“NATURAL CHLOR” SALT CHLORINATOR

Congratulation on choosing an “ Natural Chlor” chlorinator.
You r «Natural Chlor» chlorinator has been manufactured to the strictest and will correctly maintain the chlorine connect of any swimming pool under normal use.
Please read the following instructions carefully in order to learn more about the features, operation and correct maintenance of your «Natural Chlor» chlorinator.

PREPARATION OF THE WATER IN YOUR POOL

The water in your pool will be clear and clean if the corresponding analysis gives the following results:

The stability of the water depends on the relationship between its PH, hardness, alkalinity, solids in solution and the water temperature. It is necessary to establish the correct balance before connecting the chlorinator to the water in your pool

The analytical kit is the only way to verify the level of residual chlorine and the chemical balance of your pool. We recommend you check the water in your pool regularly and adjust it as necessary in order to keep it clear and transparent.

ADDITION OF SALT

Salt has to be added to your pool in the proportion of 50-60 Kg of salt for every 10 m3 of water. The salt is added all around the water’s edge in order to facilitate dissolution. As salt is heavier than water, it will lie at the bottom even though it will seem to have dissolved. In order to ensure adequate distribution it is a good idea to sweep the bottom of the pool and keep the water filter operating for 24 hours. All of this must be done before the chlorinator is switched on.

Contrary to what you might think, ”Natural Chlor” chlorinator will not use u o the salt as it produces chlorine. What happens is that the salt is electrolyzed and converted back into ordinary salt once your pool has been disinfected. Nonetheless, the use of a filter and its subsequent cleaning showers will reduce the level of salt in the water and whenever the water level in the pool is increased, the salt concentration will be reduced.

While salt is being added to your pool, your “Natural Chlor” chlorinator must be switched off until all of the salt is completely dissolved and distributed throughout the pool water in order to prevent costly damage to the electrodes and your chlorinator.

ASSEMBLY INSTRUCTIONS

1. Calculate the pool’s capacity. Add 5-6 Kg of salt per m3
2. Balance the Ph between 7.2 and 7.6. In fibreglass pools, 6.8 – 7.0.
3. If the water has been newly added, use 1 Kg of CHLORINE STABILISER FOR EVERY 25 CUBIC METRES.
4. Open the filter. Clean it and add sand, 2 or 3 centimeters above the upper tube (if it is a diatomaceous filter, do not touch it).
5. Electrical wiring. Check the 220 V power socket, your «Natural Chlor» chlorinator operates at 210-230 V and requires earthing. Connect the chlorinator through the timer in order to allow the chlorinator to switch itself on and off automatically with the water filter.

The cell should be installed at the filter outlet, after the heater (solar heating) valves, etc.… There must be enough room to allow the cell to be dismantled for cleaning (see diagram below and graphic on page 28).

The control panel must be installed close to the water filtering system. The ideal location is on a wall offering protection against rainfall, splashing or accidental overflow.

Note: The housing of the cell is adapted for pipes of 50 mm
Please ensure that the cable from the control panel is correctly attached to the cell in accordance with the colour coding.
Place the control panel higher than the cell but not more than 1 meter away so as not to stretch the cable between the panel and the cell. Similarly, it can be placed upright on the ground.
Do not install the cell above the pump. Place it in the water return circuit or returns pipes.

MAINTENANCE

CLEANING

Reverse Polarity Chlorinators have self-cleaning cells which means the maintenance required is minimal. In exceptional cases, when the calcium content is abnormally high, the chlorination may not totally remove all of the deposit. In this case, the calcium level must be adjusted to normal levels and the cell must be cleaned.
Procedure: Turn off the chlorinator, disconnect cell cable, and remove cell. The dirty cell should be placed in a 20% solution of hydrochloric acid (8 parts of water to 2 parts of hydrochloric acid) You should make sufficient dissolution to be able to immerse the cell completely. Don´t immerse the cap where the connections are located. For safety please remember to add the pool acid to the required amount of water, not the water to the acid. The cell can also be cleaned using a pressurized water hose. Do not use metal tools to scrape off any remaining on the plates

Calcium deposits will react with the Hall producing gas. When gas production has stopped, it means that the cell is completely cleaned and all the calcium has dissolved. Rinse in fresh water as soon as possible- leaving the cell in Hal solution for a longer period will damage the cell! When cleaning is complete, dry the connections and reinstall the cell.

