6.1 Cleaning
To ensure a long service life, the fans have to be regularly checked for
proper operation and degree of soiling. The frequency of the checks is to
be adapted to the occurrence of soiling.
DANGER
Risk of injury from rotating fan.
→ Only clean when not in motion. Do not disconnect the fan
from the power supply, just switch it off via the control input.
This will prevent start-up of the fan.
;
Dirt deposits on the motor housing could lead to overheating of the
motor.
;
Dirt on the impeller can cause vibration which would shorten the
service life of the fan.
;
Severe vibration could destroy the fan.
;
In such cases immediately switch off and clean the fan.
;
The preferred method of cleaning is dry cleaning, e.g. using
compressed air.
;
Use is never to be made of corrosive cleaning agents!
NOTE
Damage to the device during cleaning
Malfunction possible
→ Do not clean the device using a water jet or high-pressure
cleaner.
→ Do not use any acid, alkali or solvent-basedcleaning
agents.
→ Do not use any pointed or sharp-edged objects for cleaning
;
Completely remove any cleaning agents used.
;
Immediately switch off and replace the device if severe corrosion is
apparent at load-bearing or rotating parts.
;
Repairs to load-bearing or rotating parts are not permissible!
;
Operate the fan for 2 hours at maximum speed to permit the
evaporation of any water which may have ingressed.
;
If cleaning does not eliminate vibration, the fan may have to be re-
balanced. In such cases please contact ebm-papst.
;
The fan is provided with maintenance-free ball bearings. The lifetime
lubrication of the ball bearings is designed for a service life of 40,000
hours.
;
Please contact ebm-papst if bearing replacement is required after this
period.
;
Adapt the maintenance intervals to the dust pollution occurring.
6.2 Safety test
NOTE
High-voltage test
The integrated EMC filter contains Y capacitors. Therefore, the
trigger current is exceeded when AC testing voltage is applied.
→ Test the device with DC voltage when you carry out the
high-voltage test required by law. The voltage to be used
corresponds to the peak value of the AC voltage required by
the standard.
