INDOOR UNIT ACCESSORY COILS — HYDRONIC
HEATING CAPACITIES
LEGEND
*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.
3. See Heating Correction Factors table.
INDOOR UNIT ACCESSORY COILS — HEATING
CORRECTION FACTORS
NOTE: Multiply capacity given in the Hydronic Heating Capacities table
by the correction factor for conditions at which unit is actually operating.
Correct leaving-air temperature using formula in Note 2 of Hydronic
Heating Capacities table.
INDOOR UNIT FAN PERFORMANCE DATA — 0.0-1.2 ESP
LEGEND
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.
