The sensors are installed directly via the process connection thread NPT ½" or ¾" or clamp 1 ½". As an option, the sensor can also be installed using a commercially available T­piece or cross fitting or using a flow assembly.
NOTICE
Incorrect mounting or disassembly
The Memosens head could become loose and fall off, resulting in total sensor failure
Only mount the sensor via the process connection.
To do so, use a suitable tool, such as an open-ended wrench.

Ensure that the electrodes are fully immersed in the medium during measurement. The immersion depth must be at least 35 mm (1.38"). If the sensor is being used in the ultrapure water range, you must work under air-evacuated conditions. Otherwise the CO

in the air can dissolve in the water and its (weak) dissociation can increase the conductivity by up to 3 µS/cm.

Ensure that the electrodes are fully immersed in the medium during measurement. If the sensor is being used in the ultrapure water range, you must work under air-evacuated conditions. Otherwise the CO2 in the air can dissolve in the water and its (weak) dissociation can increase the conductivity by up to 3 µS/cm.
4.1.3 CLS21D Clamp connection
Both sheet-metal brackets and solid brackets can be used to secure the sensor. Sheet­metal brackets have a lower dimensional stability, uneven bearing surfaces causing point loads, and sometimes sharp edges that can damage the clamp. We recommend you only use solid brackets due to their higher dimensional stability. Solid brackets can be used over the entire pressure/temperature range (see pressure-temperature ratings).

NOTICE
Mechanical twist protection for CLS15D and CLS21D
If too much force is applied to the Memosens head, this can shear the connections and therefore destroy the sensor
There is no need to exert excessive force when connecting the sensor to the cable coupling. Always connect the sensor gently.
If the Memosens coupling clearly will not close, check the coupling for dirt or mechanical damage and make sure you are turning in the right direction. Pay attention to the lock symbol on the coupling.
Use another Memosens cable if necessary.
5.3 Ensuring the degree of protection
Only the mechanical and electrical connections which are described in these instructions and which are necessary for the required, designated use, may be carried out on the device delivered.
Exercise care when carrying out the work.
Otherwise, the individual types of protection (Ingress Protection (IP), electrical safety, EMC interference immunity) agreed for this product can no longer be guaranteed due, for example, to covers being left off or cable (ends) which are loose or insufficiently secured.
5.4 Post-connection check
Device condition and specifications Notes
Are the outside of the sensor, assembly, cable undamaged? Visual inspection
Electrical connection Notes
Are the installed cables strain-relieved and not twisted?
Is a sufficient length of the cable cores stripped, and is it positioned in the terminal correctly?
Check the fit (by pulling gently)
Are all the screws terminals properly tightened? Tighten
Page 20
Commissioning Condumax CLS15D/16D/21D

Device condition and specifications Notes
Are all cable entries mounted, tightened and leak-tight? For lateral cable entries, make sure the cables
loop downwards to allow water to drip off
Are all cable entries installed downwards or mounted laterally?
6 Commissioning
Before first commissioning, check if:
• the sensor is correctly installed
• the electrical connection is correct.
If using an assembly with automatic cleaning, check that the cleaning medium (e.g. water or air) is connected correctly.
L
WARNING
Escaping process medium
Risk of injury from high pressure, high temperatures or chemical hazards
Before applying compressed air to an assembly with cleaning facility, make sure the connections are correctly fitted.
Do not install the assembly in the process if you cannot make the correct connection reliably.
7 Maintenance
L
CAUTION
Corrosive chemicals
Danger of chemical burns to the eyes and skin. Danger of damage to clothing and equipment
It is absolutely essential to protect the eyes and hands properly when working with acids, bases and organic solvents!
Wear protective goggles and safety gloves.
Clean away splashes on clothes and other objects to prevent any damage.
Pay particular attention to the information provided in the safety data sheets for the chemicals used.
L
WARNING
Hydrofluoric acid and mineral acids
Risk of serious or fatal injury from caustic burns
Wear protective goggles to protect your eyes.
Wear protective gloves and appropriate protective clothing.
Avoid all contact with the eyes, mouth and skin.
If using hydrofluoric acid, only use plastic vessels.

