NOTES:
1. 45J maximum primary airflow (cfm) is set by the maximum induced airflow,
which may vary as a function of downstream pressure. Maximum airflow
shown is based on the maximum induced airflow (fan airflow) or 1.00 in.
wg differential pressure signal from inlet airflow sensor, whichever is less.
2. Minimum recommended primary airflow (cfm) is based on 0.03 in. wg dif-
ferential pressure of the inlet airflow sensor, or 0 airflow. 0.03 in. wg is
equal to 15% to 20% of the nominal flow rating of the terminal. Less than
15% to 20% may result in greater than +5% control of box flow.
3. 45J maximum/minimum fan airflow is based on 0.10 in. wg / 0.60 in. wg
downstream static pressure, respectively.
