grille or internal shutter
via locking hooks.
Check impeller and
clean if necessary.
Fan does not switch
off.
• Overrun time (max. 25
min.). Wait for overrun
time and reduce if ne-
cessary.

Fan does not switch
off or fan switches on
when not wanted.
• A high-impedance
voltage is present at
terminal L1 due to a
glow lamp in the con-
trol switch, cables laid

transformers or other
electrical components.

X2 capacitor (220 nF/
250 V) to zero.
