Defrosting

When the outdoor air temperature is very low and humidity is very high, frosting will occur to the heat exchanger of the outdoor unit, which has negative impacts upon the efficiency of the heating performance. In such case, the automatic defrosting function will come into play. The heating operation will be stopped for 5-10 minutes to do the defrosting.

  • The fans of both the outdoor and indoor units are stopped.
  • During the defrosting, the outdoor unit might generate some steam. It is caused by fast defrosting, which is not a performance failure.
  • Upon the completion of the defrosting process, the heating operation is resumed.
