3.3.2 Installing the assembly into the process
Move the assembly into the "Service" position (outer sleeve inserted in the assembly)
and secure the assembly to the tank or the piping using your selected process
connection.
!
Note!
Depending on the process connection, please observe the following:
•
Check the installation of the flange seal between the flanges.
3.3.3 Rinse water connection (optionally)
You can rinse the sensor in the Service position with a second ball valve for the rinse
chamber (see Accessories).
Connect the rinse water pipe to the designated rinse nozzle. Both rinse nozzles on the
assembly are identical. Use one as an inlet and the other as an outlet.
Operate the rinse water connection of the assembly with a water pressure of 2 to
max. 6 bar (29 to 87 psi). In addition, install a non-return valve and a dirt trap (100 µm)
in the water supply line (at the inlet to the assembly).
"
Caution!
If it is possible for the water pressure to rise above 6 bar (87 psi, including any transient
pressure surges), install a pressure reducing valve upstream. Otherwise the assembly
may be damaged.
Besides water, other or additional cleaning solutions may be used in the rinse chamber.
Pay attention to the material resistance of the assembly and comply with the maximum
permitted temperatures and pressures.
