CD-25R-CO2low leakage control dampers employ a sturdy round
frame, a single round blade for automatic air control, and a modulating
Belimo actuator controlled by a wall-mounted CO2sensor.
Application
The following guidelines provide basic setup and installation
instructions for the CD-25R-CO2modulating damper with the room
sensor option.
General
Check for obvious and hidden package damage after receiving. Check
to be sure that all parts of the shipment, including accessories, are in
the package. Dampers must be kept clean and dry. Indoor storage and
protection from dirt are highly recommended.
If there is a question about the condition of the damper or the
installation process, please call customer service at 817-509-2300.
Receiving and Handling
After visually inspecting the damper, store it indoors, and protect it
from sunlight, moisture, and flooding. Protect dampers from debris and
dirt accumulation. Keep all conduit plugs and actuator access covers
in place.
Proper storage of the damper intends to prevent physical damage,
material corrosion, and deterioration of organic material.
Note: It is the responsibility of the installer to verify the
structural integrity of the existing structure to support the
loads imparted by the damper.
Storage of Dampers Before Installation
Warnings
1. Do not use the actuator or axle as a lifting point.
Dont’s
1. Align the damper with the existing duct work.
2. Verify the airflow direction.
3. Install and support the damper per all applicable SMACNA
guidelines.
4. Mount the sensor in the duct within the manufacturer’s
guidelines.
5. Wire the actuator into the transformer.
6. Wire the sensor to both the actuator and transformer.
7. Move the sensor wire terminals to their proper location on the
PCB board.
8. Wire transformer into the 120V building power.
9. Restore power to the system.
10. Verify the movement of the blade after installation.
11. Follow the sensor commissioning process below.
Installation Details
1. Read the installation instructions thoroughly before installing
or servicing this equipment. Improper installation, adjustment,
service, or maintenance may lead to property damage, injury,
or death.
2. Disconnect the power supply to the damper before making
any wiring connections to prevent the danger of electrical
shock or equipment damage.
3. All wiring must comply with all applicable local and national,
electrical and safety codes. Consult local codes for further
guidance.
4. When picking where the fresh air intake is placed, be cautious
of possible contaminants or blockages. Sensor Mounting
