For sideflow duct applications; 1.Remove and discard the side supply and return air duct covers. 2.Connect ductwork to duct flanges on the rear of the unit. For downflow duct applications; 1. Remove the side supply and return air duct covers to gain access to the bottom supply and return air duct covers. 2. Remove and discard the bottom duct covers. 3. Replace the side duct covers. 727 (28-5/8") (180) DETAIL “X” ACCESSORY SIDE SUPPLY AND RETURN AIR DUCT OPENINGS 397 1558“ 610 (24") (180) DETAIL “Y” UNIT WITH ECONOMIZER AND FIXED OUTDOOR AIR HOODS FIG. 7 (Cont'd.) - DIMENSIONS AND CLEARANCES Unitary Products Group 035-18895-000-A-0902 TABLE 4 - SUPPLY AIR BLOWER PERFORMANCE DOWNFLOW DUCT APPLICATIONS (m3 /s) - B*CH180 UNIT BLOWER SPEED, RPM MOTOR PULLEY (TURNS OPEN)* AIRFLOW 1.77 m3/s 2.07 m3/s 2.36 m3/s 2.66 m3/s 2.95 m3/s ESP (Pa) Output (kW) Input (kW) ESP (Pa) Output (kW) Input (kW) ESP (Pa) Output (kW) Input (kW) ESP (Pa) Output (kW) Input (kW) ESP (Pa) Output (kW) Input (kW) 845 6.0 273 1.56 1.8 223 1.79 2.2 198 2.09 2.5 174 2.38 2.9 149 2.68 3.2 885 5.0 322 1.64 1.9 273 1.94 2.3 223 2.24 2.7 198 2.53 3.1 174 2.83 3.4 925 4.0 372 1.71 2.1 322 2.01 2.5 248 2.38 2.9 223 2.68 3.3 --- 960 3.0 422 1.79 2.2 347 2.16 2.6 298 2.46 3.0 248 2.83 3.4 --- 1000 2.0 446 1.86 2.3 397 2.24 2.7 347 2.61 3.2 ------ 1040 1.0 496 1.94 2.4 446 2.38 2.9 372 2.76 3.3 ------ DOWNFLOW DUCT CONNECTIONS (CFM) - B*CH180 UNIT BLOWER SPEED, (RPM) MOTOR PULLEY (TURNS OPEN)* AIRFLOW 3750 CFM 4380 CFM 5000 CFM 5630 CFM 6250 CFM ESP (iwg) Output (bhp) Input (kW) ESP (iwg) Output (bhp) Input (kW) ESP (iwg) Output (bhp) Input (kW) ESP (iwg) Output (bhp) Input (kW) ESP (iwg) Output (bhp) Input (kW) 845 6.0 1.1 2.1 1.8 0.9 2.4 2.2 0.8 2.8 2.5 0.7 3.2 2.9 0.6 3.6 3.2 885 5.0 1.3 2.2 1.9 1.1 2.6 2.3 0.9 3.0 2.7 0.8 3.4 3.1 0.7 3.8 3.4 925 4.0 1.5 2.3 2.1 1.3 2.7 2.5 1.0 3.2 2.9 0.9 3.6 3.3 --- 960 3.0 1.7 2.4 2.2 1.4 2.9 2.6 1.2 3.3 3.0 1.0 3.8 3.4 --- 1000 2.0 1.8 2.5 2.3 1.6 3.0 2.7 1.4 3.5 3.2 ------ 1040 1.0 2.0 2.6 2.4 1.8 3.2 2.9 1.5 3.7 3.3 ------ NOTES: 1. Blower performance includes fixed outdoor air, standard unit filters, a dry indoor coil and no electric heat. 2. Refer to Table 5 for additional static resistances. ESP = External Static Pressure available for the supply and return air duct system. All internal unit resistances have been deducted from the total static pressure of the blower. * Do NOT close the pulley below 1 turn open.
