Page 4 of 13 EZ-CHEM Rev. B GENERAL EZ-Chem is a device for regulating the pH of your pool. With the addition of an ORP kit (optional), it can also regulate both the pH and the liquid chlorine injection to provide you with a complete treatment. EZ-Chem can treat pools up to 90 m

INSTALLATION Disconnect the pool filter pump before starting the installation. The installation must be carried out in accordance with the standards currently in force in the country. The control box must be mounted a minimum horizontal distance of 3.5 m (or more, if required by local regulations) from the pool and within 1 m of a protected outlet. Preparing the water in the pool To prepare the pool water, its chemical composition must be balanced. Certain adjustments to the chemical balance of the pool can take several hours. It is therefore necessary to start the procedure well before switching the unit on.Chemical water balance The following table summarizes the concentrations recommended by Hayward. It is important to maintain these concentrations to prevent surface corrosion or deterioration and to derive full benefit from your pool. Control your water regularly. Your authorized Hayward dealer or pool suppliers will provide you with the chemicals you need, together with instructions on how to use them, to adjust the chemical balance of the water in your pool.

CHEMISTRY RECOMMENDED CONCENTRATIONS

Free chlorine 1.0 to 3.0 ppm pH 7.2 to 7.6 Cyanuric acid (Stabiliser) 20 to 30 ppm (preferably 25 ppm) Only add stabiliser if necessary Total alkalinity 80 to 120 ppm Water hardness 200 to 300 ppm Saturation index -0.2 to 0.2 (preferably 0) Saturation index The saturation index (Si) gives us information about the calcium content and alkalinity of the water; it is a water balance indicator. Your water is correctly balanced if the Si is 0 ± 0.2. If the Si is below -0.2, the water is corrosive and the coating on the pool walls may be damaged. If the Si is above +0.2, stains may appear. Use the following table to determine the saturation index. Si = pH + Ti + Ci + Ai - 12.1 °C °F TiHardness(calcium) Totalalkalinity

Use: Measure the pH of the pool water, the temperature, the water hardness and the total alkalinity. Use the table above to determine Ti, Ci and Ai in the above formula. If the Si is equal to 0.2 or more, stains may appear. If the Si is equal to -0.2 or less, corrosion or deterioration may occur. - 0.2

• WARNING – 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. It must be installed in an adequately ventilated room. Mount the box (or both boxes if the ORP option is chosen) on the wall using the mounting kit supplied. The box must be installed in the equipment room (dry, temperate, ventilated). Caution, acid vapours and/or chlorine can cause irreversible damage to your device. Position the treatment product tanks accordingly. The flow switch must be installed on the return pipe directly in line with and upstream of the treatment product injection point. Allow a 25 cm straight section before the flow switch. A hole should previously have been drilled in the pipe to allow the flow switch to pass through. Screw the flow switch (M) into the saddle clamp (H) taking care to seal with Teflon. Then install the clamp on the pipe. The flow switch must be installed in the direction of operation to ensure that it is tripped by the flow from the filter pump. The probes must be installed on the filter outlet pipe to protect them from debris. A hole should previously have been drilled in the pipe to allow the probe to pass through. Fix the saddle clamp and install the probes in the clamp (H) with the probe (G) provided for this purpose. For the probes to operate, they must be vertical, with the cable upward. The probes must always remain wet. If the probes are allowed to dry, they will be permanently unusable (not covered by the warranty). The treatment products must be injected last over the water return line, after any equipment (heater, etc.). A hole should previously have been drilled in the pipe to allow the treatment product to pass through. Install the saddle clamp (H) and screw the injection valve (E) into the saddle clamp using the adapter (L) provided. Seal with Teflon. Connect the pH probe to the corresponding BNC connector. Connect the ORP/RedoX probe to the corresponding BNC connector (if the ORP option is chosen).
