3. INSTALLATION
3.1 Assembly of the equipment and components
The water bath has three main components, the bath, the lid
and the base tray. The base tray fits into the bath with the feet
downward so that it creates a gap between the bottom of the
chamber and the tray.
Note:
1. For optimum temperature stability, avoid allowing the base
tray and sample container to touch the sides of the chamber
while operating.

5
2. The lid should only be lifted by the handle, as other parts can
become hot during use.
3. It has a vent/thermometer hole–this hole should not be
sealed as pressure could build up inside the bath.
3.2 Instrument placement
Place the water bath on a level, non-combustible surface.
Ensure that the mains plug and the switch are easily accessible.
3.3 Electrical supply
• Check that the supply voltage marked on the serial number
label, and the type of mains plug, are correct for your mains
supply outlet, which must have a ground connection.
• To disconnect the equipment from the mains supply, remove
the mains plug from the mains supply outlet.
4. CORRECT USE
4.1. Avoid operating the bath without water
• Avoid using your bath without water in the chamber. Dry-start
will affect the service life of the key component.
• The bath has an inbuilt protection mechanism known as dry
start protection which will detect this condition in most
circumstances and prevent the bath from continuing to heat.
In this instance the bath will display “ ” and sound an
alarm. If theprotection program fails to detect the dry-heating,
built-in safety temperature cut-out switch will cut off the heating
to protect the water bath when heated to a certain temperature .
Note:
The dry-start protection program is on by default. If you need to
turn it off, please refer to 5.8. Setting the dry-start protection alarm.
The chamber internal surface can become very hot if an
accidental dry start has occurred, even if the dry start cut out
has operated. Avoid touching the chamber until it has been left
to cool.

4.2. Emptying the baths
Before emptying any bath, disconnect the device from the power
supply and pull out the plug. Then allow the water temperature
to fall to a safe level and take reasonable precautions to prevent
accidental spillage.
The drainage operation is as follows：
1. Insert the drain pipe into the drain port according to the
direction shown in the figure.
① Drain pipe
② Drain port
2. After draining, loosen the lock of the drain port in the direction
of the arrow as shown in the figure, and then quickly pull out
the drain pipe.

4.3. Using transparent lid
• When the setting temperature is above 60°C , use the lid to
maintain proper temperature control and ensure that the water
temperature reaches the set point.
• The lid will also prevent excessive evaporation that requires
the bath to be filled more often and will save energy.
4.4. Using base tray
• Using the base tray can improve temperature control inside
containers.
• Don’t put the containers or other items into the stainless-steel
chamber directly. Avoid the containers or other items direct
contact with the inside walls of chamber.

5.5. Switch between Fahrenheit Temperature (°F) and Celsius
Temperature (°C)
When the °C indicator is on, the unit of temperature is °C; When
the °F indicator is on, the unit of temperature is °F.
Setting procedures as following:
For example: switch “°C” to “°F”.
5.6 Setting the over temperature alarm
Protect the sample by setting the max. temperature that the bath
allows to be heated.
The setting procedures are as following:
For example:
the current temperature is 37.0°C and the over-temperature alarm
limit is 90.0°C

If the liquid temperature exceeds the setting over-temperature alarm
limited temperature, the water bath will stop heating, display “ ”
and start an alarm. The alarm can be turned off by the following
operations:
• Turn off the power, the alarm is turned off, and restart the machine
after the water temperature is lower than the over-temperature
alarm limited temperature ;
• Add some cold water until the water temperature drops below the
over-temperature alarm limited temperature, and the alarm will be
turned off;
• Set the over-temperature alarm limited temperature to above the
water temperature, and the alarm will be turned off.
5.7. Setting the countdown timer
The countdown timer range is 0~99H59min.
After the countdown is over, an alarm will sound three times and
the heating will stop, “OFF” is displayed.
Note:
1. The countdown can start only in heating state. The countdown will
stop once the heating is stopped.
2. In heating state, save the setting value of timer, the countdown
will start immediately.
3. In unheated state, save the setting value of timer, then press the
“Run/Stop” to start countdown.
4. The countdown settings are independent of the temperature
settings. When setting the countdown, take into account the
time required to achieve the set temperature.
The countdown timer setting as following procedures:
For example:
set the countdown time from 0 to 1 hour 10 minutes.

5.8. Setting the dry-start protection alarm
When the device is started, the dry-burning protection function
is automatically turned on.
When the system detects that the inner pot is in a dry state, it
will stop heating and sound analarm.
6. CALIBRATION
6.1. Calibration condition
To ensure accurate calibration results, good calibration conditions
are required:
1. The accuracy of the thermometer should be more than 10 times
that of the water bath display.
2. At a stable ambient temperature (+/-1°C) without air convection.
3. Wait for the liquid to reach the calibration setting temperature
and stabilize for 30 minutes before calibrating.
4. Add water to the water bath to 50 mm above the tray, and place
the thermometer in the center of the water bath, 40 mm away
from the tray.

6.2. Dual point calibration
Due to the influence of ambient temperature, humidity, and pot
structure, the water bath has a certain deviation in temperature
measurement. In order to improve the measurement and control
accuracy, each single instrument is calibrated before shipment.
Includes two calibration options -- low temperature point and high
temperature point.
Low temperature point(LCP): 40°C
High temperature point(HCP): 95°C
Low temperature point calibration:
For example:
Before calibration, the screen displays 40.0 C but the actual liquid
temperature is 42.0°C
After calibration, the screen displays 41.8 C and the actual liquid
temperature is 42.0°C
High temperature point calibration:
For example:
Before calibration, the screen displays 95°C but the actual liquid
temperature is 98.0°C;
After calibration, the screen displays 97.7°C and the actual liquid
temperature is 98.0°C;
Operation Display
