FOR MULTI SYSTEM AIR CONDITIONER (MSZ-GS06/09/12/15/18/24)
OUTDOOR UNIT: MXZ series
Multi system air conditioner can connect 2 or more indoor units with 1 outdoor unit.
• When you try to operate 2 or more indoor units with 1 outdoor unit simultaneously, 1 for the cooling and the others
for heating, the operation mode of the indoor unit that operates first is selected. Other indoor units cannot operate,
and operation indicator lamp blinks as shown in the figure below. In this case, please set all the indoor units to the

• 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, though indoor unit that does not operate may get warm or the sound of refrigerant flowing
may be heard, they are not malfunction. The reason is that the refrigerant continuously flows into it.
