1 Safety instructions
1.1 Designated use
The manually or pneumatically operated retractable assembly Cleanfit P CPA472 is designed for
installing pH/redox sensors in tanks and pipes.
Its mechanical design permits its use 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, 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, commissioning, operation and maintenance of the measuring system must only be
carried out by trained technical personnel.
The technical 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 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 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 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.
Relevant regulations and European standards have been met.
As the user, you are responsible for complying with the following safety conditions:
• Installation instructions
• Local prevailing standards and regulations.
1.4 Return
If the assembly has to be repaired, please return it cleaned to the sales center responsible.
Please use the original packaging, if possible.
Please enclose the completed "Declaration of contamination" (copy the second last page of these
Operating Instructions) with the packaging and the transportation documents.
No repair without completed "Declaration of contamination"!

3.1 Incoming acceptance, transport, storage
• Make sure the packaging is undamaged!
Inform the supplier about damage to the packaging. Keep the damaged packaging until the matter
has been settled.
• Make sure the contents are undamaged!
Inform the supplier about damage to the delivery contents. Keep the damaged products until the
matter has been settled.
• Check that the scope of delivery is complete and agrees with your order and the shipping
documents.
• The packaging material used to store or to transport the product must provide shock protection
and humidity protection. The original packaging offers the best protection. Also, keep to the
approved ambient conditions (see "Technical data").
• If you have any questions, please contact your supplier or your sales center responsible.
3.2 Installation conditions
3.2.1 Notes on installation
The assembly is designed for installation on tanks and pipes. Suitable nozzles must be available for
this.
!Note!
• When using standard glass electrodes, only installation positions are permitted in which the
middle axis of the assembly lies at least at an angle of 15° from the horizontal (see diagram).
Otherwise, there will not be a reliable contact between the inner side of the pH membrane and
the inner terminal leads via the electrolytes.
• When using an ISFET Tophit sensor, there are, in principle, no restrictions for the installation
position. An installation angle of 0 to 180° is, however, recommended.

A Glass electrodes: minimum 15 ° to the horizontal
B ISFET sensors: recommended 0 ... 180 °, overhead possible (depending on sensor type)

"Caution!
• Avoid a siphon effect1) at the rinse chamber outlet when installing with inclined orientation. The
inlet to the rinse chamber must be from below.
!Note!
• The minimum diameter for direct installation in pipework is DN 80. This diameter is required so
that the assembly has sufficient distance from the pipe wall when brought into the "Measuring"
position.
• Use a flow assembly to install the assembly in smaller pipe diameters (see Accessories).
• When designing the installation nozzle, please observe the total immersion depth in operation
(sensor holder not inserted). Ensure that the sensor is always immersed in the medium during
operation (see "Dimensions").
