For the measures always necessary for preparing the turbocharger parts for mothballing,
see section Taking the engine out of operation for up to 12 months, subsection Preparations
for mothballing.
If the turbocharger remains attached to the engine, see section Taking the engine out of op-
eration for up to 12 months, subsection Rotor turning in stack draught.
If the complete turbocharger is removed or the turbocharger is assembled again from the
individual parts:

Only dry rooms with 40 ... 70 % atmospheric humidity, in which no water condensation can
form, are suitable as storage locations.
