7.2.3 Prerequisites for wet cleaning of compressor
¡ Engine load of 50 ... 85%
CAUTION
Volume of water
Uncontrolled volumes of water can damage the pressure stages and the en-
gine.
u Never connect injection tubes directly to a water pipe or a larger meter-
ing container other than that specified by Turbo Systems.
CAUTION
Corrosion and deposits when cleaning
Salt water and cooling water treatment substances damage and adversely
affect parts of the low-pressure and high-pressure stage.
u Never use salt water, but only pure water for cleaning.

pure water.
u Screw in sealing plug (27005) again.
u Push the valve activator(03) against the spring and hold for 10…15seconds until the
whole volume of water is injected.
u Continue to operate the engine for at least five more minutes to dry the compressor
stage.
The cleaning process can be repeated up to three times.
The success of the cleaning can be recognised based on the charging pressure or the ex-
haust gas temperature.
