MIN/MAX AIRFLOW TABLES
The indoor airflow delivered by this system varies significantly based on outdoor temperature, indoor unit combination, and
system demand. The airflows on these tables are for duct design considerations. Duct systems capable of these ranges will
ensure the system will deliver full capacity at all outdoor temperatures.
Minimum and maximum airflows can be adjusted from these numbers in the Observer® Control Setup screen.

LEGEND::
Max Capacity Airflow - Stage 5 airflow varies depending on conditions. This is the highest airflow the system will attempt to deliver in this particular mode. Duct
work for non-zoned systems should be sized for this airflow to ensure the system can deliver full capacity when needed. Improper duct design may result in
excessive airflow noise and/or cutback occurrences at max airflow conditions.
Highest Min. Capacity Airflow - Stage 1 airflow also varies depending on conditions. In zoned systems, each zone must be capable of delivering this airflow for
the system to deliver full capacity into the zone. Otherwise, airflow may be diverted to other zones or cutback may occur.
Min Cooling (Dehum or Zoning) - Lowest airflow the system will deliver. May operate down to this airflow in dehumidification mode or in zoning applications
where ductwork restrictions have caused the blower to cut-back.
