1 1. What is Oxymatic? Oxymatic is a water disinfection system comprising a box carrying electrodes, which is fitted inside a pipe by pass, also a control unit. This system is based on an ecological approach to water treatment, based on ABOT (Advanced Bipolar Oxidation Technology), which is a patent protected treatment process. This technology is the outcome of more than 15 years research. It is used in water hydrolysis and copper ionisation to provide ecological water disinfection. Oxymatic is intended primarily for swimming pools, but as it s an extremely effective waterdisinfection system, it can be used for other applications: Potable water, tap water or well water Treatment of the Legionella s bacterium Irrigation and agriculture Cooling towers, etc. 2. What is Hydrolysis? Hydrolysis is the process whereby a water molecule separates out into different strains by passing an electric current through it. The main reaction of the hydrolysis process is as follows: 2 H 2 O OHˉ + H 3 O Hydroxyl ion (OHˉ) is a powerful disinfectant that will recombine in water in approximately 32 minutes if it does not come into contact with any organic matter, so that the water is neither corrosive nor harmful to health or living creatures, and can be drunk. By virtue of the technical features of this process, there will never be excessive hydroxyl that could be harmful to health or the environment. 3. What is copper ionization? Copper ionization is a process whereby a compact block of copper is broken up in a controlled manner by applying an electric current to it. Pure copper ions are produced by this process (Cu++) just as they occur in nature. A recommended concentration in a swimming pool is in the region of 0.5 mg/l (ppm). Such levels of copper will not affect the health since, according to the WHO (World Health Organization), water is potable with up to 2 mg/l copper. 4. Is it possible with Oxymatic to get an overdose in my swimming pool that is hazardous to health? No. The maximum hydroxyl producing capacity of Oxymatic is determined by the relationship between the number of plates in the electrodes installed and the electric current applied. The level 1

2 of those parameters never varies; the maximum power delivered cannot be increased, either intentionally or by accident. Nor is it possible to get an overdose through faulty installation or programming. Apart from the technical safety hard wired into the design, no overdosing is possible with this clean hydrolysis process. This is because hydroxyl ion has a short half life providing it does not come into contact with organic matter, bacteria or viruses. This characteristic means the water is non corrosive and non harmful to health, even if drunk. Regarding copper, what Oxymatic produces is ion Cu++, pure copper, which itself occurs in nature. The human body requires this type of metal (1000 µg daily is the total daily amount recommended by the EU), the same as for iron, potassium, vitamins, etc. Oxymatic is prepared so as to maintain a constant concentration of 0.5 mg/l copper in the water. This level is not harmful to health, nor to any material. The standard for potable water states that water is potable and can be drunk if its copper content is below 2 mg/l. 5. How large a flow can be treated with Oxymatic? The same flow is able to pass through an electrode carrying box as can pass through a 75 mm PVC pipe. The flow that can pass through a pipe will depend on the water flow s speed and pressure. A key feature of our system is that by equalising speed, pressure and the flow that passes through the box, the production of hydroxyl will not be affected. 6. Is there any limit to the size of swimming pool that can be treated with Oxymatic? No; there is no technical limit with regard to the volume or flow that can be treated. It can treat a volume of approximately 175 m 3 for a pool per day using one box. We can expand the system by deploying as many boxes as necessary, and thus treat any volume of water. The hydroxyl produced by each box will accumulate in order to disinfect the entire volume of the pool. 7. How do I instal an Oxymatic with two or more chambers in one pool, as a line or in parallel? For the SMART PRO 400 models, which provide two electrode carrying chambers. What needs to be kept firmly in mind is that the recirculation flow must not decrease. The inlet pipe of the chambers is 75 mm. To install two cameras, you can do it in series or in parallel; it depends on the diameter of the existing pipe where it will be installed. Pipe 90 mm or less: the two chambers in series. From 90 mm (including: all are placed in parallel) 8. How much pressure is the electrode carrying chambers able to withstand? The box is designed to withstand pressure of 20 bar. There can never be any problem, given that PVC cannot tolerate more than 16 bar. 2

