PERFORMANCE DATA — 542J (cont)
FAN PERFORMANCE — VERTICAL DISCHARGE UNITS (cont)
LEGEND
*Standard drive range is 817 to 1038 rpm. Alternate drive range is 1082
to 1303. Other rpms may require a field-supplied drive.
NOTES:
1. Maximum continuous bhp is 5.90 and maximum continuous watts
are 5180. Do not adjust motor rpm such that motor maximum bhp
and/or watts is exceeded at the maximum operating cfm.
2. Fan performance is identical for horizontal discharge applications
using horizontal adapter curb (CRRFCURB013A00).
3. See this page for General Fan Performance notes.
GENERAL NOTES FOR FAN PERFORMANCE TABLES
1. 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 motor failure. Unit warranty will not
be affected. For additional information on motor performance,
refer to Indoor-Fan Motor Performance table on page 150.
2. Values include losses for filters, unit casing, and wet coils. See
page 151 for accessory/FIOP static pressure 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.
