*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.

NOTES:
1. Maximum allowable fan speed is 1200 rpm.
2. Fan performance is based on deductions for wet coil, clean 2-in. filters, and unit
casing. See page 13 for factory-supplied filter pressure drop.
3. Refer to fan motor and drives tables, page 21 to complete the selection.
