10. Bedew protection facility (Operation line 1)
When operating the chamber without humidification, the bedew protection condensates the chamber hu-
midity at the coldest point in order to avoid the samples becoming wet by condensation. Bedew protection
is performed by the evaporator and can be programmed On/Off via operation line 1 in Manual Mode
(HAND) and in Program Mode (AUTO).
Use the bedew protection only if it is necessary to prevent condensation at the charging mate-
rial.
Use the bedew protection only when operating the chamber without humidification.
When the bedew protection is enabled (operation line 1 = On) the refrigeration machine keeps operating
within warming-up phases (On = refrigeration machine operating, Off = refrigeration machine off).
•
If possible, use the bedew protection only during warm-up phases. If necessary, you can also
activate it during hold phases.
•
Do NOT use the bedew protection above a temperature set-point of +20 °C / 68°F maximum.
To obtain optimal warming results without condensation on the samples, program a heating gradient of
approx. 0.5 °C/min.

Operation line 1 = bedew protection
In the program table, the state of opera-
tion line 1 for bedew protection is repre-
sented in the column “Sk”:
On = 0000000 1
Off = 0000000 0
Example:
Operation line 1 is activated in the first
program section and remains active up
to 20 °C /
68°F .
Then the refrigeration machine turns off
automatically.
