The frequency of the cleaning intervals depends on the local degree of fouling.
NOTICE
Damage to the machine
Material damage can occur if you direct compressed air in the direction of the shaft outlet or
machine openings.
● Avoid pointing compressed air directly onto shaft sealing rings or labyrinth seals of the
machine.
9.2.14 Drain condensate
If there are condensation drain holes present, open these at regular intervals, depending on
climatic conditions.
WARNING
Hazardous voltage
The winding can be damaged if objects are introduced into the condensation holes (optional).
This can lead to death, serious injury or material damage.
Note the following to maintain the degree of protection:
● Switch off the machine so that it is in a no-voltage condition before you open the
condensation drain holes.
● Close the condensation drain holes, e.g. using T-plugs, before commissioning the
machine.
NOTICE
Reduction of the degree of protection
If condensation drain holes are not closed, then this can result in material damage to the motor.
In order to maintain the degree of protection, after the condensation has been drained, you
must close all of the drain holes.
9.2.15 Touch up any damaged paintwork
If the paint is damaged, it must be repaired in order to protect the unit against corrosion.
Note
Paint system
Contact the Service Center (Page 153) before you repair any damage to paint. They will provide
you with more information about the correct paint system and methods of repairing paint
damage.
