DANGER
Suffocation hazard due to high concentration of inert gas.
Death by suffocation.
∅ Do NOT set up chambers in non-ventilated recesses.
Make sure that technical ventilation measures are active.
Respect the relevant regulations for handling inert gases.
When decommissioning the vacuum drying oven, shut off the inert gas supply.
4. Installation and connections
4.1 Vacuum expansion racks and rack holders
Vacuum expansion racks and rack holders can easily be removed from the chamber. This offers the
advantage of an inner chamber with smooth walls, which is easy to clean.
The rack holders can only be removed from the chamber after removing the expansion racks.
Rack holder installation: Align the rack holders to the cams in the bottom of the inner chamber and insert
them.
The low-loss heat transfer to the material occurs via the
aluminum vacuum expansion racks (also avail
able in
stainless steel as an option). The strong tension causes the
racks to fit tightly against the interior wall and their large-
surface contact area ensures rapid and effective heat
transfer.
The removable rack holders allow for easy positioning.
You can also remove the expansion racks for easy cleaning.
Do not remove them too often in order to prevent wear.
Figure 9: Using the expansion racks
• Pushing the locking lever: The expansion rack is released and can be removed.
• Pulling the locking lever: The expansion rack is pressed against the inner chamber walls.
Following each new tightening of an expansion rack, check that the lateral parts of the rack fit
closely over their whole surface to the inner chamber wall. This is necessary in order to ensure
the specified temperature exactitude.
NOTICE
Danger of invalid calibration caused by modified thermal conductivity when
changing between aluminum and stainless-steel racks.
Undefined heating performance.
∅ Do NOT change between aluminum and stainless-steel racks.
Operate the chamber with the supplied expansion racks only.
