INSTALLATION
Before Installing this Product
1. Read all instructions before installing this product. Fail-
ure to follow instructions can damage the product or
cause a hazardous condition.
2. Check the ratings given in the instructions and on the
product to verify that the product is suitable for your
application.
3. Installer must be a trained and experienced service tech-
nician.
4. Install the product in an area that is easily accessible for
checkout and service.
5. After completing installation, use these instructions to
check out product operation.
Installing the Retrofit Round Damper
Select a location for the damper in the ductwork. It is
suggested that the RRD damper be at least 6 feet from the
register for quiet operation.
1.
Peel off the back of the cut-out template. Carefully align
the template with the centerline of the duct. Apply tem-
plate to the section of round ductwork where the damper
is to be installed. Ensure that the template is parallel to
the ductwork. It is suggested that the damper be installed
with the motor under a horizontal duct to reduce twist to
the duct. It may also be necessary to support the duct.
2. Drill a starter hole in the cut-out area of the template.
3. Cut out the area between the holes.
4. Slide the damper into the duct and secure it with the four
supplied self-drilling mounting screws. Be careful to
avoid over-tightening the screws as the duct may be
pulled out of round. See Fig. 3.

WIRING
Wiring the Motor Actuator
Connect the motor to the zone control panel 18 or 20 gauge
wire. The motor terminals are labeled M1 for common, M6 for
closed, and M4 for open. Connect the motor terminals to
corresponding terminals on zone control panel for each zone.
See Fig. 4–6 for hookups.
Multiple RRD dampers can be wired to one zone when wired in
parallel. See Fig. 5 for wiring multiple dampers together in a
daisy chain manner or Fig. 6 using wire nuts. See Table 1 for
the maximum number of dampers that can be connected to
each zone control panel. Note that this is the total number of
dampers connected to all the zones of a zone control panel;
the maximum dampers per zone is 14. If more than 14
dampers are on one zone, a Slave Damper Control Relay
(SDCR) must be used.
When more than the maximum number of dampers allowed
per panel are necessary, a SDCR must be used. The SDCR is
an isolation relay that is powered by a separate transformer so
that it relieves the panel of this additional load. When a SDCR
is used, the dampers of that zone may either be all connected
to the SDCR, or some dampers may be wired to the SDCR and
the remainder to that zone’s damper terminals.

ADJUSTMENTS
Manual Blade Adjustment
To verify correct range of motion, depress the manual blade
adjustment button. While this is pressed, the gears are
disengaged, allowing the blade to be manually opened or
closed by turning the damper blade shaft. See Fig. 1.
Position Indicator
The position indicator points toward the position of the damper
blade to identify if the blade is open, closed, or at an
intermediate position. A slot at the end of the damper blade
shaft also indicates blade position.
Range stops
The RRD damper motor can be adjusted to prevent complete
closure of the blade. This is useful in zone systems where it is
not possible to install a bypass damper.
To set the range stop to prevent complete closure:
1. Locate the range stop adjustment screw on the top of
the motor to the right blade shaft. This is at the extreme
counter-clockwise end of travel.
2. Using a small Phillips head screwdriver, loosen the set
screw.
3. Move the end-stop block to the new position
4. Secure the set screw.
5. Verify the new range of motion while depressing the
manual blade release button.
CHECKOUT
CAUTION
Possible Equipment Damage
Do not manually open or close the damper unless the
manual blade release button is depressed
To check out the RRD damper using 24 VAC transformer:
1. Connect 24 VAC common to the M1 (common) terminal
on the actuator.
2. Connect 24 VAC hot to the M6 terminal to close the
damper.
3. Observe the blade move clockwise and stop in the
closed position.
4. Remove the 24 VAC hot wire from the M6 terminal.
5. Connect the 24 VAC hot wire to the M4 terminal.
6. Observe the blade move counter-clockwise and stop in
the open position.
7. This verifies correct operation.
To check out the RRD damper when connected to a zone
control panel. (This assumes that the damper has been wired
correctly as shown in Fig. 4.)
1. Begin with all zone thermostats set so that they are not
calling for heat, cool, or fan.
2. To test the damper on zone 1, set the thermostat on
zone 2 to the fan “On” mode so that it calls for fan.
3. This will make the damper on zone 1 close
4. Observe damper one closing on its position indicator.
The damper will take 90 seconds to close.
5. Set zone 2 thermostat to the fan “Auto” mode so that it
is no longer calling for fan. The zone 1 damper will now
return to the open position. This completes the test of
the zone 1 damper.
6. To test the damper on zone 2, set that thermostat on
zone 1 to the fan “On” mode so that it calls for fan.
7. Observe the damper on zone 2 close.
8.
Also observe that zone 3 or others, if connected, also
close when the zone 1 thermostat is in the fan “On” mode.
9. When complete, set the zone 1 thermostat to the fan
“Auto” mode. All zones will now return to the open
position.
10. This verifies correct damper wiring and operation.

manual blade release button and manually turn the blade shaft to verify
smooth opening and closing operation.
