NOTES:
1. Values include losses for filters, unit casing, and wet coils.
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 nuisance tripping or premature failure.
Unit warranty will not be affected. See Evaporator-Fan Motor Performance
table on page 60 for additional information.
3. Use of a field-supplied motor may affect wire sizing. Contact your local repre-
sentative to verify.
4. Minimum allowable cfm is 300 cfm/ton.
