Note:
The Temperature Rise Tables can also be used to determine the air handler airflow
delivery. When using these tables for this purpose, set the room thermostat to maximum heat and
allow the system to reach steady state conditions. Set two thermometers, one in the return air inlet
and the other one in the supply air outlet.
