Blind plug
2. Connect the Rp 1/2" hose adaptor fittings to the inlet and the
outlet.
– The Rp 1/2" hose adaptor fittings are included in the
standard delivery of the DID.
3. Assemble the inlet and the outlet hose as follows:
– Push union nut and tensioning ring across the hose.
– Push the cone part fully into the hose, see fig.
.
– Attach the cone part with hose to the adaptor fitting.
– Tighten the union nut manually. Do not use tools.

Connecting the inlet hose
Avoid high loads caused by long or heavy hoses hanging from the
outlet port of the flow cell. A strain-relief for the outlet hoses may
be required.
4.4 Installing the sensors
All sensors used in the DID are packed separately to avoid
damage. They have to be prepared before installation according
to the "Installation" section in the manual "Sensors V1" supplied
with the sensor.
• For installation of the sensors in the flow cell, see the manual
"Sensors V1" supplied with the sensors.
• As soon as the sensors are ready for operation, they must be
wetted.
• Sensors equipped with electrolyte and membrane cap must
remain powered.
4.5 Checking the tightness
1. Carefully open the inlet valve and check for any leakage of the
flow cell assembly.
2. Check if any air bubbles are visible within the hose.
3. Purge the bubbles out by temporary increase of the flow.
5. Starting up the product
5.1 Initial startup
1. Connect all sensors to the CU 382 control unit. See also
section
6.2 Connecting the sensors to the CU 382 control unit
.
2. Slowly open the inlet valve.
3. Check the hydraulic system of the DID for leakages.
6. Electrical connection
6.1 Terminal connection
6.1.1 Connecting the terminals
1. Remove the two cross-head screws on the terminal
compartment of the CU 382 control unit.