WARNING
Thiocarbamide
Harmful if swallowed. Limited evidence of carcinogenicity. Possible risk of harm to the unborn child. Dangerous for the environment with long-term effects.
Wear protective goggles, protective gloves and appropriate protective clothing.
Avoid all contact with the eyes, mouth and skin.
Avoid releases into the environment.
Clean away fouling on the sensor as follows depending on the type of fouling:
1. Oily and greasy films: Clean with grease remover, e.g. alcohol, as well as hot water and (alkaline) agents
containing surfactants (e.g. dishwashing detergent).
2. Lime, cyanide and metal hydroxide buildup and low solubility organic buildup: Dissolve buildup with diluted hydrochloric acid (3 %) and then rinse thoroughly with
plenty of clear water.
3. Sulfidic buildup (from flue gas desulfurization or sewage treatment plants): Use a mixture of hydrochloric acid (3 %) and thiocarbamide (commercially available)
and then rinse thoroughly with plenty of clear water.
4. Buildup containing proteins (e.g. food industry): Use a mixture of hydrochloric acid (0.5 %) and pepsin (commercially available) and then
rinse thoroughly with plenty of clear water.
5. Readily soluble biological buildup: Rinse with pressurized water.
After cleaning or regeneration, you must rinse the sensor thoroughly with water and then recalibrate it.
8 Repair
8.1 Sealing ring replacement and recalibration (CLS16D only)
Intact seals are a prerequisite for safe and reliable measurements. The seal should be replaced at regular intervals to guarantee maximum sensor operational safety and hygiene.
Practical repair intervals can only be determined by the user as they depend greatly on the operating conditions, such as:
• Type and temperature of the product
• Type and temperature of the cleaning agent
• Number of cleanings
• Number of sterilizations
• Operating environment
Page 22
Repair Condumax CLS15D/16D/21D
22 Endress+Hauser
Recommended intervals for seal replacement (reference values)
Application Window
Media with temperatures from 50 to 100 °C (122 to 212 °F) Approx. 18 months
Media with temperatures < 50 °C (122 °F) Approx. 36 months
Sterilization cycles, max. 150 °C (302 °F), 45 min. Approx. 400 cycles
To ensure your sensor is operational again after being exposed to very high loads, you can have it regenerated in the factory. In the factory, the sensor is fitted with new seals and recalibrated.
Please contact your sales office for information on replacing the seal and recalibration in the factory.
8.2 Return
The product must be returned if repairs or a factory calibration are required, or if the wrong product was ordered or delivered. As an ISO-certified company and also due to legal regulations, Endress+Hauser is obliged to follow certain procedures when handling any returned products that have been in contact with medium.
To ensure swift, safe and professional device returns, please read the return procedures and conditions at www.endress.com/support/return-material.
8.3 Disposal
The device contains electronic components and must therefore be disposed of in accordance with regulations on the disposal of electronic waste.
Observe the local regulations.

9.2 Performance characteristics
9.2.1 Uncertainty of measurement CLS15D
Each individual sensor is factory-measured in a solution of approx. 5 μS/cm for cell constant
0.01 cm-1 or approx. 50 μS/cm for cell constant 0.1 cm-1 using a reference measuring system traceable to NIST or PTB. The exact cell constant is entered into the quality certificate supplied. The uncertainty of measurement in determining the cell constant is 1.0 %.
CLS16D
Each individual sensor is factory-measured in a solution of approx. 5 μS/cm using a reference measuring system traceable to NIST or PTB. The exact cell constant is entered into the quality certificate supplied. The uncertainty of measurement in determining the cell constant is
1.0 %.
CLS21D
Each individual sensor is factory-measured in a solution of approx. 5 mS/cmusing a reference measuring system traceable to NIST or PTB. The exact cell constant is entered into the quality certificate supplied. The uncertainty of measurement in determining the cell constant is
