Table 1—MIN/MAX AIRFLOW
The indoor airflow delivered by this system varies significantly
based on outdoor temperature, indoor unit combination, and
system demand. The air flows 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 air flows can be adjusted from these
numbers in the Infinity Control Heat Pump Setup screen.
