  • Page 2: Installation

    Thank you for purchasing a Nature Express pool sanitizer. Please read through the ® entire manual before installing your new unit. Installation Nature Express easily installs on your pool’s return line. You will need to use a cordless or electric drill to install the vessel. Nature Express components: (1) winterizing cap, (2) outer housing, (3) 2” clamp assembly w/gasket (I/G only), (4) 1-1/2” clamp assembly w/gasket, (5) flow diverter, (6) Express cartridge, (7) hole saw, (8) nuts and bolts, (9) silicone tube, (10) rigid PVC adapter (A/G only). 1. Decide where to install the Nature vessel. It must be installed: • After the filter on the main return to the pool. • Before or after the heater (downstream of solar heating systems). • Before any chemical dispenser or the discharge of any off-line chemical dispenser. IMPORTANT: Install a check valve before chlorinators to isolate the Nature vessel from possible backflow of highly chlorinated water.
  • Page 3 The pressure must be released before you begin work. Please see your pump/ filter owner’s manual for further instructions. 4. Close any valves. If your pool filtration equipment is below the water level of the pool, you will either need to close the return valve or use winterizing plugs at the skimmer and return fittings to prevent excessive water loss. Contact your Nature dealer or Zodiac Customer Service at 800-822-7933 for more information. For Aboveground Pools Aboveground pools are often plumbed with flexible or corrugated pipe. These systems require use of the rigid PVC adapter included with Nature Express for aboveground pools. The adapter fits most filtration systems.
  • Page 4 7. Install your Nature Express on schedule 40 PVC pipe only. Failure to heed ® this warning can result in equipment failure. Position the clamp assembly on the pipe, with the arrow pointing in the direction of the flow of water and hand tighten the nuts and bolts. Tighten nuts an additional 1/4 turn using a wrench or socket. Do not over-tighten. Note: The 2 halves of the 1-1/2” clamp assembly will not touch when properly assembled. A gap of roughly 1/16” is normal. 8. Insert the hole saw into a drill. Using the hole in the top half of the clamp assembly as a guide, cut a hole in the pipe.
  • Page 5 9. Insert the flow diverter into the clamp assembly and snap it into place. Snap the outer housing onto the clamp assembly. 10. Spread silicone around the o-ring just above cartridge threads. 11. Thread the Nature Express cartridge into the clamp assembly. Set the date ® reminder. 12. Open any valves that you closed and turn on your pool pump to verify that there are no leaks. The small pellets inside the cartridge dome provide evidence of water flow through your Nature Express. If a leak is present: turn off pump, close valves, and remove Nature Express and assembly. Remove any PVC burrs, replace clamp assembly without over- tightening, and re-install cartridge. 13. Refer to your Nature Cartridge Owner’s Manual for cartridge start up procedures.

  • Page 6: Operation And Maintenance

    Operation and Maintenance Filtration and Circulation Follow the manufacturer’s directions for keeping the circulating pump in good working order and operate it at least six (6) hours a day. Consult your Nature dealer for ® optimum run times. Check pool filter periodically and clean as recommended by the manufacturer. Replacing The Cartridge Use the month indicator ring on the top of the unit to identify the date on which the cartridge should be replaced. A Nature Express cartridge lasts for six (6) months. To replace the cartridge: 1. Shut off your pool’s pump and filter. Close any valves between the filter and pool to prevent draining the pool. 3. Unscrew and remove the old cartridge. 4. Screw the new cartridge into housing and clamp assembly. 5. Rotate the install/replace ring located on the top of the cartridge to the appropriate month.
