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).

0.0" to 0.8" w.g. (0 through 200 Pa) External Static Pressure Range
Factory Settings: Heating Speed − 2; Cooling Speed − 4; Speed Adjust − NORM.
Return Air Options: Single side return air − Bold volumes require field−fabricated transition to accommodate
20 x 25 x 1 in. (508 x 635 x 25 mm) cleanable air filter in order to maintain proper air velocity across the filter.
