NOTES − The effect of static pressure is included in air volumes shown.
First stage HEAT is approximately 91% of the same second stage
HEAT speed position.
First stage COOL (two−stage air conditioning units only) is approximately 70% of the same second stage COOL speed position.
Continuous Fan Only speed is approximately 38% of the same second stage COOL speed position − minimum 500 cfm (235 L/s).
