Installation Guide
NOTE: This installation guide is for installing SSS-10xx models. For guidance in installing SSS-111x models, see the KMC Conquest Airflow Measurement System Installation Guide.
Mounting for Differential Pressure Flow
To mount the pickup tubes for differential pressure:
-
Determine the duct’s flow direction and install the pickup tubes based on the flow arrow imprint.
NOTE: The pickup tubes must be mounted with the FLOW arrow imprint pointing in the direction of the air flow. -
Cut a 7/8″ (22 mm) hole in the duct to accept the pickup tubes.
-
Attach the pickup tubes to the duct using two selftapping screws inserted through the 3/16″ (5 mm) mounting holes.
Connections
Use appropriately sized polyethylene tubing to connect the pickup tubes to the controller:
- For connecting SSS-10xx pickup tubes with CSC-3000 series, CSP-4000/5000 series, KMD-7000 series, and BAC-7000/8000/9000 series controllers, use a barb union adapter and tubing sized appropriately to the pickup tubes and controller. For aximum accuracy in the CSP-5000 series, KMD-7000 series, and BAC-7000 series controllers, the 3/8″ OD tubing between the pickup tubes and the adapter should be as short as possible, and the 1/4″ OD tubing from the adapter to the controller should be 24″ long (on both the High and the Low sides).
- OR use the equivalent SSS-101x pickup tubes and just 1/4″ OD tubing (no adapter is necessary). For maximum accuracy in the CSP-5000 series, KMD-7000 series, and BAC-7000 series controllers, the 1/4″ OD tubing from the pickup tubes to the controller should be 24″ long (on both the High and the Low sides).
NOTE: For other controllers, the length of the tubing should not be longer than necessary.
NOTE: CSC-2000 series controllers have ports for 3/8″ tubing (the same as the SSS-10xx pickup tubes).
Check that there are no sharp bends in the tubing at any connection. Bends and creases may leak as tubing ages.
- Connect the Port “H” to the “High” input on the VAV controller.
- Connect the Port “L” to the “Low” input on the VAV controller.
Mounting for Static Pressure
To mount the pickup tubes for static pressure:
-
Determine the duct’s flow direction and install the pickup tubes so that the FLOW arrow imprint is perpendicular to the direction of the air flow.
NOTE: The FLOW arrow imprint on the pickup tubes can point either up or down.
NOTE: It is recommended that an indication or marking be applied to the SSS-10xx probe to indicate the intended orientation. -
Cut a 7/8″ (22 mm) hole in the duct to accept the pickup tubes.
-
Attach the pickup tubes to the duct using two self tapping screws inserted through the 3/16″ (5 mm) mounting holes.
NOTE: If mounting SSS-10xx pickup tubes perpendicular to a relatively small diameter round duct, take care not to break the pickup tubes by overtightening the screws and over flexing the plastic mount.
Connections
Using appropriately sized polyethylene tubing, connect either the H or L port
on the pickup tubes to the High port on the controller.
NOTE: The other port of the pickup tubes is left unconnected and open to
air.
NOTE: Tubing should be free of kinks and restrictions.
Select Specifications
Material: Light gray (SSS-100x) or almond (SSS-101x) ABS/polycarbonate
(UL94-5V)
Connection: 1/4″ nipple (SSS-100x) for 3/8″ OD polyethylene tubing or
3/16″ nipple (SSS-101x) for 1/4″ OD tubing.
K Factors: Refer to the data sheet for additional information!
NOTE: The appropriate “K” factor for the pickup tubes depends upon the type of setup required by the VAV controller with which it will be used:
-
For VAV controllers that require KCFM for setup, refer to the “Cubic Feet Per Minute (CFM)” chart below and the device documentation for additional information.
For rectangular ducts, KCFM = KFPM x (W” x H”/144) (with duct cross-section measurements in inches). -
For VAV controllers that require KFPM for setup, refer to the “Feet Per Minute” chart below and the device documentation for additional information

Maintenance
The air pickup orifices must be kept free of dust accumulation or debris. The pickup tubes are designed for dependable, long-term reliability and performance.
