The letters in parentheses refer to a diagram on page 5. Under normal pump and filter pressure conditions for concrete pools, the flow rate to the inlet side of the purifier is 95-303 L/min which will allow proper flow through the cartridge. Important: : If your pump system is designed to produce flow rates greater than 303 L/min (80 GPM) or if plumbing is greater than 38mm (1.5 in) ask your dealer about installing in a bypass configuration. Bypass Installation This 38 mm (1.5 in) Nature2 Purifier system may need to be installed in bypass to the filtration system if plumbing size is greater than 38 mm (1.5 in) diameter or if flow rates are greater than 303 L/min or 80GPM. The Nature2 Purifier is installed on a bypass loop after the filter and always before a chemical dispenser, if equipped, as shown below. If the Nature2 Purifier is to be installed below the water level of the pool, precautions must be taken to prevent the pool from draining during installation and during cartridge change. Valves should be installed to isolate the system for these situations. Installation Equipment you will need: • a set of shut-off valves or rubber winterizing line-plugs to use during installation or cartridge replacement to prevent draining (used in step 4 below) • a filter connector hose of the same diameter as the other hoses on your pool equipment (used in step 6) • two 38 mm (1.5 inch) male hose adapters wrapped with teflon tape • two hose clamps 1 Decide where to install the Nature2 Purifier. It should be installed: • on a concrete slab to support the weight of the vessel, • after the filter on the main return to the pool, • before or after the heater, • before any chemical dispenser or the discharge of an off-line chemical dispenser. 2 Hand-tighten both the hose adapters into the base of the Nature2 Purifier (F). The purifier is now ready to be installed. 3 Run the pump with a clean filter and under normal operating conditions. It is important to start with a clean filter. 4 Turn off the pump and totally isolate the equipment (to prevent draining the pool) by plugging all lines running from the pool to the equipment, closing in-line valves, and/or using the winterizing line plugs to seal off the skimmer pipe and all return inlets. You are now ready to insert the purifier into the pool’s lines. 5 Disconnect the hose on the outlet side of the filter. Connect it instead to the outlet side of the purifier. 6 Install a new section of connector hose between the outlet side of the filter and the inlet side of the purifier. Use the hose clamps to secure the two ends of the new section of hose. The new installation should look like this: Pool → Pump → Filter → Purifier → Pool. 7 Remove plugs or open all valves used to isolate the filter. Set the cap (C) in place and screw on the locking ring (B) until it is snug. Do not overtighten the cap. Check that all connections are secure. Important: Do not install the Nature2 Cartridge (E) yet. 8 Turn on the pool’s pump, check for leaks and repair any leaks you find. 2 To create the bypass: 1 Install a “T” in the return line to allow water to divert to the Nature2 Purifier. This “T” is then connected to the inlet of the purifier. 2 Install a control valve in the return line after the first “T” and before the second “T”. 3 Fully open any valves (including the control valve) that were closed to isolate the purifier. 4 Start the pump allowing water to pass through the newly plumbed system. The control valve in the return line between the two “T”s will control the flow through the purifier. Note: For flows in excess of 303 L/min or 80GPM with the Nature2 in bypass, do not exceed a 10.3 kPa increase in filter backpressure. Once 10.3 kPa is reached in this situation the flow is correct through the purifier. 5 Check the purifier for leaks and fix or replace any fittings. 6 Follow the start up procedures. 2 Balance the Water To find out if your pool water is balanced: • take a water sample to your dealer to be tested regularly, or • ask your dealer to recommend a pool test kit for water balance. Balance pool water before installing purifier cartridge. • pH 7.2-7.8 • Total hardness 200-300 ppm • Total alkalinity 80-120 ppm Consult your Nature2 Dealer for specific water balance instructions. Element: pH Range: 7.2-7.8 If it’s too low: The surface of your pool can become etched. Metal parts in the pump and plumbing will corrode. How to fix: Add pH increaser. If it’s too high: “Scale” forms on the surface of your pool. The water can become cloudy. "Scale" forms on your pool equipment. How to fix: Add pH decreaser. Water is less stable. In plaster pools, the calcium is taken out of the plaster, causing the surface to deteriorate. How to fix: Add calcium hardness increaser. If it’s too high: Rough, discolored deposits (“scale”) will form on the pool surface and inside pool equipment. How to fix: Drain or dilute the pool water. Consult your dealer. If it’s too low: It provides no buffer so that you constantly get fluctuating pH readings, which can damage equipment and pool surfaces. How to fix: Use an alkalinity increaser. If it’s too high: White deposits (“scale”) form on the tile line. The plaster on pool surface becomes rough or discolored. The water becomes cloudy or milky white. How to fix: Add acid to bring alkalinity down. Element: Calcium Hardness If it’s too low: Range: 200-300 ppm Element: Total Alkalinity Range: 80-120 ppm 3 Start Up Before starting up a new Nature2 Cartridge, clean debris and algae out of the pool and equipment. Important: Do not install the new cartridge until the pool water is chemically balanced. 1 Install the cartridge after water is balanced. 2 Shock the pool to burn off contaminants and to activate the cartridge. Follow label instructions of shock product being used. 3 Run the circulating pump either: • 24 hours a day for 4 days, maintaining 1-3 ppm free available chlorine, or • 6 hours a day for 14 days, maintaining 1-3 ppm free available chlorine. 4 Let free available chlorine residual drop but not below a minimum of 0.6 ppm once start-up period is completed. 