degasing activ
If the temperature system is operated an automatic degasifying is
carried out after the start.
During the degasifying unwelcome components of the bath liquid
are are drawn off .
Examples:
Air bubbles which were enclosed in the bath liquid during the
filling for the unit.
Slightly volutile components which are eventually in the fluid.
Eventually existing water components, which reached the bath
liquid during the storage.
The automatic degasifying is a part of the program in the unit,
which is always active in the background. Experience shows that
the activity is only noticed after a first or new filling of the unit.
During the heating-up phase, e.g. to a working temperature of
180°C, the VFD-Info-Display shows >DEGAS<.
Parallely to this, in line 4 in the DIALOG-DISPLAY the message
>Degasifying active< is inserted. In this phase the temperature rise
is stopped, the pump motor and the ventilation valve are activated
alternately (audible). During the heating-up phase this degasifying
mode can be repeated with the most different temperatures.
L
The automatic degasifying can be stopped by :
Operating the key
or
adjusting the set temperature on at least 50°C lower than the
current set temperature.
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!
•
With different substances the change-over to the steam phase and therefore also
an enormous change of volume is carried out very quickly. The fluid, for which
there is no more room in the internal reservoir, now has to drain off controlled via
the overflow.
Important:
Connect a piece of tubing to the overflow connector (15) and drain into a suitable
vessel. (min. 2 liters)
(M16x1 / wrench 19 mm), which always has to be
placed lower than the exit „Overflow“
