 - Airflow outside 450 cfm/ton.

NOTES:

1. Airflow based upon dry coil at 230v with factory

approved filter and electric heater (2 element heater sizes 1800 through 3600, 3 element heater sizes

4200 through 6000). For FEM4X, FEM4P, and REM4X models, airflow at 208 volts is approximately the same as 230 volts because the ECM motor is a

constant torque motor. The torque doesn’t drop off at the speeds the motor operates.

2. To avoid potential for condensate blowing out of drain pan prior to making drain trap:

Return static pressure must be less than 0.40 in. wc.

Horizontal applications of 4200 

 6000 sizes must have supply static greater than 0.20 in. wc.

3. Airflow above 400 cfm/ton on 4800 

 6000 size could result in condensate blowing off coil or splashing out of drain pan.
