Bedew protection facility (operation line 1)
The bedew protection condensates the chamber humidity at the coldest point in order to avoid the samples becoming wet from 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 absolutely necessary to prevent condensation on the charging
material.
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 it can also be
activated 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.

In the program table the state of operation
line 1 for bedew protection is represented
in the column “Sk”:
On = 00000001
Off = 00000000
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.
