Add these resistance values to the available static resistance in the respective Blower Performance Tables.Economizer2 32. Deduct these resistance values from the available external static pressure shown in the respective Blower Perfor-mance Table.3. The pressure drop through the economizer is greater for 100% outdoor air than for 100% return air. If the resistance ofthe return air duct system is less than 62.1 Pa, the unit will deliver less M3S during full economizer operation.Electric Heat kW218 24 36 540.89 14.9 5.0 14.9 17.4 19.9 24.80.99 17.4 5.0 17.4 19.9 22.4 27.31.08 19.9 5.0 19.9 22.4 24.8 32.31.18 22.4 5.0 22.4 24.8 27.3 34.81.27 27.3 7.5 24.8 29.8 32.3 39.71.36 29.8 7.5 27.3 32.3 34.8 44.71.46 34.8 7.5 32.3 37.3 39.7 49.71.55 39.7 7.5 34.8 42.2 44.7 54.61.65 44.7 9.9 39.7 47.2 49.7 59.61.74 49.7 9.9 44.7 52.2 49.7 64.61.83 57.1 9.9 49.7 57.1 59.6 69.51.93 62.1 9.9 54.6 62.1 64.6 77.01.02 69.5 12.4 59.6 69.5 72.0 84.42.12 74.5 12.4 64.6 74.5 77.0 91.92.21 82.0 12.4 72.0 82.0 84.4 99.32.30 89.4 12.4 77.0 86.9 91.9 106.82.40 96.9 14.9 84.4 94.4 99.3 114.22.49 104.3 14.9 91.9 101.8 106.8 121.72.59 111.8 14.9 99.3 109.3 114.2 131.62.68 119.2 14.9 106.8 116.7 121.7 139.12.77 129.1 17.4 114.2 124.2 131.6 146.52.87 139.1 17.4 121.7 131.6 139.1 154.02.96 149.0 17.4 131.6 139.1 146.5 161.4Table 30: Additional Static Resistance DC090 Cabinet (Metric)M 3S Cooling Only 1 Economizer2 30.9 -0.99 17.400.99 2.50 22.401.09 2.50 27.401.18 4.98 32.401.27 7.50 39.901.37 10.00 44.831.46 12.50 49.811.56 14.90 54.801.65 17.40 59.801.75 19.90 67.201.84 22.40 72.201.93 22.40 77.202.03 24.90 82.201.
