Note
Prevent air from being drawn in through the condensate
drain.
f Install the condensate drain hose in such a way as to
create a siphon with a water trap height of at least
60mm.
f Before connecting the condensate drain hose to the appli-
ance, pour water into the siphon.
f Push a condensate drain hose onto the condensate drain
connection.
f Prevent the condensate drain hose from slipping off the con-
densate drain connection, e.g. with a cable tie.
10.2.1 Optional : Condensate pump
Standard delivery
- Pump assembly : The pump assembly consists of a pump
module and a float module that are already connected elec-
trically and to a condensate hose in their delivered condition.
- Vent hose
- Hose bend for the connection between appliance and float
module.
- 3 cable ties
Installation
f Flush the condensate pan with water so that no impurities
(e.g. metal swarf or EPS beads) block the condensate pump.

f Hook the condensate pump assembly onto the hooks provid-
ed on the long side of the appliance.

f Push the supplied hose bend onto the appliance condensate
drain connection. Secure the hose bend with a cable tie.
f Push the other end of the hose bend onto the connection on
the float module. Secure the hose bend with a cable tie.
f Connect the supplied vent hose to the float module. The con-
nection on the float module is above the condensate outlet.
f Undo the cable tie that has sealed the vent hose which comes
out of the appliance.
f Push the vent hoses into one another.

f Connect a condensate hose to the condensate outlet of the
condensate pump and route it into a drain. In order for the
condensate pump not to run dry, the condensate hose behind
the pump must not route directly downwards.
f Connect the power supply of the condensate pump.

10.3 Air ducts
!
Material losses
Never link cooker hoods to the ventilation system.
!
Material losses
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.
10.3.1 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.
