Cleaning and maintenance
Danger to life if blower is destroyed as a result of imbalance.
Imbalance and vibration on the motor’s bearings may destroy the blower and lead to personal injury and damage to surrounding building components. Check the vibration characteristics of the blower on a regular basis (ISO 14694). A sudden change of vibration levels may indicate that an inspection/maintenance is urgently needed.
Overheating and damage to units resulting from stopping at temperatures >60 °C
In no circumstances should you stop the blower before the air medium inside it has reached a temperature of <60 °C. This will protect the motor from damage caused by overheating. If this temperature cannot be guaranteed, external cooling systems must be used. If the temperature inside the blower increases while it is idle, the operator must wait for the temperature to fall to below 60 °C before restarting.
