Disposal notes
Climate rating
The appliance contains reusable materials and should be
disposed of properly - not simply with unsorted household
refuse. Appliances which are no longer needed must be
disposed of in a professional and appropriate way, in
accordance with the current local regulations and laws.
The climate rating indicates the room temperature at which the appliance may be operated in
order to achieve full refrigeration performance.
When disposing of the appliance, ensure that the refrigerant circuit
is not damaged to prevent uncontrolled escape of the refrigerant
it contains (data on type plate) and oil.
Do not vent R134a into atmosphere.
R134a is a fluorinated greenhouse gas, covered by
Kyoto Protocol, with a Global Warming Potential
(GWP) = 1300.
•Disable the appliance.
•Pull out the mains plug.
•Cut through the connection cable.
•Disable safety lock.
Danger of suffocation due to packing material and plastic film!

Adjustment and operation
Detecting a power failure
The unit is switched on and off via the On/Off switch.
When the unit is first switched on, the display will flash. Pressing
the „⬆“ or „⬇“ key will cause it to stop flashing and remain permanently lit.
If there is a power failure, the display will start to flash again. This may
indicate that the temperature in the oven can no longer be held at
the working temperature, if the power is off for an extended period.
The controls will continue to operate normally, even if the display
is flashing. The flashing merely indicates that the unit has been
switched off and then back on again, or that the power supply
failed for a time and no key has been pressed since then.
It is important to note that the display will flash, even if the power
supply has failed for a very short period. It does not necessarily
mean that the temperature in the oven has deviated significantly
from the specified level.
The „Up“ key is used to increase the temperature
The „Down“ key is used to decrease the temperature
Temperature control and accuracy
The illustration shows the actual
temperature of 20.0 °C.
Setting the temperature values
When the unit is switched on, the display will initially show briefly
the type of oven and a version number. It will then display the
preset temperature, together with the symbol for the specified
figure (3 horizontal lines). After 5 seconds, this will be replaced by
the current, actual temperature.
The unit is preset in the factory to a working temperature of 20 °C.
If this is required to be 25 °C, for example:
Press the „⬆“ key once. The display will show the specified figure
which has been set, together with the symbol for the specified
figure (3 horizontal lines). Now press the „⬆“ key again, or
hold it down until the display shows the new figure required
(25 °C in this example). Then release the key. The display will show
the new setting for 5 seconds and will then display the actual,
current temperature.
If a lower working temperature is required, the same procedure
applies, using the „⬇“ key. The temperature can be adjusted in
steps of 0.1 °C between 2 °C and 40 °C.
If you wish to read the specified temperature but without changing
it, simply press the „⬆“ or „⬇“ key once and release it, so that the
display shows the specified figure instead of the current temperature.
The specified figure cannot be changed unless one of the keys is
pressed while the display is already showing the specified figure.
The preset temperature will not be lost if there is a power failure
of if the unit is switched off. The data are stored in an internal
electronic memory and are called up automatically when power is
restored or the unit is switched on.
The thermostatically controlled incubators are not specified according ASTM E 145 (9-point-measurement) or DIN 12880, part 2
Specifications are based on a one-point-measurement.
Test procedure
1. Place a sample bottle filled with 500 ml water with a stirring
rod on a stirring place and place it in the middle of a grid (5th
insert from the bottom).
2. Completely immerse the probe of the meter in the water sample
(according to the specifications of the meter). The probe should
not touch the bottle wall.
Specifications of the meter: Accuracy at least 0.5°C
Resolution at least 0.1°C
3. The temperature is read after 4 hours.
Trouble shooting
If the verification of the temperature accuracy is not successful the
following should be taken under consideration:
- The ambient temperature of the thermostatically controlled
incubator must match the climate rate (type plate).
- A certain circulation of air is necessary for the compressor to
work properly.
- The incubator should not be opened to often and / or for longer
period of time.
- Check the function of the two fans by visual inspection.
- Check the cooling device by setting 10 °C and wait for a significant change of the temperature in the sample towards 10 °C.
- Check the heating device by setting 40 °C and wait for a significant change of the temperature in the sample towards 40 °C.
- Depending on the sample temperature it can take up to 7 hours
for temperature stability at the set-value.
The air temperature in the cabinet may fluctuate by several degrees
centigrade. Nevertheless the actual temperature of the sample
fluctuates only by a maximum of ± 0.5 °C.
Other operation controls
On the front side of the temperature control unit there are
covered shock-proof sockets for the connection of BOD's
appliances or stirring apparates. The total load on the sockets
must not exceed 4,5 amps.
The thermostatically controlled oven and laboratory sockets are
protected by a fuse (6.3 A T) which is accessible from the front
panel of the unit.
The control unit is connected by means of a 4-pole plug on the
bottom of the incubator.
TC 140 G / TC 256 G_1 04/2014
When operating at a very cold thermostat setting, the interior rear
wall may ice up.
If a malfunction occurs during operation, check whether it is due
to an operating error.
In this case, the appliance must be defrosted manually.
•Pull out the mains plug!
•Leave the door of the appliance open while defrosting.
Defrosted water collects in an evaporator tray and is
evaporated automatically. Attention must be paid that
the defrosted water can drain off freely through the
drainage opening in the back panel of the incubator.
The drainage opening should, when necessary be
cleaned with the aid of a suitable device (e.g. bottle
brush). After defrosting mop up the remaining water
and clean the appliance.
Do not use any mechanical devices or other
artificial aids for defrosting other than those
recommended by the manufactur­er.
Clean the appliance at least twice per year.
Before cleaning always switch off the appliance. Pull out the
mains plug or switch off or unscrew the fuse.
•Clean the inside, equipment and outer walls with
lukewarm water and a little detergent. Do not use
abrasive or acid cleaners or chemical solvents.
You may be able to rectify the following faults yourself:
•Appliance does not function:
–Is the appliance switched on?
–Is the plug correctly fitted in the mains socket?
–Is the fuse intact? If necessary, replace with a new 6.3 A (slow).
•Loud running noise:
–Is the appliance set up firmly on the floor?
–Does the appliance cause nearby items of furniture or objects to
vibrate? Please note that noises caused by the refrigerant circuit
cannot be avoided.
•Correct display of inside temperature but no regulation to the
temperature setpoint:
–Is the temperature setting correct (see "Setting the temperature")?
– Is the ventilation system working properly?
– Is the appliance set up too close to a heat source?
If none of the above causes apply and you cannot rectify the fault
yourself. Contact your dealer or supplier, if necessary send in the
control unit or thermostat-controlled incubator for repair (original
packing if possible!).
Before undertaking any repair work disconnect plug from
mains! Only trained specialists should work on electrical
•Ensure that no cleaning water penetrates into the
elec­trical components or ventilation grille.
•The dust should be removed from the refrigeration
unit and heat exchanger - metal grid at the back of
the appliance - once a year.
•Do not damage or remove the type plate on the inside of the appliance. It is very important for servicing
The compressor and other parts may
still be hot from operation.
Do not use steam cleaners because of the risk
of injury and damage.
Shutting your appliance down
If your appliance is to be shut down for any length of time, switch
it off and disconnect the plug or switch off or unscrew the fuse.
Clean the appliance and leave the door open in order to prevent
unpleasant smells.
The permissible room temperature for storing the appliance
after decommissioning is between -10°C and +50°C.
Storing the appliance outside this temperature range can
damage the appliance and cause it to malfunction.
The appliance complies with the relevant safety regulations and
EC Directives 2004/108/EC and 2006/95/EC.
