2.0 CONNECTION, START-UP AND OPERATION
2.1 Functions 2.2 Start-up
The Rationed AC 20/AC 30 is a particularly compact
suction unit for use in hospital, medical practice and at
home. The unit is driven by an electromotive,
maintenance-free piston pump. During operation, the
pump generates a vacuum in hose system and collection
jar; secretions or fluids are thus removed from the body
(e.g. by means of a suction catheter). The fluid is
collected in the collection jar. An mechanical overflow
safety (on the inner part of the collection jar lid) avoids
inadvertent suctioning of fluid into the pump head. The
final vacuum and, following, the air-flow rate can be
controlled by means of the supplied finger tip and the
vacuum fine adjustment. The vacuum value is shown
on the vacuum gauge. A bacterial filter avoids
penetration of bacteria and sucked fluid into the pump
chamber.
The Ratiomed AC 20/AC 30 is delivered ready for
operation. Prior to connecting the power plug, make sure
that the main voltage specified on your unit corresponds
with the in building voltage. First, insert the power cable
into the IEC power socket on the rear of the unit and
then into the wall socket. Set main switch to ‘I’. The
green pilot lamp in the switch must flash. Attach suction
hose to the connection on the collection jar lid (marked
with ‘patient’). Close the hose with the finger to check
whether vacuum is generated.
CAUTION!
The unit may be operated with inserted bacterial filter
and in upright position only.
Once the collection jar contains liquid the unit must be
placed into upright position. The inserted overflow safety
can function in upright position only, no matter whether
the unit is being used or not.
Before transporting the unit, make sure that the collection
jar lid fits properly.

2.3 Operation
When the Ratiomed AC 20/AC 30 is used for removing
body fluids of all kinds you should follow this procedure:
depending on the intended application, select a
suction catheter of the right size or use a suction
cannula;
connect the suction hose with the suction catheter by
means of a hose connector or directly attach the hose
to a suction cannula;
use the fine adjustment to set the vacuum and,
consequently, the air-flow rate acc. to your
requirements. Cannulae with exhaust air valve can be
used as additional control possibility.
During all suction procedures, always observe the fill
level in the collection jar (incl. foam). Never overfill the
jar. Rinse suction catheter, suction cannula and suction
hose with clean water after each suction procedure.
CAUTION!
Make sure that the collection jar is evacuated in time.
Generally, it must be evacuated after each finished
suction procedure.
When the jar is filled up the overflow safety reacts and
the unit stops sucking. In case of extensive foam
formation, liquid may reach the filter which will then
lose its air permeability and need to be replaced.
Evacuate the collection jar.
When secretion has penetrated the pump the
Ratiomed AC 20/AC 30 has to be maintained by a
service technician authorized by megro.

3.0 CLEANING AND SERVICING
3.1 Collection jar: how to evacuate it 3.2 Collection jar and housing:
how to clean them
Switch off the Ratiomed AC 20/AC 30. Remove
connecting hoses from the collection jar and withdraw the
collection jar incl. lid. Unscrew the lid and evacuate the
jar.
CAUTION!
Empty the sucked material in suitable waste water
systems only.
CAUTION!
Prior to cleaning the surfaces, remove power plug
from the unit.
Collection jar and collection jar lid can be rinsed under
running water or cleaned in an automatic cleaning
device.
3.3 Cleaning and disinfection
The unit can be wiped with a moist (not wet) cloth.
Basically, all parts which come into contact with secretion
must be cleaned and disinfected or sterilized after each
suction procedure. Hospital staff may determine other
cleaning, disinfecting and sterilizing agents and cycles.
Silicone hoses and collection jar parts (jar and lid) are
autoclave-safe (20 minutes at max. 121°C). These parts
may also be immersed in commercial disinfectants. The
hose adaptor (green) may only be cleaned with warm
water (up to 50°C).
If, contrary to expectations, the overflow safety does not
react and fluid penetrates the intermediate hose and the
bacterial filter, then the complete hose set (hose set S6
or S10, see consumables) must be replaced.
CAUTION!
Always comply on principle with the relevant
manufacturer’s information regarding ingredients,
concentrations and application of disinfectants!
The respective notes for use indicated by the
manufacturers must absolutely be observed!

13
3.4 Filter 3.4.1 Filter: general function
This suction unit may be operated with bacterial filter
only!
CAUTION!
A moist filter reduces the performance of your
Ratiomed AC 20/AC 30.
In this case, immediately replace the filter.
Recommendation:
The filter should be replaced every 1-2 weeks.
Please take care that there are always sufficient spare
filters available (see spare parts list).
Pay attention to maximum fill level in the jar in order to
prevent secretion from coming into contact with the filter.
The original bacterial filter for this unit:
protects the interior of the unit from contamination;
stops the flow of liquids due to its hydrophobic
features. Together with the mechanical overflow
safety this filter prevents sucking in of secretions into
the interior of the unit which would cause failure of the
Ratiomed AC 20/AC 30.
CAUTION!
Disposable part! The filter must not be cleaned. When
the filter is contaminated or moist it must be replaced
with a new one.
3.4.2 Filter: how to replace it
Removing the filter:
Remove filter and silicone hose from the attachment
on the unit. Take off the hoses and dispose of the
filter.
Inserting the filter:
First, connect the transparent side of the filter to the
intermediate hose. Then, attach the blue side of the
filter to the filter hose on the pump (see figure in
chapter 2.3).
CAUTION!
Important: The blue side of the filter must face the
unit.
