Safety Notes
6
The temperature controlling i.e. immersing of test tubes,
Erlenmeyer flasks or similar objects directly within the
unit constitutes normal circulator practise.
We do not know which substances are contained within
these vessels. Many substances are dangerous:
•inflammable, easily ignited or explosive
•hazardous to health
•environmentally unsafe
You alone are responsible for the handling of these sub-
stances! Our advice:
•If in doubt, consult a safety specialist.
•Read the product manufacturer’s or supplier’s
“
EC – SAFETY DATA SHEET ”
•Read relevant regulations concerning dangerous
materials
•Observe relevant guidelines for laboratories in your
country
The following measures were taken for the protection of
the operator:
•Protection Class I according to VDE 0106 T1
i.e. protection against electric shocks by grounding all
parts which carry the risk of electric contact.
The device must only be connected to mains recep-
tacles with a protective ground.
•Protection IP 20 according to EN 60529
i. e. regarding the protection against accidently touch-
ing live parts and damage by foreign matter, it has been
ensured that foreign bodies with a thickness or diame-
ter of more than 12 mm cannot penetrate.
No special precautions were taken against the pe-
netration of water and dust. The device should there-
fore not be used in a dusty atmosphere or in the neigh-
borhood of spray water.
Do not insert wires or tools in any of the openings.
Complete separation from the mains is required
when:
•all dangers caused by this device are to be
avoided,
•cleaning is carried out,
•repairs or maintenance by specialist personnel is
about to be carried out
Complete separation means:
Pull out the mains plug!

Unit Description

5. Unit Description
5.1 Safety features
The comprehensive safety system is designed on the princi-
ple of the concept of the “single fault” (EN 61010). This as-
sumes that two separate faults do not occur simultaneously.
This system therefore offers protection against
one (single)
fault. This one fault will effectively occur automatically if
you...
•do not read this manual,
•do not correctly set the excess temperature protection,
i.e. your safety reserves have already been used up.
5.2 Safety element
The unit is equipped with an excess temperature protection.
The unit can only be used with non-flammable liquids such
as
water or water with antifreeze .
The safety element measures the surface temperature of the
heating element. If this exceeds a certain temperature (due
to e.g. a leakage in the liquid circuit or a liquid shortage), the
safety element is triggered.
If a safety feature is triggered…
•fault display lights indicate the fault,
•the safety-relevant components of the heating unit
(heating element ) are switched off immediately i.e. the
safety circuit transfers the unit to a stable, safe condi-
tion,
•the water in unit gradually adjusts to ambient tempera-
ture.
5.3 Applications
Temperature controlling and shaking of samples directly in
the bath vessel.The samples have to be inserted into flasks
or beakers.

6. Unpacking / Setting Up
6.1 Transportation damage?
•Notify carrier (forwarding merchant, railroad) etc.
•Compile a damage report.
Before return delivery:
•Inform dealer or manufacturer
(Small problems can often be dealt with on the spot).
6.2 Information concerning the CE sign
HAAKE circulators and cryostats carry the CE sign which con-
firms that they are compatible with the EU guideline
89/336/EEC (electromagnetic compatibility). The tests are car-
ried out according to module H (official sheet L380 of the Euro-
pean Community) as our quality assurance system is certified
according to DIN / ISO 9001.
It was tested according to the strict EMV test requirements of
the EN61326 (EMV requirements for electrical equipment for
measuring technology, conduction technology and laboratory
usage). This means it was tested for interference resistance
and interference emission according to industrial conditions.
The following basic standards were applied in detail:
Interference resistance:
EN61000–4–2 electrostatic discharge
EN61000–4–3 electromagnetic fields
EN61000–4–4 fast transients
EN61000–4–5 surge voltages
EN61000–4–6 wire–guided HF–signals
EN61000–4–8 magnetic field of mains frequency
EN61000–4–11 voltage drop/short–time interruption
Interference emission:
CISPR16/class A wire–guided interference emission
CISPR16/class A radiated interference emission
The application in industrial environments is thus possible.
A declaration of conformity is supplied with the ordered unit on
request.
Our strict standards regarding operating quality and the resul-
ting considerable amount of time and money spent on develop-
ment and testing reflect our commitment to guarantee the high
level of quality of our products even under extreme electroma-
gnetic conditions. Practice however also shows that even units
which carry the CE sign such as monitors or analytical instru-
ments can be affected if their manufacturers accept an interfe-
rence (e.g. the flimmering of a monitor) as the minimum opera-
ting quality under electromagnetic compatibility conditions. For
this reason we recommend you to observe a minimum distance
of approx. 1 m from such units.
The CE–sign also certifies the conformity with the EU–directive
72/23/EWG (low voltage regulation). The applied standards
are EN 61010–1 and EN 61010–2–010.

8. Assembly/Connecting Up
8.1 Connecting the platform to the guide rod
Lift left end of the platform (11) until the rubber connection
(10) at the bathbottom can be picked up and placed over the
pin at the underside of the platform.
8.2 Connecting to a mains socket
The unit should only be connected to a grounded mains sok-
ket. Before the unit is actually connected to the mains,
please compare the voltage indication on the name plate.
Voltage tolerances up to +/– 10% are acceptable.
8.3 Changing the mains plug (e.g. for Great Britain)
This should only be carried out by qualified spe-
cialist personnel!
The mains cable wires have the following colors:
Brown = Live
Blue = Neutral
Green/Yellow= Earth
8.4 Fuses on the unit
All units are equipped with automatic thermally-triggered
fuses.
If the fuse has triggered…
•the fuse does not have to be exchanged – resetting suf-
fices;
•a white marking is visible;
•a certain cooling down time should be allowed (approx.
5 min) before the (dip) switch can be pressed again.
Do not use tools; do not use force. Both destroy the
fuse.
If the fuse should be triggered again after resetting,
the unit probably has a defect. In this case the unit
should be sent in for servicing.

