Safety instructions
Safety instructions - performance of trials
Wear your personal protective equipment
in accordance with the hazard category
of the media to be processed. Otherwise
there is a risk from:
- splashing and evaporation of liquids
- ejection of parts
- release of toxic or combustable gases.
• Immerse external temperature sensors (PT 1000 ...) at least 20
mm deep into the medium or insert the sensor into the hole
provided for the purpose in the temperature control block.
• The PT 1000 external temperature sensor must always be in-
serted in the block / media when connected.
• Do not heat liquid media except with the block. Never pour
liquid media directly on to the heating plate!
• Safe operation is only guaranteed with the accessories de-
scribed in the ”Accessories” chapter.
• Always disconnect the plug before fitting accessories.
• Accessories must be securely attached to the device and can-
not come off by themselves. The centre of gravity of the as-
sembly must lie within the surface on which it is set up.
• Refer to the operating instructions for the accessories.
Safety instructions - power supply/ switching off the device
The appliance can only be disconnected
from the mains supply by pulling out the
mains plug or the connector plug.
• The device will automatically restart in mode B following any
interruption to the power supply.
For protection of the equipment
• The appliance may only be opened by experts.
• Do not cover the device, even partially e.g. with metallic plates
or film. This results in overheating.

and safety and accident prevention regulations
•Socket must be earthed (protective ground contact).
•Before starting the device for the first time, ensure that the
connector cable is suitable for the type of socket used and that
a safe protective earth connection is assured.
Risk of burns! Exercise caution when
touching the housing parts and the heat-
ing plate.
The heating plate can reach tem-
peratures in excess of 120 °C. Pay attention to the residual heat
after switching off.
The device may not be transported
unless it is cold!
Safety instructions - device arrangement
Do not operate the appliance in explo-
sive atmospheres, with hazardous sub-
stances or under water.
•Set up the appliance in a spacious area on an even, stable,
clean, non-slip, dry and fireproof surface.
•The feet of the appliance must be clean and undamaged.
•The voltage stated on the type plate must correspond to the
mains voltage.
•The socket for the mains cord must be easily accessible.
•The power supply cable and cables to the external sensors must
not be allowed to come into contact with the hot mounting
plate.
•Check the appliance and accessories beforehand for damage
each time you use them. Do not use damaged components.
Safety instructions - permissible media
Caution! Only media whose flashpoint
lies above the safety temperature limit of
130 °C may be processed or heated with
this device.
Beware of hazards due to:
- flammable materials
- combustible media with a low boiling temperature
- glass breakage
- incorrect container size
- overfilling of media (in a beaker)
- unsafe condition of container.
• Process pathogenic materials only in closed vessels under a
suitable extractor hood. Please contact IKA®if you have any
questions.
Only process media that will not react
dangerously to the extra energy produced
through processing. This also applies to any
extra energy produced in other ways, e.g. through light irradiation.
• Bear in mind the possibility of contamination that might lead
to undesirable chemical reactions.

Controlling the temperature via contact thermometer
The preferable method for controlling the average temperature
is with the contact thermometer. After the set point tempera-
ture has been adjusted, this results in a short heating-up time,
practically no temperature drift and only minor fluctuation in
temperature.
A 6-pin jack is located on the rear side of the instrument for
connecting the contact thermometer or the contact plug. The
electronics of the instruments returns a test current that must
flow via connector pins 3 and 5 for the heating plate to heat up.
Settings
For the detailed instructions for settings and limit values, refer to
the operating instructions for the instrument you are connecting.
The target temperature of the medium is set at the contact
thermometer. The heater buttons +/- (J) and (K) on the de-
vice can be used to preselect the required surface tempera-
ture of the heating plate.
Safety contact thermometers
acc. to DIN 12 878 class 2 or acc. Gerstel are connected with
a three-wire cable, the test current flows through the contact
thermometer.
Safety function
If the test current is interrupted because of e.g. breakage of
contact thermometer or falling out of the cable plug, the hea-
ting cuts off. The required plug allocation is indicated on a refe-
rence plate above the diode bushing.
Contact thermometer without safety circuit
acc. to DIN 12 878 class 0. The instrument only heats if the test
current circuit is closed by an electrical connection of the plug
pins 3 and 5.
Maintenance and cleaning
The device is maintenance-free.
Cleaning
For cleaning disconnect the main
plug.
Only use cleansing agents which have been recommended by
IKA®.

Repair
In case of repair the device has to be cleaned and free from any
materials which may constitute a health hazard. Please request
the form to "clearance certificate" from IKA. Or, use the down-
load-print the form to the IKA®website www.ika.com.
If you require servicing, return the appliance in its original
packaging. Storage packaging is not sucient. Please also use
suitable transport packaging.
Timer/Counter
After the device has been switched on, the "Timer/ Counter" but-
ton (I) can be used to toggle between timer mode and counter
mode.
Timer
Pressing the buttons "+" (G) and "-" (H) allows selection of a
time period of up to 99 hours and 59 minutes. Once the heating
function (F) is activated, the preset time starts to run. When the
total time has run down to 00 hours and 00 minutes, a warning
buzzer sounds for 30 seconds and in addition the display flashes.
The heating function is then deactivated.
Counter
When the heating function is stated by pressing the button (F)
the counter is activated. In counter mode the time is counted
upwards from 00 hours 00 minutes until the heating function is
stopped. The counter always starts from 00:00 hh:mm.
Selection of Timer/Counter
Pressing the button (I) toggles between timer mode and counter
mode. The mode can be activated only when the heating func-
tion is off.
