CP42 Conductivity Probe
Safe operation of these products can only be guaranteed if they are properly installed,
commissioned, used and maintained by qualified personnel (see Section 1.11) in compliance with
the operating instructions. General installation and safety instructions for pipeline and plant
construction, as well as the proper use of tools and safety equipment must also be complied with.
Do not install the probe outdoors without additional weather protection.
Drain/vent holes must be kept clean - do not cover.
1.1 Intended use
Referring to the Installation and Maintenance Instructions, name-plate and Technical Information
Sheet, check that the product is suitable for the intended use/application.
The conductivity probe CP42 is designed for use with Spirax Sarco conductivity controllers. If
used in conjuction with other controllers then a safety power supply unit that delivers a Safety
Extra Low Voltage (SELV) must be used to supply the controller/probe.
The CP42 Conductivity probe and the BCR3250 comply with the requirements of the Pressure
Equipment Directive (PED) and carry the Mark.
The blow-down control and monitoring equipment is EU type approved according to EN12952/
EN12953. these directives state, among other things , the requirements made on limiting systems
and equipment for steam boiler plants and (pressurized) hot water applications
i) The products have been specifically designed for use on steam and water. The products’ use
on other fluids may be possible but, if this is contemplated, Spirax Sarco should be contacted
to confirm the suitability of the product for the application being considered.
ii) Check material suitability, pressure and temperature and their maximum and minimum values.
If the maximum operating limits of the product are lower than those of the system in which it
is being fitted, or if malfunction of the product could result in a dangerous overpressure or
overtemperature occurrence, ensure a safety device is included in the system to prevent such
over-limit situations.
iii) Determine the correct installation situation and direction of fluid flow.
iv) Spirax Sarco products are not intended to withstand external stresses that may be induced
by any system to which they are fitted. It is the responsibility of the installer to consider these
stresses and take adequate precautions to minimise them.
v) Remove protection covers from all connections and protective film from all name-plates, where
appropriate, before installation on steam or other high temperature applications.
1.2 Access
Ensure safe access and if necessary a safe working platform (suitably guarded) before attempting
to work on the product. Arrange suitable lifting gear if required.
1.3 Lighting
Ensure adequate lighting, particularly where detailed or intricate work is required.
