All vessels are equipped with a rupture disc which produces a spontaneous pressure re-
lease upwards through the screw-on tube connections in case of excessive vessel pres-
sure. In some cases, such a spontaneous pressure release may occur after the vessel has
been removed from the microwave oven.
WARNING
Rupture discs used for overpressure protection!
Use only original Analytik Jena rupture discs and protective cover sheets. These can be
obtained from your local, authorized dealer or Analytik Jena.
Never use more than one rupture disc per vessel!
Only use rupture discs which are designed for the respective vessel!
All pressure vessels are equipped with a sealed connection to a gas collection system
which (without PM 40), in turn, must be connected to an exhaust system via a PFA vent
tube. The PFA tube is connected to the screw-on connection located in the center of the
top of the microwave. Any hot acid vapors released when the rupture disc activates are
safely removed through this PFA vent tube.
WARNING
Hot acid vapors may be released!
The supplied vent tubes must therefore always be properly connected and attached to
an exhaust system.
Make sure the PFA tube is securely attached so that it cannot pop off its connection fit-
ting in case of a percussive pressure burst as occurs when a rupture disc activates.
The system is equipped with a temperature control of all sample temperatures.
An emergency shut-off occurs in case of a rupture disc break.
Optionally, the system can be equipped with a pressure monitoring system for one or all
vessels.
For safety reasons, the microwave automatically switches itself off in case the magnet-
ron, the microwave oven, or the high voltage transformer overheats
In the following situations, the unit must be disconnected from the mains power supply
and be locked out to prevent accidental use:
if the unit evidences visible signs of damage
if unit parts or components are found to be loose
if the unit fails to operate
if the unit is to be stored for extended periods of time under unfavorable conditions
(e.g., outdoors, in very moist or humid environments)
