10.3 Connecting the condensate drain hose

Material losses
!
To ensure that condensate drains correctly, always lay
the condensate drain hose without any kinks. Lay the
condensate drain hose with a fall of at least 10 %. The
appliance must be installed horizontally.
The drain pipe may only contain one siphon. The con-
densate must be able to drain freely downstream of the
siphon. The condensate must drain away via the domestic
sewer system. The pipes must not rise in the domestic
sewer system downstream of the siphon. The condensate
drain must be free from the risk of frost.

!
A float switch prevents condensate from reaching live
parts in the unit.
If the condensate drain hose is installed incorrectly, the
float switch cannot prevent the uncontrolled leakage of
condensate.
Note
To ensure the unit is airtight, there may be no inter-
ruption in the condensate drain between the unit and
the trap. Use the supplied condensate drain hose and
mounting bend.
The standard delivery includes a condensate drain hose and a
hose clip. Connect the thinner end of the condensate drain hose
to the appliance.
f Use the mounting bend included in the standard delivery to
install the condensate drain hose in such a way as to create a
siphon with a water trap height of at least 80 mm.
f Before connecting the condensate drain hose to the appli-
ance, pour water into the siphon.

1 Hose clip
f Slide the hose clip onto the condensate drain hose far
enough to be able to push the hose onto the condensate
drain connector without squeezing the hose clip.
f Push the condensate drain hose onto the condensate drain
connector.
f Push the hose clip towards the appliance so that it secures
the hose on the condensate drain connector.

10.4 Air ducts

Material losses
!
Never link cooker hoods to the ventilation system.

!
During installation, ensure that no metal swarf enters
the pipework. However, should this occur, remove this
debris, otherwise the fans may be damaged.
Install the air ducts using materials that can be obtained from us
or with commercially available folded spiral-seam tubes.
10.4.1 Insulation against condensation
Material losses
!
When warm air meets cold surfaces, condensation can
result.
f For outdoor air and exhaust air ducts, use vapour
proof thermally insulated pipes.
f If the supply and extract air ducts are routed
through unheated rooms, insulate these ducts as
well.
