1. SAFETY INSTRUCTIONS
Read the operating instructions in full before starting up and
follow the safety instructions.
• Socket must be earthed (protective ground contact) before use.
• Water must be filled into the chamber before power-on.
• Avoid operating the bath without water.
• The symbols below are marked on the equipment and in this
manual to indicate:
Caution: Surfaces can be hot during and after use
Caution: Socket must be earthed
(protective ground contact).
2. UNPACKING
Please unpack the device carefully and check it for damage. It
is important that any transport damage is detected when the
device is unpacked. If necessary, any inventory of the damage
should be made immediately (postal service, railway, haulage
company).

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.
2. The lid should only be lifted by the handle, as other parts can
become hot during use.
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.
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.

5.4. Configuring and running temperature presets
The bath has 3 presets: . Temperature presets allow
you to conveniently store or run bath temperature settings for you
routinely use.
Before you can use presets, you need to store the values you wish
to use in at least one of the presets as the following procedures:
For example:
configuring the preset P1, the current temperature is 37.0°C, preset
the temperature 50.°C
Running the preset as the following procedures
For example: run the preset P1
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;
Press the over-temperature alarm key to
enter the setting menu.
Set the over-temperature alarm limit you
require
Press the over-temperature alarm key again
to save the setting, it displays the current
temperature/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 1~999 min
After the countdown is over, an alarm will sound three times and
the heating will stop, “OFF” is displayed.
Note:
1. When the countdown time is more than 10 minutes, the countdown
time is hidden and the real-time temperature is displayed.
2. When the countdown time is less than 10 minutes, the countdown
time is displayed.
3. The countdown can start only in heating state. The countdown
will stop once the heating is stopped.
4. In heating state, save the setting value of timer, the countdown
will start immediately.
5. In unheated state, save the setting value of timer, then press the
“Run/Stop” to start countdown.
6. 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 10 min.

5.8. Setting the dry-start protection alarm
When the dry-start protection function is on, the bath will stop
heating and an alarm will sound when the system detects that the
inner chamber is in dry-start status. When the dry-start protection
is off, there is no protection alarm and the bath will continue
heating to the set temperature.
For example:
the current temperature is 37.0°C, set the dry-start protection from
“ON” to “OFF”;
6. CALIBRATION
6.1. Calibration condition
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.

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: 30 ~ 40°C
High temperature point: Above 55°C
Low temperature point calibration:
For example:
Before calibration, the screen displays 32.0 C but the actual liquid
temperature is 37.0°C
After calibration, the screen displays 36.8 C and the actual liquid
temperature is 37.0°C
High temperature point calibration:
For example:
Before calibration, the screen displays 60°C but the actual liquid
temperature is 65.0°C;
After calibration, the screen displays 64.7°C and the actual liquid
temperature is 65.0°C;
Select the menu option
Select the low temperature point calibration
setting menu option
Press set to enter the calibration value
Enter the reference thermometer value
Press to store the calibration value
The setting will exit automatically after 5S
without operation
Leave the bath to stabilize and check the
calibration
