
7. If a positioner is used, adjust the spring arm so that
the spring is just taut and will clear the blade
during operation.
IMPORTANT: For pneumatically powered
safety dampers, copper tubing
must be used between the
actuator and the controller. The
tubing must be looped at the
actuator so that pivoting of the
actuator does not cause stress
on the tubing.

heck Out Procedures
1. Supply air pressure to the actuator and operated
the damper for at least three complete cycles.
2. Verify that the damper blades open or close fully.
3. Run the actuator to close the damper. If the
blades are not fully closed, adjust the position of
the linkage rod.
4. Run the actuator to open the damper. The blades
should not rotate more than 90° or past full open.
Adjust the crank arm or blade arm radius by
repositioning the ball joint if necessary.
5. Repeat procedures as necessary.
