Technical data
Commissioning (after replacement)
■
Remove any remaining installation material and foreign objects from the impeller and suction area.
■
Check direction of rotation (direction of rotation arrow on the impeller base disc).
■
During initial commissioning, the entire unit must be checked for mechanical vibrations. If necessary, re-balancing must be car-
ried out.
■
Pay attention to a quiet operation, without vibrations.
15. LIFETIME AND DISPOSAL
15.1. Product life
The motors are equipped with maintenance-free, permanently lubricated ball bearings. Under normal operating conditions, the ex-
pected lifetime is about 30,000 operating hours.
The information given here depends strongly on the respective field of application as well as the environmental conditions. We rec-
ommend replacing these fans after reaching about 30,000 operating hours or 5 years.
15.2. Decommissioning and disposal
When disassembling, parts under voltage are exposed, which can lead to electric shock when touched.
Before dismantling, disconnect the fan from all poles of the mains and secure against being switched on
again!
Parts and components of the device that have reached their lifetime, e.g. due to wear, corrosion, mechanical stress, fatigue and/
or all other, not directly recognizable effects, must be disposed of professionally and properly after disassembly in accordance with
national and international laws and regulations. The same applies to excipients in use such as oils and fats or other substances.
The conscious or unconscious reuse of used components such as e.g. impellers, rolling bearings, motors. etc. can lead to a risk to
persons, the environment as well as machinery and equipment. The applicable local operating regulations must be observed and
applied.
15.3. Spare parts (motor + impeller)
Only original spare parts may be used.
The repair may only be carried out by personnel trained and authorized.
