Warning and safety instructions
~
Do not connect the appliance to the
mains electricity supply by a
multi-socket unit or an extension lead.
These do not guarantee the required
safety of the appliance (e.g. danger of
overheating).
~
This rangehood must not be
installed and operated in mobile
installations (e.g. on a ship).

Using at the same time as other
heating appliances that depend on
the air from the room
Warning - danger of toxic fumes
~
Great care should be taken when
using the rangehood at the same time
and in the same room or area of the
house as another heating appliance
which depends on the air in the room.
Such appliances include gas, oil, wood
or coal-fired boilers and heaters,
continuous flow or other water heaters,
gas cooktops, cookers or ovens which
draw air in from the room and duct
exhaust gases out through a chimney
or extraction ducting.
When used in extraction mode, with or
without an external motor fitted, the
appliance draws air in from the room in
which it is installed and from
neighbouring rooms.
If there is insufficient air, an
underpressure will occur. The heating
appliance may be starved of oxygen,
impairing combustion.
Harmful gases could be drawn out of
the chimney or extraction ducting back
into the room, with potentially fatal
consequences.
