NOTE
■
When installing a multi outdoor system:
•
with 2 units: BHFQ23P907 outdoor unit multi
connection piping kit is required.
•
with 3 units: BHFQ23P1357 outdoor unit multi
connection piping kit is required.
■
There are restrictions on the refrigerant pipe
connection order between outdoor units during
installation in case of a multiple outdoor unit
system.
Install according to the following restrictions.
The capacities of outdoor units A, B, and C must
fulfill the following restriction conditions: A
≥
B
≥
C.
■
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.
