Airflow Data

Airflow (CFM) vs. External Static Pressure (IN. W.C.)

A table provides airflow data for the E7E*-0**H1 model across various motor switch settings (0=OFF, 1=ON) and external static pressures from 0.1 to 0.6 IN. W.C. The data shows CFM values for each combination.

Maximum Heating Airflow Setting

This table specifies the maximum allowable heat settings for different models (E7EM, E7ED, E7EU) and applications (MH - Manufactured Housing, RES - Residential) based on airflow settings (e.g., 0101, 0001, 0011).

Notes:

• Motor switch settings for heating speeds use HEAT switches 1, 2, 3, and 4. For cooling speeds use COOL switches 5, 6, 7, and 8.
• Data is shown with filter.
• MH and Res represent Manufactured Housing and Residential (modular home) applications, respectively.
• To comply with government mandated efficiency standards, speed settings with higher CFM values than listed in this table are not allowed in HEAT mode.
