After cleaning, wait at least 5 minutes to allow turbocharger to dry.
NOTICE
If the cleaning operation is not satisfactory, it may be repeated up to
two times.
If the cleaning result is still not satisfactory after three attempts and
the engine values are also unsatisfactory, we recommend that you have
the turbocharger inspected and cleaned by an official ABB Turbochar-
ging Service Station.

5.4 Cleaning turbines and guide vanes during
operation
NOTICE
HFO applications
The TPL65VA.. has not been released for HFO applications. Wet clean-
ing of the turbine blades and guide vanes during operation is thus
neither required nor planned.
5.5 Cleaning components mechanically
5.5.1
Introduction
Compressor wheels can be heavily contaminated by badly filtered intake
air, as can turbines by heavy fuel oil operation or coked oil. Such contam-
ination may possibly no longer be removed through cleaning during op-
eration and must be cleaned mechanically during the standard service in-
tervals (see chapter entitled Service work).
Professional overhauling of the components by an ABB Turbocharging
Service Station is required, preferably using the cleaning method de-
scribed in the following.
