Warning and Safety instructions
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 "Corgi" installer, 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 "Corgi" installer, must be sought.
If the hood is being operated in recirculation mode, the above restrictions do not apply.