Setting up and Starting
12
9. Setting up and starting
9.1 Attaching clamps for vessels to the platform (11)
Spring clips can be supplied to secure round vessels, e.g.
Erlenmeyer flasks or beakers, to the platform.
Maximum clamp number see chapter 11.
9.2 Filling in the bath liquid
Liquid level: Can be selected anywhere between 50 and
180 mm (Thus, filling level dependent on objects used in the
bath.)
Only use
water or water with antifreeze .
9.3 Ideal operating conditions for the shaking
movement
The following should be considered in order to warrant ideal
operating conditions:
a) Type and level of the bath liquid.
b) Number, size, and weight of the test vessels.
c) Amplitude of the shaking carriage movement.
d) Number of carriage cycles per time unit
(shaking frequency).
The limiting conditions for the shaking movement:
1) Too large a shaking movement will cause high
waves on the bath surface so that the liquid will
splash over the top.
2) Large and heavy test vessels are attached to the
platform and the amplitude and /or the frequency
are too high. This means an overload for the
shaking drive:
An overload could lead to a standstill of the driving
motor and eventually to its destruction if such
operating conditions are kept up over a longer
period of time.

!
Setting up and Starting
13
The following rule will help to arrive at ideal operating condi-
tions:
At the beginning of the test, a small amplitude and a small
frequency should be selected. Then the values of these two
parameters may gradually be increased until the contents
of the test vessels are sufficiently shaken and mixed.
The shaking mechanism is also activated when the unit is
switched on. Please observe the notes above regarding the
shaking movement. It should especially be ensured that the
shaking motor is not blocked due to the choice of unsuitable
shaking motor parameters.
If the SWB25 is only to be used as a waterbath, the rubber
connection piece (10) of the platform (11) should be
removed.
9.4 Operational safety
The units are provided with an excess temperature safety
circuit, the cut-off temperature of which has to be set at the
dial button (5). In case of a temperature control malfunction
which could overheat the bath, the heater of the water bath
will be cut off. The malfunction indicator light (4) will then
come on.
9.5 Draining
The unit is drained at the nozzle 13.
1Place a suitable vessel underneath nozzle.
Bear in mind that the liquid will run out in a slight arc.
2Turn plug slowly until it becomes disengaged from the
thread.
The liquid will start to run out.
3Possible residues can be drained by tilting the circula-
tor slightly.
Hot heat transfer liquid should not be drained!
When certain conditions make draining necessary,
please act safety conscious: Wear protective
clothing and protective gloves!

The display 19 lights up when the heating is switched on (set
temperature is higher than the actual temperature).
⇒display 19 lights up constantly during the heating up
phase,
⇒display 19 flashes on and off during the control phase.
The display 19 does not light up if the heating is not activated
(set temperature is lower than the actual temperature).
The heat transfer is carried out by convection from the
heated bath bottom upwards. There are therefor small tem-
perature gradients in the bath from the top to the bottom or
from the bath side to the bath middle. This should be
accounted for if a correction of the set temperature should be
necessary.

12. Excess Temperature Protection
If a safety feature is triggered:
•The fault control lamp 4 lights up.
•all voltage conducting unit components (the heating
element) are switched off immediately i.e. the safety
circuit transfers the unit to a stable, safe condition.
The fault cause must be identified and remedied.
After the fault has been eliminated the unit can be started
again by pressing the outer ring 5a.
12.1 Excess temperature protection dial
It offers protection against dangers caused by an uncon-
trolled heating up of the heat transfer liquid above the de-
sired set temperature.
The cut-off temperature is adjusted with the excess temper-
ature setting dial 5.
Proper protection can only be guaranteed if the
cut-off point has been correctly set.
12.2 Setting the excess temperature
The cut-off point is set with the excess temperature dial 5
with a rough scale of temperature values arranged around
it. This scale, of course, can only serve as an approximate
setting means for this cut-off point. However, the cut-off point
can be determined to act exactly if the following procedure
is adhered to:
If for instance a bath liquid has a fire point of 60°C the unit
should cut off after reaching 35°C at the latest:
1First set the desired set value using keys 6(+), (–) to
exactly 35°C.
2After the SWB25 has reached this temperature, turn
the excess temperature dial 5backwards very slowly
(to the left) until the unit cuts off (acoustic signal, fault
message).
3Starting the unit after the heat transfer liquid has cooled
down somewhat.
4Then set the set temperature to the actual temperature
(< 35°C).
⇒The unit can now be used for temperatures below
35°C. As soon as 35°C is reached, it is securely
switched off.

Fault Display

13. Fault display
13.1 Sensor bath/short circuit
At faults of the measured value recognition the message
”AL-F” is shown.
⇒The display part ”AL” blinks, the heater is
switched off, the shaking process is not interfered
as long as the fault is present.
When the measured value recognition has
regenerated itself the normal operation is contin-
ued.
13.2 Motor
Motor is set on drive speed setting >0 rpm
f there is no rotation at a drive speed setting of >0 the mes-
sage ”AL-d” is shown.
⇒The display part ”AL” blinks, the heater is
switched off as long as the defect is present.
When the motor starts rotating the normal opera-
tion is continued.
13.3 Range sensor
When any parameter (preset value, RTA) is out of its scope.
Change values according to chapter 11.
Should the defects appear regularly the unit has to be sent
to the service.
