Procedure for method with short water injection time
 Prerequisites have been fulfilled.
 Wait 10 minutes during a stabilising phase after reducing the engine
load.
 Open the shut-off valve.
 Set the required water flow rate as specified in the table of cleaning
parameters using the flowmeter and inject for 30 seconds.
 Observe a pause of 3 or 5 minutes as specified in the table.
 Repeat the 30-second water injection two times.
 Close the shut-off valve.
 Wait 10 minutes during a stabilising phase before increasing engine
load again.
This completes the turbine cleaning process.

CAUTION
Maximum temperature in front of turbine during cleaning
When cleaning, the temperature in front of the turbine will rise and can
heavily stress the material of turbine components. The temperature at
the turbine inlet can be up to 100 °C higher than the exhaust gas
temperature after the cylinder. This should be taken into consideration
when setting the operating point before cleaning.
 Don't exceed maximum temperature in front of turbine when
cleaning.
