LEGEND
NOTES:
1. Boldface indicates field-supplied drive required.
2.
indicates field-supplied motor and drive required.
3. Factory-shipped motor drive range is 862 to 1132 rpm. Other rpms
may require a field-supplied drive.
4. Maximum continuous bhp is 4.25 maximum continuous watts are
3775. Do not adjust motor rpm such that motor maximum bhp and/
or watts is exceeded at the maximum operating cfm.
5. Static pressure losses (i.e., EconoMi$erIV) must be added to
external static pressure before entering Fan Performance table.
6. Interpolation is permissible. Do not extrapolate.
7. Fan performance is based on wet coils, clean filters, and casing
losses. See Table 12 for accessory/FIOP static pressure information.
8. Extensive motor and drive testing on these units ensures that the
full horsepower and watts range of the motor can be utilized with
confidence. Using fan motors up to the watts or bhp rating shown
will not result in nuisance tripping or premature motor failure. Unit
warranty will not be affected.
