3 Installation
3.1 Installation Notes
Unauthorized modifications or conversions of the instrument are
not allowed!
Installation location: Indoor
For not fully air conditioned open buildings and operation rooms:
Temperature: +5°C ... +50°C
Rel. Humidity: 5 - 85%, not condensing
Air pressure: 860 - 1060 hPa (mbar)
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 or NPT thread; the
vacuum vessel and thus the sensor should be electrically grounded. If a tube
connection is made the sensor should be separately grounded or alternatively
the VD84 should be powered by battery!
- Use metal 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 dam-
age your health.
