If your indoor capacity load changes in the future,
it’s easy to add on both indoor and outdoor units
using the same piping.
*If the additional installment of outdoor and indoor units is
expected, the size of refrigerant piping should be decided
according to the total capacity after the addition.
If indoor/outdoor units need servicing, a ball
valve (optional) cuts off non-operational
units to let other units stay running.
* The capacity after the setting is
made must not exceed 32 PS.
Since all pipings are
concentrated into
one pipe shaft, you
can minimize piping

tion labor
