operators who have to be instructed, but also as an ongoing

source of reference. These instructions will assist in avoi-

ding danger and in reducing repair costs and downtime.

In addition, they will increase reliability and the life of the

equipment. For these reasons, the operating instructions

must always be available near the equipment.

Please read Chapter 2.0 „Safety Information“ before initial

start-up so that you are prepared for any potentially dan-

gerous situations.

The following applies in all cases:

Careful and prudent work is the best protection against

accidents!

The operational safety and availability of the equipment

depend not only on your ability, but also on care and

maintenance of the ATMOS S 351 Natal. For this reason,

regular cleaning and maintenance work is essential. Major

maintenance and repair work must be carried out only by

experts authorised by ATMOS. Please insist that only origi-

nal spare parts are used for repairs. This will guarantee that

1.2 Function

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.

The ﬁ nal vacuum required and thus the suction power can be

preselected in steps with the press of a button. The ATMOS S

351 Natal produces this vacuum with the aid of a micro-proc-

essor-based controller. The pump switches off when the set

value is reached. A control circuit ensures that the pump only

runs when the vacuum is less than the value set.

The electronic ﬁ lling level control, a safety jar (optional) and a

bacterial ﬁ lter prevent secretions being sucked into the unit.

Various monitoring and control functions increase the ease

of operation of the ATMOS S 351 Natal and ensure safe use.

These are, for example:

– Electronic ﬁ lling level monitoring of the collection jar which

provides visual and acoustic signals when the maximum

level is exceeded.

– Electronic ﬁ lter monitoring signalling a blocked (clogged)

ﬁ lter audibly and visually.

– A monitoring function which checks all main equipment

functions at regular intervals and activates a service re-

quest indicator if a fault is detected.

All components which come into contact with the secretion,

such as hoses, collection jar, lid system can be autoclaved

(up to 134

o

C, 4 min.).

A special equipment trolley can be supplied for mobile use.

 The vacuum must be built up slowly in a controlled manner

for vacuum extraction.

 The user must continuously check the vacuum during

vacuum extraction.

 If the vacuum cannot be reduced despite correct adjust-

ment of the equipment (defective auxiliary air valve), we

recommend closing the suction hose between pump con-

nection and bacterial ﬁ lter in an air-tight manner (pinch) and

then removing the suction hose from the pump connection

or cutting through the suction hose on the pump connection

with a scalpel. Then carefully let air back into the suction

hose (carefully release the pinched suction hose) so that

the vacuum is removed as slowly as possible.

 The ATMOS S 351 Natal version for vacuum extraction on

trolley 320.0070.0 must not be used as ﬂ uid suction unit for

operations as the electronic collection jar overﬂ ow monitor

on this trolley does not work.

 The buffer container for vacuum extraction must have a

volume of at least 1 litre.

 During vacuum extraction, the automatic mode can be

disabled by operation of the foot regulator.

 Prior to and during vacuum extraction, pay attention that

connection hoses are not kinked and that no blocked ﬁ lter

is used. Prior to each application, check whether the ﬁ lter

is blocked.



Vacuum extraction may not be possible at elevated altitudes

as it may not be possible to achieve the vacuum required.

Please see the appropriate table for this. It is at the discre-

tion of the specialist whether an operation using the suction

unit can be carried out at the ﬁ nal vacuum obtained.

 The jar overﬂ ow safety is not active during vacuum extrac-

tion.

 In case of a failure of the mains power supply or acciden-

tal switching off of the equipment during extraction, this

must be aborted and production of the vacuum has to

be re-started after the equipment has been successfully

restarted. The best way to do this is by pinching the suction

hose to maintain the vacuum in the cup, venting by pressing

the END button and building the vacuum again (pressing

the extraction cup button) and then applying the vacuum

by releasing the pinched hose. No venting must take place

while the equipment is switched on again. The control unit

continues to build up the vacuum or holds the vacuum.

 Only approved extraction cups with CE marking in accor-

dance with RL 93/42 must be used.

 The system must not be ventilated suddenly with simul-

taneous pulling on the extraction cup.

 If the ﬁ nal vacuum set is not achieved, the ATMOS S

351 Natal will not issue an audible signal „ﬁ nal vacuum

achieved“.

 The doctor treating the patient is responsible for the pro-

per surgical procedures and technology. A trained doctor

has to decide in each case whether the treatment is appro-

priate and how to carry it out.

 The ATMOS S 351 Natal may be used only by trained staff

under supervision (IEC 601-1 / EN 60601-1).

 The ATMOS S 351 Natal meets the requirements of the

standard IEC 601-1-2 / EN 60601-1-2 „Electromagnetic

compatibility – medical electrical equipment“ with regard

to resistance to interference.

 Always set up the equipment in such a way that the operator

can easily see the front panel and can reach it comfortably.

The equipment must be placed on a ﬁ rm, level surface.

 The ATMOS S 351/S 351 Natal/S 351 Ophthal has been

designed in accordance with IEC 601/ EN 60601. The

equipment conforms to VDE Safety Class I. It must only

be connected to a properly installed earthed socket.

 Before connecting the equipment, check that the values

for voltage and frequency indicated on the equipment

correspond to those of the mains supply.

 Use only correctly installed mains sockets and extension

cables.



Check equipment, collection jar, power cable, acces-sories,

connection cables and hoses for damage before start-up.

Damaged cables and hoses must be replaced immediately.

Check before use that the unit functions properly.

 To disconnect the equipment from the mains, always pull

the plug out of the wall socket ﬁ rst. Only then disconnect

the cable from the unit. Never touch plug or cable with wet

hands.

