5.1.3 Semi-automatic vacuum build up

(VE Semi Mode)

For semi-automatic vacuum build up, the start of the auto-
matic vacuum build up must be confi rmed with the extraction
cup button (fi g. 19).

Switch on the ATMOS S 351 Natal. Check that the indicator
lamp in the switch is illuminated.
The switch-on menu (fi g. 18, page 19) is shown on the
display for about 2 seconds.
The unit automatically goes to the VE Semi Mode (fi g.
20 and 21). The vacuum generated is displayed in this
menu (as fi gure and as bar graph). In addition, the va-
cuum build-up time (default = 120 s) is displayed at the
top left and the fi nal vacuum set at the top right (default =
-80 kPa). The ATMOS S 351 Natal attempts to generate
the -20kPa base vacuum.
