3. PLASMA DEODORIZING/PLASMA AIR PURIFYING power operation check

PLASMA DEODORIZING/PLASMA AIR PURIFYING power goes ON when PLASMA button on the remote controller is pressed once while the indoor error indication is being checked or after one short beep sound (signal reception beep) is emitted. PLASMA button is pressed, the power of plasma is changed in sequence:

PLASMA DEODORIZING power goes ON PLASMA AIR PURIFYING power goes ON Cancel

Check the operation display section of the remote controller to confirm that PLASMA DEODORIZING power or PLASMA AIR PURIFYING power is activated.

While PLASMA/WASH lamp stays OFF, and it means normal.

Flashing PLASMA/WASH lamp means abnormal, and the plasma power is not being conducted.

PLASMA/WASH lamp

Action

 

 

Continuously flashes

Follow "Check of PLASMA DEODORIZING power" or "Check of PLASMA AIR PURIFYING power"

to identify the error.(Refer to 9-6.For G.)

 

2-time flash

PLASMA DEODORIZING power or PLASMA AIR PURIFYING power control circuit on the indoor

electronic control P.C. board is out of order.(Refer to 9-6.For G.)

 

NOTE: Perform the above mentioned check with the front panel closed. Panel open is detected by the SAFETY DEVICE (PLASMA UNIT).
