16Safety instructionsFor your protection• Read the operating instructions in full before starting upand follow the safety instructions.• Keep the operating instructions in a place where they can beaccessed by everyone.• Ensure that only trained staff work with the appliance.• Follow the safety instructions, guidelines, occupational healthand safety and accident prevention regulations.• Wear your personal protective equipment in accordance withthe hazard category of the medium to be processed. Otherwisethere is a risk of splashing liquids.• When emptying the device use only the handles to carry and hold it.• Set up the device in a spacious area on an even, stable, clean,non-slip, dry and fireproof surface.• Prior to each use, always check the device and accessories fordamage. Do not use damaged components.• Caution! Only process and heat up media that has a flash pointhigher than the adjusted safe temperature limit of the heatingbath that has been set.The safe temperature limit of the heating bath must always beset to at least 25 °C lower than the fire point of the media used.Risk of burns! During operation,the heating bath housing can gethot.When working with temperaturesensitive mediums please consider: upon continuous operationwith high speed and a room temperature of 20 °C a warming upof the housing up to 40 °C is possible.• Prior to filling or emptying the heating bath, the device must beswitched off and disconnected from the power supply at theplug.• Only fill or empty the heating bath when it is cold.• Empty the heating bath prior to transporting it.• Never operate the heating bath without tempering medium.Caution! The preferred temperingmedium in the heating bath is wa-ter (up to approx. 80 °C). Low vis-cosity silicone oils (50 mPas) with aflash point > 260 °C are also permitted.There is a risk of burning when using tempering media with low-er flashpoints!• Before use, calculate the optimum fill level of the tempering me-dium! Pay special attention to the change in volume caused byheating and the displacement that occurs when immersing anobject, for example, an evaporating flask.• When using the heating bath in conjunction with a rotary evap-orator, the heating bath temperature must not be allowed to riseto a value higher than the boiling point of the solvent at normalpressure, since if the evaporating flask glass were to break therewould be a hazard due to liquid spraying out (for instance break-age of the evaporating flask glass during distillation of waterusing a silicone oil bath).• When working with the IKA ® rotary evaporator, be aware of ahazard arising from breakage of the evaporating flask glass.• Be aware of a hazard due to lack of grip on a wet evaporatingflask, in particular when operating the IKA ® HBR 4 digital/control heating bath with silicone oil!• When using as a water bath, the use of demineralised water isrecommended.• Always observe the minimum fill level of one litre when using oilas the tempering medium.• Ensure that the interfaces are not soiled.• Beware of hazards due to flammable materials.• Only process media that will not react dangerously to the extraenergy produced through processing. This also applies to anyextra energy produced in other ways, e.g. through light irradia-tion.• Do not operate the appliance in explosive atmospheres, withhazardous substances or under water.• Refer to the operating instructions for the accessories.• Safe operation is only guaranteed with the accessories describedin the ”Accessories” chapter.• Always disconnect the plug before fitting accessories.• After an interruption to the power supply, the device can bestarted up again in operating mode B and C.• The device is only disconnected from the power supply networkif the device power switch is off or the plug is pulled out.• The socket for the mains cord must be easily accessible.Caution - magnetism!Beware of possible effects from themagnetic field (pacemakers, datamedia).For protection of the equipment• The voltage stated on the type plate must correspond to themains voltage.• Socket must be earthed (protective ground contact).• Protect the appliance and accessories from bumps and impacts.• The appliance may only be opened by experts.In conjunction with IKA® rotary evaporator, IKA ® glassware and solvents• Solvents can be hazardous to health. Therefore comply with therelevant warnings and refer to the relevant safety data sheet(Internet).IKA ® Glassware• The glassware is designed to be used at vacuums down to 1 mbar.Coated glassware• Coated glass components offer protection against the glasssplintering if it breaks under vacuum. Please note that whencoated glassware is used it is only to the condenser and receiv-ing flask to which coating is applied.• For operational reasons, the coating is not applied to the entirearea of the glass. In particular on the condenser there are areasto which no coating is applied, especially at places where jointsand connections are made.• Evaporating flasks with special heat-resistant coatings are avail-able as accessories.• The coating does not offer any protection against damage tothe glass or breakage of the glass.• Do not use the glass component if its coating is damaged.• The use of coated glassware does not release you from the obli-gation when the device is in use to enclose it on all sides with anextractor hood or to employ an appropriate safety device.DANGERDANGERATTENTION |
