of the coolant liquid is included
between the min. valve and the

antifreezing liquid.
The control must be performed
when the machine is cold and
switched off.
7.6 REPLACING THE PTFE AND THE RUBBER
Replacing PTFE
• Remove the worn PTFE 1.
• Accurately clear the rubber using a detergent.
• Apply the new adhesive PTFE strips in a linear and flat manner, making sure that, where they
meet, the edges match.
Be extremely careful not to touch or make dirty the adhesive side of the PTFE strips
during application.
Replacing the rubber
• Remove the worn rubber 2.
• Accurately clean the housing.
• Put a few drops of glue or
biadhesive tape on the side of
the rubber to be glued at the
bottom of the run channel.
• Put in the new rubber in a
linear way without pressing it
or pulling it in its length.
• Apply the PTFE as explained
in the previous paragraph.
