1.2 Product safety and dangers

The appliances described in this manual are technically sophisticated, manufactured using
high-quality materials and subject to many hours of testing in the factory. They reflect the
state of the art and comply with recognised technical safety regulations. However, there are
still risks involved, even when the appliances are used as intended. These are described below.

D33451 | Date 01/2018 7

For your safety

WARNING

After removing covers, live parts may be exposed. You may receive
an electric shock if you touch these parts. Disconnect the mains plug
before removing any covers. Only electrical engineers may work on
the electrical equipment of the appliances.

WARNING

When loading the appliance with an unsuitable load, poisonous or
explosive vapours or gases may be produced. This could cause the
appliance to explode, and people could be severely injured or poi­soned. The appliance may not be loaded with materials / test objects
that release toxic or explosive vapours when heated up (see also
chapter Intended use on page 8).

WARNING

Leaving the door open during operation can cause the appliance to
overheat or pose a fi re hazard. Do not leave the door open during
operation.

WARNING

Gas bottles may burst or explode at high temperatures. Keep the
gas bottles away from open fl ames. Store gas bottles below 50 °C
and ensure that the location is always well ventilated. Prevent water
from penetrating as well as backfl ow into the gas bottles. It is es-
sential that you read the safety notes and instructions of the gas
supplier.

WARNING

Condensation might cause a short circuit. After transport or storage
at high humidity conditions, the appliance shall be stored unpacked
at normal conditions for at least 24 hours. During this period of time
the appliance shall not be connected to the power supply.

CAUTION

Danger of suffocation. CO2 and N2 can have a suffocating effect
in high concentrations. In normal mode, the appliance emits small
amounts of CO

2

and N2 to its surroundings. You should therefore
ensure that the room in which it is installed is properly ventilated.
A ventilation rate of 250 m³ / h is required. Always close the stop
valve or pressure reducer on the gas bottles if the appliance is not in
operation.

CAUTION

High concentrations of CO2 can cause cold burns or frostbite. Avoid
contact with CO

2

gas to the eyes and skin.

8 D33451 | Date 01/2018

nel, e.g. work clothes and safety shoes.

1.5 Intended use

CO2 incubators ICO are intended for incubation of cell cultures or similar.
The appliance is not explosion-proof (does not comply with the German occupational health

& safety regulation VBG 24). The appliance may only be loaded with materials and substances
which cannot form any toxic or explosive vapours at the set temperature and which cannot
explode, burst or ignite.

The appliance may not be used for the drying, evaporation and baking of paints or similar
materials, the solvents of which could form an explosive mixture when combined with air. If
there is any doubt as to the composition of materials, they must not be loaded into the appli­ance. Potentially explosive gas-air mixtures must not form, neither in the working chamber nor
in the direct vicinity of the appliance.

Only feed distilled water as well as CO

2

and N2 into the chamber through the media connec-

tions on the rear of the appliance. Introducing other liquids or gases is not permitted.
The incubator may not be used for sterilisation purposes. It is not a steriliser according to the

German Law on Medical Products. Sterilisation programmes (see page 58) that are saved
in the appliance only serve to sterilise the appliance itself. Do not use them to sterilise medical
devices!

D33451 | Date 01/2018 9

For your safety

1.6 Changes and conversions

No unauthorised changes or alterations may be made to the appliance. No parts may be
added or inserted which have not been approved by the manufacturer.

Unauthorised changes or alterations result in the CE declaration of conformity losing its valid­ity, and the appliance may no longer be operated.

The manufacturer is not liable for any damage, danger or injuries that result from unauthor­ised changes or alterations, or from non-observance of the regulations in this manual.

1.7 Behaviour in case of malfunctions and irregularities

The appliance may only be used in a flawless condition. If you as the operator notice irregu­larities, malfunctions or damage, immediately take the appliance out of service and inform
your superior.

You can find information on eliminating malfunctions from page 41.

1.8 What to do in case of accidents

1. Keep calm. Act with determination and consideration. Pay attention to your
own safety.

2. Switch off the appliance and close the valves of the gas bottle.

3. Call a doctor.

4. Start first aid measures. If available: Call a trained first aid helper.

In case of contact with CO2 to the eyes and skin:

Rinse eyes out with water for at least 15 minutes. In case of cold burns, rinse with
water for at least 15 minutes. Cover over in a sterile way. Call a doctor.

When breathing in CO2 or N2:

High concentrations can cause suffocation. Symptoms may include a loss of mobility and
unconsciousness. The victim is not aware of suffocating.

Low concentrations of CO

2

can cause accelerated breathing and headaches.

Anyone affected should breathe fresh air, using a breathing device independent of recircu­lating air. Keep the person warm and calm. Call a doctor. In case of respiratory arrest, use
artificial respiration.

In case of gas leakage:

Leave the room immediately, warn others and ventilate the room. If you re-enter the room,
use a breathing device independent of recirculating air if it has not been established that the
atmosphere is harmless.

