3. Receiving the product
3.1 Inspecting the product
• Check the received consignment for completeness.
• Check the DID for damage.
• Install as soon as possible after unpacking.
• Do not install or connect damaged products.
3.2 Transporting the product
• Before transporting the DID, empty all pipes, hoses and flow
cells, remove the sensors and pack them separately.
• Observe the permissible ambient conditions. See section
.
• Transport the DID carefully, do not drop. Do not expose the
DID to strong impact, mechanical loads or vibrations.
• Keep the DID away from corrosive substances, vapours of
organic solvents, nuclear radiation and strong electromagnetic
radiation.
• Use the original packaging or equivalent to protect the DID
during transport.
4. Installation
4.1 Installation location
Correct installation is important for proper functioning of the DID.
• Make the DID easily accessible for all tasks.
• Provide sufficient space for all components of the DID.
• Avoid external interferences, such as electric and electro-
magnetic interferences by leakage current, earth fault of
pumps, electric motors, high voltage currents.
• Protect the DID from direct sunlight and rain.
• Provide a reliable power supply for the control unit.
See also section
and the manual "Sensors
V1".
4.2 Installation of the DID
DID with flow cell
All parts of the DID with flow cell are assembled on a mounting
plate with pre-drilled holes for quick and easy installation.
• Use spacers (min. 10 mm) for installation of the DID with flow
cell on a flat wall.

.
DID with sensor for tank immersion
The CU 382 control unit of the DID with sensor for tank immersion
can be mounted directly on a wall. See also sections
and
.
4.3 Hydraulic connection
See also the labels on the mounting plate as well as the sections
.
The maximum flow through the flow cell of the DID is limited by
the integrated flow restrictor.
Use a vented outlet or a pressure-loading valve to avoid siphon
effect. Do not install a shut-off valve in the outlet line.
WARNING
Electric shock
- Switch off the power supply before connecting the
power supply cable and relay contacts.
- Do not dismantle the control unit.
- Installation and connection of the device and the

chemicals or pathogenic germs, wear protective
clothing and take all necessary precautions to
prevent endangering your health when installing or
dismantling the DID.
Modification of the DID is strictly prohibited.
WARNING
Electric shock
- Switch off the power supply before installation.
