GENERAL FAN PERFORMANCE NOTES
1.Values include losses for filters, unit casing, and wet coils. See Fig. 38 and Table 9 for accessory/FIOP static pressure information.
2.Extensive motor and electrical testing on these units ensures that the full range of the motor can be utilized with confidence. Using the fan motors up to the ratings shown will not result in nuisance tripping or premature motor failure. Unit warranty will not be affected. See Tables 7 and 8 for additional information.
