SALT CHLORINATOR GENERATOR USER MANUAL

PTGEM SALT WATER CHLORINATION EQUIPMENT

Thank you for purchasing PTGEM salt water chlorinator generator, which will enable you to enjoy your swimming pool in perfect conditions, without the need to add any chemical disinfectants.

The PTGEM salt water chlorination generator system produces chlorine directly in the filtering installations by means of electrolysis of slightly salted water. “Free chlorine” (Hypochlorous acid, HClO) is produced which is a strong bactericide. Results are similar to the chemical products that are normally added.

Saline electrolysis is a reversible process, meaning that once active elements react with organisms present in the water, it reverts to common salt and water.

The equipment includes several electronic monitoring probes and regulation control and an electrolysis cell through which the pool water circulates and which is installed in the filtering circuit return.

If the salt water chlorinator equipment is left to work permanently, it will not be necessary to change the swimming pool water for several years (8 to 15 depending on its use). You will therefore be collaborating with environment preservation policies and water management and saving.

ATTENTION

Before installing the PTGEM salt water chlorinator, please read this manual carefully. If you need to clarify any point or have any doubts, please contact your dealer.

In order to improve the product quality, the manufacturer reserves the right to change the characteristics of its products at any time and without prior notice.

RISK OF ELECTRIC SHOCK

To prevent injuries or accidents, install the equipment out of reach of children.

Ensure that the local installation complies with the regulations in force in the country of installation. The pump timer power supply line of filtration should be protected by a differential circuit breaker with a tripping safety device of 30 mA maximum with opening distance of contact, of at least 3 mm on all the poles. Not confuse with the differential circuit breaker protecting the whole house which is about 300 to 500 mA. In case of doubt, get a qualified electrician to check the whole installation in your area installation. The installation of this equipment should be performed by a qualified person in accordance with the electrical standards in force in the country of installation.

The power supply cables and the cell must be protected against accidental damage. A damaged cable must be replaced immediately and exclusively with an original cable. Never cut or extend the cables.

It is imperative to turn off the power supply before carrying out any technical operation on the device (Adjusting parameters on the touch screen is a normal operation). Do not modify the device. Any modification may damage the device or be dangerous for people. Only qualified person should carry out maintenance or repairs in case of breakdown.

This device is intended for use in family pools and semi-commercial pools only.

The safety instructions detailed in this manual are not exhaustive. They highlight the most common risks of using electrical equipment in the presence of water. Any installation and use of this equipment should be carried out with caution and common sense.

NOT OBSERVANCE OF THESE INSTRUCTIONS MAY CAUSE DAMAGE TO THE DEVICE OR SERIOUS INJURY!

Notice that essentially: It is important to ensure that the supply cables of the electrolysis cell are tightly connected, otherwise the equipment could overheat and break down.

RECOMMENDATIONS AND SAFETY PRECAUTIONS

• The equipment should always be installed by qualified staff.
• Disconnect the equipment from the mains before performing any assembly or maintenance operation.
• Make sure that the electrical installation has all compulsory protection elements (circuit breaker and differential switch) in perfect condition.
• It is important to ensure that the supply cables of the electrolysis cell are tightly connected, otherwise the equipment could overheat and break down.
• Ensure that the heatsink wings (in the rear part of the power supply controller equipment) are not blocked and that air can easily circulate through them.
• All the PTGEM equipment incorporate protection systems against short circuits in the cell, absence of water detector and other safety systems that give an acoustic and visual alarm in the event of any anomaly. However, for optimum results, you should ensure the correct hydraulic operation of your swimming pool.
• Equipment housing has IP65 protection. However, it is highly recommended not to install the equipment directly exposed to sunlight.
• Corrosive environments may reduce the lifespan of the equipment. Do not leave open containers with acids near the equipment.
• Although the equipment will start to operate with lower amounts of salt, the optimum production of salt will be reached with concentrations of over 4kg/m3. We recommend a concentration of 5Kg/m3 to offset small losses of salt occurring when cleaning the filter, the effect of rainfall, etc.
• We recommend using salt that is especially prepared for use in salt water chlorination installations, as it is especially prepared for rapid dissolution and to achieve optimum results. You can find it at retailers specializing in swimming pool products.
• ATTENTION: When adding salt to the swimming pool, first disconnect the chlorinator (position OFF), and start-up the filter for 3 or 4 hours, in order for the salt dissolving and not to overload the equipment. Once dissolved, switch on the chlorinator. It is advisable to add salt to the swimming pool gradually, in 2 or 3 times so as not to exceed the recommended amount. We also recommend not to add salt near the drain, to avoid undissolved salt from circulating in the water circuit.
• The effectiveness of chlorination and the quality of water for healthy bathing, depends largely on the pH of the water. Therefore, it should be checked regularly and adjusted as necessary.
• There are other parameters which should be considered for the correct operation of the salt water chlorinator. We recommend an in-depth analysis of the water when installing a salt water chlorinator.

