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 (65% COOL speed for production prior to August 2002). 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 380 cfm (178 L/s).
Lennox Harmony IIIt Zone Control applications − minimum blower speed is 442 cfm (210 L/s).
