Causes for damages
9 CAUTION
Risk of damage due to corrosion. Always turn
appliance on when cooking to avoid condensation
buildup. Condensation can lead to corrosion
damages.
Always replace defective bulbs immediately to avoid an
overload of the remaining bulbs.
Risk of damage due to ingress of humidity into the
electronic circuitry. Never clean operator controls with a
wet cloth.
Surface damage due to incorrect cleaning. Clean
stainless steel surfaces in the grind direction only. Do not
use any stainless steel cleaners for operator controls.
Surface damage due to strong or abrasive cleaning
agents. Never use strong and abrasive cleaning agents.
Risk of damage from condensation back flow. Install
exhaust vent at a slight downward slope away from the
appliance (1° slope).
Protecting the environment
Unpack the appliance and dispose of the packaging in
line with environmental requirements.
General notes
Exhaust air mode
Note: Ventilation may not exit through an already
operational smoke or exhaust chimney, nor a duct used
for ventilating furnace installation areas.
▯
If the ventilation is intended to pass through a smoke
or exhaust that is not in operation, the responsible
area heating inspector must give approval.
▯
If the ventilation passes through an external wall, use a
telescope wall sleeve.
Ventilation line
Note: The manufacturer does not assume any warranty
for complaints attributable to the pipe section.
▯
The device achieves its optimum performance by
means of a short, straight exhaust air pipe and as
large a pipe diameter as possible.
▯
The optimum extraction performance is not achieved
and fan noise is increased if exhaust air pipes are long
and rough and if there is a large number of pipe bends
or diameters less than 5 15 /
16
” (150 mm).
▯
The pipes or hoses for laying the exhaust air line must
consist of non-combustible material.
Round pipes
An inner diameter of 5
15 /
16
” (150 mm), but at least 4 3 /
4
”
(120 mm), is recommended.
Flat ducts
The inner cross-section must correspond to the diameter
of the round pipes.
Ø 5

” (120 mm) approx. 17 ½ sq in (113 cm 2 )
▯
Flat ducts should have no sharp deflections.
