1.1 Safety symbols

#Warning!

This symbol alerts to hazards. Disregard may cause serious injuries to persons or

damage to equipment.

"Caution!

This symbol alerts to possible malfunction due to operator error. Disregard may cause

damage to equipment.

!Note!

This symbol indicates important items of information.

1.2 Intended application

The immersion and process assembly DipFit W CPA 111 is suitable for universal use

in waste water / water treatment as well as process applications. It can be used in

pressures of up to 4 bar.

The bayonet mounting technique of the electrode holder permits the electrodes to be

removed and installed quickly and conveniently.

The chemical electrode cleaning system Chemoclean can be integrated without

modifying the assembly if one of the three electrode mounting positions is free.

All required accessories are available:

•Wet bucket

•KCl reservoir

•Calibration cap

•Mounting frame

•Pendulum frame

•Adapter for adjustable flange

•Spray cleaning.

1.3 Installation, start-up, maintenance

#Warning!

•The assembly may only be installed, commissioned and serviced by properly trained

personnel authorised by the system operator.

•The personnel must be familiar with these operating instructions and must adhere to

the instructions contained therein.

•Damaged assemblies that may be dangerous must not be operated and should be

clearly identified as being defective.

•Any troubleshooting of the assembly and complete measuring system is to be

performed exclusively by authorised, trained personnel.

•If faults cannot be remedied, the assembly must be removed from service and

secured to prevent accidental start-up.

•Maintenance work not described in these operating instructions may only be

performed at the manufacturer’s works or by the Endress+Hauser service

organisation.

1.4 Operational security

The assembly has been designed for safe operation according to the state-of-the-art

in engineering and according to current regulations and European standards (see

“Technical data”). It has left the manufacturer’s works in perfect condition.

However, if used improperly or for purposes other than the intended purpose, it may be

dangerous, e.g. due to incorrect installation or incorrect operating conditions.

#Warning!

•Operation in any way other than as described in these instructions may compromise

the safety and function of the measuring system and is therefore impermissible.

•The notes and warnings in these operating instructions must be strictly adhered to.

Notes for installation in pressurized systems

#Warning!

•The maximum operating pressure of the assembly must not be exceeded.

•The system must be depressurized before installation or removal of the assembly.

•Couplings and lines must be checked for leakage and damage at regular intervals.
