Initiating a Manual Defrost

With the unit On/Off switch ON:

  1. Press the DEFROST key.

    • If the unit operating conditions allow a manual defrost (e.g. evaporator coil temperature is less than 10 C [50 F]), the unit enters defrost as the Defrost LED turns ON.

    • If unit operating conditions do NOT allow defrost, the LCD message display shows “DEFROST NOT ACTIVATED”.

  2. The defrost cycle automatically terminates.
