NOTES - The e󰀨ect 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. Lennox Harmony III™ Zoning System Applications - Minimum blower speed is 478 cfm.