The Oxymatic system will not affect alkalinity; however, low alkalinity can cause problems in adjusting the ph, greenish water pipe, and compromise the effectiveness of the purification system. An appropriate setting is between 80 and 175 mg/l. It is often necessary to increase it. To do this, use an alkalinity booster (bicarbonate of soda or carbonate). Once set, it is not usual to amend it greatly subsequently. 10. Do I need to carry out rapid impact chlorination when starting up the pool? Rapid impact treatment should be administered in order to ensure proper operation of the system, even though we use fresh mains or well water, and all appears to be in order. Yet we cannot know whether there might be algae, spores, bacteria, etc. In view of this uncertainty, it s best to do it. 11. How do I render rapid impact chlorination effective? Use rapid impact granulated chlorine for chlorination (we recommend dichloro or trichloro). Pour in using a sufficient amount in accordance with the instructions on the tin, to raise the chlorine to 10 mg/l (ppm). As an indication, fill 2 3 kg dichloro for every 50 m 3 water in practice. With recirculation running, pour half into the skimmers and distribute the remainder in the vessel. It is not necessary to dilute it. Leave filtration in place during complete replacement of the water. This will depend on the flow from the pump, but the normal time is 4 5 hours. Shut off the pump and wait 8 hours (till next day). If there are algae, rub the walls and base down with a brush. Take the base cleaner and clear any residues of algae and dirt out of the pool (so that it does not pass through the filter, nor run back into the pool). Carry out washing of the filter and rinse. Start up the system as normal. Once the chlorine concentration falls below 2 mg/l (ppm) you can use the pool. If you use dichloro, this will be within approximately 48 hours or, with trichloro, from 2 to 3 days. 12. How do I adjust and check the copper in a swimming pool? We recommend that copper in the pool should be held at around 0.5 mg/l. To achieve this, you should check the program and verify water s copper content when starting up, and for the first few weeks. Follow the steps below to do this. Measure the copper in the water when full. If there is copper, we need to take this into account when carrying out programming. The equipment leaves the factory with nominal programming for pool sizes 80, 125, 175 and 400 m 3. If your pool is a different size, you need to amend the program using the following table: 3

4 POOL VOLUME, m 3 TEMPERATURE DEGREES MINUTES/ DAY < ⁰C ⁰C ⁰C ⁰C ⁰C ⁰C 5 These times are for guidance. They may need to be increased or decreased, depending on the measurements obtained. Consult the manual to amend the program, depending on the model. 13. Problems with excessive copper: the solution: An excess of copper: with our technology, this can only come about through faulty installation, programming or control. If we find there are yellowy green or bluish stains at the joints of the gresite or in the Liner, there could be an excess of copper in the water or there has been an increase in ph and temperature, which was not checked. Solution: 1. The first thing we need to do is measure the copper in the water several times, and at different locations. If there is copper, we need to detect and correct the problem. This could be due to: Faulty installation: Cables changed (OXY ION) Incorrect programming: Too many minutes each day 2. Turn off the copper channel by programming it (refer to instruction manual) 3. Reduce the copper in the pool. This can be done in two ways: Renovate part of the pool, wash out, etc. Check and carry out daily measurements. The copper will gradually disappear. Use a metal flocculant or special copper remover. A level of copper up to 2 ppm is not harmful to health, but can cause stains. 14. How to stop copper production? Edit the program set (User, Auto Temp, etc...) and put ION in 0 minutes 15. Water temperature and purification system s hours of operation In order that your Oxymatic system will function effectively, we need to remember that the daily hours of operation are directly dependent on water temperature. The higher the temperature, the greater the number of hours of operation required. 4

