IKA C-MAG HS 7 control Instructions Manual page 5

› Beware of hazards due to:
- flammable materials,
- combustible media with a low boiling temperature,
- glass breakage,
- incorrect container size,
- overfilling of media,
- unsafe condition of container�
› Process pathogenic materials only in closed vessels under a suitable fume hood�
Warning!
› The safety temperature must be set in accordance with EN 61010-2-010 Chapter
"Requirements for devices containing or using flammable liquids"�
- The surface temperature of the flammable medium that is exposed to air may not exceed
its flash point�
A danger usually arises if a medium is heated in open vessels�
- The surface temperature of the heating device (e�g� the mounting plate) may not exceed
the value of (t - 25) °C (= set value of the safety circuit) on the surface of the flammable
medium and in contact with air, whereby t is the fire point of the liquid�
A danger usually arises if a medium is heated in glass vessels (glass breakage)�
If a setting made by the user (medium temperature or safety temperature) could bring a
flammable medium into a state in which the conditions mentioned above could be exceeded,
additional measures must be introduced that will protect the user from this danger�
› The heating plate can heat up due to the action of the magnets at high motor speeds, even
if the heater is switched off�
› Please consider any possible contaminations and unwanted chemical reactions�
› It may be possible for wear debris from rotating accessory parts to reach the material being
processed�
› When using PTFE-coated magnetic bars, the following has to be noted: Chemical reactions
of PTFE occur in contact with molten or solute alkali metals and alkaline earth metals, as well
as with fine powders of metals in groups 2 and 3 of the periodic system at temperatures
above 300 °C – 400 °C� Only elementary fluorine, chlorotrifluoride and alkali metals attack
it; halogenated hydrocarbons have a reversible swelling effect�

/// Procedures during sample runs
Caution!
› Wear your personal protective equipment in accordance with the hazard category of the
media to be processed� There may be a risk from:
- splashing and evaporation of liquids,
- ejection of parts,
- release of toxic or combustible gases�
› Reduce speed if:
- medium splashes out of vessel because the speed is too high,
- device is not running smoothly,
- container moves on the base plate,
- an error message is displayed�

/// Accessories
› Safe operation is guaranteed only with the use of original IKA accessories�
› Ensure that the external temperature sensor is inserted into the medium to a depth of at
least 20 mm when connected�
› Always disconnect the plug before attaching accessories�
› Accessories must be securely attached to the device and cannot come off by themselves� The
centre of gravity of the assembly must lie within the surface on which it is set up�
› Observe the operating instructions of the accessories�
/// Power supply / Switching off the device
Warning!
› The device will automatically restart in mode B following any interruption to the power
supply�
› The voltage stated on the type plate must correspond to the mains voltage�
› The outlet for the mains plug must be easily accessible�
› The device can only be disconnected from the mains supply by pulling out the mains plug or
the connector plug�
› After continuously running for 100 hours the device will limit the maximum heating power
by 10% for self-protection�
/// For protection of the equipment
› The device may only be opened by qualified and IKA approved experts�
› Do not cover the device, even partially e�g� with metallic plates or film� This may result in
overheating�
› Protect the device and accessories from bumps and impacts�
› Keep the base plate clean�
› Observe the minimum distances:
- between devices min� 100 mm,
- between device and wall min� 100 mm,
- above the device min� 800 mm�
> 100 mm > 100 mm
