Air handler capacity data notes
• Rated in accordance with DOE test procedures (Federal Register 12-27-79 and 3-18-88) and
ANSI/AHRI Standard 210/240.
• The cooling MBH is based on 80°F entering air temperature, 50% relative humidity (RH), and
rated airflow.
• The energy efficiency ratio (EER2) is the total cooling output in BTUs at 95°F outdoor ambient
divided by the total electric power in watt-hours at those conditions.
• The seasonal energy efficiency ratio (SEER2) is the total cooling output in BTUs during a normal
annual usage period for cooling divided by the total electric power input in watt-hours during
the same period.
• A cell with no value means not applicable.
