3. Values include losses for filters, unit casing, and wet coils. See
Table 7 for accessory/FIOP static pressure information.
4. Maximum continuous bhp is 1.30 for single-phase units and 2.40
for 3-phase units and the maximum continuous watts are 2120.
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. See Table 6 — Motor Data for additional information.
5. Use of a field-supplied motor may affect wire sizing. Contact your
Carrier representative for details.
6. Interpolation is permissible. Do not extrapolate.
