Information for multi system air conditioner (Outdoor unit: MXZ series)
Multi system air conditioner (Outdoor unit: MXZ series) can connect two or more indoor units with one outdoor
unit. According to the capacity, two or more units can operate simultaneously.
• When you try to operate two or more indoor units with one outdoor unit simultaneously, one for the cooling and the other
for heating, the operation mode of the indoor unit that operates earlier is selected. The other indoor units that will start the
operation later cannot operate, indicating an operation state. (Refer to the table of Operation Indicator lamp on page 6.)
In this case, please set all the indoor units to the same operation mode.
• When indoor unit starts the operation while the defrosting of outdoor unit is being done, it takes a few minutes (max. 10
minutes) to blow out the warm air.
• In the heating operation, the indoor unit that does not operate may get warm or the sound of refrigerant flowing may be
heard. This is not a malfunction since the refrigerant continuously flows into the indoor unit that does not operate.
