• Read the operating instructions completely before starting up
and follow the safety instructions.

• Keep the operating instructions in a place where they can be
accessed by everyone.

•

Ensure that only trained staff work with the device.

• Follow the safety instructions, guidelines, occupational health
and safety and accident prevention regulations.

• Wear your personal protective equipment in accordance with
the hazard category of the medium to be processed. Otherwise
there is a risk of splashing liquids.

• Set up the device in a spacious area on an even, stable, clean,
non-slip, dry and fireproof surface.

• Prior to each use, always check the device for damage. Do not
use damaged components.

CAUTION

Only process and heat up media
that has a flash point higher than
the adjusted safe temperature lim­it of the heating bath that has
been set.
The safe temperature limit of the
heating bath must always be set
to at least 25 °C lower than the
fire point of the media used.

DANGER

Risk of burns! During operation,
the heating bath housing can get
hot.

•

When emptying the device use only the handles to carry and hold
it.

• Prior to filling or emptying the heating bath, the device must be
switched off and disconnected from the power supply at the
plug.

• Only fill or empty the heating bath when it is cold.

• Empty the heating bath prior to transporting it.

• Never operate the heating bath without tempering medium.

DANGER

The preferred tempering medium
in the heating bath is water (up to
approx. 80 °C) or the low-viscosity
silicone oils (50 mPas) with a flash
point > 260 °C are also permitted.
There is a risk of burning when us­ing tempering media with lower
flashpoints!

• Before use, calculate the optimum filling level of the tempering
medium! Pay special attention to the change in volume caused
by heating and the displacement that occurs when immersing
an object, for example, an evaporating flask.

• When using the heating bath in combination with a rotary
evaporator, the heating bath temperature must not be allowed
to rise to a value higher than the boiling point of the solvent
at normal pressure, since if the evaporating flask glass were to
break there would be a hazard due to liquid spraying out (for
instance breakage of the evaporating flask glass during distilla­tion of water using a silicone oil bath).

CAUTION

When working with the IKA rotary
evaporator, be aware of a hazard
arising from breakage of the evap­orating flask glass.

CAUTION

Be aware of a hazard due to lack
of grip on a wet evaporating flask,
in particular when operating the
IKA HB digital heating bath with
silicone oil!

• When using as a water bath, the use of demineralised water is
recommended.

• Always observe the minimum filling level of one litre when using
oil as the tempering medium.

• Ensure that the interfaces are not soiled.

• Beware of hazards due to flammable materials.

• 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.

• Do not operate the device in explosive atmospheres, with haz­ardous substances or under water.

• The device will automatically restart in mode C following any
interruption to the power supply.

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

• The socket for the mains cord must be easily accessible.

• The voltage stated on the type plate must correspond to the
mains voltage.

•

Socket must be earthed (protective ground contact).

• Protect the device and accessories from bumps and impacts.

• The device may only be opened by experts.

• Solvents can be hazardous to health. Therefore comply with the
relevant warnings and refer to the relevant safety data sheet
(Internet).

• If silicone oil is used as a tempering medium, in the event that
the evaporating flask fractures there is a risk that on mixing with
the aqueous solvents (contents of the evaporating flask) the hot
oil will foam up and spurt out in conjunction with a rapid in­crease in volume (formation of bubbles by the solvent).

Safety circuit

The adjustable safety circuit prevents the temperature of the heat­ing bath from getting too high as a result of:

- a controller error,

- the rotating/pressing knob having been accidentally turned.
Once the safety temperature has been reached, the device switch­es off permanently.
Furthermore, dry running of the heating bath is detected. The de­vice switches off permanently.
The dry running function detects both accidental heating of the
heating bath without liquid and dry running caused by water
evaporation starting at a set temperature of 60 °C. The error mes­sage E 26 appears and the heating bath is switched off perma­nently. To remedy this error, see “Error codes”.
When the safety circuit is set, an upper temperature limit between
50 and 190 °C is defined.

• Silicone oils as tempering media
When increased safety is not necessary the temperature of the

safety circuit stays at 190 °C.

Temperature of the tempering medium rises to a maximum of

190 °C in the case of an error. Then the safety circuit switches
the heating bath permanently off.

• Demineralised water as the tempering medium
When increased safety is not necessary, the adjustment knob of

safety circuit stays all the way to the right. As long as there is any
demineralised water in the heating bath, the temperature of the
tempering medium rises to a maximum of 100 °C, in the case of

Operating mode A

Controlling the medium temperature

The medium temperature is limited by the set safety temperature,
controlled by means of a PID controller and measured by the PT 1000
temperature sensor, and the medium is heated up as quickly as pos­sible without overshooting to the set temperature.
The PID controller adapts to the different tempering media and en­sures optimum temperature control with minimum temperature drift
and fluctuation.
Optimum control is only achieved when the medium is mixed using a
rotating evaporator piston.

- Set the desired medium temperature between room temperature
and 180 °C by turning the rotating/pressing knob (C). The max.
medium temperature setting is the safety temperature minus 10
°C.

- Start the heating function by pressing the rotating/pressing knob
(C).

- An animated heating symbol appears on the display. (Fig. 9)

- The heating bath is heated up to the set temperature.

- The set and actual temperature referred to the medium are shown
on the display. (Fig. 9)

Select tempering medium

- If a target value > 90 °C is set, the PID controller is adapted specially
for oil.

- The “OIL“ symbol appears on the display. (Fig. 11)

- If the target value is reset to 20 °C the PID controller is adjusted
again specially to water.

- The “OIL“ symbol will disappear from the display. (Fig. 9)

The heating bath transfers data via IR interfaces. These interfaces are
located on the left display side of the heating bath or on the right
side of the drive unit. Do not place any objects between the two
operating units as otherwise the data transfer may be interrupted!
