Caution: before performing this 
operation verify that the machine is not 
hot so as to avoid burning!

Keep the unit steady by hand on the point “X” to 
avoid rotation, disconnect the PTFE hydraulic 
tubes by a simply clockwise rotation of the two 
quick couplings “A”, each tube contains washer 
and joint; unscrew the two heating connectors 
“B” with joint “C” by means of the 15 mm 
spanner “7”.

Caution: to remount the connector 
“B” it is important to apply it a 
clamping torque of MAX 2,5 N x mt   so 
as not to damage them.
They have to be tightened until the 
ring nut hits the heating plate and not 
more. If possible tighten by hand 
without the spanner.
