2. Open the sampling valve.
 The medium is discharged via the outlet line.
At a prepared workstation (e.g. with collection basin or drain):
1. Disconnect the assembly from the process connection.
2. Remove the assembly from the wall bracket.
3. Open the inlet and outlet valves, sensor slots and sampling valve at the prepared
workstation.
 Collect the escaping liquid in an appropriate manner.
The amount of liquid remaining in the assembly depends on the module version.
Depending on the module version, draining allows the liquid content in the assembly to be
reduced to the following experimentally determined values:

9.2.3 Flush
Depending on the process medium, flushing is necessary to minimize or eliminate possible
chemical hazards.
Prior to rinsing, the assembly must be taken out of operation (→  34) and drained
(→  34).
Rinsing can be performed safely at different locations or in different ways:
At the installation site:
1. Connect line for rinsing medium to the inlet module of the assembly.
2. Open the inlet and outlet valves.
3. Carry out rinsing.
4. Channel the rinsing medium into the usual outlet.
The flow rate of the rinsing medium must not exceed the assembly specifications.
At a prepared workstation (e.g. with collection basin or drain):
1. Connect a rinsing line to the inlet module of the drained assembly.
2. Open the inlet and outlet valves.
3. Rinse the assembly.
4. Collect the escaping liquid.
9.2.4 Cleaning the assembly and sensors
Clean the assembly and sensor regularly as required. The frequency and intensity of
cleaning depend on the medium. Cleaning of the surfaces of the assembly and sensors in
contact with the medium can be performed manually or automatically (→  21).
