1.4 Function
The ATMOS S 351 OT is a mains-operated medical suction device. The device is operated
with an electronically controlled, maintenance-free diaphragm pump.
During operation, the pump generates a vacuum in the secretion canister and hoses,
bymeansofwhichsecretion,bloodandbodyuidsarewithdrawnbysuction.Theuid
iscollectedinthesecretioncanister.Thebuttonsallowyoutosetthenalvacuumand
thus the suction capacity in steps. The set value can be read on the vacuum display.

9Introduction
Oncethenalvacuumisreached,thepumpturnsoandonlycontinuesworkingif
suctioncapacityfallsbelowthenalvacuumvalue.
Intermittent suction is used for gastric drainage. Suction is divided into four phases that
repeat periodically (build-up time, holding time, release time, pause). The user can set
the duration of the individual phases as well as the level of vacuum to be built up in the
user menu.
1.5 Intended users
The device may only be used by trained and instructed medical professionals.

3.3 Connecting to the mains power supply
1. Check whether the voltage and frequency data listed on the device correspond to
the values of the mains power supply.
2. Connect the device to the mains.
3. Secure the power cable against accidental removal by using the safety clamp.
For surgical procedures, we recommend additionally connecting the device via the
connection to the potential equalisation of the examination room.
3.4 Connecting the secretion canister system and hoses
1. The anti-foaming device must be placed on the
ll-levelsensorforstronglyfoamingsecretion.
2. Slide the secretion canister lid with the release
button pointing forward onto the secretion
canister.
Make sure that the lid rim is under the bead of
the secretion canister. This seals the secretion
canister tightly and the desired vacuum can be
built up in the secretion canister.
3. Press the locking handle downwards until it
clicks into place.
4. Hang the secretion canister in the left or right
support for the canister system.
Using the support for the canister system for
purposes other than what it was designed for can
cause malfunctions.
