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.
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.
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.
