SAFETY INSTRUCTIONS

In order to use this equipment properly & safely every user must read the user manual & observe safety instructions.

Do not place any steel or magnetic material on the top surface except beaker or flask with the recommended magnetic stirring bar. Doing this can affect the magnetism of device.
Place the device on a flat, stable, clean, non-slippery and fire-proof surface.
The top surface must be clean and intact. Use a soft mild cloth to clean.
Do not try to stir liquid more that 400 ml with 25 mm magnetic stirring bar per stirring position. It may lead to improper mixing.
Wear your personal 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.
The release of toxic or combustible gases.
Properly lift the device with both hands from the base while shifting or installing at other location.
Do not use damaged beaker, flask, stirring bar or any other component for operation. It may affect the efficiency of device.
Reducethespeed:
If the medium splashes out of the vessel because to high speed.
If the appliance is not running smoothly.
If the container moves on the base plate.
Wear protective gloves while cleaning the device.
The top surface will be hot after any heating operation. Do not touch the top LL surface till the hot LED indication glows.
Process pathogenic materials only in a closed vessel under a suitable extractor hood. Do not operate the appliance in explosive atmospheres, with the hazardous substance or under water.
Only use such liquids for mixing which will not react dangerously to the extra LL energy produced through heating & stirring. This also applies to any extra • energy produced through external sources. For example: 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 chemical reaction of PTFE can occur when in contact with molten or dissolved alkaline earth metals, as well as with fine partied powders of metals of the 2 and 3 group of the periodical system at temperatures above 300-400 •c. Only elementary fluorine, chlorine trifluoride and alkaline metals do attack PTFE, halogen hydrocarbons have a reversible swelling effect.
In case of power failure or mechanical interruption, stirrer will not start automatically after the restoration of power or mechanical parts. Due care should betaken.
**** Process and heat only that media which has a flash point upto 150°C.

INSTALLATION

Ideal ambient temperature is 20°C ± S°C; avoid placing the unit in direct sunlight.
Keep clearance of at least 20 cm from all side to guarantee the cooling efficiency.
Keep away from heat or water to avoid sample temperature issues.
Do not place the stirrer in a place where it becomes difficult to operate the device.

CONNECTING POWER CORD

Connect one end of the power cord to the rear side of stirrer and another end to
supply socket as shown in the figure below.
Push the power cord firmly for proper connection.

TIPS FOR EFFICIENT OPERATION

Use flat, chemical resistant and heat-resistant vessels made up of glass. The vessels should have a thin, even wall thickness. Flat glass bottoms (without any curve on the inside) and smooth surfaces will improve the efficiency of the magnetic stirring bar. Uneven surfaces would reduce the stirring power and would reduce the efficiency of stirring.

Place one magnetic stir bar in each stirring flask. Place the flasks with stir bar right in the center of the stirring point on the respective bore of the Stirring platform. This will ensure the optimum stirring effect!

In case the magnetic stir bar is not at the center or sets away from the center during the operation, check the flasks/beaker positions and move the flasks/beakers slightly to & fro around the center and place the flasks/beakers on the platform surface such that the magnetic stir bar resumes its normal stirring motion.

If the above-mentioned procedure doesn’t work, reduce the speed or amount of sample liquid in the flasks/beakers in case the bar does not stir.

OPERATION

Switch on the Stirrer

After connecting the power cord, switch ON the mains and switch ON the stirrer from
rear side as shown in above image.

Setting Time & Speed

The time in the display is in minutes. The stirrer timer set for operation is in between lmin to 999mins and infinite time mode. Infinite time is seen as”] [ “. Press “Time” to select time value and press “+ / – ” to set time. When time button is pressed, the “Mins” display will blink indicating the time value is selected. Once time value is selected, single press”+/-” will increase or decrease time value by lmin.

Long press increment or decrement button to quickly increase or decrease time value. Time value gets saved after 5 blinks. The timer is a countdown timer showing remaining time left. Once time is over, the stirrer stops. Speed is displayed as RPM.

The minimum and maximum speed of stirrer is 300 RPM and 1500 RPM respectively. When the equipment is used for the 1st time, the speed will be set to zero and shown as □□□□”. Once speed value is selected, single press “+/-” will increase or decrease speed value by 10 RPM. Long press”+/-” to quickly increase or decrease speed value. Speed value gets saved after 5 blinks.

Setting Temperature

Initially, on every startup, the temperature function will be in OFF state. To set Temperature, Single press “Temp” button to select Temperature value and then press “+/-” to set temperature value. Once the temperature is set, display will glow indicating the SETTemperature.

Temperature value can be set from Ambient temperature to 120°C. Once Temperature value is selected, pressing”+/-” will increase or decrease temperature value by 1 •c. Long press”+/-” to quickly increase or decrease the temperature value. Temperature value gets saved after 5 blinks.

To see the actual temperature value, again single press the Temp button and the ACT.
LED will glow indicating the value displayed is current Actual Temperature. By default,
the actual temperature value will be room temperature.

NOTE:

Process and heat only those media that has a flash point up to 150°C.
Be extra cautious when touching the heating stirrer platform. The heating stirrer platform can reach up to 125°C.

Pulse Mode Operation

Press “Pulse” to start pulse mode operation. In pulse mode, the stirring direction will change between clockwise and counter-clockwise direction for every 30 seconds which can be set from 30 to 99 seconds. Upon the selection of “PULSE”, pulse button will glow. Again press the “Pulse” button to STOP pulse operation.

Programmable Pulse Mode Operation

By default, the pulse mode cycle time is 30 seconds (i.e. 30 seconds clockwise and 30 seconds anti-clockwise). With programmable pulse mode, the user can modify cycle time from 30 secs to 99 secs. Long press the pulse button to select pulse mode cycle time. The time display will change to “s 30” where “3 □” means pulse cycle time in seconds – this indicates that user can now modify pulse cycle time. Then press increment or decrement button to modify cycle time between 30 secs to 99 secs.

Start & Stop Operation

Once all the parameters like Speed, Time & Temperature are set, press “Start/Stop” button once to START operation. Once operation starts, the LED adjacent to “Start/Stop” will glow. To STOP operation, again press the “Start/Stop” button. LED adjacent to the button will stop glowing indicatingthatthe operation is stopped.

Make sure that stirring operation is started only after flask/beaker is placed on the surface. Placing the beaker/flask in between any operation can lead to improper stirring or no stirring at all.

NOTE: Proper stirring is achieved only if beaker/flask is placed before any run operation or only if speed is increased gradually for stirring.

Do not touch the top surface if the HOT LED is Glowing. HOT LED gives an indication that the temperature of the top surface is above S0°C.
