•
Fuses must always be only replaced; never repaired or bridged. The speci fi cations for
the maximum series fuse must always be adhered to (see Technical data). Only fuses
cited in the electrical circuit diagram may be used.
•
Keep the fan airways free. There is the danger of foreign bodies being sucked in and
objects
fl ying out!
•
Watch out for vibration free motion!
•
The impeller is subject to natural wear depending on the area of application and the
conveying medium. Regularly check that no deposits have formed on the impeller
which can lead to an imbalance and thus damage (see Chapter: Cleaning).
•
If highly aggressive media for which the product is not suited are conveyed, the
severe corrosion may result in the impeller breaking. Any impellers corroded in this
way must be replaced immediately.
•
Deposits on the motor, particularly on the cooling fi ns and in recesses on the stator –
can lead to reduced cooling and the motor switching off prematurely. For this reason,
remove deposits in good time (see Chapter: Cleaning).
•
Maintenance interval in accordance with the degree of contamination of the impeller!
•
Check the fan at regular intervals (recommendation: every 6 months) for mechanical
oscillations. Observe the limits speci
fi ed in ISO 14694 and, if they are exceeded,
implement remedial measures (e.g. rebalancing by specialist staff).
•
Check the impeller, in particular the weld-seams, for possible cracks.
•
Repair, e.g. by welding is prohibited!
•
Bolted-on wheels and/or wings may only be replaced by authorised ZIEHL-ABEGG SE
staff. The manufacturer shall not be liable for damage caused through improper repair
work.
•
When opening cable glands on the fan / motor, check the condition of the threaded
connections and seals. Always replace defective or brittle threaded connections and
seals.
•
Regularly check the earth connection of all components.
