1 Introduction
Long-term storage of replacement turbochargers or spare parts
If requested in the purchase order, the turbochargers or cartridge groups will be prepared for
long-term storage. The package is equipped with a hygrometer (see illustration).
Figure 3: Package with hygrometer
Every 6 months, the following measures are required:
Check the hygrometer (02) in the sight-glass. There is an opening (01) in the wooden crate

to enable you to perform this check. If the 70% indicator field has changed colour, the
maximum admissible atmospheric humidity has been exceeded. In this case, the turbo-
charger or cartridge group must be checked and repackaged by an ABB Turbocharging
Service Station.
Check the package for damage. If the package is damaged, the turbocharger or cartridge

group must be checked and repackaged by an ABB Turbocharging Service Station.
After every 3 years, the following steps must be carried out by an ABB Turbocharging Service
Station:
 Checking the component
 Replacing the desiccant
 Repackaging the component.
Replacement components which are ready for operation
If the 70% field of the hygrometer (02) has not changed colour and the
package is not damaged, the replacement turbocharger or replacement car-
NOTICE
tridge group can be put into operation without previously having been
checked by an ABB Turbocharging Service Station.
Unpackaging replacement turbochargers or spare parts
Once the material has been unpackaged from the VCI package, the corrosion protection is no
longer effective.
To prevent condensation, the temperature of the package contents must be the same as the
ambient temperature.
