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 compressor stage can be adjusted from these numbers in the Observer® Control Heat Pump 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. Ductwork 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 duct
work restrictions have caused the blower to cut-back.
