Miele DA 428-4, Operating And Installation Instructions

Page: 8 / 40

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 in the
room of 0.04 mbar (4 pa) is the
maximum permissible.
Ventilation can be maintained by air
inlets which cannot be blocked, in
windows, doors and outside wall vents,
or by other technical measures, such
as ensuring that the cooker hood can
only be switched on when the heating
appliance is switched off or vice versa.
A ventilation brick alone is not generally
sufficient to ensure safe ventilation.
,
The overall ventilation condition
of the dwelling must be taken into
account. If in any doubt, the advice
of a competent builder or, for gas, a
qualified gas fitter (registered with
an official gas safety body in
accordance with national safety
regulations, GasSafe in the UK),
must be sought.
One of the following technical
measures may be necessary to ensure
safe operation.
– If the only way of ensuring adequate
ventilation is via an open window, a
window contact switch should be
fitted to ensure that the cooker hood
can only operate when the window is
opened sufficiently. A window
contact switch kit is available from
good builders' merchants.
Take care when ventilating the room
through an open window that
ventilation is not impaired by a
closed blind or curtain.
– The cooker hood can be set up to
automatically switch on an air intake
fan or open a motorised inlet flap
when it is switched on.
– The cooker hood can be set up to
automatically switch off a heating
appliance which also depends on
the air from the room when it is
switched on.
The Miele DSM 400 control module
offers the possibility of combining other
components with the cooker hood (see
"Operation with Control module DSM
400"). It is available to purchase as an
optional extra.
If in any doubt, the advice of a
competent builder or, for gas, a
qualified gas fitter (GasSafe
registered in the UK) must be
sought.
If the hood is being operated in
recirculation mode, the above
restrictions do not apply.
