BLOWER DATA
G60UHV−60C−090 BLOWER PERFORMANCE
0 through 0.80 in. w.g. (0 Through 200 Pa) External Static Pressure Range
Single Side Return Air − Air volumes in bold require field fabricated transition to accommodate 20 x 25 x 1 in. (508 x 635 x 25 mm) clean-
able air filter in order to maintain proper air velocity across the filter.

NOTES − The effect of static pressure and filter resistance is included in air volumes shown.
1st stage HEAT is approximately 91% of the same 2nd stage HEAT speed position.
1st stage COOL (two speed air conditioning units only) is approximately 70% (60% for units built prior to 09−2002) of the same 2nd stage COOL speed position.
Continuous Fan Only speed is approximately 38% of the same 2nd stage COOL speed position.
Lennox Harmony II zone control applications − Minimum blower heating speed is approximately 75% of the 1st stage HEAT speed position.
Lennox Harmony II zone control applications − Minimum blower cooling speed is approximately 42% of the 2nd stage COOL speed position.
