1 FEATURES
1.SPACE-SAVING LAYOUT
Two or three indoor units are served by a single outdoor unit whose installation requires only minimum space. This allows
equipment installed outside the house to be arranged in a neat, space-saving layout.
2.FLEXIBLE INSTALLATION OF INDOOR UNITS
Each indoor unit can be connected to piping up to 65 feet in length, providing plenty of freedom in determining the best loca-
tions for installation.

3.AUTO-RESTART FUNCTION
The auto restart function restarts the equipment when power is
restored following an outage automatically. Operation resumes
in the mode in which the equipment was running immediately
before the outage.
HIGH PERFORMANCE ROTARY COMPRESSOR
The advanced design of Mitsubishi Electric’s powerful and ener-
gyefficient rotary compressor results in lower operating costs
and longer service life.
