7.5 HP Oversized Motor & Sheaves<br />
For Standard Evaporator Fan Speed (RPM), reference Table PD-31.<br />
For Standard Motor & High Static Drive Accessory Fan Speed (RPM), reference Table PD-32.<br />
For Oversized Evaporator Fan Speed (RPM), reference Table PD-33.<br />
Fan motor heat (MBH) = 3.15 x Fan BHP<br />
Data includes pressure drop due to wet coils and filters.<br />
No accessories or options are included in pressure drop data.<br />
Refer to Table PD-35 to determine add’l static pressure drop due to other options/accessories.<br />
Notes:<br />
1. Field Supplied Fan Sheave BK190 Required. Field Supplied Belt may be necessary.<br />
2. 7.5 HP Standard Motor <strong>with</strong> Field Supplied Motor Sheave IVP50 Required. Field Supplied Belt<br />
may be necessary.<br />
3. For 380V/60 Hz units, the oversized motor is used as the standard motor. Refer to “Motor &<br />
Sheave/Fan Speed” tables to determine operating range.<br />
Factory supplied motors, in commercial equipment, are<br />
definite purpose motors, specifically designed and tested to<br />
operate reliably and continuously at all cataloged conditions.<br />
Using the full horsepower range of our fan motors as shown<br />
in our tabular data will not result in nuisance tripping or<br />
premature motor failure. Our product’s warranty will not be<br />
affected.<br />
*Indicates both downflow and horizontal units.<br />
