5 Installation

Before installing and removing the unit: make sure that no pressure is ap-
plied to the system. Note: If 0% is displayed and no pointer is visible, this
does not mean that no pressure is applied to the system !
We recommend horizontal installation for high medium temperatures.
The unit can be fixed to different process connections. Options are as follows:
1 Installation with seals to DIN EN 837-1
Insert the unit and the seal into the process connection with cylindrical pipe thread
G½ and tighten.
All seals to DIN EN 837-1 can be used if they are suitable for process connections
with cylindrical pipe thread, e.g. flat seals or double-edge sealing rings.
2 Installation with sealing tape
Insert the unit and the sealing tape into the process connection with G½ internal
thread (e.g. welding adapter) and tighten.
3 Installation at flange G½ (based on DIN 3852-11)
The sealing ring on the sensor is used as process seal.
The upper sealing area on the process connection must be flush with the tapped hole
and have a surface characteristic of min. Rz 6.3.
Grease the sensor thread with a suitable paste.
Insert the unit into the process connection.
Tighten it using a spanner. Tightening torque: 35 Nm.
After installation the analogue display can be rotated / adapted to the instal-
lation position (to do so wear protective gloves).
