Use the specied refrigerant only
Never use any refrigerant other than that specified.
Doing so may cause a burst, an explosion, or fire when the unit is being used, serviced, or disposed of.
Correct refrigerant is specified in the manuals and on the spec labels provided with our products.
We will not be held responsible for mechanical failure, system malfunction, unit breakdown or accidents caused by
failure to follow the instructions.
TECHNICAL CHANGES

These models are compatible with the outdoor units with low standby power control.
Connecting these models to the MUZ-LN·VG-series outdoor units enables the low standby power control. Refer to the techni-
cal guide about the low standby power control.
These models may be connected to the MUZ-LN·VG series after once connected to the MXZ series and operated, for exam-
ple because of relocation. In that case, the MUZ-LN·VG series outdoor units will not operate without taking a step. Follow the
procedure "Deleting the memorized abnormal condition" described in 10-2.1.
Revision A:
• For Wi-Fi interface, 10. TROUBLE SHOOTING has been modified.
