JULABO LH 50 Highly Dynamic Temperature Control Systems - Manual (Page 17)

17
The following questions shall help to recognize possible dangers and to reduce the
risks to a minimum.
 Are all tubes and electrical cables connected and installed?
Note:
sharp edges, hot surfaces in operation, moving machine parts, etc.
 Do dangerous steams or gases arise when heating?
Is an exhaust needed when working?
 What to do when a dangerous substance was spilled on or in the unit?
Before starting to work, obtain information concerning the substance and
determine the method of decontamination.
Caution: Escape of vapors / gas
The necessity of degassing requires that a closed system is not entirely sealed.
Especially at increased working temperatures vapor / gas may escape.
Ensure sufficient ventilation at the place of installation!
Notice:
When you have finished the application, it is recommended to keep on circulating the
liquid in the bath or the external system for some time. Simultaneously set the
working temperature to +20 °C to allow the temperature in the system to decrease
slowly.
Thus fractional over-heating of the bath liquid is prevented.

Notice:
Please check the safety device from time to time.
 Excess temperature protection according to IEC 61010-2-010
With a screw driver turn back the adjustable excess temperature protection until
the shut-down point (actual temperature).
 Low level protection
To check the function of the float of this unit it cannot be operated manually.
The 5-graded level display should therefore be observed whenever refilling.
If the bath liquid thickens or cracks, the instrument should be cleaned and
checked by qualified personnel.
