5�4 Filter Cleaning; 5�6 Deactivating The Automatic Start In The Automatic Operation Mode - Renfert SILENT compact Mode D'emploi

5.4 Filter Cleaning
In order to guarantee maximum suction performance, the unit is equipped with an automatic cleaning
function for the filter unit. The cleaning function takes approx. 8 sec.
en
The cleaning process is carried out:
• When the unit is switched on;
• Before the dust drawer is removed, when the cleaning function is activated (see chapter 6�2 Empty dust
drawer);
• When the unit has been in operation (turbine running time) for more than 16 hrs without having been
switched off in between�
After an automatic filter cleaning, in case of a renewed drop of the flow velocity, the next filter
cleaning will be performed only after 2 hours of turbine running time.
5.5 Automatic Switch-on for Automatic Operation
The switch-on threshold, which activates and deactivates the suction
function when a connected electrical device is operated, can be set�

♦ The display for automatic operation (20) blinks�

should function and let it run for 3 - 5 seconds (to allow for over currents which occur when the device is
initially switched on)�
⇒ Press the enter key (25) (whilst the handpiece is still in use)�
♦ The display for automatic operation (20) and continuous operation (22) light up at the same time for
approx� 2 seconds�

Devices with a stand-by mode should be switched on approx. 5 minutes before setting, in order to
prevent measurement errors.

up and an acoustic signal is emitted three times.Press Enter key (25) and restart the setting.
5.6 Deactivating the automatic start in the automatic operation mode
