6 Periodic maintenance
Principle of wet cleaning
Corrosion and deposits when cleaning
Salt water and cooling water treatment substances damage and adversely
affect turbocharger parts.
CAUTION
Never use salt water, but only pure water for cleaning.

To clean the compressor stage during operation, water is injected before the compressor
wheel.
The water does not act as a solvent. The coating is removed by the mechanical action of the
impacting droplets. The process is particularly suitable as long as the contamination is not too
advanced.
Cleaning several turbochargers
If several turbochargers are installed on an engine, it is recommended to clean one compres-
sor after the other.
Volume of water for cleaning the compressor
Uncontrolled volumes of water can damage the turbocharger and the en-
gine.
CAUTION
Do not guide water pipes to the filler openings.
