All motors have a nominal speed of 1800 RPM, a 1.15 service factor and a solid base. They can operate to the limit of their service factor becausethey are located in the moving air, upstream of any heating device.2. Do NOT close this pulley below 1 turn open.TABLE 30: STATIC RESISTANCES 1DESCRIPTIONRESISTANCE, IWGCFM15 TON 20 TON 25 TON4500 5600 7500 6000 8000 9400 7500 10000 12500WET INDOOR COIL 0.1 0.1 0.1 0.1 0.1 0.1 0.11 0.11 0.11ELECTRIC HEAT OPTIONS18 KW 0.3 0.35 0.39 0.35 0.4 0.45 0.40 0.45 0.5536 KW 0.32 0.40 0.44 0.40 0.48 0.50 0.45 0.5 0.654 KW 0.38 0.45 0.49 0.45 0.52 0.57 0.5 0.6 0.772 KW 0.38 0.45 0.49 0.45 0.52 0.57 0.5 0.6 0.7ECONOMIZER OPTION 0.1 0.1 0.1 0.1 0.1 0.1 0.06 0.11 0.18VERTICAL DUCT CONNECTIONS 2 0.1 0.2 0.3 0.2 0.3 0.5 0.36 0.32 0.461. Deduct these resistance values from the available external static pressures shown in the respective Blower Performance Table (See Note 2 forexception.)2. Since the resistance to air flow will be more for vertical duct connections than for side duct connections, deduct these pressures from the ESP valueson the respective unit’s blower performance table.TABLE 31: POWER EXHAUST PERFORMANCEMOTORSPEED1STATIC RESISTANCE OF RETURN DUCTWORK, IWG0.2 0.3 0.4 0.5 0.6CFM kW CFM kW CFM kW CFM kW CFM kWHIGH2 5250 0.83 4500 0.85 4200 0.88 3750 0.93 3000 0.99MEDIUM 4900 0.77 3900 0.79 3500 0.82 2900 0.85 - -LOW 4400 0.72 3700 0.74 3000 0.78 - - - -1.
