*Based on 5 psig steam, 60 F entering-air temperature. All steam coils
are non-freeze type.
†Based on 200 F entering water, 20 F water temperature drop, 60 F
entering-air temperature.
NOTES:
1. Maximum operating limits for heating coils: 175 psig at 400 F.
2. Leaving db = ent db (F) +
3. See Heating Correction Factors table.

Bold indicates field-supplied drive is required.
Plain type indicates standard motor and standard drive.
Underline indicates a different motor and drive combination other than
the standard motor and standard drive is required. Refer to fan motor
and drive tables, pages 35 and 36, to complete the selection.
NOTES:
1. Maximum allowable fan speed is 1200 rpm for all sizes.
2. Fan performance is based on deductions for wet coil, clean 2-in. fil-
ters, and unit casing. See table at right for factory-supplied filter
pressure drop.
