5.1  Opening the unit housing 

As part of standard servicing and maintenance it may be necessary to open the unit housing and 
covers. The unit allows easy access to all main components: 

5.1.1  To open the electrical cabinet 

▪

  Release the locks located on both sides of the electrical cabinet and lift the cover. 

 

Figure 33: Position of the locks 

5.1.2  To open the compressor chamber 

▪

  Unscrew  the  two  screws  located  on  the  top  of  the  compressor  chamber  cover,  unplug  the 

green/yellow grounding cable by pulling, then lift the cover.

5.1.3  To remove the fan safety grid 

▪

  The grid can be removed only when the unit is turned off. 

▪

  To remove the grid, unscrew the six screws securing the grid and lift it off.
