7.2 Plastic hose is twisting
Fault description:
¾ The swivel arm can no longer be extended. (mechanically
blocked)
Cause of fault:
¾
The plastic hose has become so twisted that the swivel arm
is blocked.
Troubleshooting:
¾ Remove the appliance, loosen the pipe clip and fit plastic hose
without twisting it.
7.3 Too little air power
Complaint:
¾ Extraction is too weak or the fumes go past the extraction arm.
Cause:
¾ Units VL 051 and GB 031 have a free-blowing air power
of 350 m³/h. (See performance characteristic)
Additional pipelines reduce the power further. Flat ducts are
unsatisfactory as regards air flow and should not be used.
¾ The intake area of the swivel arm is very small in comparison
with a hood. Depending on the position of the hob, not all fumes
are detected.
Rectification:
¾ Check direction of rotation of the fan.
Viewing the intake connection
from above, the fan impeller must
rotate in a clockwise direction.
¾ Check pipe installation. If pipelines are long or flat ducting is
used, the air power is reduced considerably.
