CF Control 100
11 Maintenance and servicing
The CF Control 100 is easy to maintain, but should be checked and serviced at
regular intervals by a trained technician.
Please observe the following information on maintenance and servicing of the CF
Control 100 as well as the separate manuals, e.g. for dosing pumps and probes.
If you have any further questions regarding our measuring, control and dosing
system, please contact your dinotec pool dealer or our service department.
11.1 Cleaning and calibrating the electrodes
Depending on the water quality, the electrodes (measuring probes) must be cleaned
and re-calibrated at intervals of 4-5 weeks (or more frequently, of required, e.g. in the
case of highly ferrous water or salt deposits caused by brine water). Check the
electrodes for any mechanical damage (e.g. breakage of glass) and wipe them dry
with a soft paper towel. If there is scaling on the probe surface, the probes are
immersed in our special liquid probe cleaner (0181-184-01) for about 1 minute and
then rinsed thoroughly with water.
- If the metal pin of the redox electrode shows a brown coating, the metal
pin must be cleaned with cleaning paste (0181-184-00) and rinsed
thoroughly with water. Afterwards, dry the pH electrode with a soft
paper towel. A calibration is not required in this case.
The redox electrode is wear-free, provided there is no mechanical
damage.
- Re-calibrate the pH electrode with calibration solutions pH 7 and pH 4
and reinsert it into the measuring cell.
The service life of pH electrodes depends to a high degree on operating
conditions and maintenance. The normal service life is between 1 and 2
years.The pH electrode is a wearing part.
NOTE: Deposits on the diaphragm of the pH probe can lead to malfunction (pH
value jumps); in this case the probe is to be cleaned with a liquid probe
Other acids or cleaning agents can destroy the probes.
ATTENTION: Before removing the probes, switch off the dosing and close the
utlet at the sampling points.
