KMC Controls SSS-1000 Series Installation Manual

Mounting
1. Determine the duct's flow direction and install
the sensor based on the sensor's flow arrow
imprint.
NOTE: The sensor must be mounted with the
arrow pointing in the direction of the air
flow.
2. Cut a 7/8" hole in the duct to accept the sensor's
probes.
3. Attach the sensor to the duct using two self-
tapping screws inserted through the sensor's
3/16" mounting holes.

Connections
Connect the sensor to the controller using appropri-
ately sized polyethylene tubing:
• For using SSS-100x sensors with CSC-3000 series,
CSP-4000/5000 series, KMD-7000 series, and
BAC-7000/8000/9000 series controllers, use a barb
union adapter and appropriately sized tubing to
the sensor and controller. For maximum accuracy
in the CSP-5000 series, KMD-7000 series, and
BAC-7000 series controllers, the 3/8" OD tubing
between the sensor 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 sensor 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
SSS-1000 Series

1/4" OD tubing from the sensor 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-100x
sensors).
Check that there are no sharp bends in the tubing
at any connection. Bends and creases may leak as
tubing ages.
1. Connect the Port "H" to the "High" input on the
VAV controller.
2. Connect the Port "L" to the "Low" input on the VAV
controller.
