6.1 Cleaning
NOTE
Damage to the device during cleaning
Malfunction possible
→ Do not clean the device using a high-pressure cleaner.
→ Do not use acid, alkali or solvent-based cleaning agents.
→ Do not use any pointed or sharp-edged objects for cleaning
Instructions for cleaning
●
Check the unit regularly, with particular attention to smooth operation
and dust buildup on the impeller and motor housing.
●
Heavy dust buildup, especially on the motor housing and the
impeller, and/or strong vibrations, can destroy the fan. In this case,
switch off the fan immediately and clean it.
●
If heavy corrosion is identified on load-bearing or rotating parts of the
unit, switch it off without delay and replace it. Repair of load-bearing or
rotating parts is not permitted.
●
Only clean the unit when it is stopped; disconnect it from the power
supply and secure it against restarting.
●
Do not use aggressive cleaning agents!
●
Only direct water jets at the rotor side, never at the motor side.
●
Avoid directing the water jet at the condensation drainage hole.
Maximum water pressure: 80 bar
●
After cleaning, run the fan for at least an hour at maximum speed.
●
Make sure that the condensation drainage hole (if present) is not
obstructed by dirt.
●
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.
●
Adjust maintenance intervals to the level of dust exposure.
6.2 Safety inspection
NOTE
High-voltage test
The integrated EMC filter has Y capacitors. The tripping current
is exceeded when AC testing voltage is applied.
→ Test the device with DC voltage when you perform the
legally required high-voltage test. The voltage to be used
corresponds to the peak value of the AC voltage required by
the standard.
