Aspiration speed adjustment
The fan’s speed is visualized on the display. In order to change it, use the increase/decrease keys positioned
over the MENU key.
Fan self-switching off
The programmable time MAX TIME can change between 0 (DISABLED, default value) and 24 hours. In order to
visualize alternately set time and elapsed time, press SET/MUTE key.
ELAPSED TIME is automatically updated by the software. Normally, it is automatically zeroed after the fan’s self-
switching off, but it can be zeroed by the operator by pressing at the same time the increase/decrease keys placed
over MENU key.
The count happens only if the fan is in operation.
Filter life
Visualizes/sets the life of the filter in order to effect the relative replacement.
The programmable time MAX TIME can change between 0 (DISABLED) and 999 hours. The default preset time is
equal to 600 hours.
In order to visualize alternately set time and elapsed time (updated automatically by the software), press SET/MUTE
key.
When elapsed time reaches the maximum value MAX TIME, a visual and acoustic alarm enters into action to advise
the operator to change the filter because it is saturated.
In order to silence the acoustic alarm press SET/MUTE key. The red LED, instead, disappears only after zeroing
ELAPSED TIME (effect this operation only after changing the filter, in compliance with the safety regulations).
