Warning

Before performing an overhaul, disconnect the power plug or power cable from the unit.

Performing the work with the power supplied to the unit, may cause an electric shock.

When repair work or circuit inspection that requires power supply for the air conditioner, is to be performed,

 

do not touch the charging section.

 

Doing so may cause an electric shock.

Prohibit

For the step-up capacitor attached to the electric section, perform the repair work after sufficiently discharging it. Insufficient capacitor discharge may cause an electric shock.

Do not perform repair work on the electric sections with wet hands.

Doing so may cause an electric shock.

Prohibit

Do not start or stop the air conditioner by means of connecting or disconnecting the power plug.

Doing so may cause an electric shock or fire.

Prohibit

When conducting repair work only use components included in the parts list for the corresponding unit and perform the work with the appropriate tools.

Incorrect or poor repair work may cause an electric shock or fire.

Never modify the unit.

Doing so may cause an electric shock or fire.

Prohibit

Perform all electric work according to local applicable regulations related to electrical equipment or interior wiring regulation and make sure to use the exclusive circuit.

Insufficient capacity to the electric circuit or defective arrangement results may cause an electric shock or fire.

Make sure to replace any power cable or lead wire showing any signs of scratch or deterioration.

Failure to do so may cause an electric shock, overheating or fire.

Make sure that there is no dust on or slack in the power plug and insert fully into the socket.

Dust or incomplete connections may cause an electric shock or fire.

Do not damage or process the power cord, as it may cause an electric shock or fire.

Prohibit

For the wiring between the indoor unit and outdoor unit, securely fix the specified cable onto the terminal plate. Poorly fixed wiring may cause a heat or fire.

After connecting the wiring between the indoor unit and outdoor unit, attach the terminal cover securely. Incomplete attachment of the terminal cover may cause overheating or fire.
