PERFORMANCE DATA (cont)
GENERAL NOTES FOR FAN PERFORMANCE DATA TABLES
1. Values include losses for filters, unit casing, and wet coils. See this
page 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 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 Evaporator-Fan Motor Performance table on page 79
for additional information.
3. Use of a field-supplied motor may affect wire sizing. Contact your
Bryant representative for details.
4. Interpolation is permissible. Do not extrapolate. (Belt drive units
only.)
OUTDOOR SOUND POWER (Total Unit)
NOTE: Indoor sound power is available in Bryant’s Electronic Catalog program (ECAT) for specific operating parameters.
ACCESSORY/FIOP ECONOMIZER IV AND ECONOMI$ER2 STATIC PRESSURE* (in. wg) — 580F036-073
LEGEND *The static pressure must be added to external static pressure. The
sum and the evaporator entering-air cfm should be used in conjunction
with the Fan Performance tables to determine indoor blower rpm and
watts.
ACCESSORY/FIOP ECONOMISER IV AND ECONOMI$ER2 STATIC PRESSURE* (in. wg) — 580F090-151
LEGEND *The static pressure must be added to external static pressure. The
sum and the evaporator entering-air cfm should then be used in con-
junction with the Fan Performance tables to determine blower rpm and
watts.
