SAFETY PRECAUTION

Read the following safety instruction before using this overhead stirrer for your safety & the safety of the equipment.

• The users must make ensure that the OFF switch of the device can be accessed immediately, directly and without risk at any time all the time.

• Ensure stable assembly. The vessel used for stirring must be secured.

• Remove the chuck key from the chuck before turning the device on.

• Imbalance of the output shaft, the chuck and in particular the stirring tools can lead to uncontrolled resonant vibrational behaviour of the device and the whole assembly. Thus make ensure all the components are fasten properly.

• Never operate the device with the stirrer tools rotating freely. Ensure that parts of the body, hair, jewellery or items of clothing cannot be trapped by the rotating parts.

• The safety of the user cannot be guaranteed if the device:
  operated with accessories that are not supplied or recommended by the manufacturer.
  operated improperly or contrary to the manufacture’s specifications.
  **** the printed circuit board are modified by third parties.

• Do not place any solid particles during motion of the impeller. Use sufficient large container, beaker or flask to avoid spillage.

• Place the device on a flat, stable, clean, non-slippery and fire-proof surface.

• Do not try to mix liquid more then recommended volume of liquid (H20 at room temperature).

• Wear protective equipment in accordance with the hazardous 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 lift or hold the device from the power cable.

• Do not use a damaged beaker, flask, chuck/collet or any other component for operation. It may affect the efficiency of the device.

• Reduce the speed:
  If the medium splashes out of the vessel.
  If the appliance is not running smoothly.
  **** If the container moves on the base plate.

• Do not touch the impeller, rotating shaft, stirring liquid extra

• Process pathogenic materials only in a closed vessel under a suitable extractor hood. Do not operate the appliance in explosive atmospheres, with hazardous substances or under water.

• Only use liquid for mixing that will not react dangerously to the extra energy produced through processing. This also applies to any extra energy produced in other ways. Examples included: through light irradiation, through surrounding temperature etc.

• Abrasion of the dispersion equipment or the rotating accessories can get into the medium you are working on.

• The equipment will not restart, both in case of power interruption and in the case of any fault or mechanical interruption.

• Care should be taken based on the sample used for mixing.

INSTALLATION & OPERATION

Open the box, unpack the device & place the device on a level surface gently. Then unpack the accessories & assemble them as instructed below. Keep all the boxes in safe storage at least for 2(two) years to claim any warranty services. The user manual always should be kept with the instrument for quick reference.
Assembly
Ensure that the extension arm is fitted securely. Vibration may cause the screw to become loose. It is therefore necessary for safe use to regularly check that the extension arm is attached securely. Tighten the hexangular bolt as required.
Check that the stirrer is held in position firmly prior to each use and also at regular intervals. The position of the stirrer must only be adjusted when the equipment is stationary and the power supply is disconnected.

3| | Press timer key, to set the value between lmin – 99hrs S9mins or continuous mode.
4| | Press once to have an increments of 1. Press and hold to increase the value faster.
5| | Press once to have a decrements by 1. Press and hold to decrease the value faster.
6| | Press to select the impeller direction in CW or CCW
7| | This mode enables user to set auto resume operations from the left time upon re-storage of power if there is any failure, rather then reset of the parameters & restart all the operation from the beginning.
8| | This mode enable stirring of the sample even upon change in viscosity of the liquid.

Function(All the keys will be operational only upon turning the power switch)
Start/Stop:
Press the key to start the mixing. To stop the operation press the same key again.
RPM:
To set speed in rpm, press the key upon blinking desired rpm can be set in chosen direction. Change the value by using +/- key or Knob.
Timer:
Press time key, to set the value between lmin – 99hrs 59mins or continuous mode. Press and hold time to select infinity/continuous mode. The infinite mode will be indicated in ” ”
Increment:
To increase the value, press once to have an increments of 1. Press and hold to increase the value faster. This key is used for adding the values in the parameters such as Speed & timer.
Decrement:
To decrease the value, press once to have a decrements by 1. Press and hold to decrease the value faster. This key is used for reducing the values in the parameters such as Speed & timer.
CW / CCW:
Press the button once to select the direction in clockwise & again to switch to counter clockwise (Anti clockwise) which will be indicated by LED near display.
Power Intermittent Mode:
This mode enables user to set auto resume operations from the left time upon re-storage of power if there is any failure, rather then reset of the parameters & restart all the operation from the beginning.
By Default this mode is off. Press Once to Activate the Mode, will be indicated by LED. Once the mode is turned on, at power failure the machine will remember the last running value save after completing the next 5mins. and the device will resume the operation for the left time only upon the power is restored. Example: If 60 minute is the set time and the power off happens at 54 or 51minutes, the machine will resume from 55minutes; and if power off happens at 58minutes then it resumes at 60min.
Smart Control:

• Smart Control OFF: By default standard over load protection control is active in the device. The actual speed of stirrer shaft will be reduced to zero and device will stop with an Error OL if the device detects the overload in torque then recommended (Refer to specification table & error codes at the end).
• Smart Control ON : Switch on the device and press the smart control button, if the torque value is higher than recommended, the device automatically detects & reduces the motor speed until it find optimum speed for constant mixing even at higher torque. Eg: the set rpm say 1000 is higher for mixing the solution, than the speed will be reduced until it find optimum speed for constant mixing. This speed reduction will take place until the safe speed reached at which the torque value is normal. If it is 750rpm then the device with set 750rpm as new speed & continues to stir. This also will avoid any overload on the machine. Incase the machine still detects beyond the torque required for mixing then the machine will shut itself down because of overload (OL error).

Knob/Encoder:
Turn the knob CW for increment & CCW for decrement of time & speed parameters

MAINTENANCE & CLEANING

• Plug off the Machine while cleaning
• Do not spray cleanser into the instrument when cleaning
• Wear protective gloves while cleaning the machine
• Cleaning should be done with Mild detergent and water
• Wipe the exterior of machine with a Damp cloth
• Always clean the impeller after every use for better operation. 10.

TROUBLESHOOTING

cable at both ends.
Power failure| Check the mains fuse of the lab.
Improper connection.| Connect adaptor properly.
OL (Overload)| Require torque to mix the medium at given speed is more then the rated value of the device.| Switch of the device completely. Unplug the power adaptor. This will reset the error. Decrease the load on the motor and restart device again
OT (Over Temperature)| Motor temperature is too high| Switch of the device & allow it cool down
Er 52| No motor feedback| Contact service center or supplier
■| Product vibrates too munch & excessive noise durring operation| Check the impeller, bend or damaged impeller may cause vibrations
Motor might be causing noise due to damage impeller.
Make adjustments to correct the conditions causing the excessive vibration
Set wrong parameter like speed & higher viscosity for the selected impeller
