•
The electrical safety of this appliance can only be
guaranteed when continuity is complete between
the appliance and an effective earthing system
which complies with current local and national
safety regulations. It is most important that this
basic safety requirement is present and tested
regularly, and where there is any doubt, the
household wiring system should be inspected by a
qualified electrician. The manufacturer cannot be
held liable for the consequences of an inadequate
earthing system (e.g. electric shock).
•
For safety reasons, this appliance may only be used
when it has been fully installed.
•
Only open the housing as described in the
instructions. Under no circumstances should any
other parts of the housing be opened. Tampering
with electrical connections or components and
mechanical parts is highly dangerous to the user,
and can cause operational faults.
•
Installation, maintenance and repairs may only be
carried out by an authorised person in accordance
with current national and local safety regulations.
Repairs and other work by unqualified persons
could be dangerous. The manufacturer cannot be
held liable for unauthorised work.
•
Faulty components must only be replaced by
genuine original parts.
•
During installation, maintenance and repair work,
the appliance must be disconnected from the
mains electricity supply. It is only completely
isolated from the electricity supply when:
a) it is switched off at the isolator, or
b) the mains fuse is disconnected, or
c) it is switched off at the wall socket and the plug
withdrawn, or
d) the fuse to the fused spur connection unit is
withdrawn.
•
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 appliance may only be used
in mobile installations if a risk assessment of the
installation has been carried out by a suitably
qualified engineer.
•
In areas which may be subject to infestation
by cockroaches or other vermin, pay particular
attention to keeping the appliance and its
surroundings in a clean condition at all times.
Using at the same time as other heating
appliances that depend on the air from the same
room.
WARNING:
Danger of toxic fumes.
•
Great care should be taken when using the cooker
hood 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 hobs, 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, 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.
•
In order to ensure safe operation, and to prevent
gases given off by the heating appliances from
being drawn back into the room when the
cooker hood and the heater are in operation
simultaneously, an underpressure of 0.04 mbar (4
pa) is the maximum permissible in the room.
