8.2 Switching off the anti-condensation heating
Faults in operation
Deviations from normal operation such as increased power consumption, temperatures or
vibrations, unusual noises or odors, tripping of monitoring devices, etc., indicate that the
machine is not functioning properly. This can cause faults which can result in eventual or
immediate death, serious injury or material damage.
● Immediately inform the maintenance personnel.
● If you are in doubt, immediately switch off the motor, being sure to observe the system-
Risk of corrosion due to condensate
Humid air can condense inside the machine during operation as a result of intermittent duty
or load fluctuations. Condensate can collect inside the motor. Damage such as rust can result.
Make sure that any condensation can drain away freely.
Switching off the anti-condensation heating
Excessive machine temperature
If the anti-condensation heating is operated while the machine is running, this can increase
the temperatures inside the machine. This can result in material damage.
● Make sure that the anti-condensation heating is switched off before the machine is
● Only operate anti-condensation heating when the machine is switched off.
