● Make sure that the condensation can always drain away freely.
● The plug that has been inserted into the water drain holes allows the condensation to drain
away. Do not remove the plug, otherwise the machine's degree of protection will be affected.
● If you have any questions, contact the Siemens Service Center (Page 131).
NOTICE
Damage caused by condensation
If the stator winding is damp, its insulation resistance is reduced. This results in voltage
flashovers, which can destroy the winding. Condensation can also cause rusting inside
the machine. Make sure that the condensation can always drain away freely.
