GB OPERATION
D&D
General Notes: the control system is touch-sensitive. To activate any function, it is only necessary to touch the
button lightly.
! button: this button will flash green when the hood is rising and will flash yellow when descending. If it shows
a red symbol when the on/off switch is on, this means the hood is in emergency shutdown mode (e.g. because
the grease filters are missing, or incorrectly installed). If this occurs during the descent phase, the hood will stop
and rise up a few centimetres. To allow the hood to operate correctly, reinsert or correctly reposition the grease
filters and press both the ! button and the on/off button at the same time.
ON/OFF button: when this button is used, the hood will rise up to its operating position. After a brief self-test
sequence, the motors will start. Pressing the button again will stop the motors and the hood will move back
to its shutdown position.

Speed control buttons: Pressing the „1,2,3,4,5,6,7,8,9" buttons sets the speed (power) of aspiration desired. The
speed can be selected directly, or by gradually changing through the possible speeds.
High Speed: tapping this control activates the „High Speed" aspiration level (10° speed). This will time-out after
approx. 8 minutes, after which the speed will return to level 9.
Grease filters saturated: when the motor is started, this indicator button will light for five seconds in a colour
that shows the level of filter saturation: Green 0-75%, Orange 76- 99%. If the indicator shows a constant red,
this means the metal grilles need to be washed (typically after 30 hours of use).
Carbon filters saturated: when the motor is started, this indicator button will light for five seconds in a colour
that shows the level of filter saturation: Green 0-75%, Orange 76-99%. If the indicator shows a constant red, this
means the carbon filters need to be washed or replaced (typically after 120hours of use).
RESET FILTERS
„Grease / Carbon filters saturated" when the indicator button shows red, pressing it will reset the indicator.
WARNING: This operation should be performed only after correct maintenance of the respective filter(s).Note:
to stop the motors and keep the mobile hood open— for example, to clean the hood—press both the ! button
andthe on/off button simultaneously.
CAUTION: If the hood is safety-locked (! button and on / off button lit in red) and the position of the carriage
does not allow to carry out the unlocking procedure, qualified personnel can raise or lower the carriage itself
by pressing together respectively the! button and saturation grease filters button (the carriage goes up at
progressive steps), or ! button and charcoal filter saturation button (the carriage goes down at progressive
steps). This procedure bypasses all security systems on the hood so it must be performed by a qualified
technician only.
