PERFORMANCE DATA — 542J (cont)
FAN PERFORMANCE — VERTICAL DISCHARGE UNITS
LEGEND
*Standard drive range is 891 to 1179 rpm. Alternate drive range is 1227 to 1559.
Other rpms may require a field-supplied drive.
NOTES:
1. Maximum continuous bhp is 4.25 and 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.
2. Fan performance is identical for horizontal discharge applications using hor-
izontal adapter curb (CRRFCURB013A00).
3. See page 149 for General Fan Performance notes.
LEGEND
*Factory-shipped motor drive range is 1159 to 1429 rpm. Other rpms may require
a field-supplied drive.
NOTES:
1. Maximum continuous bhp is 3.45 and maximum continuous watts are 3065.
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 hor-
izontal adapter curb (CRRFCURB013A00).
3. See page 149 for General Fan Performance notes.
