Safety instructions for properly locating and installing the device
Danger of burns and property damage if unsuitable bath fluid is
used.
Proper use of the temperature control system includes controlling the
temperature of a liquid in a reactor or similar vessel.
We do not know which substances you will need to use.
Many substances are:
•
combustible, flammable, or explosive
•
hazardous to health
•
hazardous to the environment
•
in other words:
dangerous
.
The user bears sole responsibility for handling these materials
!
The following questions are meant to help recognize potential
hazards and minimize risks.
•
Are all tubes and electrical cables securely attached and laid?
Watch for:
sharp edges, hot surfaces during operation, moving mechanical
parts, etc.
•
Will hazardous vapors or gases be produced during heat-up?
Is it necessary to work under a fume hood?
•
What must be done if a hazardous substance is spilled onto or into
the unit?
Obtain information about the substance before beginning work and
define decontamination methods.
Escaping vapors/gases
•
Vapors/gases may develop, especially at higher working
temperatures. The unit will vent these vapors/gases to ensure
optimum performance. Operation under a fume hood is
recommended.
Ensure good ventilation and airflow at the place of installation.
It is advisable to continue circulation for a certain amount of time after
you are finished working with the temperature control system. You
should also set the working temperature to approximately 20 °C [68 °F]
in order to uniformly drop the temperature in the closed loop. This will
avoid overheating of the bath fluid and dangerous draining conditions.
Inspect safety devices at least twice per year:
•
High temperature cut-off device.
Use a screwdriver to turn the adjustable high temperature cut-off
down to the current bath temperature (this will shut off the unit).
•
Low-level safety
The float switch on this unit cannot be activated manually for the
purpose of checking functionality. Therefore, you should observe the
five-stage level indicator each time you refill the unit.
If the bath fluid becomes thick or cracks during operation, the
temperature control system must be cleaned by qualified personnel.
This can be avoided by changing the fluid regularly
