Air Flow Inspection:
• For proper cooling operation, the airflow through the indoor coil should be between 350 and
450 CFM per ton of cooling capacity (or 350 – 450 CFM per 12,000 BTU/HR) based on the
rating of the outdoor unit.
• If the outdoor unit is smaller than the maximum cooling capacity rating for the air handler, the
cooling capacity may need to be changed. Refer to section “8.3 Controller Input Options” for
more information.
• The proper cooling or heat pump tons is to be selected (see section “8.3 Controller Input
