indoor units
NOTES: Test conditions are based on AHRI 210/240. One
indoor unit is turned off during low-speed testing under
the new test conditions. Systems actually exhibit higher
energy efficiencies during normal operation.

The charts below indicate the rated capacities for each of the
MXZ systems.
With the addition of ducted indoor units to the MXZ-Series, the number
of available combinations has greatly expanded. The installation speci-
fications and rated capacities vary on systems using wall-mounted only
(MSZ-A and/or MSZ-FD), ducted only or a combination of unit styles.
