Safety Instructions
• Read the operating instructions in full before starting up and
follow the safety instructions.
• Keep the operating instructions in a place where they can be
accessed by everyone.
• Ensure that only trained staff work with the appliance.
• Follow the safety instructions, guidelines, occupational health
and safety and accident prevention regulations.
• Socket must be earthed (protective ground contact).
• Before starting the device for the first time, ensure that the
connector cable is suitable for the type of socket used and
that a safe protective earth connection is assured.
• Risk of burns! Exercise caution when touching the housing
parts and the heating plate. The heating plate can reach
temperatures in excess of 100 °C. Pay attention to the residual
heat after switching off. The device may not be transported
unless it is cold!
• Don’t operate the appliance in explosive atmospheres, with
hazardous substances or under water.
• Set up the appliance in a spacious area on an even, stable,
clean, non-slip, dry and fireproof surface.
• The base plate must be clean and intact.
• The voltage stated on the type plate must correspond to the
mains voltage.
• The socket for the mains cord must be easily accessible.
• The power adapter cable must not be allowed to come into
contact with the hot mounting plate.
• Check the appliance and accessories before hand for damage
each time you use them. Do not use damaged components.
• Caution! Only media whose flashpoint lies above the safety
temperature limit of 130 °C may be processed or heated with
this device.

• Beware of hazards due to:
- Flammable materials
- Combustible media with a low boiling temperature
- Incorrect container size
- Overfilling of media
- Unsafe condition of container.
• Only process media that will not react dangerously to the extra
energy produced through processing. This also applies to any
extra energy produced in other ways, e.g. through light
irradiation.
• Bear in mind the possibility of contamination that might lead to
undesirable chemical reactions.
• Wear your personal protective equipment in accordance with
the hazard category of the media to be processed.
Otherwise there is a risk from:
- Splashing and evaporation of liquids
- Ejection of parts
- Release of toxic or combustible gases
• Do not heat liquid media except with the block. Never pour
liquid media directly on to the heating plate!
• Accessories must be securely attached to the machine and
can’t come off by themselves.
• Always disconnect the plug before fitting accessories.
• Safe operation is only guaranteed with the accessories
described in the “Accessories” chapter.
• The appliance must only be disconnected from the mains
supply by pulling out the plug-in power supply unit.
To the protection of the equipment.
- The appliance may only be opened by experts.
- Do not cover the device, even partially e.g. with metallic plates
or film. This results in overheating.
- Protect the appliance and accessories from bumps and impacts.

- Ensure that the base plate is kept clean.
- Observe the minimum distances between the devices, between
the device and the wall and above the assembly (min. 100 mm)

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).

• Temperature Setting
The temperature setting can only be workable when the
machine is powered on but not when it’s working. Short press
the blue knob; the temperature value on the LED display will
flash, and then set the temperature by horizontal rotation of
the knob.
• Time Setting
The time setting can only be workable when the machine is
powered on but not when it’s working. Short press the blue
knob twice; the time value on the LED display will flash, and
then set the time by horizontal rotation of the knob.
• Create a new program
The system can save 5 sets of programs of the temperature
and time. When the machine is powered on but not when
working, short press the button of “Prog.” to select the 5
default programs from P1 to P5. For example, if select P2,
press and rotate horizontally the blue knob to set the new
temperature and time as the method described as above.
Long press “Prog.” continuously to save the new data as P2..
• Program for quick operation
When the machine is powered on but not when working, short
press “Prog.” to select the required program for quick operation.
The program data can be changed by the blue knob

Temperature Calibration
Each single instrument is calibrated before shipment. If there is
deviation between the actual temperature and the displayed
temperature for some reasons, you can do as follow to calibrate
the unit again.
1. Long press the blue knob for more than 3 seconds and the
system will be in the calibration mode. When the machine is
ready for calibration, there’s only temperature on the display
and no time.
2. Press “Prog.” to select the calibration point of 40°C / 60°C /
80°C / 100°C (If they’re not the four calibration points in the
program, set the required temperature by rotating the blue
knob). Or directly rotate the blue knob to the appointed
calibration points instead of pressing “Prog.”
3. Put high boiling point solution (above 100°C, for example:
glycerin) into the block hole and then place a thermometer
into the hole. (Make sure the accuracy of the thermometer
should be within 0.1°C and the thermometer probe should be
absolutely immersed into the solution). And make sure to put
the thermometer into the hole which is in the middle of the
block or closed the middle hole.
4. Press the “Run/Stop” and the system will be in “Heating” mode.
5. After about 20 minutes of the “Holding” mode, read the data
from the thermometer and press “Run/Stop”. Adjust the
temperature of the machine by rotating the blue knob per the
reading of the thermometer.
6. Long press “Prog” to save the reading of the thermometer.
7. Repeat the above processes to do the calibration of other
calibration points. Refer to the below Table.
