Frequently Asked Questions - Easy Chem HAYWARD

How to install the pH and ORP probes?

The probes are delivered wet with a protective cap. Remove the cap and insert the probes into the double probe holder. Tighten by hand to ensure a seal. The tilt angle of the probe must never exceed 45° from vertical. Make sure the probes remain constantly in contact with the pool water.

How to perform pH calibration?

Access the calibration menu by pressing OK for 3 seconds. Select 'pH Calibration'. Follow the on-screen instructions: immerse the probe in pH 7 buffer solution, then in pH 4 (or a single point if configured). Calibration is automatic. Rinse the probe with demineralized water between solutions.

What does the 'OFA_1' or 'OFA_2' alarm mean?

OFA stands for 'Over Feed Alarm'. OFA_1 appears when the dosing duration exceeds 70% of the set time. OFA_2 at 100% blocks the pump. To reset, press OK for 3 seconds or use the exit button. Check the product levels and probe status.

How to prime the dosing pumps?

From the main menu, select 'Priming menu'. Use the ∧ or ∨ keys to choose the pH or ORP pump. Press OK to start priming. The pump will run continuously as long as you hold down the key. Release to stop.

What chemicals to use with the Easy Chem?

For pH, use an acid (pH-) or alkali (pH+) according to the configured dosing type. For ORP (chlorine), use a chlorinated product or a reducer depending on the mode (Low or High). Follow safety instructions: wear gloves and goggles, and place the reservoirs in a ventilated area.

How to clean the probes?

Turn off the device and disconnect the connectors. Unscrew the probe from the chamber. Clean the bulb with a soft toothbrush and toothpaste or a mild liquid detergent. Rinse with clean water. Dry and reassemble with new Teflon tape. Replace the probe if readings remain unstable.

The device does not turn on, what to do?

Check that the on/off switch is in the ON position. Make sure the power outlet is live (220-240 V). Check the connection cable between the screen and the unit. If the screen remains black, check the fuse (500 mA fast). If the problem persists, contact your installer.

How to set the pH set point?

From the main menu, select 'Configuration' then 'pH'. Use ∧ or ∨ to set the desired value (between 6 and 8 pH, default 7.4). Confirm with OK. You can also set the dosing type (Acid or Alkaline) and measurement alarms.

What is the lifespan of the probes and how to store them?

The probes have a lifespan of about 1 year. They must always remain wet: store them in the cap filled with water or in a KCl solution. Avoid freezing. In winter, remove the probes and keep them frost-free. Clean them regularly to extend their lifespan.

How to replace the peristaltic pump tube?

Open the pump cover. Release the left connector by pulling it upward. Turn the roller to free the tube. Place the new tube: insert the left connector, pass the tube under the guide, turn the roller to guide the tube to the right connector. Close the cover firmly. Replace the tube every year.

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.

3b. 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.

3c. 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.

4. ELECTRICAL CONNECTIONS

4a. Electrical installation and wiring

Connect the EasyChem Double to a permanent power outlet.

9. SERVICING

During the first 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 first 3-5 days.

The pool must be regularly maintained and the skimmer baskets emptied whenever necessary.

Also check that your filter 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 specific 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 EasyChemDouble.

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 Teflon 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 EasyChemDouble, 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 filter 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 (filled 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)

Cross-sectional diagram of a mechanical component with symmetrical arch and base (no text or symbols)

Open the pump's lid and release the hose by pulling the left connector upward.

Close the pump's lid and press its surface hard so that it is properly locked into place.

Storing the pump after use

Cross-sectional view of a mechanical component with no visible text or symbols

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.

10. 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.

Chech the lifetime probe by calibration method.

Chech the running pump by Priming function.

If the problem persists, contact your pool installer/builder.

11. ENVIRONMENTAL INFORMATION
