Maximum temperature at turbine inlet during cleaning
During cleaning, the temperature at the turbine inlet will rise and may strain
the material significantly.
CAUTION
Make sure the maximum temperature at the turbine inlet is not exceeded

during cleaning.

Fulfil prerequisites.

Ensure that the water supply (01) is guaranteed.

Open the stop valve (02) and set the water volume flow V

cleaning parameters).
Close the stop valve (02) after 10 minutes.

Wait for 10 minutes; do not change the load during this stabilisation phase.

If the cleaning result is unsatisfactory or there is water leakage, contact an ABB Turbocharg-
ing Service Station.
