Motor problems
• Is there a power supply failure?
• Is the plug properly inserted in the
socket?
• Is the fuse blown?
The hood capacity is insufficient
/ operating noise has increased:
• Is the size of the exhaust air pipeline
s
uff
icient?
• Is the exhaust air duct blocked?
• The cross section of the air pipeline
(from the hood to the wall box incl.)
should be 150 mm wide.
• A smaller air pipeline cross-section
can possibly impair the motor power.
• The ai
r fl
ow can be obstructed if the
wall box i
s fi
tted wit
h a fl
y screen.
• If this is the case remove th
e fl
y
screen.
• If the cover plate of the wall box
ha
s fi
xed, very inclined louvres, you
should remove the plate to check
whether this solves the problem.
• Mount a cover plate with movable lou-
vres in the wall box, as this will least
obstruct the ai
r fl
ow.
• Is / are th
e fi
lter(s) clean?
• Was / were the carbo
n fi
lter(s)
installed more than six months ago?
Then this/these should be changed.
• Is the air taken from the kitchen being
replaced by su
ff
icient fresh air, so that
no partial vacuum is being produced
in the room?
When the lightning fails:
• Does the lamp need changing?
• Has the lamp been properl
y fi
tted and
seated in the holder up to the stop?
• Is the fuse blown or has the circuit
breaker tripped out?