Note: Do not maintain the cell in the dissolution of acid more than 5 minutes

The operation of the cell without water flowing through it may be dangerous due to the creation of gases, which can accumulate in the filter and cause damage.

STOP
In exceptional cases (high temperatures), filter the water for three or four hours more every day if the formation of algae is observed.

Operate the water filter as long as necessary in order to ensure that the water in the pool is filtered once a day. The time required will depend on the number of liters processed by the filter and the pump every hour. As a rule of thumb, the following may be helpful

If your pool is used intensively outside the normal hours indicated on the automatic filtering system, we recommend you operate the water filtering and chlorinating system during these additional periods

Note: For public pools (Hotels…) it would have to work the hours necessary to maintain the chlorine level according to rules.

OPERATION OF THE WATER-FILTER

It is necessary to have proper circulation of water in order to ensure the efficient distribution of chlorine. It is important to use the corresponding skimmers and drain outlets to improve the water flow.

Check and adjust the Ph levels between 7.2 and 7.4 (fiberglass pools, 6.8 – 7.0) and the chlorine levels to between 0.6 and 1.2 ppm two or three times per week. Check the level of sand in the filter every two years and clean the filter every fortnight.

Switch off the system whenever:

• Water is not circulating.
• The filter is being washed.
• The pool is emptied.
• THE WATER IS FROZEN.
• You are cleaning the cell.

TECHNICAL SERVICE AND SPARE PARTS

Natural chlor , S.L. or your local distributor have spares available for your chlorinator. The use of unauthorized spare parts and the manipulation of the  apparatus by personnel not approved by “Natural Chlor ” may lead to severe damage to your chlorinator and it would cancel your warranty.

EXPLANATIONS OF FUNCTIONS OF POWER SUPPLY

The «Natural Chlor» chlorinator is fitted with sophisticated electronic diagnostic system to maximize the life of the electrolytic cell. This system incorporates an easily – understood LED display panel, indicating the action to be taken at all times.
A summary of the action to be taken whenever any of the lights on the casing control panel are on is given below.

1. Single press of the button decreases chlorine (Cl2 ) production by 10%. In order to turn OFF the chlorinator it is necessary to press the button several times to make sure all Chlorine Production Indicators are OFF.
   Note :The chlorinator produces always to 100% When you press the bottom what you do is decrease the time of chlorine production no the quantity of chlorine.

2. Low Salt (Nacl) Warning indicator. Salt concentration should be increased to 5000 – 6000 ppm to satisfy chlorine production. If the light flashes, the level of salt is below the minimum, the chlorinator will turn off slowly automatically.

3. Chlorine Production Indicators. There are 10 indicators. Each indicator corresponds to 10% of Cl2 production.

4. High Salt (Nacl) Warning indicator. When the salt level is high this light will go on- add fresh water. If light is flashing the chlorinator will shortly turn off automatically as salt levels exceed maximum. Salt concentration must be decreased to 5000 – 6000 ppm.

5. The Chlorinator has power.

6. If the water flow indicator is flashing, the chlorinator is in the Stand By mode and there are no water flows through the cell. Please make sure the pump is running and there is water passing through the cell.

7. Single press of the button MAX (8) increases Cl2 production by 10%. When all lights are ON the Cl2 production is 100%.

TROUBLESHOOTING GUIDE

1. There is no current:
   a) Check that the meter is plugged in.

2. Low reading on the chlorine production indicator.
   a) Insufficient salt level in the pool.
   b) Electrodes need to be cleaned.
   c) Electrodes worn down.

3. The residual chlorine in the pool is low:
   a) Chlorinator is not working long enough.
   b) The level of the chlorine stabilizer is too low.
   c) The electrodes need to be cleaned.
   d) The Ph of the water is too high.

Note: In situations where low chlorine is detected, the chlorinator can be very quickly tested by taking a water sample from the skimmer box and conducting a chlorine test. Then conduct a chlorine test by taking a water sample from the eyeball return. The chlorine reading from the pool eyeball should be considerably higher than in the skimmer box at least 1%.

WARRANTY

1. Electrolytic cell and rectifier for domestic and industrial units, 2 years.

2. The seller declines all liability in the following cases:
   a) The instructions contained in the present operating manual are not respected.
