GENERAL NOTES FOR FAN PERFORMANCE DATA TABLES

1.Static pressure losses from accessories and options (economizer, etc.) must be added to external static pressure before entering Fan Performance table. Refer to Accessory/FIOP Static Pressure information.

2.Interpolation is permissible. Do not extrapolate.

3.Fan performance tables are based on wet coils, clean filters, and casing losses. Gas heat losses are included for 48 series units.

4.Extensive motor and drive testing on these units ensures that the full horsepower range of the motor can be utilized with confidence. Using the fan motors up to the bhp rating shown will not result in nuisance tripping or premature motor failure. Unit warranty will not be affected.

5.Use of a field-supplied motor may affect wire size. Recalculate the unit power supply MCA and MOCP if required. Contact your Carrier representative for details.

6.Use the following formula to calculate input watts: Input Watts = Bhp x (746/Motor Eff)
