WARNING: Electrical hazard.
Failure to comply with these instructions can result in serious injuries or death.

THE EQUIPMENT IS INTENDED TO BE USED ONLY IN SWIMMING POOLS

WARNING

  • Carefully read the instructions that appear in this manual and on the device. Failure to comply with the instructions can cause injuries. This document must be given to every pool user, who should keep it in a safe place.
  • Disconnect the equipment from the mains supply before any intervention.
  • All electrical connections must be carried out by a qualified approved electrician in accordance with the standards currently in force in the country of installation or, failing this, in accordance with the international standard IEC 60334-7-702.
  • Check that the device is plugged into a power outlet that is protected against short-circuits. The  device must also be powered via an isolating transformer or a residual current device (RCD) with a nominal operating residual current not exceeding 30 mA.
  • Ensure that children cannot play with the device. Keep your hands and any foreign object away from openings and moving parts.
  • Check that the supply voltage required by the product corresponds to the voltage of the distribution network and that the power supply cables are suitable for the product power supply.
  • Chemicals can cause internal and external burns. To avoid death, serious injury and/or damage to equipment, wear personal protective equipment (gloves, goggles, mask, etc.) when servicing or maintaining this device. This device must be installed in an adequately ventilated place.
  • The unit shall not be operated when there is no water flow in the cell.
  • To reduce the risk of electric shock, do not use an extension cable to connect the device to the mains. Use a wall socket.
  • Use, cleaning or maintenance of the device by children over 8 years of age or by people with impaired physical, sensory or mental capacities, or a lack of experience or expertise, should only take place once they have received appropriate instruction and under adequate supervision of an adult who is responsible for them, to ensure the device is handled safely and avoid all risk of danger.
  • Use only original Hayward® parts.
  • If the power supply cable is damaged, it must be replaced by the manufacturer, the after-sales service or similarly qualified persons to avoid danger.
  • The device must not be used if the power cord is damaged. An electric shock could occur. A damaged power cord must be replaced by the after-sales service or similarly qualified persons to avoid danger.

  1. Pool
  2. Circulation pump
  3. Acid
  4. Chlorine
  5. Filter
  6. Heat exchanger
  7. pH probe
  8. ORP probe
  9. Temperature sensor

Warning!
Use with salt chlorinator:
For the pH systems, to prevent the risk of system malfunctioning or damage, observe the following instructions:

  1. Position the pH measuring probe prior to the chlorinator cell.
  2. To eliminate eddy currents, connect the pool water to an electrical ground point
  3. Position the product injection point after the chlorinator cell.

Wall-mounted installation
Mount the control box on the wall. The box must be installed in the equipment room (dry, temperate, ventilated). Caution, acid vapours can cause irreversible damage to your device. Position the treatment product tanks accordingly.
Unplug the pool filter pump before you begin the installation. The installation must be performed in compliance with the regulations in effect in the country of installation.

Installation of pH and ORP probes, and acid dosing pump
The pH and ORP probes are «wet» packed and protected by a plastic cap. The probes must always remain wet. If the probes are allowed to dry, they will be permanently unusable (not covered by the warranty) and the pH-ORP test kit will be ineffective. Remove the pH and ORP probes from their plastic protective caps and set the caps aside for later use (wintering). Insert the probes into the double probe holder and tighten to ensure they are watertight. Connect the probe holder to the valves screwed onto the saddle clamps and tighten by hand only. Check that the probes are watertight at startup. Seal with Teflon, if required. After installation, check that the probes are constantly in contact with the water in the pool. When the filtration pump is not running (even for long periods), the water remaining in the chamber may be sufficient to protect the probes.

When the OFA time (Over Feed Alarm) is set, the dosing time of Set Point pH/ORP in time is controlled with two alarms:

  • First alarm at 70% of the time set is seen on the display, and the alarm relay closes.
  • Second alarm at 100% of the time set is seen on the display and the alarm relay closes and the pH/ORP pump is blocked.

SERVICING

During the fi rst 10-15 days, your system will require more attention:

  • Check that the pH remains at the ideal level (7.2 to 7.4).
  • If the pH is exceptionally unstable and uses a lot of acid, check the alkalinity (see table).

If the balance is highly unstable, contact your pool installer/builder.

  • REMEMBER that the system needs a certain amount of time to adapt to your pool and will require additional chemicals during the fi rst 3-5 days. The pool must be regularly maintained and the skimmer baskets emptied whenever necessary. Also check that your fi lter is not clogged.

  • DOSING PUMPS: Regularly check the acid level to ensure that the pump does not run dry. The dosing pump must be checked and serviced at regular intervals. The Santoprene tube of the peristaltic pump has a lifetime of 2 years. We recommend that you change it once a year.

  • Servicing the probe
    The probe must be clean and free from oil, chemical deposits and contamination to function properly. As it is in continuous contact with the water in the pool, the probe may need to be cleaned weekly or monthly, depending on the number of bathers and other specifi c pool characteristics. A slow response, more frequent pH calibration and inconsistent readings indicate that the probe needs to be cleaned. To clean the probe, turn off the power to the EasyChem Double. Unplug the probe connector from the control box, unscrew the probe and carefully remove it from the chamber. Clean the probe bulb with a soft toothbrush and regular toothpaste. A household washing-up liquid detergent may also be used to remove any oil. Rinse with fresh water, replace the Tefl on tape on the threads, and reinstall the probe. If the probe continues to give inconsistent readings or requires excessive calibration after it has been cleaned, it should be replaced.The lifetime of the probes is 1 year. We recommend that you calibrate them every month during the season the pool is in use.

  • Wintering
    The EasyChem Double, probe and pool piping run the risk of being damaged if the water freezes. In regions that experience long periods of cold weather, be sure to drain all the water from the pump and fi lter and from the supply and return pipes before winter. Do not remove the control box.

  • Probe storage
    The end of the probe must always be in contact with water or a solution of KCl. If it is removed from the measuring chamber, it should be stored in the plastic cap provided (fi lled with water). If the storage cap has been mislaid, the probe should be stored separately in a small glass or plastic container with its end immersed in water. The probe must always be in a frost- free environment.

Hose replacement procedure (valid for 2 and 3 rollers)

Storing the pump after use

  • When the regulation device must be stored, clean water should be pumped through the hose in order to rinse it.
  • Then position the roller at 7h05, turning in the direction indicated by the circular arrow.
  • These two precautions will facilitate the subsequent reactivation of the unit.

TROUBLESHOOTING GUIDE

No display

  • Check that the On / Off switch is on.
  • Check the connection cable between the display and the control box.
  • Check the power supply: 210-230 V ∼ 50 Hz.
  • Check the dosing method if the OFA Alarm show continuously.
  • Check the lifetime probe by calibration method.
  • Check the running pump by Priming function.
  • If the problem persists, contact your pool installer/builder.
