Brake Horsepower
High Range Motor/Drive Required
NOTES:
1. Motor drive range is 690 to 893 for low range motor/drive and 852 to 1055 rpm for
high range motor/drive. All other rpms require a field‐supplied drive.
2. Maximum continuous bhp is 3.70 for low range motor/drive and 5.25 for high range
motor/drive.
3. See General Fan Performance Notes.
GENERAL NOTES FOR FAN PERFORMANCE DATA TABLES
1. Static pressure losses from accessories and options
(Humidi-MiZer
system, 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)