2.2 Description and function

Air is heated inside the appliance by means of large-area all-round heating.
The interior of appliances with passive humidity control is humidified with water that evapo-

rates from a tray that is placed inside. The interior of appliances with active humidity control
is humidified with water evaporating at a set rate from a tank by means of a hot-air generator
on the rear side of the appliance. The sterile hot air is introduced into the interior above the
fan and mixed with the air current. In appliances with water trays, a Peltier humidity trap in
the back of the appliance limits humidity. Appliances with active humidity are dehumidified
with a dosed supply of fresh air provided through a sterile filter.

Carbon dioxide (CO

2

) and nitrogen (N2 only for models with O2 module) are also injected into
the interior through sterile filters. Interior ventilation ensures a uniform distribution of the
gases, creating a homogeneous atmosphere. The oxygen concentration is controlled by intro­ducing nitrogen: If nitrogen is introduced, the concentration of oxygen decreases.

D33451 | Date 01/2018 11

people. Always attach the appliance to a wall with the tilt protection included in the delivery.
In case there is not enough space, do not put the appliance into operation and do not open
the door. Contact the Memmert service (see page 2).

1. Screw the tilt protection

onto the back of the ap­pliance as illustrated.

2. Bend the tilt protec-

tion upwards by 90 ° in
the desired distance to
the wall (consider the
minimum distance to the
wall, see Fig. 8).

3. Drill a hole, insert a plug

and screw the tilt protec­tion to a suitable wall.

NOTICE

The first time the appliance is operated, it must not be left unattended until it has reached the
steady state.

4.1 Connect the appliance to the power supply

WARNING

Condensation might cause a short circuit. After transport or storage
at high humidity conditions, the appliance shall be stored unpacked
at normal conditions for at least 24 hours. During this period of time
the appliance shall not be connected to the power supply.

Observe the country-specific regulations when making
connections (e.g. in Germany: DIN VDE 0100 with earth
leakage circuit breaker). Observe the connection and
power ratings (see nameplate and "Technical Data" on
page 13). Make sure to establish a safe PE conductor
connection.

Plug the provided power cable into the rear of the appli­ance and connect it to the power supply ( Fig. 9 ). Place the
power cable so that

► it is easily accessible at all times and can be pulled off quickly, for example in case of inter-

ference or an emergency;

► it does not represent a trip hazard;
► it cannot come into contact with any hot parts.

4.2 Establishing water supply

4.2.1 Water specifi cations

For humidification with a water tray or steam generator, only use: demineralised water (aqua
dem) in accordance with VDE 0510/DIN EN 50272 if you are working according to these
regulations (production conductivity ≥ 5 ≤ 10 μS/cm). You can buy battery water in accord-
ance with the VDE 0510 standard in all larger drug stores, supermarkets and hardware stores
as well as from wholesale traders. The VDE 0510/DIN EN 50272 standard has to be explicitly
specified on the label.

Otherwise, possible calcification in the steam generators, steam piping and steam generator
pumps could affect the correct functioning of the appliance.

Only use chlorine-free water with a pH value of > 5 and < 7.

4.2.2 For appliances with passive humidity control: inserting the water tray

Mount the provided sealing lip to the narrow side of the water tray (Fig. 10) and fill 1.5 cm to
2 cm of water into the tray (for specifications see section 4.2.1).

Place the water tray with the attached sealing lip in the centre of the appliance floor and
carefully push it towards the rear panel until the sealing lip is completely under the ventilation
opening, touching the rear panel along its entire length (Fig. 11). The sealing lip magnetically
adheres to the rear panel and returns the water condensing on the humidity limiter to the
water tray.

NOTICE

Important: make sure not to spill any water and make sure that no water flows past the water
tray and onto the floor, as this would cause the humidity to exceed the maximum values.

4.2.3 For appliances with active humidity control: Fill up and connect the water

tank

Fill the supplied water tank with water and use the enclosed tube to connect it to the “H2O”
connection on the rear of the chamber (Fig. 12).

4.3 CO2 and N2 connection

WARNING

Danger of explosion and poisoning when introducing gases/sub­stances other than CO

2

and N2. Only carbon dioxide (CO2) and ni-

trogen (N

2

) may be introduced into the appliance through the gas

connections on the rear of the appliance.

WARNING

Gas bottles may burst or explode at high temperatures. Keep the gas
bottles away from open fl ames. Do not store gas bottles at or above
50 °C and ensure that the location is always well-ventilated. Prevent
water from penetrating as well as backfl ow into the gas bottles. It is
essential that you read the safety notes and instructions of the gas
supplier.

CAUTION

Danger of suffocation. CO2 and N2 can have a suffocating effect
in high concentrations. In normal mode, the appliance emits small
amounts of CO

2

and N2 to its surroundings. You should therefore
ensure that the room in which it is installed is properly ventilated.
A ventilation rate of 250 m³ / h is required. Always close the stop
valve or pressure reducer on the gas bottles if the appliance is not in
operation.
