INSTRUCTIONS FOR PREPARING CHLORINE SOLUTIONS

If the concentrated chlorine solution is prepared manually, the following procedure must be strictly followed:

1. Always use a clean preparation container that should only be used to prepare chlorine solutions.
2. Calculate the amounts of water and calcium hypochlorite needed to achieve the desired chlorine concentration (see the table below).
3. Add at least 90% of the required amount of water (see table below) to the container.
4. Slowly add the required amount of calcium hypochlorite to the water while agitating the solution.
5. Add the remainder of the required water to bring the total volume to the desired level.
6. Continue agitating for at least 15 minutes to ensure that the product is completely dissolved.

COMMERCIAL POOLS AND SPAS

• Do not allow anyone to enter the pool if the concentration of available chlorine is above the national limits, or in the absence of this, 3 mg/l for swimming pools and 4 mg/l for spas.
• For perfectly balanced water, maintain alkalinity (T.A.C.) at a level between 60 and 120 mg/l.
• In an open-air pool, maintain stabiliser concentration between 25 and 50 mg/l.
• Check the chlorine level in pools regularly because UV rays can partially degrade the chlorine.
• Adjust the pH between 7.0 and 7.4.
• Check that the filter is in operation.

• Permanent chlorination:

• Check that the preparation tank and the pump do not contain any stabilised chlorine (trichloroisocyanuric acid or sodium dichloroisocyanuratee: check the labels).
• Prepare chlorine solutions following the dosing table and instructions.
• Adjust the injection to maintain a level of chlorine that meets local regulations. In the absence of regulatory obligations, it is recommended to maintain a level of active chlorine between 1 and 3 mg/l for a pool and between 2.5 and 4 mg/l for a spa.

• Shock chlorination when opening the pool and if the water is green/cloudy: Adjust the injection rate to reach a concentration of available chlorine equal to 10 mg/l.
