Start up

Solvent-containing air penetrating and concentration in the electrical area of the
chamber.
Explosion hazard.
 Before turning on the chamber via the key switch (1), sweep the area for electrical
equipment at least 15 minutes with compressed air or inert gas. Sweeping the area for
electrical equipment must take place during the entire operation, as otherwise the VDL
vacuum drying oven will shut off at all poles.
After connecting the supply lines (chap 4) and checking all safety instructions and conditions of installa-
tion and safe operation, turn on the chamber via the key switch (1):
• Position 0: Oven is not operating
No consumption of compressed air or inert gas in the area for electrical equipment. If the fine dosage
valve (6) is open, inert gas may be used and can reach the ambient air.
• Position I: Oven is operating
If no indication appears in the display of the program controller RD3, the compressed air sup-
ply is probably not properly connected.
Warming chambers may release odors in the first few days after commissioning. This is not a quality de-
fect. To reduce odors quickly we recommend heating up the chamber to its nominal temperature for one
day and in a well-ventilated location.
