ADDITION
CONCENTRATION
If indoor/outdoor units need servicing, a ball
valve
(
field supply
)
cuts off non-operational
units to let other units stay running.
* The capacity after the setting
must not exceed 48 PS.
Since all tubings are
concentrated into
one pipe shaft, you
can minimize piping
space and construc-
tion labor
Maximum number of combined outdoor units
Maximum horsepower of combined outdoor units
Maximum number of connectable indoor units
Indoor/outdoor unit capacity ratio

)

CONNECTION
If your indoor capacity load
changes in the future, it’s easy to
add on both indoor and outdoor
units using the same tubing.
*If additional installation of outdoor and indoor units is
expected, the size of refrigerant tube should be decided
according to the total capacity after the addition.
Combination of outdoor units
The DC inverter unit can be used independently or in combination.
CAUTION
R407C models and R22 models must not be used in combination with each
other.
