7 Periodic maintenance work / 7.2 Cleaning the compressor during op-
eration
7.2.3 Cleaning method
Cleaning method and operating state
The compressor is cleaned during operation using the wet cleaning method. This is carried
out at an engine load of 50 ... 85%.
This cleaning method is tested and approved by Turbo Systems.
V-engines
On V-engines with several turbochargers per engine, parallel cleaning of both turbochargers
is recommended. This cleaning process is faster and reduces the risk of surging of the tur-
bocharger.
Sequential charging
With sequential charging, it must be made sure especially after operating periods in the
lower range of performance that both turbocharger compressors are cleaned.
7.2.4 Function and safety of wet cleaning
CAUTION
Volume of water
Uncontrolled volumes of water can damage the turbocharger and the en-
gine.
Never connect the water connection directly to a water pipe or a bigger
u
metering container than the one specified by Turbo Systems.
WARNING
Danger due to pressure vessels
Personal injury can occur if the locally applicable legal regulations on peri-
odic inspections of the pressure vessels are not complied with.
The locally applicable legal regulations regarding periodic checks of the
u
pressure vessels must be observed.
Do not use pressure vessels that are defective.
u
CAUTION
Corrosion and deposits when cleaning
Salt water and cooling water treatment substances damage and adversely
affect turbocharger parts.
Never use salt water, but only pure water for cleaning.
