NOTICE
To ensure long life and continued flawless operation of the actuator, we recommend using a service
medium that complies with the requirements of classification 21/18/13 pursuant to ISO 4406.
The coolant should be properly modified e.g. filtered water with an anti-corrosion and frost proof agent.
After switching off the Hot Runner heater, the cooling for the actuator should remain on for at least
15 minutes, to avoid damage to the Actuator seals and the position sensor.
