Easy, Flexible Installation for All Housing Types

Save space with the wall-mounted or floor-standing type indoor unit which includes a water tank. Able to be fitted in a wide range of homes, its pipes extend up to 50 meters and can be flexibly and neatly connected. The Split can also be installed farther away from your property for more complex installations. Plus, the outdoor unit is smaller than the Monobloc, making installation easier and shorter with integrated hydronic components included in the indoor unit.

Its two units are only connected by refrigerant piping, so hydronic components are located safely within the indoor unit. No matter how cold it gets out, the unit won't be compromised by freezing thanks to its Split nature.
