Easy installation work
Multiple indoor units can be connected to one outdoor unit. As a result, piping and wiring work becomes as easy as when
arranging just one refrigerant system. The installation work is made easier and with a shorter schedule, in comparison
with the single type where an outdoor unit is required for each indoor unit.
Easy and shortened installation schedule become possible because four indoor units can be connected to one refrigerant
system.
This helps to save more installation space and so increases flexibility in installation location.
