Step 3 — Install Sensors and Make Field Wiring
Connections — Electric Analog or DDC (Direct
Digital Controls) —
Refer to specific unit dimensional
submittals and control application diagrams for control specifi-
cations. All field wiring must comply with National Electrical
Code (NEC) and local requirements. Refer to the wiring diagram
on the unit for specific wiring connections.
A field-supplied transformer is required if the unit was not
equipped with a factory-installed transformer. See Fig. 3.
NOTE: Refer to wiring diagram attached to each unit for
specific information on that particular unit.
Unit airflow should not be set outside of the range noted in
Fig. 4A-4C and the performance data section of this document.
Table 3 — 35L Non-Mixing Dual Duct Basic Pressure Data
*CCN (Carrier Comfort Network®) controls permit a lower minimum
flow.
NOTES:
1.
∆
P
s
is the difference in static pressure across the assembly,
with the damper fully open.
2. To obtain Total Pressure, add the Velocity Pressure for a
given CFM to the Static Pressure drop (
∆
P
s
) of the desired
configuration.
