Installers must attend NuWater training and be certified by Natban Ek at Ek Engineering (www.ekengineering.net)prior to installing this system. 3. OSCAR supply kits are available through H.D. Fowler, contact Dennis Graff,phone: 1 (800)927-5699 or Ferguson Waterworks(Silverdale)contact Zach or Daryl 360-697- 1510. Control panel will be pre-programed by supplier. 4. Order NuWater-O kit that does not come with a control panel. Control panel comes with Oscar kit from suppliers above. 5. OSCAR Sand media must meet or exceed ASTM C-33 standards. 6. Install drainfield level with contour of the ground. 7. Install drainfield during dry weather and soil conditions; any soil smearing must be eliminated by hand raking. 8. Tanks must have risers to the surface as required by Mason County to ensure easy access for future operation and maintenance. 9. Headworks must be in boxes accessible from the surface for future operation and maintenance. 10. Ensure any trees and shrubs are removed, grass is cut short and then scarify surface of ground in drainfield area to prep for drainfield. 11. Ensure 6"minimum cover sand media over the drip irrigation tubing. 12. Install audio/visual high-water level alarm. Redundant off switch not required. 13. Install return line from headworks back into the pump chamber. 14.Encase all water lines within 10' of drainfield and under any driveway/parking areas. 15. Divert all storm water runoff and house downspouts away from on-site sewage system. 16.No curtain drains allowed within 10' of the up-slope edge or 30' of the down-slope edge of the drainfield and reserve area 17.Inspect floats,clean filters,and test high water level alarm every 6-12 months as needed. 18.
