Dismantling the diffuser and the wall insert 

 

Figure 33: Dismantling the diffuser and the wall insert 

1.  Loosen the screws (79041) and remove with fixing discs (79040). 
2.  Remove diffuser (79000). 
3.  Fit the swivel lifting eye (S) to the wall insert (77000). Secure lifting gear to the swivel lifting 

eye. 

4.  Remove the wall insert (77000). When doing this, make sure that the wall insert does not 

"stick" to the compressor casing (72000). 

5.  Remove and dispose of the O-ring (77005).
