NOTE: Use Sensible Heat correction factors when calculating heating capacity.

DIRECT EXPANSION (DX) CORRECTION FACTORS

% OF	CORRECTION FACTOR
NOMINAL CFM	Total	Sensible
80	0.95	0.93
90	0.97	0.96
100	1.00	1.00
110	1.02	1.04
120	1.05	1.08

Consult factory for values outside of table.

DX Total Capacity (MBtuh) = Base Et x Total Correction Factor

DX Sensible Capacity (MBtuh) = Base Es x Sensible Correction Factor

%of Nominal Cfm = Actual Cfm (from Fan Performance table) ÷ Nominal Cfm

NOTES:

1.Leaving air temperature not to exceed 104 F with standard motor.

2.Base capacity ratings based on 180 F entering water temperature and 70 F entering air temperature.

3.Hot Water Heating Capacity (MBtuh) = Rated Heating Capacity x Hot Water Capacity Correction Factor x Sensible Airflow Correc- tion Factor.
