controls for proper operation each heating and cooling
seas
on. Service as necessary.
NOTE
: The installing technician should explain system

--- Shaded boxes represent airflow outside the required 300-450 cfm/ton.
NOTES:
1. Airflow based upon dry coil at 230V with no electric
heat and factory---approved filter.
2. Airflow is equivalent for front or bottom return configurati
ons.

--- Shaded boxes represent airflow outside the required 300-450 cfm/ton.
NOTES:
1.
Airflow based upon dry coil at 230V with no electric heat and factory---approved filter. For FMA4X airflow at 208V is approximately the same as 230V because
the multi ---tap ECM motor is a constant torque motor. The torque doesn’t
drop off at the speeds in which the motor operates.
2.
Airflow is equivalent for front or bottom return configurations.
