Operation
Risk of skin burns in the vicinity of the fan caused by hot air medium, hot motor or hot housing. There is a danger to life near high-temperature fans with airstream temperatures of up to 200 °C.
Before working on the fan, wait until it (motor, housing) has cooled sufficiently and the air medium has mixed with cold air and cooled to below 60 °C. The fan should then only be approached close up and then only be touched if you are certain that it has cooled down. This applies in particular to high-temperature fans.
Overheating and damage to units resulting from stopping at temperatures >60 °C
In no circumstances should you stop the fan 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 fan increases while it is idle, the operator must wait for the temperature to fall to below 60 °C before restarting.
