3.2 Vacuum Connection

Dirt and damage, especially at the vacuum flange, have an ad-
verse effect on the function of this vacuum component.
Please take account of the necessary instructions with regard to
cleanliness and damage prevention when using vacuum compo-
nents.
- Remove the protective cover (is required again during maintenance work!)
- Make vacuum connection via small flange DN16 ISO KF
- Use clamps, that can be opened and closed with appropriate tools only (e.g.
strap retainer-tension-ring)
- Use sealing rings with a centering ring.
Overpressure in the vacuum system > 1 bar
Accidental or unintended opening of clamp elements under
stress can lead to injuries due to parts flying around!
Overpressure in the vacuum system 1.5 to 4 bar
KF flange connections with elastomer sealings cannot withstand
such pressures. Process media thus can leak and possibly
damage your health.
