1Safetyinstructions

1.1 Designated use

The manually or pneumatically operated retractable assembly Cleanfit COA 451 is

designed for installing oxygen sensors in tanks and pipes.

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, therefore, 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, electrical connection, commissioning, operation and maintenance of the

measuring system must only be carried out by trained technical personnel.

The technical personnel must be authorised for the specified activities by the system

operator.

•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 for

correctness. 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 authorised 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 Endress+Hauser service organisation.

1.3 Operational safety

The assembly has been designed and tested according to the state of the art and left

the factory in perfect functioning order.

Fig. 6: Permissible and impermissible sensor installation positions

1 Ascending pipe, best position

2 Horizontal pipe, sensor top down, impermissible due to air cushion or foam bubble forming

3 Horizontal pipe, installation with permissible emitting angles (acc. to sensor version)

4 Overhead installation, impermissible due to missing electrolyte contact of the sensor electrodes

5 Down pipe, impermissible

Note!

•Do not install the assembly at places, where air cushions or foam bubbles can be

formed or where suspended particles can settle on the sensor optics (→Fig. 6).

•Measuring errors can occur, if:

– the sensor is not immersed into the medium

– suspended particles are settled on the sensor membrane

– the sensor is installed overhead.

3.3.2 Installing the assembly into the process

Move the assembly into the "Service" position (outer sleeve inserted in the assembly)

and secure the assembly to the tank or the piping using your selected process

connection.

Note!

Depending on the process connection, please observe the following:

•Check the installation of the flange seal between the flanges.

3.3.3 Rinse water connection (optionally)

You can rinse the sensor in the Service position with a second ball valve for the rinse

chamber (see Accessories).

Connect the rinse water pipe to the designated rinse nozzle. Both rinse nozzles on the

assembly are identical. Use one as an inlet and the other as an outlet.

Operate the rinse water connection of the assembly with a water pressure of 2 to

max. 6 bar (29 to 87 psi). In addition, install a non-return valve and a dirt trap (100 µm)

in the water supply line (at the inlet to the assembly).

Caution!

If it is possible for the water pressure to rise above 6 bar (87 psi, including any transient

pressure surges), install a pressure reducing valve upstream. Otherwise the assembly

may be damaged.

Besides water, other or additional cleaning solutions may be used in the rinse chamber.

Pay attention to the material resistance of the assembly and comply with the maximum

permitted temperatures and pressures.
