Evacuation - Binder VDL Series Operating Manual

Fire and explosion hazard when exceeding the auto-ignition temperature of the sol-
vent.
Serious injury or death from burns and / or explosion pressure.
 Take the auto-ignition temperature from the safety specifications of the solvent. In the
case of solvent mixtures, use the lowest auto-ignition temperature.
 Correctly set the maximum drying temperature (safety temperature) on the tempera-
ture safety device according to the information panel "Temperature setting".
 Introduce measures to prevent mixing up the material to be dried.
 Before starting a new drying process with a different auto-ignition temperature, check
the auto-ignition temperature with the safety specifications of the solvent.
If, during loading material containing solvents falls down, it is possible that the solvent or solvent vapors
will spread outside the loading area, e.g. to the side of or below the chamber. The chamber must be dis-
connected from the power immediately (pull out the power plug or operate the customer's emergency
stop switch).
The chamber is not to be installed and operated in potentially explosive areas.
Explosion hazard due to explosive mixtures in the vicinity of the equipment.
Serious injury or death from burns and / or explosion pressure.
∅ Ensure that NO solvents or explosive solvent-air mixtures are located in the area
around the chamber.
 Disconnect the chamber from the power immediately if there is explosive atmosphere in
the area around the chamber outside the indicated loading area.

Evacuation

Starting situation: The vacuum pump / vacuum system is connected and ready for operation.
Preparation:
• Make sure that the "Manual ventilation" plug (7) for emergency ventilationin case of a power failure,
which is located on the chamber rear, is closed
• Make sure that the pressure control is activated.
• Turn on the vacuum pump. The pump shall continue running during the entire drying procedure.
• Set the desired pressure set-point on the controller (chap. 10).
• Monitor the internal pressure on the controller display
As long as there is a vacuum, never try to open the oven by force.
