Safety instructions

1 Safety instructions

1.1 Designated use

The flow assembly has been designed for the installation of the membrane covered chlorine sensors CCS120, CCS140, CCS141, CCS240, CCS241 and CCS142D. Additionally, there are two more installation positions for the installation of sensors with Pg 13.5 and installation length 120 mm (4.72 inch), e.g. pH resp. ORP sensors. Its mechanical design permits its use in pressurised systems (see "Technical data").

Any other use than the one described here compromises the safety of persons and the entire measuring system and is not permitted. The manufacturer is not liable for damage caused by improper or non-designated use.

1.2 Installation, commissioning and operation

Please note the following items:

• Installation, commissioning, operation and maintenance of the measuring system must only be carried out by trained technical personnel. Trained personnel must be authorized for the specified activities by the system operator.

• Electrical connection must only be carried out by a certified electrician.

• Technical personnel must have read and understood these Operating Instructions and must adhere to them.

• Before commissioning the entire measuring point, check all the connections. Ensure that electrical cables and hose connections are not damaged.

• Do not operate damaged products and secure them against unintentional commissioning. Mark the damaged product as being defective.

• Measuring point faults may only be rectified by authorized and specially trained personnel.

• If faults can not be rectified, the products must be taken out of service and secured against unintentional commissioning.

• Repairs not described in these Operating Instructions may only be carried out at the manufacturer’s or by the service organization.

1.3 Operational safety

The assembly has been designed and tested in accordance with the latest industry standards and left the factory in perfect functioning order. Relevant regulations and standards have been met.
