Programming And Adjusting Of The Ph Probe And The Inorganic Chlorine Cell - Astralpool POOLWATCH BASIC pH/Cl inor 16647 Manual De Instrucciones

7. PROGRAMMING AND ADJUSTMENT OF THE pH PROBE AND THE INORGANIC CHLORINE CELL
Before switching on the PoolWatch Basic pH/Inorganic Chlorine it is recommended to have the water in the pool box between
7-7.6 pH units and between 1-1.5 ppm of the free residual Chlorine (DPD nº1).
1.- Put the starter command of the dispenser pump in 0 position (off).
2.- Keep closed the inlet and outlet valve water to the analysis chamber.
3.- Take the pH electrode out of its original container.
4.- Connect the pH electrode to the wire connector on the left (corresponding to the connector 26 blue heald (-) and 27 active (+)
translucent.
5.- Fill the jug to calibrate with buffer solution pH 7. Put the buffer solution in the inferior part of the electrode. Follow the signal flow
graph planning of the equipment (pages 16-18). Go to adjustment and select the pH parameter. Introduce "SENSOR pH" and press
"ENTER". Some bars will appear on the LCD screen. Once the calibration is finished, the sentence "STABLE READING" will appear on
screen. We will press validate (VAL), which will confirm a correct adjustment of the pH electrode.
6 .- Rinse the pH electrode with buffer solution pH 4 before doing the adjustment pH 4.
7.- Fill the jug to calibrate with buffer solution pH 4. Do the same as before but using buffer solution pH 7.
8.- Take out the electrode from the jug to calibrate; throw all the content out and put the electrode in the location zone which is to the left
of the analysis chamber, switching it off from the wire connection and switching it on once it is located in the analysis chamber.
9.- Remove the Inorganic Chlorine cell from its original container. Put the Inorganic Chlorine cell (15) in the zone (B) of the analysis
chamber (A). Unscrew the lid of access to zone (B). Two parts form this lid: a fixing thread and a lid. Take the fixing thread, put it
through the wire extreme (9) of the Inorganic Chlorine cell and proceed to wind the cell in its location.
10.- Open the output and input water valves to the analysis chamber.
11.- Leave the water run through the interior of the analysis chamber during 1/2hour.
12.- Immediately after, connect the Inorganic Chlorine cell and wait 90 minutes to achieve enough bias voltage. Afterwards, make the
Chlorine adjustment with DPD-1 photometer, according to signal flow graph (page 16).
13.-Connect the Inorganic Chlorine cell in the grid following connectors.
Heald (Blue) 24 (negative), Active (Translucent) 25 (positive)
You will see the following on the LCD screen:
Superior part: Reading of the pH and planned set point. The arrow appearing on the right margin shows whether a reducer ( ) or a
increaser ( ) is being used.
Inferior part: Reading of Inorganic Chlorine and the programmed set point. The arrow appearing on the right margin shows the
disinfectant addition. ( ).
If it is a stable value, the parameter can be introduced by hand; hence we will correct the deviation from the temperature reading. A
temperature sensor can also be added (version 16648), the PT-100 with its corresponding electronic sheet. Then we will have an
automatic self-adjustment with the pH reading.
pH PROGRAMMING
1.- The PoolWatch Basic pH/Inorganic Chlorine equipment is tested with an adjusting value can be modified (see pages 16).
2.- The pH value adjustments are between 0.0 and 14, being the ideal value 7.20.
3.- The equipment has the option of lowering the pH, using a reducer or increasing the pH, using a enhancer. To do this, look at the
signal flow graph. The equipment is already manufactured to ration the pH reducer.
4.- Switch on the pH adjuster dispenser pump. Do this choosing a percentage in the pump flow volume; this must be suitable to the pool
characteristics. Once the pH is adjusted to 7.20, we will proceed to the Chlorine programming.
