NOTES − The effect of static pressure, filter and electric heater resistance is included in the air volumes listed.
Low speed cooling air volume is 70% of COOL speed setting. Production units September 2005 and later; continuous blower speed for is approximately 38% of
COOL speed setting. Earlier production units continuous blower speed is approximately 50% of COOL speed setting.
Harmony Zone Control applications − Low speed cooling is approximately 250 cfm (118 L/s).
Lennox Harmony IIIt Zone Control applications − Low speed cooling is 300 cfm (145 L/s)
