These instructions contain important information on how to operate the ATMOS S 351 Natal safely, properly and effi ciently. It should, therefore, not only be used for new operators who have to be instructed, but also as an ongoing source of reference.
The ATMOS S 351 Natal is a mains-operated suction unit. The quiet, maintenance-free diaphragm pump forms the core of the ATMOS S 351 Natal. It creates a vacuum in the collection jar which assists in drawing off and collecting the secretions.

5.0 Operation Electronic fi lling level monitoring The ATMOS S 351 Natal is equipped with an electronic fi lling level monitoring which, in VE mode, does not affect the per- formance of the pump. The vacuum is not decreased. The alarm signal for a full jar (fi...
5.1.2 Fully automatic vacuum build up (VE Auto Mode) Switch on the ATMOS S 351 Natal. Make sure that the pilot lamp in the switch lights up. Then, the switching-on menu (fi g. 15) is shown in the display for approx. 2seconds.
Page 19
In addition, the desired vacuum build up time (default = 120 s) is shown top left and the fi nal vacuum set at the top right (default = -80 kpa). The ATMOS S 351 Natal attempts to build up the base vacuum of -20kPa. ...
(fi g. 19). Switch on the ATMOS S 351 Natal. Check that the indicator lamp in the switch is illuminated. Fig. 19. Extraction cup button The switch-on menu (fi g. 18, page 19) is shown on the display for about 2 seconds.
Page 21
5.0 Operation After the -20 kPa base vacuum has been reached, the unit waits for the extraction cup button to be depressed. During this waiting period, an alert tone sounds syn-chronised with the fl ashing of the green LED. When the extraction cup button is pressed, the alert tone stops and the automatic vacuum build up starts (fi...
5.0 Operation 5.1.4 Controlled venting (vacuum release) After completed vacuum extraction or at any other time in VE Mode (VE Auto Mode and VE Semi Mode), the extraction cup can be vented in a controlled manner over a preset period (default: 5 s) (fi g. 25 and 26) by pressing the END button (fi...
5.0 Operation 5.1.5 Additional functions In the VE mode of the ATMOS S 351 Natal it is possible at any time to intervene in the operation of the unit using the arrow buttons (fi g. 28). The Max button is locked.
During VE mode, it is possible to transfer the control of the vacuum to the connected foot regulator. The ATMOS S 351 Natal automatically goes into Suction mode in this case. The ATMOS S 351 Natal must be switched off before the foot regulator is connected or disconnected. ...

5.0 Operation Presetting the vacuum with the foot regulator The ATMOS S 351 Natal must be switched off before the foot regulator is connected or disconnected. Completely depress the connected foot regulator to the heel position. Switch on the ATMOS S 351 Natal. Check that the lamp in the switch is illuminated.
The warning signal is cleared as soon as vacuum build up can be continued or after abortion of the action by the user. The ATMOS S 351 Natal cannot predict a loss of contact of the extraction cup. There is no warning for this.
The vacuum currently present is not affected (there is no vacuum release). To avoid malfunctions, use the supports on the unit for original ATMOS jars only. 5.2.6 Electronic fi lter monitoring Fig. 32. Warning of short circuit between contact See page 17.

If this happens, the overheating display Fig. 46. Overheating is left on the graphics display. Please call the service depart- ment if this happens. Set up the ATMOS S 351 Natal on a clear, level surface. This will ensure free air circulation. 5.6.3 Fault If the ATMOS S 351 Natal detects a functional fault, this will be shown on the graphics display.
6.0 Cleaning and Maintenance Reprocessing of hoses and collection jar Always wear protective clothing (gloves) when carrying out cleaning work. Those parts which come into contact with the secretion must be cleaned and disinfected after each use before a new patient is treated.
