+40°C
-5°C
%
80%
30%
Temperature Humidity
Warning! Never operate a SA suction unit in the presence of flammable gas such as
anaesthetic agents. This is an Explosion hazard!
An anti-foam agent may be put into the SA 2, without disinfectant solution, before use to reduce the
possibility of frothing. It should not however, be placed into the SA 2 for extended storage periods.
3.4 Connection
The silicon service tube (∅6mm I/D with 3mm minimum wall thickness) must be connected between
the filter and the vacuum port on the SA 2 lid. The tube has an elbow connector on each end for
fitting to the filter and for fitting to the ‘VACUUM’ port of the SA 2. The silicon tubing used in
conjunction with this equipment is a replaceable item. It should be changed regularly according to the
level of usage and where it has become in any way contaminated or damaged.

Manual 160 Issue 06 Page 7 of 16
3.5 SA 2 Overflow Protection Valve
The SA 2 is fitted with an overflow valve designed to shut off the vacuum when the fluid level reaches
1750ml, this will stop suction from the suction unit. When the valve operates, the suction unit must be
switched off and the full SA 2 replaced by an empty one. For SA suction units with two collection
containers and where appropriate the full SA 2 collection container may be replaced by the second
SA 2 through operation of the changeover valve located on the top of the unit.
It should be noted that even after the overflow valve has shut off, fluid might continue to be drawn into
the SA 2 to an extent dependent upon the level of vacuum in the SA 2 at the time when the valve
closed.
Warning! The overflow valve may not operate fully against frothing. To reduce frothing
anti-foam agent may be used. Liquid sucked through to the pump will cause
damage - As a precaution, a hydrophobic filter should be fitted to prevent liquid
passing through.
3.6 Cleaning Procedure
Warning! Contamination may be present on any components. When cleaning or
replacing any part of the SA 2 appropriate protective clothing and gloves
MUST be worn to avoid contamination. Disposal of contaminated parts must
be according to local protocols.
Warning! Solvent-based cleaning agents or abrasive cleaners must not be used on any
SA 2. Minimise contact with cleaning solution and rinse well immediately with
warm water. Prolonged immersion of parts in water above 60°C causes loss of
material properties and must be avoided. Do not soak in dilute or neat
disinfectant, as this will cause damage.
Warning! The black ‘O’ seal is a re-usable item but must not be autoclaved.
The SA 2 collection container is made from Medical Grade Polycarbonate and is autoclavable up to
138°C. The SA 2 must be cleaned and sterilised between uses. The SA 2 is connected to the
aspiration unit via silicon tube and two vacuum connectors. The tubing and connectors are
replaceable items and should be changed regularly according to the level and type of usage and when
it has become in any way contaminated or damaged. The black ‘O’ seal is a re-usable item but must
not be autoclaved.
The SA 2 can be cleaned, disinfected and sterilised by most of the well-known methods employed in
practice. Under certain conditions, however, contact with cleaning, disinfecting and sterilising media
may cause some damage, which manifests itself in the form of stress cracking. This usually leads to a
reduction in mechanical strength. This manual contains no specific recommendations as to suitable
cleaning agents and disinfectants for the SA 2because the choice is many, and the composition of
such products can change.
In order to avoid mechanical stress to the SA 2, it is advisable not to clamp or stack them during
cleaning, disinfection or sterilization.

3.6.1 Cleaning of Jar and Lid
In many cases it is sufficient to clean with warm or hot water to which some weakly acidic, neutral or
weakly alkaline cleaning agent has been added.
•Cleaning is a pre-requisite for all types of decontamination. Sterilisation will not be
effective on a jar that is still soiled. In addition, proteinaceous matter may become
baked onto the surface.
•Gloves, apron and eye protection must be worn when cleaning by hand.
•The jar, lid and other parts must be separated before cleaning to ensure all
surfaces that may be contaminated are cleaned.
•Special attention should be paid to the overflow valve assembly and passageway
attached to the lid.
•Always pre-clean SA 2 parts under water and in a deep sink using detergent and
hot water to remove visible contamination - A soft brush may be used.
•Items must be examined after the cleaning process, to ensure that all visible soiling
is removed.
•Rinse well to remove any cleaning agent and avoid surface damage.
3.6.2 Cleaning of the ‘O’ Ring Seal
In many cases it is sufficient to clean the ‘O’ seal with warm or hot water to which some weakly acidic,
neutral or weakly alkaline cleaning agent has been added. The ‘O’ ring seal is a re-usable item but
must not be autoclaved. Thoroughly dry the ‘O’ seal after cleaning. Inspect the ‘O’ ring seal after
cleaning to ensure it is not cracked or damaged in any way. Replace if necessary.
3.6.3 Sterilisation
Sterilising by steam autoclaving -
•Ensure removal of all visible soiling.
•The SA 2 must be dried prior to sterilisation. This reduces the likelihood of lime
scale build up and ensures adequate steam penetration.
•The SA 2 jar should be inverted on the tray.
•Sterilise in a high temperature Autoclave at 138°C for a minimum of 3 minutes.
In contrast to standard autoclaving conditions, i.e., 121°C for 15 to 30 minutes, the SA 2 may be
subjected to temperatures up to 138°C, thus reducing the amount of time needed for sterilisation.
When sterilising with steam, germicides and detergents must be rinsed thoroughly from parts prior to
autoclaving. Failure to thoroughly remove germicides and detergents from the parts prior to
autoclaving may cause accelerated degradation. Permanent immersion of parts in steam causes loss
of material properties and must be avoided.
Care must be taken to ensure that the SA 2 parts are not damaged by substances added to the
boiler feed water, such as alkaline corrosion inhibitors, and that the SA 2 jar is positioned in such a
way that no condensation can accumulate inside it as this may also cause damage.
The SA 2 complies with ISO 10079-1 and will undergo 30 sterilisation cycles before deformation may
become visible. Stress cracking and fracture may occur after further autoclave cycles. As a rule, it is
possible to sterilize the SA 2 many times before gradual chemical decomposition reduces the
mechanical strength to a level where it is no longer adequate for its application. Sterilization tests
have shown that even after 100 cycles of 30 minutes each at 120 to 125°C, the material still retains
comparatively good impact strength.
Service UK Health and Safety Act – The unit must be decontaminated internally and externally and
certified as such before returning for service. Help Line 01932 355277
