E2 Freeze Protection
Freeze protection is a normal protection, but not an abnormal malfunction. If freeze protection occurs
frequently during operation, check if the indoor lter is blocked with dirt and debris, or check if the indoor air
outlet is abnormal. The user must clean the lter and check the air outlet and air return pipe periodically to
ensure smooth operation.
