1 Decrease the engine power to approximately 45%.
2 Make sure that compressed air is available at the shut-off valve (001, Figure 9-2) and
fresh water is available at the shut-off valve (009).
NOTE: The schematic diagram in Figure 9-2 is an example and is used for reference.
Some parts can look different.
3 Fill the tank (006, Figure 9-2) through the funnel (008) with fresh water and the specified
quantity of cleaning fluid (max. 30 liters).
3.1 Open the vent valve (002) and the valve (007) of the tank (006).
3.2 Carefully open the shut-off valve (009) in the water supply pipe and fill the
tank (006).

with fresh water to put into the funnel. When you use this method,
make sure that the shut-off valve in the supply pipe stays closed.
3.3 Close the shut-off valve (009) in the water supply pipe.
3.4 Close the vent valve (002) and the valve (007) of the tank (006).
4 Open the shut-off valve (001) in the compressed air supply pipe to pressurize the
tank (006).
5 Clean the scavenge air cooler (005) as follows:
5.1 Open the shut-off valve (003).
5.2 After no more cleaning water comes out, close the shut-off valve (003).
6 Close the shut-off valve (001) in the compressed air supply pipe.
7 Open the vent valve (002) to release the pressure in the tank (006).
8 After 10 minutes, do Step 2 to Step 7 again with fresh water (no cleaning fluid).
9 Do a check of the water separator for dirt.
