6.1.4 Quick defrost
You can start a defrost without changing the interval set on the controller.
If the gasket is damaged or the delivery door remains open too long (for example is
blocked by an object) the hot air enters into the cold store thus creating ice above the
evaporator which blocks the passage of air.
To solve the problem you need to initiate an additional defrost action that may be
performed in a few steps:
To start the defrost press and hold for 3 seconds the button 3 "DOWN". To stop the
process, press again the button 3 "DOWN".
