NOTES:

  1. Airflow values were measured with 23kW heater kit and clean factory air filter installed, and no cooling coil cabinet attached.
  2. If using 15kW or 17 kW of electric heat, add 50 cfm to these values. If using 10kW or 12kW, add 100 cfm to these values.
  3. Pressure drop of clean factory air filter is 0.08 inch W.C.
