3. When stored for longer than two years, lubricate with twice the grease quantity in
accordance with the lubricant plate. This ensures that the grease is evenly distributed and
covers all surfaces. Corrosion damage is avoided.
NOTICE
Rolling bearing damage due to unchanged resting position
Roller bearings can be damaged when kept in the same or almost the same position.
● Every three months, manually rotate the rotor through five revolutions.
● Make sure that the resting position of the rotor after the rotor has been turned over is
different from its previous position. Use the feather key as a reference point, if present.
4. Replace the corrosion protection.
5. Reattach the rotor shipping brace, if present.
6. Pack the machine again.
4.15.6 Protection against corrosion
If the machine is stored in dry conditions, then apply the subsequently listed anti-corrosion
measures:
● Storage up to six months:
Apply a coat of corrosion protective compound to all accessible bare metal parts such as
the exposed shaft extension, flange or machine feet.
● Storage for longer than six months:
Apply a coat of long-term anti-corrosion agent to all accessible bare parts.
● Inspect the machine regularly and if necessary, apply an additional coating of corrosion
protection.
Document all preservation measures taken so that they can be reversed before the machines
are put back into service.
4.15.7 Protecting the cooling water circuit during storage
Anti-freeze protection
When supplied, the machine is not filled with cooling water, so that there is no risk of frost
damage.
