NOTE(S):
a. If calculating static pressure for a 48 Series unit, be sure to add gas heat pressure drop from Component Pressure Drop table.
b. Fan performance is based on wet coils and clean 2 in. filters.
c. See Component Pressure Drop data table before using Fan Performance tables.
d. To convert bhp to kW, use the formula:

Kilowatts = bhp x 0.746
Motor efficiency
See Physical Data table for motor efficiency.
