1. Operational safety
All safety instructions included in this manual shall be observed without exception!
Grease filters and active carbon filters should be cleaned and replaced according to manufacturer's
instructions, or more frequently in periods of intensive use (more than 4 hours a day).
If a gas cooker is used it is forbidden to leave uncovered flame. When removing pots from gas burners set the
flame to its minimum level.
Always make sure that flame does not extend outside the pot. Such a situation causes undesired energy losses
and dangerous heat build-ups.
The hood should not be used for other purposes than those for which it was designed.
2. Operation
2.1 Control panel
Operation of the hood can be controlled by means of a combined switch:
- „0/1" – hood on / off, green diode.
- „2" – second motor speed, orange diode.
- „3" – third motor speed, red diode.
- „T" – switch-off timer – TIMER- switches the hood off after 15 minutes, the diode
pulsating.
- „L" – lighting on / off.
2.2. Program function
Timer function: IDT 9440 E and IDT 12440 E kitchen extractor hood is equipped with the
option of programming automatic switch-off of the hood fan. „Timer" is actuated by
pressing „T" button (Fig. 5) during operation of the hood with the required fan speed.
The motor will be switched off after 15 minutes.
NOTE:
The microprocessor system may get deleted or crash during momentary voltage
drops in the network, and stop responding to commands from the keyboard. In
such case the hood has to be disconnected from and then connected again to the
power network in order to reset the system.
