After completing the drying process or when cancelling the drying process
When the pressure drops to the pressure set-point, the drying process is finished. If the drying monitoring
(chap. 11.6) is activated, a corresponding message is displayed.
•
Make sure that the technical ventilation is activated
•
Make sure that equipotential bonding has been established according to the grounding con-
cept
□
•
For ventilation, set the pressure set-point to atmospheric pressure
□
•
Switch the vacuum drying oven on the controller to standby mode (not completely de-
energized)
□
•
Make sure that the user's equipment is ESD protected.
•
Remove the drying material
□
•
Continue sweeping the electrical installation area and controller housing with an overpres-
sure of at least 25 Pa (recommendation: 40 Pa) for at least 10 minutes (recommended).
Check the excess pressure on the manometer. Only then shut off the compressed air or inert
gas supply
□
For emptying the pump
•
Make sure that the pump is turned off.
□
•
Make sure that the technical ventilation is activated
•
Make sure that equipotential bonding has been established according to the grounding con-
cept
□
•
Make sure that the user's equipment is ESD protected.
•
Remove the full condensate catchpot of the pump
□
Before starting a new drying process
In case of a new solvent with a different auto-ignition temperature:
•
Determine the auto-ignition temperature of the solvent from its safety specifications. In the
case of solvent mixtures, use the lowest auto-ignition temperature
□
•
Make sure that the technical ventilation is activated
•
Make sure that equipotential bonding has been established according to the grounding con-
cept
□
•
Sweep the area for electrical equipment and the controller housing with compressed air or
inert gas at maximum overpressure for at least 10 minutes
□
•
Turn on the chamber and check the settings (drying temperature, pressure set-point and
safety controller setting)
□
•
Now you can load the chamber and start the new drying process. Follow all safety measures
