5.1 Cleaning
To ensure a long service life, check the fans regularly for proper
operation and soiling. The frequency of checking is to be adapted
accordingly depending on the degree of soiling.
DANGER
Risk of injury from rotating fan.
→ Only clean when not in motion. Interrupt the power supply,
secure against renewed switch-on. Secure against start-up,
prevent air flow.
;
Dirt deposits on the motor housing can cause overheating of the motor.
;
Soiling of the impeller can cause vibration that will shorten the service
life of the fan.
;
Severe vibration can destroy the fan.
;
In such cases, switch off the fan immediately and clean it.
;
The preferred method of cleaning is dry cleaning, e.g. using
compressed air.
;
If water is required for cleaning, the preferred method is to perform
cleaning with a conventional water hose or to employ foam cleaning.
;
Do not use aggressive 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
;
If cleaning agents have been used, rinse these off with clean water.
;
If severe corrosion is visible on load-bearing or rotating parts, switch
off the device immediately and replace it.
;
Repair of load-bearing or rotating parts is not permitted.
;
Operate the fan for 2 hours at maximum speed to permit the
evaporation of any water that has ingressed.
;
If cleaning does not eliminate vibrations, the fan may need to be
rebalanced. To have it rebalanced, contact ebm-papst.
;
The fan is equipped with maintenance-free ball bearings. The lifetime
lubrication of the ball bearings is designed for a service life of 40,000
hours.
;
If bearing replacement is necessary after that period, contact ebm-
papst.
;
Adapt the maintenance intervals to the level of dust exposure.
