NOTES:
1. Values include losses for filters, unit casing, and wet coils. See
page 47 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
your fan motors up to the wattage ratings shown will not result in nui-
sance tripping or premature motor failure. Unit warranty will not be
affected. For additional information on motor performance, refer to
Evaporator-Fan Motor Performance table on page 62.
3. Use of a field-supplied motor may affect wire sizing. Contact your lo-
cal representative for details.
4. Minimum allowable cfm is 300 cfm/ton.
