Dismantling/installation of the sensor on pump housing

Take into account the “Shutdown” section before dismantling/installing the sensor on the pump housing!

The sensor at the pump housing is used to measure temperature.

WARNING

Hot components!

Pump housing, motor housing and lower module housing can get hot and cause burns if touched.

• Allow the pump to cool down before commencing any work!

WARNING

Hot fluids!

There is a risk of scalding caused by escaping, hot fluid at high fluid temperatures and system pressure values.
Residual pressure in the pump between the shut-off devices may suddenly push the loose sensor out of the pump housing.

• Close shut-off device or drain unit!
• Follow the manufacturer’s instructions and safety data sheets for possible additives in the system!
