Maintenance
IMPORTANT
• Service the sensor regularly to avoid overdosing within a
control system, due to incorrect measured value.
• Observe the current national regulations for maintenance
intervals.
• Do not touch the electrodes or allow them to come into
contact with greasy substances.
• Never attempt to clean the membrane with acid/alkaline
solutions, cleaning reagents or mechanical aids (brushes
or similar).
Potable, industrial, process and cooling water depending on the specific
conditions (1-4 weeks)
swimming pools: weekly
spa pools (whirlpools): daily
Check the sensor regularly for dirt, algae and air bubbles. As far as
possible, avoid contamination of the membrane with solid particles,
deposits etc. Eliminate air bubbles by increasing the flow rate.
Check the displayed sensor value on the controller regularly according to
the DPD-4 method using an appropriate chlorine measurement kit.
If necessary, recalibrate the sensor (see Chapter 8.2 "Calibration").
If calibration cannot be carried out properly, the membrane cap must be
replaced and calibration must be repeated (see Chapter 6 "Assembly",
8.1 "Run-in time" and 8.2 "Calibration").
