If the ATMOS S 351 Natal is mounted on a trolley, the trolley
symbol (Fig. 38) is shown on the display. The trolley symbol
must be displayed during operation on a trolley. If the symbol
is not displayed, the liquid level in the collection jar cannot be
detected.

The ATMOS S 351 Natal starts up and begins to build up the
vacuum. The vacuum reached at any time is displayed. The
unit switches off when the fi nal vacuum is reached.
If the vacuum value exceeds 800 mbar it is possible that the
ATMOS S 351 is automatically vented and the vacuum value
is reduced to 800 mbar. A control circuit controls the unit during
operation so that it runs only when the vacuum is less than
the value set.
Observe the liquid level in the collection jar during suction.
Although the electronic fi lling level monitoring switches off the
unit when the maximum liquid level is reached, you should
change the collection jar or empty it when it is about 2/3 full
(including foam head).
Trolley operation
When using old trolleys (earlier than March 2000), this
symbol will not be displayed, even if the system is func-
tioning correctly. Our service department can convert the
trolley for you in this case.
Suction function
Connect the suction catheter, suction connector or suction
instruments.
Switch on the ATMOS S 351 Natal. Check that the indicator
lamp in the switch is illuminated.
Select the fi nal vacuum required using one of the arrow
buttons (
and
, Fig. 39). If the button is kept depressed,
the value changes more rapidly.
The maximum vacuum is set by pressing the Max button
(
, Fig. 39) .
If liquid has been sucked into the unit despite the level
monitoring and safety jar, the ATMOS S 351 Natal must
be returned to operation only after examination by a
service engineer.