The power supply CONTROLLER BOX

Choose a location that is easily accessible, close to the pump timer, far apart 2 meters maximum from the chlorinator cell. Install the controller box vertically, far enough away from the pool to comply with the regulatory distance in force in your country. Do not cover.

The installation area should be dry and properly ventilated (maximal ambient temperature of use: 35℃), protected from rain, splashes, water spray, and UV radiation.

ACID OR ALKALI STORGE TANK

Ensure that the pH corrector product container is kept in a place sufficiently remote from any electrical equipment and any other chemical product.

INSTALLATION OF THE EQUIPMENT

• Place the chlorine cell in a vertical position with electrical connections facing upwards. If this is not possible, it can be assembled in a horizontal position, ensuring that the small auxiliary electrode faces upwards.
• Place the chlorination cell in the highest position possible of the purification circuit and always after the filter.
• If possible, it is recommended to install the cell with a by-pass system with its corresponding shut-off valves. This is to facilitate maintenance of the cell.
• Do not place the REDOX probe (Standard configuration for automatic models) near the chlorinator cell, as faulty readings could be made owing to the proximity of the electrolysis circuit. Always try that there is at least half a meter of water flow distance between the probe and the chlorination cell.
• The REDOX probe (TDS probe) should be installed after the filter, but if with this layout it is not possible to keep a minimum distance from the cell, it should be assembled before the filter. In this case more frequent maintenance of the probe is required.
• A good earth connection is essential. Use a differential relay with max. 30mA of sensitivity, I strongly recommend you place an earth connection kit between the electrolysis cell and the redox probe.

The equipment continuously measures the bactericide level of water through this probe, by means of a “Redox” probe (TDS probe), simply adjust the required level and the equipment automatically maintains the level of disinfection by adjusting the production of chlorine to the real needs of the swimming pool.

The screen shows the “Redox” level (bactericide capacity) present in the swimming pool and PH numerical value.

The potential RedOx (Reduction Oxidation) or ORP (Oxidation Reduction Potential) is the electrical voltage that indicates the oxidation capacity or reduction of a solution. In swimming pools, the oxidation capacity is directly related to the bactericide power of the water, which is directly related to the concentration of free chlorine in the pool.

This probe enables you to adjust the equipment in AUTOMATIC operating mode.

Similarly, the equipment continuously measures the PH through PH probe, the acid pump automatically starts and stops running based on the pH measurement value, keeping the pH value of the swimming pool water near the set value.

About pH Alarm

When the acid pump works continuously for more than 2 hours (which can be adjusted) and the pH value of the pool water does not reach the set value, the pH adjustment system will issue an alarm.

This could occur for the following reasons:

• The acid tank is empty and therefore pH corrector is not being injected into the swimming pool.
• The pH probe is dirty or worn, and cannot read the real value correctly.

However, what could occur, particularly when starting up the equipment for the first time, is that the real pH of the water is a long way from the set value. The alarm can be disabled if it is calculated that the pump needs to work continuously for several hours to correct the pH. However, it is recommended to enable the alarm once values near the set values are reached.

A proportional control automatically adjusts the pH without the need for controller adjustments. The pump will start up every minute and with a variable operation time of between 0 and 60 seconds.

About production of Cl₂

Configuration of the maximum production of chlorine.

From 0% to 100% and use the + or – key to change the value.

Note: Chlorine production may be limited regardless of the operation mode (manual, automatic) that is selected.

