Every 6 months, the following measures are required:
Check the hygrometer (02) in the sight-glass. There is an opening (01) in the wooden
u
crate which allows this check to be carried out. When the display field has changed colour
at the 70% level, the maximum permissible humidity has been exceeded. In this case, the
turbocharger must be inspected by an ABB Turbocharging Service Station and repacked.
Inspect the package for damage. If the package is damaged, the turbocharger must be in-
u
spected by an ABB Turbocharging Service Station and repacked.
After every 3 years the following work steps must be performed by an ABB Turbocharging
Service Station:
¡
Inspect the component
¡
Replace the desiccant agent
¡ Repackage the component.
If the 70% field of the hygrometer (02) has not changed colour and the package is undam-
aged, the turbocharger can be put into operation without any prior inspection by an ABB
Turbocharging Service Station.
Unpacking the turbochargers
The corrosion protection effect ends after the material is unpacked from the VCI package.
To avoid the formation of condensation, the surroundings and the content of the package
must have the same temperature during unpacking.
