*|f other than 75 C copper wire is used, determine size from unit ampacity and the National Electrical Code. Voltage drop of wire must be less than 2%
of unit rated voltage.
fRated in accordance with U.S. Government D.O.E. test procedures and/or ARI Standard 210.
tRated in accordance with ARI Standard 270.
**The capacity ratings of single-phase units are in accordance with U.S. Government D.O.E. test procedures and/or A.G.A. certification requirements. For
3-phase units, the efficiency rating is a product thermal efficiency rating determined under continuous operating conditions, independent of any
installed system.
tf Required filter areas shown are based on the larger of the ARI-rated cooling airflow or the heating airflow at a velocity of 300 ft/min for disposable type
or 450 ft/min for high-capacity type. Air filter pressure drop must not exceed 0.08 in.-water.