Adjustment of the set value (Max. ORP) ORP Mode in which a Redox probe is installed.

In this case, adjust the oxidation potential to the required level. For private swimming pools that are not used frequently, 650 mV is a sufficient value 700 mV is the suitable value for the majority of swimming pools. However, the best way to adjust the optimal ORP value is to analyze the water and determine the ratio between ORP and PPM, because there are some differences between several types of water.

NOTE: Whether it’s manual or automatic series products, you can adjust the production percentage from 0% to 100%.

Stop-start control:

This mode enables you to keep the equipment on permanently, so that when the filtering pump starts up, it will instruct the chlorinator to start-up.

Programming the spotlights of the pool through the auxiliary relay: Remember that the relay is potential free, and therefore the circuit should be supplied externally.

– Filtering control through the auxiliary relay:The filtering pump can be controlled through the auxiliary relay （Remember that the relay is potential free, and therefore the circuit should be supplied externally）.

– Cover detection:If your swimming pool has an automatic cover, it is possible to configure the salt chlorinator to detect it. In this way, the chlorine production will be limited to 20% when the cover is on, in order to avoid an excess of chlorine which can damage the cover.To connect the cover to the chlorinator, place the two contacts from the limit switch and connect them to the 3 and 4 inputs as shown in the following picture:Bear in mind that the cover switch can be Normally Open (N.O.) or Normally Close (N.C.).- If your limit switch is “Normally Open”: Keep connected the J2 Jumper which comes from the factory.- If your limit switch is “Normally Closed”: Remove the J2 Jumper.In case of swimming pools without automatic cover, just leave the J2 Jumper as it comes from the factory.- CoverThe equipment may detect the presence of a cover on the swimming pool (only for automatic covers). In this case, it is only necessary to place the limit switch of the cover in the terminal block, as indicated in the section on electrical installation.On placing the cover, the chlorinator automatically reduces production to 20%. This variation will be reflected in the production %.

If chlorination is carried out with the cover in place, when it is removed, the pool should not be used straightaway. It isbetter to wait ½ hour for any vapours between the water and cover to dissipate.

– Change of languageFrom the configuration menu select “Language”, press the OK button, and once the required language has been selected, press the OK button and EXIT.– CleaningThe equipment includes an automatic cleaning system, based on reversing polarity in the electrolysis cell. These cleaning cycles are performed regularly.The time between cleaning (in hours) can be adjusted depending on the water hardness of your swimming pool.

It is possible to select cleaning intervals from 4 to 24 hours.

-Flow switchThe flow sensor detects whether or not there is water flow in the piping. If it detects that there is no flow, the production will stop, and an alarm will sound accompanied by a red warning LED. Once the flow has been reestablished, the equipment will return to normal operation.4.2.4.8 Acid / AlkaliWith this option you can select the type of pH corrector to be used in your swimming pool.Attention: It should be selected correctly otherwise the dosing system will work opposite to expected.-Acid: Select this mode if you are going to inject pH reducer into the swimming pool (default mode).-Alkaline: Select this mode if you need to inject pH increaser into the swimming pool.Access this option from the ” User Settings menu “. To change this mode to another one.

4.2.4.10 Night AlarmWhen an alarm occurs, the unit stops its production and shows an acoustic and visual alarm to indicate that it’s necessary to correct the problem.However, it is possible to keep the alarm silent between 10:00 pm and 9:00 am, selecting the option Night Alarm = N.

– Priming the pump.Once the acid pump has been installed, it should be primed to eliminate the installation air.Go to the “pH” menu and select “Manual”. Keeping the “OK” button pressed, the pump will be running. Keep the pump running with the “OK” button until the liquid has passed throughout the tube until injection.– Automatic shutdown and error message.If the acid pump shuts down and the message “pH ERROR” appears, the pump has been operating too long without the pH value lowering to the required level. The causes could be:-There is no acid.-Problem in the pump or in the acid duct.-The probe or probe cable are damaged.NOTE: to cancel the error alarm, press the “OK” button

– ClockThe equipment has a time clock, which will be taken as the reference when programming times of the auxiliary relay. The clock keeps the time setting even when the equipment is without supply.
