 nanoe-G check mode 
o  To enable nanoe-G check mode, during nanoe-G operation ON: 
 
 
 
o  If there is abnormal discharge, nanoe-G indicator blinks immediately. 
 
  Error detection control 
When nanoe-G indicator blinks, it indicates error listed below: 
o  nanoe-G connector at main PCB open 
 Judgment method 
  During nanoe-G operation, nanoe-G connector at main PCB is opened. 
 Troubleshooting method 
  Connect the connector or stop operation to cancel the blinking 
o  Abnormal discharge error 
 Judgment method 
  During nanoe-G operation, the nanoe-G system has abnormal discharge due to short-circuit caused 
by water or dust adhesion and so forth, with Lo-feedback voltage (at microcontroller). 
  When abnormal discharge occurred, every 30 minutes the unit supplies power to the nanoe-G 
system. 
  When abnormal discharge occurs for 24 times continuously, nanoe-G indicator blinks. 
o Troubleshooting method 
  Press nanoe-G button or OFF/ON button to stop the operation and check the nanoe-G connector at PCB. 
  After that, press nanoe-G button again to confirm the nanoe-G indicator do not blinks. 
  The 24 timer counter will be clear after 10 minutes of normal operation or when operation stops. 
o  Error reset method 
  Press OFF/ON button to OFF the operation. 
  Press AUTO OFF/ON button at indoor unit to OFF the operation. 
  OFF Timer activates 
  Power supply reset. 
 
o  nanoe-G breakdown error 
 Judgment method 
  Hi-feedback voltage (at microcontroller) supplied to the nanoe-G system when nanoe-G operation is 
OFF; nanoe-G breakdown error show immediately. 
  It is due to indoor PCB or nanoe-G high voltage power supply damage. 
  Operations except nanoe-G continue. Both Timer indicator and nanoe-G indicator blink.
