• 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-

The proportional coecient Kp is the controller ampli-
cation and determines how strongly the control devia-
tion (the difference between the target temperature and
actual temperature) directly affects the control variable
(cooling down time). Kp values that are too large can
lead to the controller overshooting.
Integral time of PID (Ti 1)
The integral time Ti (s) is the correction time and determines how strongly the duration of the control deviation affects the control variable. Ti compensates an existing control deviation. A high Ti means a smaller and
slower effect on the control variable. Ti values that are
too small can lead to instability of the controller.
Differential time of PID (Td 1)
The differential time Td (s) is the derivative time and determines how strongly the rate of change of the control
deviation affects the control variable. Td compensates
for rapid control deviations. A high Td means a smaller
and slower effect on the control variable. Td values that
are too small can lead to instability of the controller.

Maintenance and cleaning
To avoid contamination, it is essential to check and change
the bath fluid from regularly.
If water is used for bath uid, we recommend to add Water bath protective media. The protective media stops the
growth of algae, bacteria and other microorganisms with
its bactericidal effectiveness. It protects the bath fluid and
provides a long period of use for the fluid.
To maintain the full cooling performance, maintain the
condenser dust lter from time to time.
• Switch off the device and disconnect mains cable.
• Open the front venting grid.
• Remove the bracket (see Fig. 7).
• Clean condenser dust lter with a vacuum cleaner or wash
the lter in the water and dry the it before assembly.