4 Follow the Recipe Low-Chlorine Recipe (0.6 ppm free available chlorine minimum) Once the 4-day or 14-day start-up period is done, allow the free available chlorine residual to drop but not below 0.6 ppm, then: Ingredients: • Nature2 Purifier When: What to do: Every day Run pump and filter at least 6 hours every day. • Chlorine granules, tablets, liquid or generator Once a week Balance pH and total alkalinity. • pH and total alkalinity adjusting chemicals Twice a week Check chlorine residual, add chlorine to maintain a minimum of 0.6 ppm free available chlorine. As needed • If water is hazy, shock. Follow product label instructions. • After heavy use or rainstorm, shock is recommended. • Add cyanuric acid (stabilizer) to maintain 50 ppm. • Calcium hardness increaser, if needed • Water test kit • Cyanuric acid 3 5 Provide Filtration/Circulation To manage: You need to: Circulation Follow the manufacturer’s directions for keeping the circulating pump in good working order and operate it at least six hours a day. Consult your Nature2 dealer for optimum run times. Filtration Check the pool’s filter periodically and clean it as recommended by the manufacturer. Troubleshooting Guide Consult your Nature2 Dealer for additional assistance. Problem What to look for Treatment Cloudy water Poor filtration Slow filter turnover rates Frequently caused by improper start up. See section on Start Up. 1 Backwash and clean filter. 2 Run filter for 24 hours. 3 Increase run time per day. Algae growth Hazy pool water; may have slightly green appearance. Shock water (with dealer’s guidance) and brush pool walls. Unbalanced water 1. High hardness 2. High TDS (total dissolved solids) 3. High pH 4. High total alkalinity Balance the pool water Green algae Pea green color; attaches to pool walls; sometimes colors the entire body of water 1 Check pH and adjust if necessary. 2 Shock water and brush pool walls. 3 Repeat steps 1 and 2 until algae is gone. Black algae Black spots on pool walls Mustard algae Yellow or brown film on steps or walls 1 2 3 4 5 Algae Brush affected areas. Shock water. Add algaecide. Vacuum pool. Repeat steps 1 through 4 until algae is gone. Note: Regular algaecide treatments are recommended for outdoor pools that experience persistent algae problems. Do not use algae treatments containing either copper or sodium bromide. Stains Scale Blue/green Copper or iron from pool equipment corrosion or water supply 1 2 3 4 5 6 7 Adjust pH and total alkalinity to ideal ranges. Vigorously brush stained areas. Add sequestrant. Run filter. Twelve hours later, shock the pool. Test and balance water. Test pool water for dissolved metals. Red/brown Iron or manganese from equipment corrosion or water supply. Black Manganese in water supply. Metal tarnishing High native mineral content in water; unbalanced water Clean with soft cloth and mild detergent. Test water for minerals; use a sequestrant; maintain water balance. Crusty deposits on pool surfaces High pH and high total alkalinity Adjust pH and total alkalinity to ideal ranges. High TDS (total dissolved solids) or high hardness levels 1 Replace a volume of pool water with water low in calcium and dissolved solids. 2 Use sequestrant to prevent scale buildup if high hardness levels are a continuing problem. Equipment The purifier leaks A. O-ring missing or improperly seated or No flow to purifier 4 Lubricate O-ring with Teflon or silicone lubricant. Note: Do not use petroleum-based lubricants (will void warranty). Be sure O-ring is seated properly before securing housing cap. B. Faulty plumbing Repair source of leak in plumbing. Dirty filter (one indication: pressure 55-69 kPa higher than normal) Clean or backwash filter so operating pressure is always within 48 kPa of a new filter. Replacing the Nature2 Purifier Cartridge Winterizing Your Pool Use these steps as a guide. Consult your dealer for specific information on your area. Use the month indicator ring (A) on the top of the unit to identify the date on which Warm Climate the cartridge should be replaced. 1 Reduce the number of hours the pump runs since the cooler weather decreases the spread of algae and other pollutants. A cartridge lasts six months from the date of installation under normal operating To replace the cartridge: 2 There is no need to shock the pool during cool weather unless the water becomes cloudy (as may occur after a winter storm). See Cloudy Water in Troubleshooting section. 1 Shut off your pool’s pump and filter. Cold Climate 2 Close any valves between the filter and pool to prevent draining the pool. 1 Check total alkalinity and pH of pool to make sure that they are in proper balance. conditions. 3 Unscrew the locking ring (B) by twisting counterclockwise until the ring and the cap are free of the housing base. 2 Vacuum the pool bottom to remove any debris or other potential contaminants. 4 Lift out the old cartridge. 3 Shock the pool to clear the water. 5 Insert the new cartridge. 4 Add a winter algaecide following manufacturer’s instructions. 6 Set the cap and locking ring in place and screw the ring clockwise until it is snug. Do not overtighten. 7 Position the month indicator ring (A) on the cap so that the current month is visible in the installation window. 8 Open any valves that were closed to isolate the Nature2 Purifier in step 2. Important: Do not use a winter algaecide with copper in it. This will void the Nature2 no-stain warranty. 5 Backwash the filter. 9 Restart your pool’s pump. Check for leaks and fix any leaking fittings. 6 Drain part of the pool water. The amount to drain varies from one part of the country to another. Consult your dealer for advice. 10 Follow the start up procedures described on page 3. 7 Winterize the purifier as follows: • Unscrew the locking ring (B) and remove cap from the purifier base. • Remove the winter drain plug (G) and drain the water completely out of the base of the purifier. • Lift out the purifier cartridge and dispose of it. • Set the cap O-ring (D), the cap and locking ring in place and screw it tight. • Store the purifier with your pool equipment, indoors if possible. 8 Winterize the pipes with pool antifreeze following manufacturer’s instructions. 9 Drain the water out of all equipment (pump, filter, etc.). 10 Store all baskets, hoses and cleaning equipment, indoors if possible. 11 Cover the pool with a winter cover.
