System example
* SANYO makes it possible to link outdoor unit
together for a large capacity (48HP).
Since all pipings are concentrated
into one pipe shaft, you can minimize
piping space and construction labor

System limitations
*If the additional installment of outdoor and indoor units
are expected, the size of refrigerant piping should be
decided according to the total capacity after the addition.
*1 The connection between the indoor unit(s) and the solenoid
valve kit(s) has three (3) types of methods. For further details,
refer to the Section 2. 3-4. "Connecting Multiple Indoor Units
to a Single Solenoid Valve Kit".

If indoor/outdoor units need servicing, a ball
valve (optional) cuts off non-operational
units to let other units stay running.
If your indoor capacity load
changes in the future, it’s easy to
add on both indoor and outdoor
units using the same pipings.
