4Maintenance Instructions
4.1 DA 600 Wall Exhaustion
Normally, the wall exhaustion does not require any maintenance apart from cleaning.
4.2 Guard Net
•Clean them if they show signs of blocking. Only a few mm of dust result in a major increase
of energy consumption.
4.3 Fan
Service and cleaning of the fan are not to be carried out, until the electricity has been
properly switched off.
•Motor and electric installations have been carried out according to the protection class IP54. This
means that high-pressure cleaning against packing surfaces, bearings, etc. is not to take place.
•Clean the fan at regular intervals so the cooling and air can pass unimpededly.
•If dismantling of the fan is required for regular cleaning, it is recommendable to have a long
rubber cable installed, which can be drawn down with the fan. This way, electrical
disassembling can be avoided. An alternative could be to mount an ISO approved connector.
•If service requires dismantling of the fan and there is no long cable connected, the area
around the plug on the motor must be cleaned thoroughly before dismantling the motor.
Subsequently, covering is necessary to ensure that no dirt enters the motor and plug, which
may cause operational problems.
•Check at least once a year if bearings, gaskets, etc. are intact.
•The fan is not to be stopped by placing hard objects between the fan blades, as they will
then be damaged.
•The fan is not to be weighted with more than its own weight.
5Trouble Shooting Instructions
5.1 DA 74
See Trouble Shooting Instructions in the DA 74 winch motor instruction (603701).
5.2 Fan
•If the fan has difficulties in running or shows signs of irregular operation it may be caused
by a defective capacitor. Contact authorized personnel for replacement.
•If a rumbling sound comes from the bearings or the motor gets relatively warm around the
bearings, it may be due to defective bearings. Replacement of bearings should only be done
by authorized personnel.
