Set-up and putting into operation

When unpacking the device, please make sure to unpack the accessories as well.
Install the Laboratory hot plates on a flat, stable and non-slippery surface. The area under the Laboratory
hot plates must be non-combustible! An allround space of at least 0,5 m must be observed.
Insert a 10 mm ∅ tripod rod into the holder on the back (M8 female thread), then tighten the tripod rod
manually. In the case of the SLK 2-T and the SLK 6 Laboratory hot plates connect the temperature sensor
(Pt 1000 Resistance Thermometer) to the 4 mm sockets at the back panel of the device.
Prior to making the mains connection please check to ensure that the details on the specifications plate
match the mains voltage. Plug the mains cable to the integrated 'Europe' socket at the back panel of the
laboratory hot plates. After having connected the mains cable to mains, the central crossbar of the
7-segments display will light up to indicate that the laboratory hot plates are being supplied with mains
voltage. Some types of the hot Laboraty indicate the actual software version.

General, proper use

The decoration marks the centre of the heating zone. However, the surface will also be heated up outside
the decoration surface. You can interrupt the boiling process quickly by simply moving the boiling vessel
out of the hot zone to colder neighbouring areas.
The Laboratory hot plates are equipped with a residual-heat indicator << H >> which lights up immediately
after the hot Laboratory hot plates are switched off. Likewise, a residual heat will be indicated after approx.
10 seconds on the << 0 >> heating stage. As long as the<< H >> symbol lights up, the switched off boiling
zone of the Laboratory hot plates remains hot and can be used in an energy-saving manner. This residual-
heat indicator warns of the hazard of getting burnt. Caution! If you pull the mains plug out of the mains
socket, or if a power failure occurs, the residual-heat indicator is function-less. As soon as the heating
process is resumed, the residual-heat indicator will be activated again. Caution: Danger of burning!

!
The Laboratory hot plates should always be switched off after use.
After 3 hours of heating on heating stage << 9 >> without the sensor surface being touched, the safety cir-
cuit will switch back to heating stage << 8 >> to prevent the glass-ceramics material from overheating. The
over-temperature protection protects the Laboratory hot plates from excess temperatures.
If several sensors keys are touched within 1 second, the Laboratory hot plate interpretes these commands
as an operating error which is ignored (safety measure). There must be intervals of at least 2 seconds be-
tween touching the keys.
Please observe the cleaning and care instructions. In particular, you should keep the fields of the sensor
keys clean, since their soiling may be misinterpreted as a finger contact.
If sugar, plastic, or aluminium foil get on the hot spots of the heating zones, do not switch the Laboratory
hot plates off, but remove these matters immediately using a razor-blade scraper.
Caution: Danger of burning!
! !
After using the razor-blade scraper, retract the blade properly. Danger of injury! The heating zones should
be cleaned subsequently when cooled down.
First cleaning and heating-up
During first heating up of the Laboratory hot plates, or after a long period of non-use, a temporary smell
will occur as a result of the combustion of small dust particles and the evaporation of water inside the insu-
lation. To remove the accessible dust particles from the glass-ceramics material use a mild detergent to
clean the glass-ceramics surface. Subsequently, use a soft cloth to rub the surface dry.
