SAFETY PRECAUTIONS

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

• Do not place any steel or magnetic material on the base plate except the recommended magnetic stirring bar with a vessel or flask in between. Doing is can affect the magnetism of the device.
• Place the device on a flat, stable, clean, non-slippery and fire-proof surface.
• The base plate must be clean and intact.
• Do not try to mix liquid more than 200 liters with 80 mm magnetic stirring bar on a single stirring position. It may lead to improper mixing.
• Wear protective equipment in accordance with the hazardous category of the media to be processed. Otherwise, there is a risk from:
• CF Splashing and evaporation of liquids.
• CF Ejection of parts.
• CF Release of toxic or combustible gases.
• Do not lift or hold the device from the power cable.
• Do not use a damaged beaker, flask, stirring bar 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.
• Wear protective gloves while cleaning the device.
• Do not touch the base plate immediately after the operation. The base & plate may get warm after continuous usage.
• 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 produced use liquid through for mixing processing. that will not This react also applies dangerously to to any the extra extra energy 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.
• Chemical reaction of PTFE can occur when in contact with molten or dissolved alkaline earth metals, as well as with fine powders of metals from the 2nd or 3rd group of the periodic table at temperatures above 300-400 °C. Only elementary fluorine, chlorine trifluoride, and alkaline metals attack PTFE. Halogen hydrocarbons have a reversible swelling effect.
• The temperature of the stirring media in the beaker and beaker itself should not be more than 45° C.
• The equipment will not restart, both in case of power interruption and in fe\
• Care should be taken based on the sample used for mixing.

ACCESSORIES

• Magnetic Stirring Bar
• Power Adapter: 100-240VAC 50/60Hz (Input), 24V :-:: l.SA (Output)

INSTALLATION

Gently take the unit out of the box and place it on a flat, stable and nonslippery surface. Keep 1-inches clearance from all 3 sides of structure frame so that it can be operated easily and safely. Do not lift the instrument by holding the platform. Plug in the power adapter pin before connecting to the power source. The instruction manual and accessories should be kept near the device in a safe storage location for at least 2 years for warranty purposes.
Below image & table shows the function of user interface buttons:

USER INTERFACE AND DISPLAY

OPERATION

• Connect the AC power adaptor to the main power supply.
• Fill the beaker or vessel with the medium or liquids to be processed. Then Place the magnetic stirring bar at centre of beaker or vessel.
• Place the vessel or beaker on the center of the base plate.
• Set the speed at which the medium or liquids need to be processed. Minimum speed is 100 RPM and maximum speed is 600/800/1000 RPM.
• Set the time if required. Minimum time is 1 minute & maximum time is 99 hours & 59 minutes & infinite mode.
• Turn on the stirrer by pressing ON/OFF button.

SPEED/ SLIP SETTING

• Single press to enter speed, Speed can be adjusted by ‘+’ & ‘-‘ button from 100 RPM to 1000 RPM.
• Single press the increment or decrement button to increase or decrease the value by 10RPM on each press.
• Speed value is saved after 5 blink in display.
• Long press the ‘SPEED/SLIP’ to activate the slip detection mode and “Slip On ” Status shown on display.
