General information regarding re-lubrication
Observe the following points regarding re-lubrication of the
bearings:
- Lubricate both bearings with the corresponding
quantity of grease with the fan switched on
- Use the lubricating grease specified on the information
plate on the fan and in accordance with specifications
in this operating manual
- Ensure that the boreholes provided for exuding of the
grease remain clear
- Remove the exuded lubricating grease
NOTICE!
Following re-lubrication, it is possible for the bearing
temperature to rise above the limit value for “pre-
alarm”. When the excess grease has been exuded,
the bearing temperature must return to normal
operating temperature within the range of
+55 … +80 °C.
NOTICE!
Ensure sufficient filling of the bearings, in particular
for ambient temperatures above +40 °C and with
utilisation of a bearing acoustic cover or other
housing.
Configuration with lubricating lines (optional):
With extracted lubrication points, approximately 20 grams of
lubricating grease can be calculated for each running meter
of lubricating line for filling of this lubricating line.
