2. Safety precautions
Caution! Make sure you have fully read and understood the present Manual
before using the equipment. Please pay special attention to sections
marked by this symbol.
Caution! Hot surface! Platform surface becomes very hot during use. Always
use protective cotton gloves to install or remove samples when the
temperature is set higher than 60°C.
Attention! Magnetism! Effects of a strong magnetic field on the biological systems
have to be taken in to account. Magnetic fields can affect heart pace-
makers, data carriers, etc.
Caution! Do not use as heat transfer medium any other liquids except distilled
water.
GENERAL SAFETY
Save the unit from shocks and falling.
Store and transport the unit at ambient temperatures between -20°C and +60°C and
maximum relative humidity of 80%.
After transportation or storage and before connecting it to the electric circuit, keep the
unit under room temperature for 2-3 hrs.
Before using any cleaning or decontamination methods except those recommended
by the manufacturer, check with the manufacturer that the proposed method will not
damage the equipment.
Do not make modifications in design of the unit.
If water steams away from the bath and the heating element is higher than 100°С,
the thermostat automatically powers off. Add water to the bath only after cooling of
the heating element.
ELECTRICAL SAFETY
Connect only to the mains corresponding to that on the serial number label.
Do not plug the unit into an ungrounded power socket, and do not use an ungrounded
extension lead.
Ensure that the power plug is easily accessible during use.
Disconnect the unit from the mains before moving.
If liquid penetrates into the unit, disconnect it from the mains and have it checked by
a repair and maintenance technician.
Do not operate the unit in premises where condensation can form. Operating condi-
tions of the unit are defined in the Specifications section.
DURING OPERATION
Do not operate in environments with aggressive or explosive chemical mixtures.
Please contact manufacturer for possibility of the operation in specific atmospheres.
Do not operate the unit if it is faulty or has been installed incorrectly.
Do not use outside laboratory rooms.
Do not check the temperature by touch. Use a thermometer.
BIOLOGICAL SAFETY
The user is responsible to carry out appropriate decontamination if hazardous mate-
rial spills on or penetrates into the equipment.

3. General information
Water bath-thermostat WB-4MS is designed for chemical, pharmaceutical, medical
and biological laboratory research that require maintaining a constant temperature from +25
°C to +100 °C. WB-4MS provides increased temperature stabilization accuracy (up to 0.1°C)
due to built-in magnetic stirrer (stirring speed is regulated in 250 to 1000 rpm range). Ease
of maintenance, high temperature maintenance accuracy, compact size and innovative de-
sign of the water bath-thermostat meet the requirements of a modern laboratory.

4.3. Setup.
- Place the unit upon even horizontal stable non-flammable surface 30 cm away from
any flammable materials, and clear 20 cm around the device on all sides for ventila-
tion.
- Connect the power cable to the socket on the rear side of the unit, and position it
with easy access to the power switch and plug.
- Remove the protective film from the display.
- Place the magnetic stirring element at the bottom of the bath.
Caution! Magnetic stirring element is made for stirring distilled water for uni-
formity of the temperature.
- Place the BP-1 platform at the bottom of the bath over the heating element.
- If necessary, place optional tube racks on the BP-1 platform. Do not place more
than 2 tube racks at once.
- Fill the water bath with distilled water to cover heating element (2-3 L).
Caution! Turning the unit on when the heating element is not covered with wa-
ter is strictly prohibited.
Caution! If the protection from the overheating is activated, switch off the unit
and have unit checked by a repair and maintenance technician in ac-
cordance with the procedure specified in the Maintenance section.
5. Operation
Recommendations during operation
The water level in the bath should cover heating element. A user is responsible for
monitoring of the water level in the bath.
If water has steamed away from the bath, the unit should be switched off. Water may
be added to the bath only after cooling of the heating element.
It is recommended to cover the water bath with a lid if the temperature exceeds 50°C.
Do not fill glassware over the level they are immersed in the water to ensure best
temperature uniformity of the samples.

5.1. Connect the power cord to a grounded power socket. Switch ON the Power switch
situated on the front right lower side of the unit.
5.2. The unit will turn on and the following readouts appears on the display:
- Previously set time (fig. 1/2), set speed of magnetic stirring element (fig. 1/4) and
set temperature of water (fig. 1/6) in the upper line (Set);
- Time indication (STOP, fig. 1/1), current speed of magnetic stirring element (fig. 1/3)
and current temperature of water (fig. 1/5) in the lower line (Actual).
5.3. Settings. Press the Select key (fig. 1/7) to choose the parameter to change. Each
pressing of the Select key consecutively activates the parameters. The active param-
eter is flashing. Use the ▼ and ▲ keys (fig. 1/4) to set required value. Pressing the
key for more than 2 s will increase the increment.
5.4. Temperature setting. Activate and set the temperature (T(°C), fig. 1/6). Heating
starts. The actual temperature value appears in the lower line of the display (fig. 1/5).
5.5. Magnetic stirring element rotation speed setting. Activate and set the rotation
speed in rpm (RPM, fig. 1/4). The actual speed value appears in the lower line of the
display (fig. 1/3).
5.6. Time setting. Activate and set the desired time in hours and minutes (Time (hr:min),
fig. 1/2).
5.7. Press the Run/Stop key (fig. 1/9) to start the timer. The elapsed time interval appears
in the lower line of the display (fig. 1/1).
5.8. After the set time interval elapses, the timer gives a sound signal and the flashing
STOP indication will be shown on the display. Press the Run/Stop key once to stop
the sound signal.
Caution! Stopping the timer does not stop the heating/temperature mainte-
nance process. The heating can be stopped by reducing the temper-
ature below 25°C using the ▼ key (fig. 1/4) until the OFF indication
appears on the display.
5.9. If the working time is set to 00:00, unit operates continuously.
5.10. To stop the timer before the set time interval elapses, if required, press the Run/Stop
key. Press the Run/Stop key again, the timer starts counting previously set time.
5.11. After the thermal stabilisation of the unit, e.g. when the set and current temperature
readings become equal, open the water bath lid, place samples into the bath and
close the lid.
5.12. After finishing the operation, switch OFF the power switch. Disconnect the power cord
from electric circuit.
