Safety instructions
If the power switch is not within
reach when device is operating, an
EMERGENCY STOP switch that
can be easily accessed must be installed in the work area.
• A laboratory circulator refrigerates and circulates fluid ac-
cording to specified parameters. This involves hazards due
to high and low temperatures and general hazards due to
the device of electrical energy. The user safety can not be
ensured simply with design requirements on the part of
the device. Further hazard sources may arise due to the
type of tempering fluid, e.g. by exceeding or undercut-
ting certain temperature thresholds or by the breakage of
the container and reaction with the carrier fluid. It is not
possible to consider all eventualities. They remain largely
subject to the judgment and responsibility of the opera-
tor. For this reason, it become necessary for user to take
other precautionary safety measures.
• When device is used for external circulation, extra precau-
tion must be taken for cold fluid leakage due to damaged
hose.
- 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).
Do not start up the device if:
-It is damaged or leaking
-Cable (not only supply cable) is
damaged.
• After a power failure during operation, the device may
start automatically (depending on operating mode).
Because of the heavy weight of
the device, at least two person are

tion or toxic can arise. Ensure suitable extraction.
• Do not use any fluid which may cause dangerous reac-
tions during processing.
•Only use recommended bath fluid. Only use non-acid and
non corroding fluid.
Never operate the device without
sucient fluid! Check the fluid level
detection at a regular basis (see the
section “Filling and draining”).
• Continuous monitoring of the filling level of the bath fluid is
required.
• To ensure a sucient fluid circulation, the viscosity of the
bath fluid must not exceed of 50mm2/s at the lowest op-
erating temperature.
• Untreated tap water is not recommended. It is recom-
mended to use distilled water or high purity water (ion ex-
changers) and add 0.1 g soda (sodium carbonate Na

)
/liter, to reduce corrosive properties.
Don’t use following fluids:
-Untreated tap water
-Acids or bases
-Solutions with halides: chlorides, fluorides, bromides,
iodides or sulfur
- Bleach (Sodium Hypochlorite)
-Solution with chromates or chromium salts

Unpacking
• Unpacking:
- Please unpack the device carefully
- Any damage should be notified immediately to the
shipping agent (post oce, railway network or logistics
company).
Preparations
• Setting up:
- Place the unit on an even, stable, clean, nonslip, dry
and fireproof 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 sucient 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!
Note: After setting up the device, wait at least one hour
before starting the operation to avoid the damage to the
cooling system.
• Connecting the tubings:
- Unscrew the union nuts and stoppers using a wrench
(SW 19)from the pump connection IN (8) and OUT (9).

- Connect the hoses for circulating the external system to
the pump connectors M 16 x 1 for IN and OUT directly
or with the olives.
- Screw the hose olive to the pump connection IN and
OUT with union nuts. Slide the hoses (NW 12) onto the
olives. The hoses must be secured with suitable clamps.
- Via a hose to the “Overflow” connection, overflowing flu-
id can be directed into a suitable vessel. The vessel should
be positioned lower than the “Overflow” connection.
In case of closed external system, if there is in any case
no risk of exceeding the maximum fluid level, you can
close the “Overflow” connector with the included
overflow cap. This minimizes the energy loss and pro-
tects, in case of long-term applications with low tem-
peratures and high humidity, against unwanted water
input and the associated volume increase.
Check fluid heat expansion!
- Connect the “Backflow” connector to IKA calorimeter
with a suitable hose.
When IKA calorimeter is not connected, please close the
“Backflow” connector with included backflow cap.
