3 Installation

3.1 Notes for Installation

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 ... +60 C
Rel. humidity: max. 80% up to 30 C, max. 50% at 40 C, non-condensing
Ambient pressure: 860 - 1060 hPa (mbar)

3.2 Vacuum Connection

Dirt and damage, especially at the vacuum flange, have an adver-
se 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 com-
ponents.
Remove the protective cover (is required again during maintenance work!)
Make vacuum connection via ISO KF small flange or CF conflat flange
For small flange connection use clamps that can be opened and closed with
appropriate tools only, use sealing rings with a centering ring
Make sure that the sensor flange is connected to ground, e.g. by having
electrical contact to the grounded vacuum chamber (use metallic clamps)
The transducer may be mounted in any orientation. Mounting with the flange to
the top, however, can lead to early contamination and malfunction. An upright ori-
entation with flange to the bottom is to be preferred in order to keep particles and
condensates out of the sensor cell. Further the transducer is adjusted in the upright
position ex works. Different orientation -without readjustment- will lead to reduced
accuracy at pressures above 20 mbar.
When mounting the transducer avoid forced twisting or violent ope-
ning. This can damage the transducer!
