Installing the assembly into the process
!
Note!
Before installing the assembly into the process check the seal between the flanges.
1.
Move the assembly into the "Service" position (electrode holder inserted in the assembly).
2.
Secure the assembly to the tank or the piping using your selected process connection.
3.
Follow the instructions for compressed air and rinse water connection (if used) given in the
following chapters.
3.3.3
Pneumatic connection (optional)
Requirements:
• air pressure of 5 to 6 bar (72.5 to 87 psi)
• air must be filtered (40 µm) and be free of water and oil
• no continuous air consumption
• minimum nominal diameter of the air lines: 4 mm (0.16 ").
"
Caution!
There must be a pressure-reducing valve upstream if the air pressure can increase to above
6 bar (87 psi) (including any short pressure surges).
We recommend you also use a pneumatic throttle for lower pressures. This results in a smoother
assembly operation. Hauser offers such a throttle as an accessory (see chapter
"Accessories").
