INSTALLATION DIAGRAM

  • It is essential to use anti-scale liquid chlorine. Any damage to the equipment due to limescale crystallisation is not covered by the warranty.
  • The pH corrector container must be kept 2 metres away from any electrical device or any other chemicals. In order for acid fumes to be expelled outside the pool house, a venting system must be placed on the pH corrector’s hermetic cap. Failure to follow these instructions may lead to abnormal oxidation of metal parts, possibly resulting in complete device failure. Personal protective equipment (glasses with side protection, suitable gloves, refer to the product’s safety data sheet) must be worn whenever handling the pH corrector or the injection circuit
  • Never use hydrochloric acid, as this may lead to irreversible damage to the device and void the warranty. Only use a sulphuric acid- or alkali-based pH corrector product recommended by your professional dealer. Please note that use of a multi-acid pH corrector requires increased maintenance, and its use may also lead to premature wear of the ph circuit and void the warranty. Refer to the product’s safety data sheet.

DETAILS ABOUT THE ORP CHECK

The amount of chlorine required can vary depending on several conditions :

  • Covered pool (by sheeting, cover or panels)
    • Low chlorine requirement (because there is no UV).
  • Sudden rise in the number of people using the pool
    • Very large amounts of chlorine needed, but on a temporary basis.
  • Indoor pool or sheltered pool
    • Reduced need for chlorine (because of low exposure to external pollution), but which tends to increase depending on the frequency of use of the swimming pool.

Given this range of possible configurations, chlorine production must be managed according to requirements. The ORP check enables you to react to each of these situations.

The ORP measurement (in mV), reflecting the oxidation (or reduction) potential of the water, is a major indicator of the pool’s water quality.
According to the WHO, an ORP measurement of 650 mV guarantees disinfected water that is itself capable of disinfecting. Despite the use of this value as a reference, this can only be on a theoretical level, because ORP measurements can easily varv depending on the following parameters:

  • The pH.
  • The type of chlorine (stabilised or non-stabilised).
  • The presence of dissolved elements that can affect the water (metals, phosphates, surfactants).
  • The cleanliness of the filter.
  • The presence of stray currents.
  • The presence of flocculant (deposit on the ORP probe).
  • The ORP measurement:
    • is not a measurement of free chlorine levels.
    • varies according to free chlorine levels and all elements in the water.

ESSENTIAL PREREQUISITES FOR AN OPTIMAL ORP CHECK :

  • Stable pH (with a pH regulator).
  • Stabiliser level between 20 and 30 ppm.
  • Earthing of the pipe where the ORP probe is installed (with a Pool Terre).
  • Balanced water profile (free chlorine levels at 1 ppm, and pH at 7.2).
  • ORP setpoint adjusted according to the ORP measurement displayed (a value between 500 and 700 mV can be considered as correct).
  • The use of sulphates is permitted, provided they remain at levels below 360 ppm.
  • The use of copper sulphates is strictly forbidden.
  • The use of borehole water is strictly prohibited.
  • When using a chemical (flocculant, waterline cleaning, sequestrant), check the ORP measurement before and after use of this product. If the ORP measurement drops sharply, stop the electronics unit for a few days, until the effects of the product on the ORP measurement disappear.
  • Influence of chloramines on the ORP measurement: as chloramine levels tend to increase, the ORP measurement tends to decrease.

The ORP check in no case eliminates the need to regularly check free chlorine levels.

Chlorine dosing

  1. Calibrating the ORP probe

    • The pH sensor must be calibrated:

    • when first commissioning the equipment.

    • at the start of each season when the equipment is re-commissioned.

    • each time the ORP probe is replaced.

      1. Open the 475 mV ORP calibration solution.
      2. Turn off the filtration (and therefore the electronics unit).
      3. If the probe is already installed :
      • a) Remove the probe from the probe holder, without disconnecting it.
      • b) Remove the probe holder nut and replace it with the stopper provided.

pH regulation

  1. Calibrating the pH probe
    The original pH probe provided is already calibrated. It is therefore not necessary to calibrate the pH probe when putting the equipment into service for the first time.
    However, the pH probe must be calibrated:

    • at the start of each season when the equipment is re-commissioned.
    • each time the pH probe is replaced.
    1. Open the pH 7 and pH 10 calibration solutions (use only single-use calibration solutions).
    2. Turn off the filtration (and therefore the electronics unit).
    3. If the probe is already installed:
    • a) Remove the probe from the probe holder, without disconnecting it.
    • b) Remove the probe holder nut and replace it with the stopper provided.
      If the probe is not already installed :
      Connect the probe to the electronics unit.
    1. Turn on the electronics unit.

  2. Important precautions regarding the peristaltic pumps

    • This chapter is applicable if the electronics unit is fitted with a cover hiding the peristaltic pump(s).
      When one of the messages below is displayed, the (or one of the two) peristaltic pump(s) is running. IN THIS CASE, DO NOT REMOVE THE COVER OF THE ELECTRONICS UNIT COVERING THE PERISTALTIC PUMP(S).
      Note for the DUO model: the 2 peristaltic pumps cannot run simultaneously .Pool-Technologie-DUO-Chlorine-Doser-by-ORP-Control-
\(41\)

    • If case of doubt about the correct functioning of one of the peristaltic pumps:

    1. Switch off the electronics unit.
    2. Remove the cover of the electronics unit which covers the peristaltic pump.
    3. Remove the internal pipe from the peristaltic pump, without removing the semi-rigid pipes connected to it. 4) Check the condition of the peristaltic pump and internal pipes.
    4. Turn on the electronics unit.
    5. Carry out a manual vacuum injection.
    6. Check that the peristaltic pump is running correctly.
