Table 16 — Fan Performance — 579F180 (High Heat Units)
LEGEND
NOTES:
1. Standard low-medium static drive range is 891 to 1179 rpm. Alternate high-
static drive range is 1227 to 1550. Other rpms require a field-supplied drive.
2. Maximum continuous bhp is 4.25 and the 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.
3. Static pressure losses (i.e., EconoMi$erIV) must be added to external static
pressure before entering Fan Performance table.
4. Interpolation is permissible. Do not extrapolate.
5. Fan performance is based on wet coils, clean filters, and casing losses. See
Table 20 for accessory/FIOP static pressure information.
6. Extensive motor and drive testing on these units ensures that the full horse-
power and watts range of the motor can be utilized with confidence. Using
the fan motors up to the watts or bhp rating shown will not result in nuisance
tripping or premature motor failure. Unit warranty will not be affected.
7. Use of a field-supplied motor may affect wiring size. Contact the local Bryant
representative for details.
Table 17 — Fan Performance — 579F216 and 240 (High Heat Units)
LEGEND
NOTES:
1. Standard low-medium static drive range for size 216 is 910 to 1095 rpm.
Standard low-medium static drive range for size 240 is 1002 to 1225 rpm.
Alternate high-static drive range for size 216 is 1069 to 1287. Alternate high-
static drive range for size 240 is 1193 to 1458 rpm. Other rpms require a
field-supplied drive.
2. Maximum continuous bhp for size 216 is 5.90. Maximum continuous bhp for
size 240 is 8.7 (208/230 v) or 9.5 (460 v). The maximum continuous watts for
size 216 is 5180. The maximum continuous watts for size 240 is 7915
(208/230 v) or 8640 (460 v). Do not adjust motor rpm such that motor maxi-
mum bhp and/or watts is exceeded at the maximum operating cfm.
3. Static pressure losses (i.e., EconoMi$erIV) must be added to external static
pressure before entering Fan Performance table.
4. Interpolation is permissible. Do not extrapolate.
