#Warning!
Risk of injury!
Before starting maintenance work on the assembly, make sure that the process line and the tank are
depressurized, empty and rinsed.
Move the assembly to the "Service" position.
5.1 Cleaning the assembly
All parts in contact with the medium, e.g. the sensor and the sensor holder, must be cleaned at
regular intervals. Remove the sensor1).
• Remove light dirt using suitable cleaning agents (see chapter "Cleaning agents").
• Remove severe fouling with a soft brush and a suitable cleaning agent.
• Remove persistant fouling by soaking in a liquid cleaner and if neccessary by cleaning with a soft
brush.
!Note!
Lubricate dry O-rings, especially the O-rings of the sensor holder, to guarantee safe sealing of the
assembly.
5.2 Cleaning the sensor
You have to clean the sensor:
• before every calibration
• regularly during operation
• before being returned for repair
You can remove and clean the sensor manually or perform an automatic cleaning operation2) via the
rinse connection.
!Note!
• Clean ORP electrodes only mechanically and with water, do not use any chemical cleaning
agents. These cleaning agents apply a potential to the electrode that takes several hours to decay.
This potential causes measuring errors.
• Do not use any abrasive cleaning agents. This can lead to irreparable damage of the sensor.
• After cleaning the sensor, rinse the rinse chamber of the assembly with copious amounts of water
(possibly distilled or de-ionized). Otherwise, remaining residues of cleaning agent can corrupt
measurement.
• If required, re-calibrate after cleaning.
1) in reverse sequence of operations to the installation procedure
2) with the corresponding assembly equipment only

5.3 Cleaning agents
The selection of the cleaning agent is dependent on the degree and type of contamination. The most
common contaminations and the suitable cleaning agents are listed in the following table.
"Caution!
Do not use organic solvents containing halogen or acetone. These solvents could destroy plastic
components of the assembly or the sensor and are suspected carcinogens.
Type of contamination Cleaning agent
Greases and oils Hot water or tempered substances containing tensides (alkaline)1)
or water-soluble organic solvents (e.g. ethanol)
1) do not use for Tophit ISFET sensors! Instead, use commercially available acidic cleaning agents for the food industry
(e.g. P3-horolith CIP, P3-horolith FL, P3-oxonia active).
Calciferous deposits, metal hydroxide deposits,
lyophobic biological deposits
Approx. 3% hydrochloric acid
Sulphide deposits Mixture of 3% hydrochloric acid and thiocarbamide (commercially
available)
Protein deposits Mixture of 3% hydrochloric acid and pepsin (commercially
available)
Fibers, suspended substances Water under pressure, poss. with surface-active agents
Light biological deposits Water under pressure
