Initial start-up
Only turn on if the heated length is completely covered by the medium.
It is advisable provided an on-site level monitoring.
The connection head should not be isolated, otherwise the connection area can be
overheated.
Max. permissible temperature at the connection area: 80°C.
In a closed system, a pressure relief valve must be installed on site.
Please make sure to have closed the connection head properly.
Please make sure that the device is covered by the medium according to the requirements.
Set a temperature controller to the target temperature.
Guarantee that the temperature controller is duly attached.
Guarantee that the on-site temperature limitation is duly attached.
By a temperature limitation the medium and the device are protected against to high temperatures.

Repair of failures
The work described below must be executed by an electrical engineer only.
Failure:
Device does not heat up
Repair:
- Check fusing
- Control the supply voltage
- The temperature of the temperature controller is set too low.
Set temperature controller to the correct temperature.
- The on-site temperature-limiter switched off circuit.
Check reason, remove fault, reset temperature limiter.
Run the initial start-up procedure for the device after each repair of failures.
