see section Taking the engine out of operation for up to 12 months, subsection Preparations
for mothballing.

, subsection Rotor turning in stack draught.
If the complete turbocharger is removed or the turbocharger is assembled again from the
individual parts:
u
Seal all openings of the turbocharger with paraffin paper and wooden lids.
Only dry rooms with 40 ... 70 % atmospheric humidity, in which no water condensation can
form, are suitable as storage locations.
