Filter checking device for the detection of
grease and active carbon
This type of vapour hood is predisposed with a device that signals when
the grease or active carbon filter requires cleaning (sold with the active
carbon filter by the manufacturer specialized in ventilation equipment).
This type of vapour hood is supplied by the manufacturer without the
active carbon filter, therefore the saturation signal is disabled.
The hood is purchased with active carbon filter included, and the
saturation signal is activated as follows:
Depress and hold the A and B buttons simultaneously for 3 seconds.
Initially only the LED indicator signal for the grease filter C is activated,
shortly after the LED indicator for the active carbon filter D will activate,
at this point the saturation detection has been enabled.
To switch off the saturation detection : depress and hold the A and B
buttons for 3 seconds until the LED indicator for the active carbon filter
is flashing.
Led – Indicator for grease filter C
The LED indicator for the grease filter will flash when it requires
cleaning.
Follow the maintenance instructions.
Led - indicator for active carbon filter D
The LED indicator for the active carbon filter illuminates when the filter
requires replacing.
This occurs after about 160 working hours from when the active carbon
filter was first put into operation.
Resetting the saturation indicator
After cleaning the filter depress and hold the G and H buttons again for
3 seconds until the LED – grease filter indicator or the LED – active
carbon indicator D are no longer flashing.
