2 Basic safety instructions
2.1 Requirements for personnel
• Installation, commissioning, operation and maintenance of the measuring system may be
carried out only by specially trained technical personnel.
• The technical personnel must be authorized by the plant operator to carry out the specified
activities.
• The electrical connection may be performed only by an electrical technician.
• The technical personnel must have read and understood these Operating Instructions and
must follow the instructions contained therein.
• Faults at the measuring point may only be rectified by authorized and specially trained
personnel.
Repairs not described in the Operating Instructions provided must be carried out only
directly at the manufacturer's site or by the service organization.
2.2 Designated use
The CYR10B cleaning injector is a spray cleaning system for pH / ORP sensors as well as
oxygen and turbidity sensors. The system is based on the same principle as a Venturi water jet
pump, which is used to mix motive water and cleaning agent. The resulting mixture is used to
clean a sensor in an appropriate assembly.
Use of the device for any purpose other than that described, poses a threat to the safety of
people and of the entire measuring system and is therefore not permitted.
The manufacturer is not liable for damage caused by improper or non-designated use.
2.3 Workplace safety
As the user, you are responsible for complying with the following safety conditions:
• Installation guidelines
• Local standards and regulations
Electromagnetic compatibility
• The product has been tested for electromagnetic compatibility in accordance with the
applicable European standards for industrial applications.
• The electromagnetic compatibility indicated applies only to a product that has been
connected in accordance with these Operating Instructions.
2.4 Operational safety
Before commissioning the entire measuring point:
1. Verify that all connections are correct.
2. Ensure that electrical cables and hose connections are undamaged.
3. Do not operate damaged products, and protect them against unintentional operation.
4. Label damaged products as defective.

During operation:
‣If faults cannot be rectified:
products must be taken out of service and protected against unintentional operation.
2.5 Product safety
The product is designed to meet state-of-the-art safety requirements, has been tested, and
left the factory in a condition in which it is safe to operate. The relevant regulations and
European standards have been observed.

7 Check valve (to be provided by customer)
8 Solenoid valves
9 Water jet pump
The cleaning injector uses the Venturi principle to mix motive water and cleaner to form a
cleaning mixture.
In the process, the motive water flows through a water jet pump (injector) to the spray head.
The resulting negative pressure causes the cleaner to be sucked in and mixed with the motive
water.

Product description Chemoclean CYR10B
10 Endress+Hauser
The flow rate of motive water and cleaner is controlled by the Liquiline CM44x via two
solenoid valves in the injector.
The mixture ratio can be configured using a metering screw.→  29
Hose lines are used to supply the motive water and cleaner and to route the cleaning mixture
to the spray head.

 3 How a water jet pump works
The water jet pump installed in the injector functions without mechanical components in
accordance with the Venturi principle.
For this purpose, cross-section A1 of the motive water line within the injector is tapered in
sections to match cross-section A2.
The suction line for the cleaner is attached at the point of the narrowest cross-section. This is
where the speed of the motive water is at a maximum. The high speed induces a negative
pressure in the suction line, causing the cleaner to be sucked in and mixed with the motive
water.
The suction process causes a reduction in pressure downstream from the water jet pump.
