Commissioning - Notices
Before the device can be commissioned, the following measures must be implemented. You can find the position of the parts
listed in the following under Item 4.4 Device description.
6.1
Control parameters
The device is loaded with factory-defined control parameters; see Commissioning protocol on page 25/29. Please adjust the
control parameters for your basin according to the required dosing performance and the desired set points. The factory setting for
the dosing performance is 100%, which should be sufficient for an outdoor pool of approx. 100 m³.
Tip
Parameter changes are saved to the SD card with a time delay. This can take up to two minutes. If the voltage supply
is interrupted prior to the backup on the SD card, the device continues to control using the values prior to the change.
That means, if a voltage interruption occurred shortly after a parameter change, the changed parameters must be
checked again and be readjusted, if necessary!
The newly determined adjustment values are also saved to the SD card with a time delay.
6.2
pH electrode
Remove the pH electrode from the packing box and pull off the protective cap. Remove the electrode cable’s union nut from the
electrode by twisting it to the left and screw the electrode into the measuring cell from above. Subsequently, the electrode plug
must be placed back onto the pH electrode and the union nut must be tightened.
Tip
Following a temperature adjustment and inflow time of approx. one hour, it should be checked whether the pH
electrode needs to be calibrated. For this purpose, the pH electrode must be unscrewed from the measuring cell
once again and be placed in the pH7 buffer solution. If the display value shows a deviation larger than 0.1pH, a
calibration must be conducted.
6.3
Cleaning beads
The enclosed blue glass beads serve for cleaning the redox electrode's platinum surface. Pull the cable from the redox electrode
and unscrew the electrode from the measuring cell. Place approx. 15 of the enclosed blue cleaning beads on the platinum surface
so that this area is covered. Screw the redox electrode back into the measuring cell and plug the cable's black plug back into the
electrode.
When screwing in the redox electrode, ensure that no glass beads are present in the thread.
ATTENTION!
Please ensure that all hose screw connections of the measuring water pipes are firmly tightened. Check all screw
connections at the device and at the two measuring water ball valves ½“. Plastic screw connections may only be
fastened hand-tight!
6.4
Measuring cell flow
Once all electrodes have been screwed hand-tight into the measuring cell and the measuring water pipes have been connected,
the ball valves may be opened. The measuring cell flow volume can be adjusted at the flow control valve. The flow mounting float
must be pushed toward the top in order to release the dosing. In order to keep the redox electrode clean, the cleaning beads must
rotate on the platinum surface, but they must not be allowed to lift off of the platinum surface.
6.5
Dosing cartridges
Push the two dosing cartridges onto the motor shaft.
6.6
Chemicals
Place the two chemical containers under the device. In order to protect the floor, it is recommended to place the containers in a
protective tray. Please observe the proper positioning of the container;
o
red
o
pH value regulation chemical on the left and
o
yellow
o
disinfection chemical on the right.
ATTENTION!
Please do not use hydrochloric acid for the pH value regulation. Hydrochloric acid diffuses through the dosing hose
and corrodes the dosing motor. This, in turn, causes premature wear and tear of the dosing pump.
