DEFROST  

 

In PRODUCTION and STORAGE, the machine periodically performs automatic defrost 

processes, with the aim of always maintaining the cabinet evaporator free of ice and for the 

cabinet cooling to work correctly.  

The defrost consists in the supply of hot gas in the cabinet evaporator. This function melts the 

ice and the consequent water is collected in the lower tray.  

 

The active outputs during the process are MC and EVRV. 

 

There are two types of Defrost: 

 

Automatic Defrost 

The  cabinet  has  a  timer  cycle  linked  to  a  cooling  process.  When  the  time  programmed  is 
reached in step Time Cab. x Defrost 

(T82), an automatic defrost activates for 140’’. Then, that 

timer goes down to zero.  

 

Safety Defrost 

Is performed the third time the timer reaches zero without the cabinet having reached the set 
temperature. 

If two Safety defrosts are performed without the cabinet having reached the set temperature, 
the display will show the message "

Manual Cleaning

" (see alarm).
