Manual defrost should be done as follows.

Change the DIP SW1-1 on the outdoor controller board from OFF to ON.
2
Manual defrost will start by the above operation
1
if these conditions written below are satisfied.
• Heat mode setting
• 10 minutes have passed since compressor started operating or previous manual defrost finished.
• Pipe temperature is less than or equal to 8°C.
Manual defrost will finish if certain conditions are satisfied.
Manual defrost can be done if above conditions are satisfied when DIP SW1-1 is changed from OFF to ON.
After DIP SW1-1 is changed from OFF to ON, there is no problem if DIP SW1-1 is left ON or changed to OFF again.
This depends on the service conditions.
*2
"Power failure automatic recovery" can be set by either remote controller or this DIP SW. If one of them is set to ON, "Auto recovery" activates. Please set "Auto
recovery" basically by remote controller because all units do not have DIP SW. Please refer to the indoor unit installation manual.
