gefran ILI Series Original Operating Instructions page 27

8.1. Maintenance
Melt pressure sensors must be installed and electrically connected by trained people, following all applicable recommendations, with
zero pressure and voltage, and with the machine switched off.
The sensor must be removed with the plastic in melt state and the machine in hot conditions.
Always remove the sensor before cleaning the machine, using steel brushes or similar tools.
Always wear protective gloves and always take adequate ESD precautions to prevent electrostatic discharges that could damage
the sensor.Always use the wrench for the hexagonal nut when installing and removing the sensor.
DO NOT force the electronics housing.
Once the sensor is removed, clean it gently with a soft cloth while the material is still malleable.
8.2. Transport, storage and disposal
The melt pressure sensors Impact series are realized with piezoresistive silicon technology completely "fluid free".
Even if these are designed with a thick diaphragm, they must be always transported and stocked with the protection cap and with
the package.
Gefran allows melt pressure sensors of own production, also defective units or damage by the use, for the disposal.
