Translation of the original operating instructions
Fig. 5: Cleaning of the fan with a high-pressure cleaner.
;
Maximum water pressure 80 bar
;
Minimum clearance between water outlet and fan 40 cm
;
The water jet must be aimed perpendicularly to the blades.
;
If possible, only aim the water jet at the rotating parts.
;
Do not aim the water jet directly at the condensation drainage hole (if
applicable).
;
When cleaning the electronics housing, do not aim the water jet
directly at the terminal box cover or cable glands.
;
If there is a condensation drainage hole in the rotor, make sure this is
not blocked by dirt.
;
Completely remove any cleaning agents used.
;
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 so that any water that
has ingressed can evaporate.
;
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 actual 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.
