1.0 General Notes Concerning Areas of Application and Mode of Operation

The devices can be used in all laboratory fields in which constant temperatures are

required, e.g. for the cultivation of plant cells.

Areas of Application (Examples):

• Fast propagation of homogeneous cultures

• Production of disease-free, resistant plants

• Genetic improvement of useful plants

• Production of secondary natural substances and biogenous pharmaceutics

The Bühler incubator hoods can be used as independent incubator chambers. Combined

with Bühler shakers they are complete incubator shakers.

The incubator hood is placed directly on the housing of the shakers listed above so that no

additional space is required for the incubator hood.

Smaller devices can be placed completely under the incubator hoods.

If you have any questions, please do not hesitate to contact our export sales department:

(Tel.: +49 7471 / 9864-22, Fax +49 7471 / 9864-75).

2.0 Transportation Instructions

Safe transportation of the devices is only ensured if original packaging is used. If they are

bumped hard or put down roughly, damages can occur.

ATTENTION: Do not lift the device at the handle ! Transport the device by

holding it at the housing (bottom) only!

3.0 Installation and Connection

3.1 As independent constant temperature chamber:

Place the device on a level, smooth and firm surface.

The electrical connection data and operating voltage are listed in the Technical Data.

ATTENTION: The device may only be connected to supply voltage with earth

protection!

When installing the device make sure that it is protected

against splash water.

3.2 Fixation of the Incubator Hood on a Shaker:

A fixing angle and corresponding screws are delivered with the incubator hoods. The fixing

angle must be screwed to the drillings at the back of the shaker with the recessed cheese

head screws.

At the left and at the right of the fixing angle there are 2 fixing cones which fit in

corresponding drillings at the bottom of the incubator hood. The hood must be placed on

the shaker that the drillings slide over the fixing cones and thus is secured.

Edmund Bühler GmbH - EXBED\THE00.DOC – 04/05 5

The incubator hood is connected to mains with the mains plug (see above warning). With

the short cable (delivered with the device) the incubator hood is connected to the shaker.

The shaker does not need a separate mains plug as its current supply functions via the

incubator hood.

ATTENTION: If both devices (shaker and hood) are connected to mains

separately, the automatic cut-off for the shaker does not work

when the incubator hood is opened.

The combination of a shaker type KS 15 with universal tray for spring clamps and incubator

hood TH 15 may require higher distance rings between shaker and tray, otherwise the tray

could be blocked. Please contact us if this is the case.

• The incubator hood is switched on (I) or off (0) by means of the mains switch.

(After having switched the mains switch on, the temperature control runs a self test

which lasts approx. 3 seconds.)

• The display (7) shows the actual temperature.

• Adjust the required temperature (set value) with keys (3) or (4). The display returns to

the actual temperature. The device is heated up. The control lamp at the right

underneath the display is illuminated as long as the heating is active. When the set

value is reached, the control lamp blinks.

• Press keys (3) or (4) once to control the set value on the display.

• Press key (5) once to see the unit of notation, „°C“.

ATTENTION: The keys (5) and (6) are nearly completely blocked and only

serve for programming the controller in our works !

Edmund Bühler GmbH - EXBED\THE00.DOC – 04/05 7

At the incubator hood TH 30 2 additional pairs of keys serve for switching light (8) or UV

light (9) on or off.

4.3 Safety Cut-off when the Incubator Hood is Opened

When the incubator hood is used as incubator shaker in combination with a shaker, the

shaker is automatically stopped for reasons of safety when the hood is opened. The UV

light extinguishes (only TH 30).

ATTENTION: The safety cut-off only works when the devices are correctly connected

(see page 6) !

New start of the shaker after closing of the hood:

Analog models:

(No. 6171 000, 6173 000,

6166 000, 6101 000,

6103 000, 6105 000)

Control models:

(No. 6170 000, 6172 000,

6167 000, 6100 000,

6102 000, 6104 000)

When the hood is closed, the shaker starts

again automatically. (The timer is not

stopped when the door is opened !)

Mode A:

Speed and time must be newly set.

Mode B and Mode C:

The set program must be restarted by

pressing the ok key.

5.0 Maintenance and Servicing Instructions

The devices are maintenance-free. Excessive soiling should be avoided.

In case of failure, please contact the technical service department of the Edmund Bühler

GmbH.

The device is protected against overload by means of a fine fuse (see technical data).

The fuse holder is located at the back of the device underneath the mains plug. Pull out the

fuse insert and exchange the fuse.

ATTENTION: Before removal of the fuse insert disconnect the mains plug !

5.2 Overheat Protection

The devices are equipped with a thermal overheat protection. Should the temperature rise

up to 100°C due to a defect of the control, the heating is automatically cut off in order to

the technical service department of the Edmund Bühler GmbH , together with a detailed

description of the defect (address: see above).
