Prepare the proper tools.

Prepare the proper protectors.

Provide adequate ventilation.

After stopping the operation of the air conditioner, turn off the power-supply breaker and remove the power plug.

Discharge the capacitor before the work involving the electric parts.

Do not perform the work involving the electric parts with wet hands.

Do not pour water into the electric parts.

Do not touch the refrigerant.

Do not touch the hot or cold areas in the refrigeration cycle.

When the repair or the inspection of the circuit needs to be done without turning off the power, exercise great caution not to

touch the live parts.

Use the speciﬁed 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.

Revision A:

• Airflow in the Silent mode in the cooling operation has been changed.

• "TROUBLESHOOTING" has been corrected (10-2, 10-4).

1. New model

The following models are compatible with the outdoor units with low standby power control.

Connecting the following models to the MUZ-EF·VE(H) series outdoor units enables the low standby power control. Refer to

the technical guide (OBT17) about the low standby power control.

The following models may be connected to the MUZ-EF·VE(H) series after once connected to the MXZ series and operated,

for example because of relocation. In that case, the MUZ-EF·VE(H) series outdoor units will not operate without taking a step.

Follow the procedure "Deleting the memorized abnormal condition" described in 10-2.1.
