Safety instructions
General information:
• Read the operating instructions completely before
starting up and follow the safety instructions.
• Keep the operating instructions in a place where it can be
accessed by everyone.
• Ensure that only trained staff work with the device.
• Follow the safety instructions, guidelines, occupational
health, safety and accident prevention regulations.
• Set up the device in a spacious area on an even, stable,
clean, non-slip, dry and reproof surface.
• Do not operate the device in explosive atmospheres,
with hazardous substances.
• Protect the device and accessories from bumping and
impacting.
• Check the device and accessories for damage before
each use. Do not use damaged components.
• Safe operation is only guaranteed with the accessories
described in the ”Accessories” section.
• The socket for the mains cord must be easily accessible.
• Socket must be earthed (protective ground contact).
• The voltage stated on the type plate must correspond to
the mains voltage.
• The device can only be disconnected from the mains supply by pulling out the mains plug or the connector plug.
• Disconnect the mains plug before attaching or changing
any accessories.
• Disconnect the mains plug before cleaning, maintenance
and transportation of the unit.
• The device must only be opened by trained specialists,
even during repair. The device must be unplugged from
the power supply before opening. Live parts inside the
device may still be live for some time after unplugging
from the power supply.
Coverings or parts that can be re-
NOTICE
ensure safe operation, for example to keep foreign objects and liquids, etc. from getting into the device.
• The device may only be used as prescribed and as de-
scribed in these operating instructions. This includes operation by instructed specialist personnel.
• When using critical or hazardous materials in your processes, IKA® recommends to use additional appropriate
measures to ensure safety in the experiment. For ex-
ample, users can implement comprehensive monitoring
equipment.
• Process pathogenic material only in closed vessels under
a suitable fume hood. Please contact IKA® application
support if you have any question.

• A laboratory circulator refrigerates and circulates uid
according to specied parameters. This involves hazards
due to low temperatures and general hazards due to the
device of electrical energy. The user is largely protected by the device of relevant standards. Further hazard
sources may arise due to the type of tempering uid,
e.g. by exceeding or undercutting certain temperature
thresholds or by the breakage of the container and reaction with the refrigeration carrier fluid. It is not possible
to consider all eventualities. They remain largely subject
to the judgment and responsibility of the operator. For
this reason, it may become necessary for user to take
other precautionary safety measures.
• Insucient ventilation may result in the formation of explosive mixtures. Only use the device in well ventilated
areas.
• Use suitable hoses for connection.
• Secure hoses and tubes against slippage and avoid kinks.
• Check hoses, tubes and bath at regular intervals for possible material fatigue (cracks/leaks).
• When device is used for external circulation, extra pre-
caution must be taken for cold fluid leakage due to
damaged hose.
Do not start up the device if:
DANGER
- It is damaged or leaking
-
Cable (not only supply cable) is damaged.
Fluids:
CAUTION
the chemical hazards that may be associated with the
bath fluid used. Observe all safety warning for the fluids.
• Depending on the bath uid used and the type of opera-
tion or toxic can arise. Ensure suitable extraction.
• Do not use any uid which may cause dangerous reac-
tions during processing.
• Only use recommended bath uid. Only use non-acid
and non corroding fluid.
NOTICE
the section "Filling and draining").
• Continuous monitoring of the lling level of the bath uid
is required.
• For optimum temperature stability, the uids viscosity
should be 50 mm2/s or less at its lowest operating temperature. This permits good fluid circulation and minimizes heating from the pump.
• Untreated tap water is not recommended. It is recom-
mended to use distilled water or high purity water (ion
exchangers) and add 0.1 g soda (sodium carbonate
Na2CO3) /liter, to reduce corrosive properties.
Only use the uids, which fulll the
requirements for safety, health and
device compatibility. Be aware of
Never operate the device without
sucient uid! Check the uid level detection at a regular basis (see
• After a power failure during operation, the device may
start automatically (depending on operating mode).
• Transport the device with care.
• Do not transport or empty the bath while it is still cold.
Check the temperature of the bath fluid before draining.
• Always empty the bath before moving the unit.
NOTICE
Always empty the bath if the unit
is unused for long time.
Correct use
• Use:
Use RC (Refrigerated Circulators) for cooling and circulat-
ing fluids.
Intended Use: Tabletop device
• Range of use (indoor use only):
- Laboratories -Schools
- Pharmacies - Universities
NOTICE
Don't use following uids:
- Untreated tap water
- Acids or bases
- Solutions with halides: chlorides, uorides, bromides,
iodides or sulfur
- Bleach (Sodium Hypochlorite)
- Solution with chromates or chromium salts
- Glycerine
- Ferrous water.
This instrument is suitable for use in all areas except:
- Residential areas
-
Areas that are connected directly to a low-voltage supply
network that also supplies residential areas.
The safety of the user cannot be guaranteed:
- If the device is operated with accessories that are not
supplied or recommended by IKA® .
- If the device is operated improperly or in contrary to the
IKA® specications.
- If the device or the printed circuit board are modied by
third parties.

Unpacking
• Unpacking:
- Please unpack the device carefully
- In the case of any damage a detailed report must be
sent immediately (post, rail or forwarder).
Preparations
• Setting up:
- Place the unit on an even, stable, clean, nonslip, dry
and reproof surface.
- Keep at least 20 cm of open space on the front and
rear side.
- The place for installation should be large enough and
provide sucient air ventilation to ensure the room
does not warm up excessively because of the heat
from device radiates to the environment.
- Do not set up the device in the immediate vicinity of
heat sources and do not expose to sun light.
- Cooling machine, pump motor and electronics produce intrinsic heat that is dissipated via the venting
grids! Never cover these venting grids!
NOTICE
After setting up the device, wait at
least one hour before starting the
operation.

- Via a hose to the “Overflow” connection, overowing
fluid can be directed into a suitable vessel. The vessel
should be positioned lower than the “Overflow” connection.
- Connect the “Backflow” connector to IKA® calorim-
eter with a suitable hose.
• Connecting the tubings:
- Unscrew the union nuts and stoppers using a wrench
from the pump connection IN (6, see Fig. 1) and OUT
(7, see Fig. 1).
