Final Vacuum Is Not Reached; Suction; Electronic Fill-Level Monitoring System - Atmos S 351 NATAL Operating Instructions Manual

 The ATMOS S 351 NATAL cannot predict that the extraction cup will tear off. There is
no warning for this.

4.8.4 Final vacuum is not reached

• If the time for vacuum build-up has elapsed and the final vacuum has not been
achieved, the device will wait for about another 35 s and then issue a warning sig-
nal: fast flashing of a red LED and a beeping sound synchronised with the blinking
LED.
• The warning signal indicates a leak in the system which prevents the final vacuum
from being achieved.
• The warning signal stops as soon as the final vacuum is reached again or after the
user cancels the action.

4.10 Electronic fill-level monitoring system

The ATMOS S 351 NATAL has an electronic fill-level monitoring system that switches off
the pump when the maximum fill level is reached. At the same time, the device beeps
and then Secretion canister full appears in the display. The maximum fill level is reached
when the liquid comes into contact with the sensor in the secretion canister lid. If a large
amount of foam is generated, you should fit the enclosed anti-foaming device over the
sensor so that the unit does not switch off prematurely. As soon as the sensor is no
longer in contact with the liquid (e.g. on replacing the double hose connector), the pump
switches on again.
2. Press the + (6), – (5) or MAX (7) buttons to set the
target vacuum.
» The target vacuum at the bottom of the display and
the black line in the right bar change.
» The current vacuum in the middle of the display and
the blue bar change.
 Keeping the – (5) or + (6) button pressed changes the
vacuum value faster.
When the target vacuum has been reached, the indicator
for the current vacuum in the display changes from blue
to green.
