Opening the lid
The lid can only be opened if the rotor is at a standstill. It is not possible to
open the lid during an evaporation process.
DANGER
Hazards of burns on hot surfaces!
During the evaporation process, the housing, the lid and the interior of the
rotational vacuum concentrator can reach surface temperatures of more
than +50°C.
Risk of burns!
Before starting an evaporation process, the vacuum pump and the cooling
trap should warm-up until they reach their respective operating
temperatures.
For this purpose, the warm-up phase can be started. The rotor can
optionally be installed. The warm-up time and the set value for heating can
be selected (see chapter 6.5.3.5 - "Options").
During the warm-up:
• The rotor chamber is preheated - with or without rotor - when the lid is
closed.
• The vacuum pump is switched on.
• • The cooling trap is switched on if it is connected via the control
system with the rotational vacuum concentrator (see chapter 5.6 -
"Connection of a vacuum pump and/or a cooling trap"). If there is no
connection, the cooling trap must be switched on separately.
When the preset warm-up time is over, the control unit displays the
following message:

• Open the lid and remove the rotor in order to load it with the product or
insert the loaded rotor.
