Grease trap Signal
After 40 hours of operation the led L5 turns on.
When such signal appears the installed grease trap needs to
be washed.
To reset the signal hold down key 1 for 3”.
Carbon filter Signal
After 160 hours of operation the led L5 flashes.
When such signal appears the installed carbon filter must be
substituted.
To reset the signal hold down key 1 for 3”.
In the case of both filters signalling at the same time, the led
L5 will indicate the alarms alternately remaining on for 3" and
subsequently flashing 3 times.
The reset takes place by carrying out the procedure described
above 2 times.
The first time resets the grease trap signal, the second resets
the carbon filter signal.
In the standard mode the carbon filter signal is not active.
In case one uses the hood in filter version is it necessary to
enable the carbon filter signal.
Carbon filter signal activation:
Position the hood in OFF and simultaneously hold down keys
1 and 4 for 3”.
The led L1 and L2 will flash for 5”.
Carbon filter signal deactivation:
Position the hood in OFF and simultaneously hold down keys
1 and 4 for 3”.
The led L1 will flash for 2”.
Temperature Alarm
The hood is equipped with a temperature sensor that activates
the motor to speed 3 in the case that the temperature in the
control zone becomes too elevated.
The alarm condition is indicated with the sequential flash of
the leds L1, L2, L3.
This condition remains until the temperature falls below the
alarm threshold.
You can get out of this mode by pressing key 1 or 2.
Every 30” the sensor checks the environmental temperature of
the display zone.