5 Hours of operation will normally be as follows: Water 20ºC = 8 10 hours continuously to Water 25ºC = hours continuously to Water 28ºC = hours continuously to22.00 Water 29ºC = hours continuously to Water >30ºC = hours continuously to From 30 C or more, it is possible you may occasionally need to use a disinfectant (anti algae, hydrogen peroxide, multiple action capsules, chlorine, etc). Consult the manufacturers on a case by case basis. 16. Is Oxymatic compatible with other disinfection systems? Oxymatic is compatible with any other treatment system and with any chemical product you may wish to use. In some instances, the Oxymatic pool disinfection system fails to maintain the water correctly at the standard number of hours, and calls for additional hours of operation. This can come about through various factors, which need to be examined on a case by case basis (age of the water, alkalinity, method of constructing the pool, number of bathers, water temperature, the environment, etc). In some cases this may not be practicable in the interests of economy and energy saving, or the customer may be unwilling/unable to keep the pump running for the length of time required (over 16 hours in some circumstances). In either or both of these situations, we can reduce the hours of operation and use chemical products to counteract the shortfall of hours. 17. Can I use an algicide with Oxymatic? You can use a special anti algae based on Cationic Polymer for pools with treatment without chlorine. DO NOT USE ANTI ALGAE TREATMENTS THAT CONTAIN COPPER SULPHATE. Procedure: Programmed pump time: hours / Set copper to the minimum: 0.3 mg/l. Initial treatment: pour 1 litre anti algae into the vessel at dusk for each 50 m 3 volume of water and continue recirculation until next day the first day. For maintenance, pour ½ litre a week, using the same routine. 18. Can I use multiple action capsules? Yes: however, you must be sure NOT TO USE CAPSULES THAT CONTAIN COPPER SULPHATE. Procedure: Programmed pump time: hours / Set copper to mg/l. Place one capsule in the skimmer for every 50 m 3 volume, once a week. 19. Can I use liquid oxygen? Yes: To do this, we can fit an automatic dose measurer to inject hydrogen peroxide (liquid oxygen), controlled automatically by Oxymatic: 5

6 Procedure: You must change the program, eliminate copper, and programme the minutes to the time of day at which you wish the pump to release a dose, so as to hold the residual concentration at around 5 10 mg/l peroxide in the water. (see manufacturer notice) 20. Can I use liquid chlorine? Yes: fit an automatic dose measurer to inject liquid sodium hypochlorite, controlled automatically by Oxymatic: Procedure: There are two ways of doing this. Dosing by time: Remove the copper and programme the minutes to the time of day at which you wish the pump to release a dose, so as to hold the residual concentration at around mg/l chlorine. The minutes can be adjusted in accordance with measurements taken at the vessel. Dosing by using Redox: Instal the dosing pump and redox probe, activate the cannel and take the desired set point. Change that set point in accordance with the measurements taken in the vessel until the system is set correctly. In the case of public swimming baths that need residual dosing to satisfy official requirements, we use this system with Redox. 21. What should I do if the pool has turned murky / green, or has algae? This is caused by a lack of disinfection, which can come about through various causes. Identify the problem, carry out rapid impact chlorination and remedy the problem. To do this we need to check the equipment, electrodes, voltage, etc. to verify that everything is in order. If we find that all equipment is in order, there could be one or more causes: Hours of treatment are not commensurate with the water temperature. Hours of treatment need to be continuous. Alkalinity is too low: the correct parameters are between 80 and 175 mg/l. Poor pump recirculation and dead areas. Old and/or poorly blended water. A lot phosphate in the water 22. The alarm at the control unit has been triggered. What should I do? Press the alarm button to turn off the buzzer. When the alarm is activated, a red color light shows the channer which has the problem (ph, OXY, ION... Check the channel in each case check: high or low ph Check ph probe Correct set point OXY / ION current low and OXY / ION high voltage Lack of salt (low water conductivity) Electric cables are failing to make proper contact at the electrodes A green internal cable plug has come adrift 6

7 An internal cable has come out of its plug Electrodes are wasted away or degraded 23. How to connect electrically the Oxymatic to the electrical panel of the pool? Oxymatic plugged to the electric power. With OXYMATIC, you can do the maneuver of the recirculation pump making a by pass in the contactor coil. See diagram in manual. 24. How do I change the Oxymatic program in order to use a ph booster instead of reducer? To do this, everything is the same as for the ph reducer, except that we have to change the setpoints and place them in the ph booster flask. The set points we need to take: 0% = % = 6.8 Once it reaches 7.0, the pump will shut down and release a dose below. 25. What do I need to think about, check and correct in a pool when installing an Oxymatic? Check the existing recirculation system, type of water, the age of the water and filter: the efficiency of any disinfection system depends on these factors. Temperature that the water may reach in the summer: in order to calculate Oxymatic s hours of operation. Total salinity: to ascertain and adjust the equipment voltage. Alkalinity: Check the ph and eliminate any algae or murkiness. Copper: Program the system and avoid any overdosing. ph: must always be properly adjusted. 26. How do I check total water salinity? In order for the system to function correctly, total salinity of the water must be greater than mg/l. In order to verify this, it is necessary to set the power shown at the control unit: OXY CURRENT: Smart 80 model: 8 A Smart 125 model : 10 A Smart 175 model: 12 A Smart 400 model : 12 A In the event that these parameters fail to raise the salinity of the water by 100 mg/l, you need to pour 1.5 kg table salt for every 10 m 3 of pool and allow it to dissolve. In practice, a 25 Kg bag of 7

