2. THE JULABO QUALITY MANAGEMENT SYSTEM
Development, production and distribution of temperature application
instruments for research and industries conform to the requirements
according to DIN EN ISO 9001:1994-08.
Certificate Registration No. QA 051004008.
3. DESCRIPTION
JULABO shaking water baths of the series SW22 and SW23 are ideally suited for
laboratory applications and research in the fields biology, biochemistry, pharma-
cology, chemistry and general medical technologies. They are likewise suited for
routine laboratory tasks and long-term unattended operation. The JULOBO shaking
water bath SW 23 with constant bath liquid circulation, ensures a constant water
temperature with a maximum deviation of ±0.02 °C .
Julabo shaking water baths feature a stainless steel bath containing heater,
temperature sensor and the overtemperature protection safety element. The shaking
carriage is totally removable.
The units are operated via a water protected foil keypad with integrated mains
switch. Microprocessor technology enables selection and storage of different
temperature values and operating times, and display of them in the LED-
MULTI-DISPLAY. The self-optimizing electronic PID-control circuit
automatically adjusts the heat supply to the value required by the bath.
The RS232C port permits modern process engineering without additional
interface, directly on-line, from the waterbath to your application equipment.
The overtemperature protection to DIN 12876-1: 2000 is a safety feature with a
fixed safety value of 130 °C. It functions independent of the regulator circuit.
The waterbaths conforms to the safety requirements specified by
DIN 12876-1: 2000 (class 1), as well as DIN 12876-2: 1999/12, the guideline for first
voltage range EN 61010.
FThe safety classification 1 permits unattended operation
with non-flammable bath liquids!
4. UNPACKING AND CHECKING
Unpack the shaking water bath and accessories and check for damages incurred
during transit. These should be reported to the responsible carrier, railway, or postal
authority, and a request for a damage report should be made. These instructions
must be followed fully for us to guarantee our full support of your claim for
protecting against loss from concealed damage. The form required for filing such a
claim will be provided by the carrier.

5. PREPARATIONS
5.1. Installation
>80 mm
The installation site should meet the following
conditions:
1. The base of the installation site should be level to
ensure proper functioning of the safety features.
2. The laboratory table, for example, should be
sturdy enough, to where the shaking frequency
cannot cause vibration of the table. Consider that
the masses moved may be in the order of several
kg.
At unattended operation, the vibration may
cause items on the table top to fall off under
extreme unfavorable circumstances.
3. Keep a wall distance of minimum 80 mm.
5.2. Bath liquid •Recommended bath liquid: Water
Do not use flammable bath liquids!
No liability for use of other bath liquids!
The temperature controlling i.e. immersing of test tubes,
Erlenmeyer flasks or similar objects directly within the circulator
constitutes normal circulator practise.
We do not know which substances are contained within these
vessels. Many substances are:
•inflammable, easily ignited or explosive
•hazardous to health
•environmentally unsafe
i.e.:dangerous
You alone are responsible for the handling of these substances!

5.3. Filling / Draining
Filling:
•Maximum filling level: 6 cm below the bath rim
•Minimum filling level: 7 cm (level approx. 3 cm
above surface (16) for the placement of
items/fixtures)
Note:
The working filling level depends on size and number
of the items (fixtures) to be placed inside.
Fill to minimum level only. Insert the complemented
shaking carriage and correct the filling level (adding or
removing liquid) as required.
Draining:
•Switch off the shaking water bath with the mains
switch and move the equipment to the table edge.
•Place a suitable collecting bucket or tub underneath
the equipment for draining the used liquid.
•To drain the liquid open the dainage screw (11) on
the side of the water bath.
•After the liquid has been fully drained, securely
tighten the drainage screw (11) again.
Exercise CAUTION when emptying hot bath liquids!
Recommendation:
Use the water bath cover to keep temperature losses
to a minimum. This is especially important for working
temperatures above 70 °C.

5.4. Maintaining a constant water level / Countercooling
For cooling tasks near the ambient air temperature the
liquid level/cooling set can be used for
countercooling.
By special pipe routing, cool faucet water is
continuously supplied to the water bath, while at the
same time, the heated water is drained via the overflow
connection of the Level/Cooling set.
A specific water flow rate of 100 ml/minute is
sufficient to compensate for the characteristic
temperature.
Use of the liquid level/cooling set for a continuous
supply of faucet water:
1. to keep the water level constant, especially for
applications up to the boiling point (supply of
faucet water only in the amount of evaporation
losses).
2. for countercooling of cooling tasks near the
ambient surrounding temperature (cool faucet water
is continuously supplied to the water bath, while at
the same time, the heated water is drained via the
overflow connection of the liquid level/cooling set).

6. OPERATING PROCEDURES
6.1. Power connection
Connect the unit only to a grounded mains power socket!
We disclaim all liability for damage caused by incorrect line
voltages!
Check to make sure that the line voltage matches the
supply voltage specified on the identification plate.
Deviations of ±10 % are permissible.
7. SWITCHING ON
•Switching on:
Turn on the mains power switch.
The unit performs a self-test. All segments of the 4-digit
MULTI-DISPLAY (LED) and all indicator lights will
illuminate.
Then the software version (example: n 0.0) appears.
Together with the display of the water bath temperature
the operating state is also displayed.
(Example: 18.6 °C)
The monitor lamp illuminates when the heater is in
operation (on).
Notes:
•Adjustable parameters and temperature values are
retained and the electronic timer is reset to zero when the
equipment is switched off.
•When the shaking water bath is operating under remote
control at the time of switchoff (connected to PC via
RS-232 interface connection), the MULTI-DISPLAY
(LED) will display the message „OFF“.
(see chapter 8.5. Setup for remote control
•If shaking operation is not desired it can be switched off
at menu level. Select the menu level and activate the
option SA (see page 16)

7.1. Setting the temperature
Display and adjustment of the working temperature:
•Press the setpoint key .
The indicator light blinks and the value previously set
appears on the MULTI-DISPLAY (LED).
(example: 25.0 °C).
If no further key is pressed the display will return to show
the actual bath temperature after approx. 8 seconds.
‚Use the cursor keys to move left or right on
the display until the numeral you wish to change is
blinking.
ƒUse the increase/decrease arrows to change
the selected numeral (0, 1, 2, 3, ... 9).
„Press enter to store the selected value
(example: 38.0 °C).
The working temperature is maintained constant after a
short heat-up time (e. g. 38.0 °C).
When the working temperature is higher than 90 °C, it might happen
that due to strong production of steam there is considerable dripping
on the inside of the lift-up Makroloncover. Some drops may fall
directly into the material to be tempered.
7.2. Warning functions or temperature limit
%)..)..)..)
More protection for your samples in the bath!
As soon as the actual temperature leaves one of the pre-
adjusted limits, this status is evaluated.
The high- and low-temperature limit can be evaluated in two
ways (see page 21).
1. As pure warning function with an acoustic signal in
regular intervals. (Signal - Pause)
(DBGM: G94 10 134.5)
2. As temperature limit by switching-off the heating and
alarm.
