● Remove the protective cover (is required again during maintenance work!).
● Make vacuum connection via ISO KF small flange or thread connector.
● For small flange connection use clamps that can be opened and closed with appropriate tools on-
ly, use sealing rings with a centering ring.
● Make sure that the sensor flange is connected to ground, e.g. by having electrical contact to
grounded vacuum chamber (use metallic clamps).
The device may be mounted in any orientation. Mounting with the flange to the top, however, can
lead to early contamination and malfunction. An upright orientation with flange to the bottom is to
be preferred in order to keep particles and condensates out of the sensor cell. Further the device is
adjusted in the upright position ex works.
