Start by setting the main switch (part 1) to 

the "0" position.

Disconnecting from the power outlet

In case the machine is connected through 

the  plug  (part  24),  make  sure  that  the 

switch  (part  23)  is  also  in  the  Off  posi-

tion before disconnecting. Disconnect the 

motor  pump  (part  15)  by  pulling  out  its 

special plug (part 25).

Shut  off  the  water  supply  by  closing  the 

specific tap located upstream of the puri-

fier inlet. Disconnect the water pipe at the 

purifier  (part  17)  inlet,  which  is  located 

just  downstream  of  the  special  tap  (part 

18), which has been closed in advance.

(part 19).
At  this  point,  the  machine  may  be 

removed from the bar, being very careful 

not to drop it.

rials and therefore, if you do not intend to
