6 Periodic maintenance
6.4.3 Principle of wet cleaning
Principle of wet 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.
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.

Volume of water
Uncontrolled volumes of water can damage the turbocharger and the en-
gine.
CAUTION
Never connect the water line without the orifice specified for the turbo-

charger.