 After transport at low temperatures, the equipment must

be left at room temperature for up to six hours before initial

start-up. If the equipment has not been acclimatised, it must

not be operated as the diaphragms of the pump could be

damaged.

 When switching on the unit, a high vacuum value might be

present.

 When switching on the unit, a high vacuum value might be

present.

 This product is not re-sterilisable. Repeated reuse of

components which are marked with a is forbidden.

In case of repeated reuse these components lose their

function and there is a high infection risk.

2.0 Safety information

 The suction hose must never come into direct contact

with the patient. A suction catheter, suction attachment or

medical suction instruments must always be used.

 Too high vacuum values may lead to tissue damages.

 Only use transparent hoses or hoses destined for vacuum

extraction.

 The environmental conditions listed in the speciﬁ cations

(chapter 10.0) must be observed.

 The ATMOS S 351 Natal must only be operated in rooms

designated for medical use. It is not designed for use in

potentially explosive areas (M and G) and in oxygen rich

environments. Potentially explosive areas can arise from

use of ﬂ ammable anaesthetic agents and agents used for

cleaning and disinfecting skin.



If demineralised/slightly mineralised water or tap water is

sucked off, the overﬂ ow monitoring of the ATMOS S 351

Natal does not function reliably as it works on an electrical

basis.

 Do not allow liquid to enter the equipment. If liquid has

entered the equipment, it must be inspected by a service

engineer before further operation.



When using on a patient (e.g. during surgery), an additional

equivalent unit should be ready in case of failure of the unit

(backup suction unit).

 The level of vacuum preselected and the selection of addi-

tional products must be as instructed by the specialist for

all applications on a patient, e.g. for vacuum extraction.

 These operating instructions correspond to the design of

the equipment and the latest version of the safety standards

at the time of printing. All property rights are reserved for

the circuits, processes, names, software programs and

equipment listed.

 Particularly important notes are placed in a frame in these

instructions.

 The software detects a full collection jar or „shorting bet-

ween the contact terminals“ and issues a warning at regular

intervals. This does not interrupt the process of vacuum

extraction.

 Please dispose properly of all packaging.

 Please note:

A medical insulating transformer with earth leakage

monitor or any similar safety system acc. to EN 60 601-1 is

required, if several devices are connected over one com-

mon power supply. The transformer must correspond to the

power consumption of all the devices to be connected.

ATMOS do not accept liability for injury to persons

or damage to equipment if

– non-original ATMOS parts have been used.

– the information in these operating instructions

has not be observed.

– installation, adjustment, changes, extensions

and repairs have been carried out by persons

not authorised by ATMOS.

5.0 Operation

5.1 Basic Operation

5.1.1 Switching on

After switching on, the VE mode is active. The adjustments for

the vacuum to be generated (ﬁ nal vacuum) and the available

time (build-up time) correspond to the adjustments made in the

service menu (see chapter adjustments 5.3, page 28).

Exception: If there is already a vacuum present when switching

on, this value is assumed as start value for vacuum gener-ation.

Build-up time will then decrease accordingly.

At factory, the ﬁ nal vacuum is adjusted to -80kPa and

build-up time to 120s.

Graphics display

All operating states are shown on the graphics display.

Please ensure that the following parts have been

reprocessed before treating a new patient:

– suction hose including suction attachment or suction

instrument,

– collection jar lid and double socket nipple,

– connection hose to safety jar as well as safety

jar and bacterial ﬁ lter.

Check before each use whether the bacterial ﬁ lter has

to be replaced. You must use only a clean and dry ﬁ lter.

The electronic ﬁ lter monitoring signals when the ﬁ lter is

blocked (clogged).

The suction hose must never come into direct contact

with the patient. A suction catheter, a suction connector or

medical suction instruments must always be used.



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 g. 13) appears in regular intervals.

In suction mode, the pump is switched off when the maximum

ﬁ lling level is reached. The device gives an audible signal and

the indication for full jar (ﬁ g. 13) appears.

The maximum ﬁ lling level is reached when the liquid comes

into contact with the sensor (

, Fig. 3, page 11) in the closure

system. If a large amount of foam is generated, you should ﬁ t

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

connecting nipple), the unit switches on again.

Changing unities

The display of the ATMOS S 351 Natal can be adjusted to

3 unities: mbar, mmHg and kPa. This switching-over is descri-

bed in chapter 5.3, page 28.

Electronic ﬁ lter monitoring

The ATMOS S 351 has an electronic ﬁ lter monitoring which

monitors whether the ﬁ lter is blocked. The pump does not

switch off when the ﬁ lter blocked state is detected so that work

can continue. Change the ﬁ lter as soon as possible or clean the

ﬁ lter in accordance with the instructions in chapter 6.0 when

this message is displayed.

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.

Fig. 15. Display directly after switching on

Function vacuum extraction

For vacuum extraction, we recommend to use a small coll-

ection jar (1.5 l) to enable a quick generation of the required

vacuum value.

Automatic vacuum build up

During automatic vacuum build up, the vacuum is gener-ated

evenly and ﬁ nal vacuum is reached in the preset time (standard

adjustment = 120s). For changing this vacuum build-up time,

refer to chapter 5.3 Adjustments, page 28. During vacuum

generation, the green LED ﬂ ashes. When the ﬁ nal vacuum

is reached the device gives an audible signal and the green

LED lights up constantly.

The device offers the possibility to select between a fully

automatic vacuum build-up (VE Auto Mode) and a semi-

automatic vacuum build-up (VE Semi Mode) (see chapter 5.3

Adjustments, page 29).

The fully automatic vacuum build-up is standardly pre-

set.

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.
