4.11.4 Protecting cooling water ducts
Protecting the cooling-water ducts during storage
The cooling water ducts are not filled with cooling water when the motor is supplied. To avoid
corrosion, the cooling water ducts are treated with a rust protection agent in the factory.
NOTICE
Corrosion
If the cooling water has been drained, you must flush the cooling circuit with a rust protection
agent if the motor is going to sit idle for a long period of time.
Otherwise material damage will occur.
NOTICE
Foreign bodies in the cooling circuit
Foreign bodies in the cooling system can cause blockages in individual circuits. Water-cooled
components can overheat and the motor fails.
● Ensure that no foreign bodies can enter the cooling system.
● Do not remove the protective cover until you are ready to make the final water connections.
NOTICE
Temperatures below 0 °C
Damage may be caused to the cooling circuit if the cooling water freezes at temperatures
below 0°C. Drain the water from the cooling system before you transport and store the motor.
● Drain the cooling water ducts.
● Blow out the cooling water ducts with compressed air.
4.11.5 Transporting a motor that has already been in operation
If you have already operated the motor and now want to transport it, proceed as follows:
1. Allow the motor to cool down.
2. Remove the connections provided by the customer.
3. Drain the cooling-water system and purge it carefully with air.
4. Fit the rotor shipping brace, if present.
5. Only use the eyebolts on the bearing shields - for example - to transport and lift the motor.
