Operational procedure

The plasma electrode unit might be abnormal. Confirm if plasma electrode unit is abnormal according to the following procedures.

Confirm that the remote controller is in the failure mode recall function.

With the remote controller headed towards the indoor unit, press TOO COOL or TOO WARM button to adjust the set temperature to 23 :. W1

W1. Regardless of normal or abnormal condition, a short beep is emitted as the signal is received.

 

Does POWER lamp on the indoor unit blink at the

Blinks: The plasma electrode unit is abnormal.

 

 

 

 

 

Beep is emitted at the same timing as the

Releasing the failure mode recall function

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

Release the failure mode recall function by the following procedures. Turn OFF the power supply and turn it ON again.

Press RESET button of the remote controller.

Release the failure mode recall function according to the left mentioned procedure.

Repair the defective parts.

Deleting the memorized abnormal condition

1After repairing the unit, recall the failure mode again according to "Setting up the failure mode recall function" mentioned above.

2Press OPERATE/STOP(ON/OFF) button of the remote controller (the set temperature is displayed) with the remote controller headed towards the indoor unit.

3Press EMERGENCY OPERATION switch so that the memorized abnormal condition is deleted.

4Release the failure mode recall function according to "Releasing the failure mode recall function" mentioned above.

NOTE1. Make sure to release the failure mode recall function once it's set up, otherwise the unit cannot operate properly. 2. If the abnormal condition is not deleted from the memory, the last abnormal condition is kept memorized.
