*Air delivery values are without air filter and are for dry coil (See 677C --- ---A Wet Coil Pressure Drop table).

1 Factory ---shipped gas heating speed

2 Factory ---shipped heat pump speed NA --- Not allowed for heating speed

Note: Deduct field---supplied air filter pressure drop and wet coil pressure drop to obtain external static pressure available for ducting. Shaded areas indicate speed/static combinations that are not permitted for dehumidification speed.
