Warning
Please carefully read the Instructions, and use the product safely under the direction of the
Instructions.
• Our products are under the patent protection of the origin country and other countries and
regions (including obtained patents and patents being applied for).
• We elaborately prepared the manual in the attitude of being responsible for the users. But we
can’t guarantee that the contents of the manual are fully correct. If any occasional or subsequent
loss is caused by the use of the Manual, the company will not be liable for this at all.
• The manual is a pure technical document, free of any implication or oblique hint of any third
party. Moreover, we won’t be liable for any user’s misunderstanding upon the printer’s error(s).
• The company and any of the company’s employees will not bear any liability for direct/indirect
loss of information or stop of business (if any) caused by the information of the manual or the
product it mentions.
• The company reserves the right to change specification and price of the product.
• If any information of the manual changes, we will not notify this otherwise.
• The manual and any content of it must not be copied, abstracted or modified in any form
without the company’s written approval in advance.
Safety Information
•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. When working under a vacuum in particular!
•Wear your personal protective equipment in accordance with the hazard category of the
medium to be processed. Otherwise there is a risk of:
-splashing liquids,
-body parts, hair, clothing and jewelry getting caught,
-injury as a result of glass breakage.
•CAUTION! Inhalation of or contact with media such as poisonous liquids, gases, spray mist,
vapors, dusts or biological and microbiological materials can be hazardous to user.
•Set up the device in a spacious area on an even, stable, clean, non-slip, dry and fireproof

5/ 20
surface.
•Ensure that there is sufficient space above the device as the glass assembly may exceed the
height of the device.
•Prior to each use, always check the device, accessories and especially the glass parts for
damage. Do not use damaged components.
•Ensure that the glass assembly is tension-free! Danger of cracking as a result of:
-stress due to incorrect assembly,
-external mechanical hazards,
-local temperature peaks.
•Ensure that the stand does not start to move due to vibrations respectively unbalance.
•Beware of hazards due to:
-flammable materials,
-combustible media with a low boiling temperature,
-glass breakage.
•CAUTION! Only process and heat up media that has a flash point higher than the adjusted
safe temperature limit of the heating bath that has been set.
•The safe temperature limit of the heating bath must always be set to at least 25 °C lower than
the fire point of the media used.
•Do not operate the appliance in explosive atmospheres, with hazardous substances or under
water.
•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.
•Tasks with the device must only be performed when operation is monitored.
•Operation with excess pressure is not permitted (for cooling water pressure see "Technical
Data").
•Do not cover the ventilation slots of the device in order to ensure adequate cooling of the
drive.
•There may be electrostatic discharges between the medium and the drive which could pose a
direct danger.
•The appliance is not suitable for manual operation.
•Safe operation is only guaranteed with the accessories described in the ”Accessories”
chapter.
•Refer to the operating instructions for the accessories, e.g. vacuum pump.
•Only use the device under an all side-closed exhaust, or a comparable protective device.
•Adapt the quantity and the type of distill and to the size of the distillation equipment. The
cooler must work properly. Monitor the coolant flow rate at the cooler outlet.
•The glass equipment must always be ventilated when working under normal pressure (e.g.
open outlet at cooler) in order to prevent a pressure build-up.
•Please note that dangerous concentrations of gases, vapors or particulate matter can escape
through the outlet at the cooler. Take appropriate action to avoid this risk, for example,
downstream cold traps, gas wash bottles or an effective extraction system.
•Evacuated glass vessels must not be heated on one side; the evaporating flask must rotate

6/ 20
during the heating phase.
•The glassware is designed for operation under a vacuum of up to 10 mbar. The equipment
must be evacuated prior to heating (see chapter “Commissioning”). The equipment must only
be aired again after cooling. When carrying out vacuum distillation, uncondensed vapors
must be condensed out or safely dissipated. If there is a risk that the distillation residue could
disintegrate in the presence of oxygen, only inert gas must be admitted for stress relief.
•CAUTION! Avoid peroxide formation. Organic peroxides can accumulate in distillation and
exhaust residues and explode while decomposing!
•Keep liquids that tend to form organic peroxides away from light, in particular from UV rays
and check them prior to distillation and exhaust for the presence of peroxides. Any existing
peroxides must be eliminated. Many organic compounds are prone to the formation of
peroxides e.g. dekalin, diethyl ether, dioxane, tetrahydrofuran, as well as unsaturated
hydrocarbons, such as tetralin, diene, cumene and aldehydes, ketones and solutions of these
substances.
•DANGER OF BURNING! The heating bath, tempering medium, evaporator piston and glass
assembly can become hot during operation and remain so for a long time afterwards! Let the
components cool off before continuing work with the device.
•ATTENTION! Avoid delayed boiling! Never heat the evaporating flask in the heating bath
without switching on the rotary drive! Sudden foaming or exhaust gases indicate that flask
content is beginning to decompose. Switch off heating immediately. Use the lifting
mechanism to lift the evaporator piston out of the heating bath. Evacuate the danger zone
and warn those in the surrounding area!
•When the device is switched off or the power supply disconnected, the internal safety lift
removes the evaporator piston from the heating bath.
•CAUTION! Never operate the device when the evaporator piston is rotating and the lift is
raised. Always lower the evaporator piston into the heating bath first before starting the
rotation drive. Otherwise hot tempering medium may be sprayed out!
•Set the speed of the drive so no tempering medium is sprayed out as a result of the
evaporator piston rotating in the heating bath. If necessary, reduce the speed.
•Do not touch rotating parts during operation.
•Imbalance may result in uncontrolled resonance behavior of the device or assembly. Glass
apparatus may be damaged or destroyed. In the event of unbalance or unusual noises,
switch off the appliance immediately or reduce the speed.
•The appliance does not start up again automatically following a cut in the power supply.
•The device is only disconnected from the power
•supply network if the device power switch is off or the plug is pulled out.
•The socket for the mains cord must be easily accessible.
•The voltage stated on the type plate must correspond to the mains voltage.
•Socket must be earthed (protective ground contact).
•Removable parts must be refitted to the appliance to prevent the infiltration of foreign objects,
liquids etc.
•Protect the appliance and accessories from bumps and impacts.
•The appliance may only be opened by experts.