8 table salt for every 50 m 3 volume of water will be sufficient. If it fails to rise, continue pouring until the correct strength is reached. Once the salinity is set correctly, there is no need to repeat. 27. Can I install Oxymatic in a Spa, in an indoor pool or in a pool with warm water? Yes, and one of the benefits is that it does not corrode the metal parts, does not generate toxic vapors and with the OXYMATIC system, indoor pools will smell good. The only thing to consider in these facilities is to adjust the power of the system to the volume of the water and limit the redox potential to 800 mv. 28. Can it be used with hard water with encrustations problems? Yes, although the electrodes are self cleaning, when the water is very hard scale problems can appear, but much less than with any other system, since the ABOT technology has a certain descaling power in the water. 29. Can it be installed in a pool with sea water? Yes, OXYMATIC disinfects any type of water, including sea water. 30. What is the proper set point for ph? In general, we should maintain: Private pools of 6.5 to 7.6 Set Point 0% = 7.1 Set point 100% = 8.0 Public swimming pools (according to regulations): 7.2 to 8 Set Point 0% = 7.3 Set point 100% = What is the proper set point for the ORP Generally, we will keep the pool between 0,5 and 2 mg / l, Hydrover recommends between 0,5 and 1 mg / l: Public swimming pools (adjust between 0,5 and 1 mg / l) Set Point 0% = 700 mv Set point 100% = 600 mv Private swimming pools Set 0% point = 600 mv Set point 100% = 400 mv 8

9 Spas and small pools <20 m3 Set Point 0% = 700 mv Set point 100% = 400mV 32. How to adjust residual chlorine in a public swimming pool? The ORP sensor measures ORP or Redox potential of the water and measure it in mv (millivolts). This measurement corresponds to the degree of oxidation or reduction of the electron when there is a disinfectant in water. This means that the redox potential is the water disinfection capacity. We know that there is a disinfectant in the water, when there are more than 200 mv and in a pool, an optimum value of mv. ORP probes are not able to distinguish from where comes the ORP value. It may be chlorine, bromine, oxygen, or hydroxyl ions of the OXYMATIC or a mixture of all of them. This is what happens to our OXYMATIC system, the pool is filled with hydroxyl ions which give an average ORP value of mv (depending on ph, temperature, salinity and power equipment ). If we add chlorine we have to add the redox potential due to chlorine. How to configure the set points: Set the set point 0% to 700 mv Set the set point 100% to 500 mv The next day, we will measure the free chlorine residual in the pool with DPD tablets (NOT with drops) if below 0,6 mg / l, increase the set point 0% to 720 mv if greater than 1,5 mg / l, decrease to 690, if between 0,6 and 1 mg / l, leave it as it is So every day until the pool is stabilized and it has the residual chlorine level we want. 33. What is the effect of urine on OXYMATIC? Chlorine causes a reaction on contact with urine, which are unpleasant chemical irritants which give the characteristic odor of chlorine in water, they are called chloramines (combined chlorine) and trihalomethanes. OXYMATIC generates hydroxyl ions that eliminate viruses, organic matter, bacteria, algae and urine elements without producing side effects. This means that hydrolysis does not generate unpleasant by products in the water. 9

10 34. Which Peristaltic pump do I need to regulate ph and chlorine in my pool? If the pool is 250 m3: peristaltic pump 1.5 l / h If the pool is 250 m3: variable peristaltic pump 1,5 7 l / h 36. The control unit does not pick up WI FI: Place a WIFI signal repeater in the engine room. 37. The device switches on and off continuously Put the machine in manual mode for a minimum of 5 hours and then put it in automatic mode. If the problem persists, contact the manufacturer. 10
