NOTES:
1. Motor drive range is 796 to 1128 rpm for low range motor/drive and 1150 to
1438 rpm for high range motor/drive. All other rpms require a field-supplied
drive,
2. Maximum continuous bhp is 2.40 for low range motor/drive and 3.10 for high
range motor/drive.
3. See below for General Fan Performance Notes.
GENERAL NOTES FOR FAN PERFORMANCE DATA TABLES
1. Static pressure losses (i.e., economizer, etc.) must be added to
external static pressure before entering Fan Performance table.
2. Interpolation is permissible. Do not extrapolate.
3. Fan performance is based on wet coils, clean filters, and casing
losses. Refer to the unit Product Data literature for Accessory/
FlOP Static Pressure information.
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 the
local Carrier representative for details.
6. Use the following formula to calculate input watts:
Input Watts = Bhp x (746/Motor Eft)
