Translation of the original operating manual
Timer Evaporation
The time can be set between 1 minute and 200 hours. Using the down key
as of the time 00:01 h:m calls up the symbol
. The timer is now
deactivated and the RVC operates continuously.
Timer Heating
The value that is set under “Timer Evaporation” is also used for “Timer
Heating”.
For some evaporation processes, however, it makes sense to reduce the
heating time. In this case, the value “Timer Heating” must be changed. The
value “Timer Heating” is always lower or equal to the value “Timer
Evaporation”.
Temperature
The temperature can be set between
–80°C and +60°C.
NOTE
Because the RVC has no active cooling, it is not possible to reach
temperatures below room temperature. Under certain conditions (e.g. if a
frozen product is loaded into the unit) it may be reasonable to select a
temperature below room temperature.
