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 is
made 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 mumber of connectable indoor units
Indoor/outdoor unit capacity ratio
Maximum actual tubing length
Maximum level difference (when outdoor unit is lower)
Maximum total tubing length

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.
