Defrosting will be performed about once an hour when frost forms on the heat exchange of the outdoor unit,
for 5~10 minutes each time.
During defrosting operation, the operation lamp blinks in cycle of 3 seconds on and 0.5 second off.
The maximum time for defrosting is 20 minutes.
(If the piping length used is longer than usual, frost will likely to form.)
