or film. This results in overheating.

• Ensure that the base plate is kept clean.

• Protect the appliance and accessories from bumps and impacts.

• Observe the minimum distances between the devices, be­tween the device and the wall and above the assembly (min.
800 mm), see Fig. 2.

Wear your personal protective equipment
in accordance with the hazard category
of the media to be processed. Otherwise

The appliance can only be disconnected
from the mains supply by pulling out the
mains plug or the connector plug.

WARNING

- 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
questions.

DANGER

Timer/Counter

After the device has been switched on, the "Timer/ Counter" but­ton (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.

Controlling the temperature via contact thermometer

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 func­tion is off.

The preferable method for controlling the average temperature
is with the contact thermometer. After the set point tempera­ture 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 tempera­ture of the heating plate.

Maintenance and cleaning

The device is maintenance-free.

For cleaning disconnect the main
plug.
