Note:
EXH/V 0.5 to 6 ton high efficiency units only: Units
are shipped from the factory on profile setting B.
To adjust the cfm, disconnect the power to the unit. Set the
DIP switch located in the control box to the desired profile
setting. Connect the power to the unit.
Profile A = 110% of rated airflow
Profile B = 100% of rated airflow
Profile C = 90% of rated airflow
Profile D = 80% of rated airflow
Installation at higher altitudes may require an adjustment
to the fan speed setting to achieve proper airflow. Use
profile C or D to get lower airflow. If a lower CFM is needed,
then set DIP switch 4 to ON.
