These ratings include the compressor and the condenser fan motors but not the supply air blower motor. The total condenser fanmotor power input is 0.36kW. Refer to the SUPPLY AIR BLOWER PERFORMANCE Table for the kW of the supply air blower motor.Gross Sensible Capacity2 (MBh)2. These capacities are gross ratings. For net capacity, determine the kW of the supply air blower motor from the SUPPLY AIR BLOWERPERFORMANCE Table, multiply this value by 3.425 MBH/kW to determine the motor heat, and deduct this heat from the gross capacityof the unit.Nominal RatingGrossCapacity(MBh)PowerInput(kW)Gross Sensible Capacity (MBh)CFM WB(°F)Return Air Dry Bulb (°F) Return Air Dry Bulb (°F)86 83 80 77 74 71 68 90 85 80 75 70 65 6885°F 95°F275072 83.1 5.24 54.6 46.4 38.2 30.0 21.8 - - 80.2 5.92 53.1 44.9 36.7 28.5 20.3 - -67 79.5 5.15 67.8 59.6 51.4 43.2 35.0 26.8 18.6 75.3 5.80 66.6 58.4 50.2 42.0 33.8 25.6 17.462 72.7 5.08 72.7 72.7 64.8 56.6 48.4 40.2 32.0 68.3 5.74 68.3 68.3 62.5 54.3 46.1 37.9 29.757 66.7 5.04 66.7 66.7 64.6 56.4 48.2 40.0 31.8 65.8 5.77 65.8 65.8 64.5 56.3 48.1 39.9 31.7247572 82.4 5.25 52.1 44.8 37.5 30.2 22.9 - - 79.9 5.89 50.5 43.2 35.9 28.6 21.3 - -67 78.8 5.16 65.0 57.7 50.4 43.1 35.8 28.5 21.2 75.0 5.78 63.8 56.5 49.1 41.8 34.5 27.2 19.962 72.1 5.10 72.1 70.7 63.5 56.2 48.9 41.6 34.3 68.0 5.72 68.0 67.3 61.2 53.9 46.6 39.3 32.057 66.1 5.05 66.1 66.1 63.4 56.1 48.8 41.5 34.1 65.5 5.74 65.5 65.5 63.1 55.8 48.5 41.2 33.9220072 81.7 5.26 49.6 43.2 36.8 30.3 23.9 - - 79.6 5.87 48.0 41.6 35.2 28.7 22.3 - -67 78.1 5.18 62.3 55.8 49.4 43.0 36.6 30.2 23.8 74.7 5.75 60.9 54.5 48.1 41.7 35.3 28.9 22.462 71.4 5.11 71.4 68.7 62.3 55.9 49.5 43.1 36.6 67.7 5.69 67.7 66.3 59.9 53.5 47.1 40.7 34.357 65.5 5.06 65.5 65.5 62.1 55.7 49.3 42.9 36.5 65.2 5.72 65.2 65.2 61.8 55.4 49.0 42.6 36.2192572 79.3 5.24 45.6 40.0 34.5 28.9 23.4 - - 77.1 5.86 43.9 38.4 32.8 27.2 21.7 - -67 75.8 5.15 57.5 51.9 46.4 40.8 35.3 29.7 24.1 72.3 5.74 56.0 50.4 44.9 39.3 33.8 28.2 22.662 69.4 5.08 67.7 64.0 58.5 52.9 47.3 41.8 36.2 65.6 5.68 64.5 61.5 55.9 50.3 44.8 39.2 33.757 63.6 5.04 63.6 62.3 58.3 52.7 47.2 41.6 36.1 63.2 5.71 63.2 61.7 57.7 52.1 46.5 41.0 