Esp — External Static Pressure (in. wg)
NOTES:
1. Values include losses for filters, unit casing, and wet coils.
2. Extensive motor and electrical testing on these units ensures that
the full range of the motor can be utilized with confidence. Using
your fan motors up to the wattage ratings shown will not result in
nuisance tripping or premature motor failure. Unit warranty will not
be affected. For additional information on motor performance, re-
fer to Table 4.
3. To convert watts to bhp:
watts input x motor efficiency
bhp =
746
Motor efficiency = .67

NOTES:
1. Boldface indicates a field-supplied drive is required. (See
Note 6.)
2. indicates field-supplied motor and drive are required.
3. Maximum usable watts input is 1921. Extensive motor and elec-
trical testing on these units ensures that the full range of the motor
can be utilized with confidence. Using your fan motors up to the
wattage ratings shown will not result in nuisance tripping or pre-
mature motor failure. Unit warranty will not be affected. For ad-
ditional information on motor performance, refer to Table 4.
4. Values include losses for filters, unit casing, and wet coils.
5. Use of a field-supplied motor may affect wire sizing. Contact
Carrier representative to verify.
6. Alternate motor drive range: 900 to 1300. All other rpms require
field-supplied drive.
7. To convert watts to bhp:
watts input x motor efficiency
bhp =
746
Motor efficiency = .74
