The pressure drop through the economizer is greater for 100% outdoor air than for 100% return air. If the resistance of thereturn air duct is less than 0.25 IWG, the unit will deliver less CFM during full economizer operation.Table 10: Electric Heat Minimum Supply AirSize(Tons) Model VoltageMinimum Supply Air (CFM)Heater kW5.0 7.5 10.0 15.0 20.0 25.0024(2.0) DEX 208/230-1-60 630 630 800 - - -030(2.5) DEX 208/230-1-60 630 630 800 800 - -036(3.0) DEX208/230-1-60 1070 1070 1070 1070 - -208/230-3-60 1070 1070 1070 1070 - -460-3-60 1070 1070 1070 1070 - -042(3.5) DEX208/230-1-60 1225 1225 1225 1225 - -208/230-3-60 1225 1225 1225 1225 - -460-3-60 1225 1225 1225 1225 - -048(4.0) DEX208/230-1-60 - - 1200 1430 1430 1430208/230-3-60 - - 1200 1430 1430 1430460-3-60 - - 1200 1430 1430 1430060(5.0) DEY208/230-1-60 - - 1615 1615 1955 1955208/230-3-60 - - 1615 1615 1955 1955460-3-60 - - 1615 1615 1955 1955Table 9: Additional Static Resistance (Continued)Size(Tons) Model CFM Wet Indoor Coil Economizer 1 Filter/Frame Kit Electric HeatTable 11: Indoor Blower SpecificationsSize(Tons) Model MotorHP RPM Eff.
