*Air delivery values are without air filter and are for dry coil (See Table 9 --- 48EZ---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. Note: Deduct 10% for 208 volt operation.