35.4165072 77 5.21 41.6 36.9 32.2 27.5 22.8 - - 74.5 5.85 39.8 35.1 30.4 25.7 21.0 - -67 73.6 5.12 52.7 48.0 43.3 38.6 33.9 29.2 24.5 69.9 5.73 51.0 46.3 41.6 36.9 32.2 27.5 22.862 67.3 5.06 64.0 59.3 54.6 49.9 45.2 40.5 35.8 63.4 5.67 61.3 56.6 51.9 47.2 42.5 37.7 33.057 61.7 5.01 61.7 59.2 54.5 49.8 45.0 40.3 35.6 61.1 5.70 61.1 58.2 53.5 48.8 44.1 39.4 34.7105°F 115°F275072 76.3 6.66 51.5 43.3 35.1 26.9 18.7 - - 72.4 7.40 50.0 41.8 33.6 25.4 17.2 - -67 70.2 6.55 64.2 56.0 47.8 39.6 31.5 23.3 15.1 65.0 7.31 61.9 53.7 45.5 37.3 29.1 20.9 12.762 62.2 6.48 62.2 62.2 58.8 50.6 42.4 34.2 26.0 56.1 7.22 56.1 56.1 55.2 47.0 38.8 30.6 22.457 61.2 6.50 61.2 61.2 60.1 51.9 43.7 35.5 27.3 56.7 7.24 56.7 56.7 55.7 47.5 39.3 31.1 22.9247572 76.1 6.63 49.0 41.7 34.3 27.0 19.7 - - 72.3 7.36 47.4 40.1 32.8 25.5 18.2 - -67 70.0 6.52 61.4 54.1 46.8 39.5 32.2 24.9 17.6 65.0 7.26 59.1 51.7 44.4 37.1 29.8 22.5 15.262 62.0 6.45 62.0 61.7 57.5 50.2 42.9 35.6 28.3 56.1 7.18 56.1 56.1 53.9 46.6 39.2 31.9 24.657 61.0 6.47 61.0 61.0 58.8 51.5 44.2 36.9 29.5 56.6 7.19 56.6 56.6 54.4 47.1 39.8 32.5 25.2220072 75.9 6.59 46.4 40.0 33.6 27.2 20.7 - - 72.2 7.31 44.8 38.4 32.0 25.6 19.2 - -67 69.8 6.48 58.6 52.2 45.7 39.3 32.9 26.5 20.1 64.9 7.22 56.2 49.8 43.4 37.0 30.5 24.1 17.762 61.9 6.41 61.9 61.2 56.2 49.8 43.4 37.0 30.6 56.0 7.13 56.0 56.0 52.6 46.2 39.7 33.3 26.957 60.9 6.43 60.9 60.9 57.5 51.0 44.6 38.2 31.8 56.5 7.15 56.5 56.5 53.1 46.7 40.3 33.9 27.4192572 73.1 6.58 42.3 36.7 31.1 25.6 20.0 - - 69.1 7.30 40.6 35.0 29.5 23.9 18.4 - -67 67.2 6.47 53.5 48.0 42.4 36.9 31.3 25.7 20.2 62.1 7.20 51.1 45.5 40.0 34.4 28.8 23.3 17.762 59.6 6.40 59.1 57.0 52.2 46.6 41.0 35.5 29.9 53.6 7.12 53.6 52.5 48.4 42.9 37.3 31.7 26.257 58.6 6.42 58.6 57.3 53.3 47.7 42.2 36.6 31.0 54.1 7.13 54.1 53.0 48.9 43.3 37.8 32.2 26.7165072 70.3 6.57 38.1 33.4 28.7 24.0 19.3 - - 66.1 7.28 36.4 31.7 26.9 22.2 17.5 - -67 64.6 6.46 48.5 43.8 39.1 34.4 29.7 25.0 20.3 59.4 7.19 45.9 41.2 36.5 31.8 27.1 22.4 17.762 57.3 6.39 56.3 52.8 48.1 43.4 38.7 34.0 29.2 51.2 7.11 51.2 49.0 44.3 39.6 34.9 30.2 25.557 56.4 6.41 56.4 53.8 49.1 44.4 39.7 35.0 30.3 51.7 7.12 51.7 49.4 44.7 40.0 35.3 30.6 25.9
