5. Reattach the rotor shipping brace, if present.
6. Pack the machine again.
4.14.7 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. The cooling circuit is protected with an anti-corrosion emulsion.
Protecting the cooling circuit against corrosion
You protect the cooling circuit against corrosion when the machine has already been in
operation and is then placed in storage or put out of operation.
1. Completely drain the cooling ducts. To be completely certain, use compressed air to clean
the cooling water ducts so that they are completely empty.
2. Flush the cooling water ducts with a corrosion-protection emulsion to avoid the buildup of
rust.
4.14.8 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 anti-corrosion compound which provides long-term protection, e.g.
Tectyl 506.
● Inspect the machine regularly and apply an additional coating of corrosion protection if
necessary.
Document all preservation measures taken so that they can be reversed before the machines
are put back into service.
