5. Grease filter alarm reset key

After 

80 hours

of operation, the ON key comes on to indicate that the grease filter needs cleaning.

Once the grease filter has been cleaned press "

5

" for at least 3 seconds while the hood is ON, and operating at any speed.

6. "6th Sense" key /"Air Quality Control" (Automatic Operation) 
IMPORTANT: this function does not activate if the hood is OFF.

With 

Automatic operation

the hood can operate in two different modes. To set either mode keep pressing key "

6

" until the desired mode is activated. The

"

6th Sense

" mode (key "

6

" comes on), ensures correct suction of cooking steams based on the environmental conditions detected.

During cooking the system promptly reacts to any Steam/Gas increase, and remains at the set speed for at least 1 minute before returning to the lower speed or
switching off.
At the end of cooking, when the environmental conditions have returned to those before cooking, the system switches off: However, if the conditions are similar
to the stand-by parameters, the hood will be switched off 30 minutes after, even if the stand-by parameters have not actually been reached.
The "

Air Quality Control

" mode ("

LD5

" comes on) uses the hood as an air monitoring system, ensuring a high air quality level.

The system promptly reacts to any Steam/Gas increase, and remains at the set speed for at least 1 minute before returning to the lower speed, or switching off.
After the effect of the gas is terminated, when the environmental conditions have returned to those before cooking, the system switches off:

Note: 

Each time the hood goes from OFF to Stand-by mode, the system enters "

6th Sense

" mode.

To exit 

Automatic Operation

press keys "

2

" or "

3

" (the "

LD5

" led or the "

6

" key go off), decreasing or increasing the automatic speed by one step, or press "

1

"

to return to 

Stand-By

mode.

7. Carbon filter alarm reset key 

After 

320 hours

of operation, with the hood ON, the carbon filter alarm reset key comes on to indicate that the carbon filter needs cleaning.

Once the carbon filter has been cleaned press "

7

" for at least 3 seconds while the hood is ON, operating at any speed, to reset the filter alarm.

In standard mode, the electronic system is set to provide notifications for the grease filter only.
To activate notifications for the carbon filter, place the hood in 

Stand-by

and then press keys "

5

" and "

7

" for 3 seconds.

Activation is confirmed by keys "

5

" and "

7

" flashing for 3 seconds.

Repeat the operation to deactivate carbon filter notifications. Key "

5

" will flash for 3 seconds.

Each time the status is changed, an extended "beep" is heard.

Automatic sensor calibration

The system requires automatic sensor calibration. This calibration is performed, with the motor off, during first installation, as well as each time power supply is
cut off.
This operation is confirmed by key "

6

" flashing and key "

1

" coming on.

Manual sensor calibration

The system can also be manually forced to perform the calibration procedure as follows:
Place the hood in Stand-by and press "

6

" for 5 seconds.

This operation is confirmed by key "

6

" flashing and key "

1

" coming on.

This operation should be performed when:
•

the hood is installed for the first time;

•

there is a power cut lasting several hours or days;

•

a very quick temperature change occurs in the kitchen.

Sensor test

The sensor test is performed continually during automatic operation.
In case of fault, keys "

1

" and "

6

" flash (contact customer service). In this case it will still be possible to use the hood in manual mode.

Note:

to optimise sensor performance:

•

always keep the sensor area clean and free from any obstructions that may prevent air from reaching the sensor element;

•

ensure that no water (or other liquid) sprays reach the sensor;

•

avoid contact of the sensor with organic solvents, silicon resins and ammonia.
