10.2 Installation Process

 Make sure that the sealing surface is clean before installation and remove the
protective cover only when installing. If the sealing surface is damaged, replace
the device or adapter sleeve.
 Install or weld the adapter sleeve onto the container/pipe. For the welding
operation, please refer to "SISB Welding Adapter / Thread Adaptor Operating
Instructions".
 For installation of the tri-clamp, follow the relevant provisions for additional
installation steps.
 Attach the seal to the sensor through the thread lock sleeve. The seal must be
correctly positioned and locked. Close the gap between the sensor and the
adapter sleeve end face.
 Use the seal supplied with the sensor only. An inappropriate seal may cause
installation errors.
- The seal is too thick: A gap exists between the sensor tip and the adapter
sleeve.
- The seal is too thin: The seal is insufficiently compressed between the
sensor and the adapter sleeve. Leakage may occur.
