Diirections of Use: Prior to using this product, ensure PH level is in the ideal range of 7.2 to 7.6. You may need to shock dose before use to establish a chlorine level in the water quickly. You can use Sodium Hypochlorite (liquid chlorine) or Calcium Hypochlorite to achieve this. Ideal for pools up to 5,000 gallons (22,700 Litres). Remove the two perforated sections of the label marked with ’tear here’ and also remove the two security seals. To choose your setting and therefore the rate that the dispenser will dissolve in the pool. As a guide (only) use the x small setting for pools up to 3,000 gallons and small setting for pools above 3,000 gallons. If Free Chlorine levels are outside the desired 1-3mg/l (ppm) range - either too high or too low then adjust the base to expose to more chlorine or less. This is only a guide, as a number of factors affect chlorine level including bather load, weather, rain etc. Place the dispenser in an upright position in the pool and hold for a few seconds until the cartridge fills with water then release to float on the pool surface. Do not submerge the dispenser completely or block the vent holes. The dispenser will tip over when spent. A tilting dispenser at a 45 degree angle is an indication of imminent replacement required and sanitiser output diminishing. When removing the spent dispenser, cut open the base and place remianing tablets in the weir or skimmer basket.
