NOTE The table above shows the possible total capacity
and number of possible indoor units when
configured in a standard combination.
Refer to the service manual for more details when
using a configuration other than a standard
combination.
If the total capacity of the connected indoor units
exceeds the capacity of the outdoor unit, cooling
and heating performance may drop when running
the indoor units.
Refer to the section on performance charac-
teristics in the Engineering Data Book for details.
There are restrictions on the refrigerant pipe
connection order between outdoor units during
installation in case of a multiple outdoor unit
system.
