General ventilation
connections
• Ventilation installation must be carried out in accord-
ance with current norms and directives.
• Connections must be made via flexible hoses, which
should be installed so that they are easy to replace.
• Provision must be made for inspection and cleaning
of the duct.
• Make sure that there are no reductions of cross-sec-
tional area in the form of creases, tight bends, etc.,
since this will reduce the ventilation capacity.
• The air duct system must be a minimum of air tight-
ness class B.
• To prevent fan noise being transferred to the ventila-
tion devices, silencers should be installed in the duct
system. In the event of ventilation devices in noise-
sensitive rooms, silencers must be installed.
• Ducts that may become cold must be insulated with
diffusion-proof material (at least PE30 or equivalent)
along their entire length.
• Ensure that the condensation insulation is fully sealed
at any joints and/or at lead-in nipples, silencers, roof
cowls or similar.
• A duct in a masonry chimney stack must not be used
for extract air.
• The exhaust air module must be provided with the
enclosed air filter.
EXHAUST AIR DUCT /KITCHEN FAN
Exhaust air duct (kitchen fan) must not be connected to
S135.
To prevent food vapour being transferred to S135 the
distance between the kitchen fan and the exhaust air
device must be considered. The distance should not be
less than 1.5 m, but this can vary between different in-
stallations.
Always use a kitchen fan when cooking.
INSTALL THE FILTER CARTRIDGE
The filter cartridge has two sizes of connector, 125 mm
or 160 mm.
1. Check the diameter of the air channel for inlet air.
2. When the air duct has a large diameter (Ø 160 mm)
the inner ring must be cut out of the upper section
of the filter cartridge.
3. Cut just inside the inner edge of the outer ring using
a sharp knife. The plastic is prepared for easy cut-
ting.
4.
Press the filter cartridge into place in the connection
for incoming air (XL43).

INSTALL THE CONNECTOR
If a filter solution other than that enclosed is used, the
enclosed coupling must instead be mounted in the
connection for incoming air (XL43).
INSTALL THE SILENCER
1. Remove the plugs from the silencer enclosed.
2. Install the silencer in the connector for outgoing air
(XL44).
