4. Coat the tip of the new thermocouple with heat trans-

ferring paste (see chapter „5.3.1 Tools and operating

materials“) and insert it into the bore in the nozzle as far

as it will go.

Picture 61: Installation of the new thermocouple

5. Bend the thermocouple carefully and wind it along the

heater. At the same time slide the protective tube over

the pressure tube to fix the already positioned part of the

thermocouple.

6. Check functioning of the new thermocouple by heating

up the nozzle with a controller.

7. For notes for installation of the nozzle please refer to

chapter „5.5 Installation of L2X Drop-in hot runner sys-

tems“.
