Set up the instrument in a spacious are on a stable, clean, non-slip, dry and fireproof surface. Do not operate the instrument in explosive atmospheres, with hazardous substances or under water.

Gradually increase the speed, reduce the speed if:

- Stirring bar breaks away due to high speed

- The instrument is not running smoothly, or container moves on the base plate

Temperature must always be set at least 50 °C lower than the fire point of the media used.

Be aware of hazards due to:

- Flammable materials or media with a low boiling temperature

- Overfilling of media

- Unsafe container

Process pathogenic materials only in closed vessels.

Check the instrument and accessories prior to each use. Do not use damaged components. Safe operation is only guaranteed with the accessories described in the "Accessories " chapter. Accessories must be securely attached to the device and can not come off by themselves. Always disconnect the plug before fitting accessories.

When the external temperature sensor needed, the tip of the measuring sensor must be at least 5-10 mm from vessel bottom and wall.

The instrument can only be disconnected from the main power supply by pulling out the main or the connector plug.

The voltage stated on the label must correspond to the main power supply.

Ensure that the main power supply cable does not touch the hotplate. Do not cover the device.

The instrument may only be opened by experts.

Keep away from high magnetic field.

Do not use this instrument in an explosive environment; This instrument has no explosion-proof function.

2. Proper use

The instrument is designed for mixing and/or heating liquids in schools, laboratories or factories.

Observe the minimum distances between the devices, between the device and the wall and above the assembly (min. 100 mm)

Figure 1

This device is not suitable for using in residential areas or other constraints mentioned in Chapter 1.

5. Trial run

Make sure the required operating voltage and power supply voltage match.

Ensure the socket must be properly grounded.

Plug in the power cable ,ensure the power is on and begin initializing.

Add the medium into the vessel with an appropriate stirring bar.

Place vessel on the work plate.

Set the target stirring speed and begin.

Observe the stirring bar and LED display (digital model).

Set the target temperature and start heating.

Observe the LED display (digital hotplate model).

Stop the heating and stirring functions.

If these operations above are normal, the device is ready to operate. If not, the device may be damaged during transportation, please contact manufacturer/supplier for technical support.

Warning!

Forbid to transfer the vessel when the instrument working.

6. Function: Heating (Digital hotplate model)

The device is controlled by digital temperature control technology, which has two separate safe circuits. The hotplate is kept at a constant

temperature by a digital control circuit. The hotplate temperature can also be monitored from a separate, adjustable safe circuit. The two

temperature sensors internal for temperature control are built into the hotplate. The single external PT1000 can monitor the temperature of sample.

Plug in the external PT1000.

Set the temperature via rotating the temperature control knob slowly to the target value.

When the heating function is switched on, the LED displays the temperature value on the left-hand side.

The heating function is switched on or off by pushing heating knob. The instrument automatically displays the last running speed an temperature parameters once turned on.

Generally, the LED screen cannot display the actual temperature of sample in the vessel or hotplate surface, temperature differences as following:

- Hotplate center and outer edge.

- The sample in the vessel and hotplate surface.

In order to ensure the accuracy of the temperature inside the container, please use the external temperature sensor PT1000.

6.1 Working with external temperature sensor

Figure 8

The external temperature sensor PT1000 is the manufacturer ' s standard accessory. When PT1000 sensor is connected and rotate the temperature control knob, LED displays the temperature setting value and shifts to real value in 5 seconds. Safe circuit controls hotplate temperature under 320 ° C. Comparing with the temperature control of the hotplate, the external temperature sensor can control the medium 's temperature more precise. The heating function will be stopped automatically under abnormal conditions. Please operate follow the instructions below:

l Switch OFF the instrument.

l Ensure the external temperature sensor is inserted in the media heated.

l Switch ON the instrument and run heating function.

If the heating function does not work, please contact manufacturer/supplier for technical support.

6.2 Residual heat warning(HOT)

In order to prevent the risk of burns from a hotplate, digital hotplate has a residual heat warning function. When the heating function is switched off and the heating plate temperature is still above 50 °C, "Hot" will flash to warn that there is a hazard of burns from the hotplate. When the unit is powered off, the LED screen displays the temperature of hotplate and Hot in turn. When the hotplate temperature drops to below 50 ° C, the unit will automatically switch off. If users want to turn off the LED immediately, just pull out the plug directly. When the plug is pulled out, the residual heat warning function cannot be run.

7. Stirring

The function "stirring" of LED digital model is switched on or off via pushing on/off speed control knob. The speed range of 200 to 1500 rpm and in steps of 10 rpm.

The function "stirring" of classic model is switched on or off via rotating speed control knob. The speed range of 200 to 1500 rpm.

8. Faults

Instruments can 't be power ON

- Check whether the power line is unplugged

- Check whether the fuse is broken or loose

Fault in power ON self test

- Switch OFF the unit, then switch ON and reset the instruments to factory default setting.

Stir speed cannot reach set point

- Excessive medium viscosity may cause abnormal speed reduction of the motor

Unit cannot be powered off when switched off.

- Check if the residual heat warning function is still ON and hotplate temperature is above 50 °C (the LED screen still work and " Hot " flash).

If these faults are not resolved, please contact dealer/ suppler.

9. Maintenance and Cleaning

Proper maintenance can keep instruments working properly and lengthen its lifetime.

Do not spray cleanser into the instrument when cleaning.

Unplug the power line when cleaning.

Only use recommended cleansers:

Dyes	Isopropyl alcohol
Construction materials	Water containing tenside /Isopropyl alcohol
Cosmetics	Water containing tenside /Isopropyl alcohol
