•
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.
•
The fan or motor is maintenance-free due to the use of ball bearings with “ life-time lubrication ” . At
the end of the grease service life ( Technical Data), it is necessary to change the bearing. The
grease service life may be lower than the theoretical value stated there (F
10h
) if particular operating
conditions such as vibrations, humidity or soiling in the bearing, unfavourable control modes, etc.
are present. Please consult our Service Department with regard to changing the bearing as for all
other damage (e.g. to the coil or electronics).
•
Regular inspection and possibly cleaning is necessary to prevent imbalance and blockage of the
condensation bores due to ingress of dirt.
•
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.
Information
Con fi rmation number for inquiries or in service cases rating plate.
State the additionally engraved con fi rmation number (available depending on the motor build) if the
rating plate is no longer legible. This can be found under the af fi xed rating plate or on the stator fl ange
(in external rotor motors) depending on the motor size.
8.2 Cleaning
Danger due to electric current
Voltage supply for motor must be interrupted and secured against restoration!
Clean the fans`s
fl
ow area.
Attention!
•
Do not use any aggressive, paint solvent cleaning agents when cleaning.
•
Make sure that no water gets inside the motor and the electronics (e.g. by direct contact with seals
or motor openings), observe protection class (IP).
•
In case of improper cleaning work, no warranty is assumed regarding corrosion formation / paint
adhesion for unpainted / painted fans.
•
To avoid accumulation of moisture in the motor, the fan must be operated for at least 1 hour at 80%
to 100 % of the maximum speed before the cleaning process!
•
After the cleaning process, the fan must be operated for at least 2 hours at 80 to 100 % of the
maximum speed for drying purposes!
