Screwing In The Potentiostatic Electrode 11 Fig; Installation Of Temperature Sensor Pt100; Installation Of Sample Water Deficiency Sensor - Grundfos AQC-D4 Installation And Operating Instructions Manual

9.4 Screwing in the potentiostatic electrode
1. Remove the protection cover of potentiostatic measuring and
reference electrode (pos. E) (green marking). Keep it for
electrode removal.
Only touch the electrode at the screwed head!
Caution
Do not touch the noble-metal ring!
2. Slide the electrode (pos. E) into the location (pos. B) at the
hole of the flow fitting (pos. F) with the noble-metal ring at the
bottom.
Fig. 9 Mounting places of electrodes
Caution
Do not tighten the electrode (pos. E)!
3. Open the measuring water inlet (pos. J).
4. Adjust the flow through the measuring block by the sample
water adjusting spindle (pos. L) so that water emerges out of
the ascending pipe (pos. G) of the integrated sample water
limitation.
5. Connect the cleaning motor (H) with the power supply.
6. Carefully screw in the electrode (pos. E) until it stops.
When screwing in the electrode (pos. E), do not
block the stone!
Caution
If the electrode is screwed in by force, the screw part
or the electrode might be damaged, instead, loosen
electrode by turning it half circle and re-screw in.
9.4.1 Installing pH and redox electrodes
See fig. 9.
1. Remove the protective caps (location A) at the flow fitting.
2. If required, screw in the pH electrode (white marking) into one
of the locations (A1/A2).
3. If required, screw in the redox electrode (red marking) into
one of the locations (A1/A2).
See instructions of the electrodes!

9.5 Installation of temperature sensor Pt100

Warning
Observe the installation and operating instructions of
the measuring amplifier!
1. Plug the temperature sensor (product number 95713140)) into
the supplied cover.
2. Put the cover with the measuring sensor into the measuring
cell at the designated location (pos. D).
3. Establish the electrical connections.
Observe the installation position!
Caution
Do not insert the temperature sensor into the
overflow hole of the sample water limitation (pos. G)!

9.6 Installation of sample water deficiency sensor

• If required, screw the sample water deficiency sensor (pos. I)
into the designated location at the measuring cell.
