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. 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. See
Evaporator--Fan Motor Specifications for additional
information.
3. Use of a field-supplied motor may affect wire size. Contact
your Carrier representative for details.
4. Interpolation is permissible. Do not extrapolate.
