FAN PERFORMANCE — HORIZONTAL DISCHARGE UNITS (cont)
LEGEND
NOTES :
1. Boldface indicates field-supplied drive required. (See Note 3.)
2.
indicates field-supplied motor and drive required.
3. Motor drive range is 840 to 1085 rpm for standard motors; 860 to 1080 rpm
for high-static motors. All other rpms require a field-supplied drive.
4. Values include losses for filters, unit casing, and wet coils. See page 49 for
accessory/FIOP static pressure information.
5. Maximum continuous bhp is 2.9 for standard motors, 4.2 for high-static
motors. 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 ratings shown will not result in nuisance tripping or premature motor
failure. Unit warranty will not be affected. See Evaporator-Fan Motor Data
tables on pages 47 and 48 for additional information.
6. Use of a field-supplied motor may affect wire sizing. Contact your Carrier rep-
resentative to verify.
7. Interpolation is permissible. Do not extrapolate.
