1 Safety instructions
1.1 Designated use
The manually operated retractable Cleanfit W CPA450 is intended to allow installation of pH/ ORP
and oxygen sensors in tanks and pipelines while the system is in operation.
Thanks to its design, the assembly can be used in pressurized 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.

3.2.2 Installation notes
Suitable sensors
The following sensors are suitable for installation in the CPA450:
• Digital sensors with Memosens technology, length 120 mm / 4.72"
• pH/ORP glass electrodes, length 120 mm / 4.72"
• ISFET sensors: only sensors listed in "Accessories" chapter
• DO sensors, length 120 mm / 4.72"
• For the conductivity sensor CLS15 a modification is available
Installation positions
The permissible installation angle of the assembly depends on the sensor:
• Glass electrodes and digital sensors with Memosens technology:
Install the assembly at an angle of at least 15° from the horizontal (see Fig. 3).
•ISFETsensors:
When using an ISFET sensor, there are, in principle, no restrictions to the installation. An
installation angle between 0° and 180° is, however, recommended.
a0005327
Fig. 3: Installation angle of the assembly
A Glass sensors: 15° to horizontal
B ISFET sensors 0 to 180° recommended
Install the assembly so that the sensor is kept wet at all times.
