Multipliers for determining the performance with other indoor sections.
NOTE: For dry bulb temperatures different than those listed (between 73-87 F), sensible capacity increases by 1060 BTUH per 1000 CFM per degree above the
listed temperature and decreases by 1060 BTUH per 1000 CFM per degree below the listed temperature.
